The best non-toxic window coverings are natural untreated fabric, natural fiber roll-down blinds, non-painted aluminum blinds, and aluminum screens.
For blackout shades, bamboo shades with liners, polyester curtains, hemp, cotton, and paper pleated shades can be considered.
I avoid PVC roller shades or curtain backing, flame retardant treated fabrics, wrinkle-free finishes, and wood and aluminum blinds with finishes that offgas.
If you’re looking for non-toxic window frames, you can find that article here.

1. Non-Toxic Fabric Curtains
Fabric curtains are usually treated with wrinkle-free chemicals and flame retardants.
Natural fabrics do break down in UV light but are a healthier option. Look for Oeko-Tex 100, organic, or GOTs Certified fabrics to guarantee that they don’t use chemical treatments.
Good Brands
1. MagicLinen uses 100% OEKO-TEX-certified European flax linen. Their blackout curtains have a backing layer of polyester.
2. Anchal makes a single layer 100% GOTS Certified organic cotton curtain.
3. Rawganique makes organic hemp and organic linen curtains as well as organic cotton blackout curtains. They offer dye-free, bleach-free options.
4. Barn & Willow uses Belgian Linens (usually grown without pesticides) and certified organic cotton fabrics.
Other:
The linen options I have found on Amazon are either a linen polyester mix or polyester made to look like linen.
2. Non-Toxic Blinds
Types And Brands:
Bamboo Blinds
“Green” versions of blinds include bamboo roll-down blinds that are not treated with chemicals like those from Earthshade and Blinds Chalet. Check to see what the backing is and order samples. Bamboo blinds come in different looks, and other grasses can be woven into the blinds as well.
1. EarthShade is a company that goes above and beyond and is great for chemically sensitive folks.
2. Blinds Chalet makes bamboo shades and was happy with the samples (these really need a backing unless you want just minimal privacy).
Wooden Blinds
I have not found wooden blinds with a 0-VOC finish since this is so hard to accomplish with something that holds up to UV. Real wood blinds are also prone to warping. Real solid wood is best used as shutters.
Real wood blinds made of basswood are extremely light. From an aesthetic point of view, they are almost impossible to differentiate from the composites.
1. Blinds Chalet makes real wood blinds that are very light and thin (Signature 2 inch in Carmelia is what I got samples of). I could pick up only very minor offgassing which did come to completion in a few weeks.
2. Blinds Galore – all of the thin 2 inch real wood blinds from Blinds Galore were also very low in odor, just like other major brands. Only the very sensitive would be able to pick up any offgasing. And with a bit of time, this did offgas completely.
Faux Wood Blinds
Faux wood blinds are usually polyvinyl chloride (PVC), but composite blinds can be made of safer plastics mixed with wood.
1. Blinds Chalet composites that I got samples of were very low in offgassing (Premier Composite Shutters).
2. Blinds Galore composite blinds don’t explicitly say what kind of polymer (plastic) is used. Some of them are listed as PVC and some do not indicate the type of plastic used. This brand has an American and Canadian website. I tested Bali wood blinds. They were extremely low in offgassing.
Aluminum Blinds
Aluminum blinds used to be finished with a powder-coated finish which was very safe. You can find some older blinds like this.
But currently, all metal blinds in North America, Asia, and Europe are made with a polyester-based baked-on enamel finish that does offgas in theory. But by the time I have received samples of metals blinds the offgassing has been complete.
1. EarthShade makes the only brushed aluminum blinds with no paint or coating. (At some retailers, what they are calling “brushed aluminum” does have a coating).
2. Hunter Douglas ads an anti-static additive to the coating of their blinds. This may be something like Teflon (but we don’t actually know what it is), which could offgas or leach chemicals.
Between the Glass Blinds
Between the glass is a really cool option that eliminates the worry of offgassing. The blinds are between the panes of glass.
1. Pella – if you’re getting new windows you could get your blinds or shades in between the glass. Which is a cool option that Pella offers. Here is an example.
3. Non-Toxic Blackout Shades & Curtains
Polyester Blackout Curtains
Polyester backing is one of the the most common black out lining materials. Polyester with no PVC will work for many sensitive people. It’s not perfect right out of the box, but it doesn’t take long for the chemicals to dissipate. If you can wash and/or air them out first that will help.
1. Eclipse polyester curtains from Amazon do not contain flame retardants. They can be washed and aired out, and should be good after washing and airing for most people.
2. West Elm‘s 100% polyester curtain liner is an extra layer of polyester that goes under their other curtains, it contains no PVC or foam. Like all polyester it will still have that new fabric smell but will air out with some time. West Elm has been improving their eco-credentials lately. Someone sensitive to chemicals did well with these.
3. Moondream makes 100% polyester black out curtains that are Oeko-Tex 100 certified.
Room Darkening Curtains
1. Rawganique makes two-layer Organic Cotton “Blackout Curtains”. The brown/brown color will black out as much light as is possible to black out with 100% natural and organic material.
2. IKEA Room Darkening Curtains made with 100% cotton are light-blocking. They should be washed or aired out before using if you’re highly chemically sensitive.
100% Blackout Blinds
1. Earthshade makes eco blackout shades and rollers that are probably the safest ready-made option on the market. The blackout roller shades do contain 35 parts per billion (ppb) formaldehyde (a miniscule amount) which is produced when pressing the polyester sheets together to laminate them with heat. Only the severely sensitive will need to offgas this first by airing it out. The shades have also been processed with bleach. Those are the only two treatments of the fabric.
When installed with a proper blackout system, these will get you the most light blocking of the options on the list.
2. Blinds Chalet blackout liner that goes with the bamboo shades is PVC- free. Their bamboo is also grown without pesticides and chemicals.
Simple Light Blocking
1. Paper black pleated shades are a simple and quick solution to light blocking. The company claims in an email they do not give off any hazardous chemicals (I bought the natural color version of this – it has a slight chemical smell and needs to be offgassed only for a short while). They are not that great at blocking light compared to the other options and you will need to double them up to make a bigger difference. But these are super inexpensive, easy to install quickly, and worked perfectly in my tiny house.
DIY Organic Curtains
Another really safe option would be to make your own blackout curtains with pesticide-free hemp or organic fabrics.
1. Two Sisters Ecotextiles sells organic fabrics for curtain making, including black out liners.
4. Non-Toxic Window Screens
Conventional screens are very smelly at first. They can be left outside to offgas, or aluminum screens can be used instead. Chemically sensitive folks prefer aluminum screens.
Marvin is one brand that makes aluminum options.

Did you find this post helpful? If so you can buy me a coffee to support the research behind this blog. Thank you!
Scott says
Hi Corinne, thank you for your longtime, caring website for healthy materials. If I were president of the USA, I would appoint you to head the FDA or the CDC!
You wrote above: “Between the glass is a really cool option that eliminates the worry of offgassing.”
Corinne, if you see this, could you please explain? I thought the blinds or shades could be toxic, even if there’s no new frame to worry about. What and in what context “eliminates the worry of offgassing.”? Thank you.
Corinne says
When the blinds are between the glass the glass blocks offgassing from the blinds. Though yes, in this scenario you would have new windows which all have a little offgassing themselves.
Y F says
Amazing site I discovered during research for our reno, Also purchased your Healthy Home Checklist ebook to support but I should do more considering how much of your content I’ve been reading.
Question – installing Lutron Serena shades and a bit lost. Do you know which of their fabrics would be ideal? They seem to be Greengold Certified (sadly not GOLD). With some research it seems their Sheerweave are manufactured by Phifer (we are thinking of getting it at 1% and then their Value Premier Birch for blackout). I am also planning to go to their showroom next week to push the consultants there on non-toxic opti0ns but my sense is they don’t know much. I’m not sure if you have ever worked with or looked into Lutron Fabrics and if it’s too much research I totally understand you won’t be able to reply but if you do that would be amazing. Your time is valuable so I would also be open to setting up an appointment but I suspect your time is incredibly valuable and you probably no longer do appointments. But pls do let me know, happy to chat! All the very best!
Corinne says
You should get samples of their fabrics to see how you do. And if the blackout is vinyl that is high in VOCs.
Ann says
Hi Corinne!
Thank you for this wonderful post! I try to research best options when buying something new to maintain a low-tox lifestyle and I recently decided to get Pella doors based on my research. We went with a wood door with aluminum cladding. I thought I asked all the right questions as they were guaranteeing me that the stain was water-based, there was no California Prop 65 warning, etc. Then I read your blog and got worried about treated wood which I never even thought about. Pella uses an EnduraGaurd treatment on their wood. They couldn’t give me any other details than that though. I’m currently freaking out and not sure what to do. Do you know how toxic their EnduraGaurd treatment is and if I should try to go with another door or try to seal it? It will be in our playroom and I’m sure our little one will be touching it a lot so I want the safest possible option. Thanks in advance for your help!
Corinne says
I don’t know what that is. If they won’t share it I won’t know though you can ask for an sds sheet and sometimes you can find patents by the company.
Ann says
Hi Corinne!
I was able to get the SDS sheet and honestly, I don’t really know what I’m looking at. It looks scary to me but I don’t know how much of the product will actually get in the air or transfer from touch. I’m mostly concerned about my daughter putting her hands all over the doors and then into her moth because these doors are going in her playroom.
The products name are WOODLIFE® 111 HP with TIMBERTREAT® ICP-5 CUSTOM BLEND – (READY-TO-USE). I saw that you mention Timbertreat in this article. Do you have any other information about these products and have any advice if you would feel safe using these doors in your home? If there is a way to send you the full SDS, I could do that as well. Thank you SO much for your help with this!
Corinne says
I haven’t done a deep dive into those chemicals, all I know is that highly chemically sensitive people do often react to them, and that’s why I mention them.
Ann says
I really appreciate your reply’s! We decided to go with the Pella door option. They said there is a polyurethane sealant on the wood. Do you think that would be enough to seal in the pesticide/preservative treatment or should I put another sealer (one of the ones you recommended in this article) on top. I’m not sure if those can be used on already stained wood. Thank you!
Corinne says
a water based polyurethane is a pretty good seal of a lot of things
Sam says
I wish I would have seen this sooner! Our builder only uses Marvin Elevate black interior and exterior. Any ideas on how to make them less toxic?
Corinne says
It’s not necessarily toxic, not all fibreglass windows are. So it depends on if it’s offgassing and how sensitive you are to it. If it is offgassing and you are sensitive to it, see the post on new house offgassing. Start with heat, and ventilation and use a sealant like shellac as a last resort. You can layer paint and shellac to block offgassing if you need to. lots of info in other posts.
Sarah Webster says
Hi Corrine,
This is so impressive. Thank you for this blog. I’m currently looking at dual blinds for our nursery (sunshade and blockout). The material is called ‘Linesque’ and it’s 100% Polyester with Acrylic Coating and a Greenguard Gold certification. Is there anything I should be concerned about?
Violetta Sur says
Polyurethane canned foam for window sealing – my contractor was about to use some Russian brand I never even heard of. I’m in Canada. So now I’m trying to find something else. We did a test strip using Handi Foam and it just refused to stick to the frame. It did not hold up…literally. It was dripping and wouldn’t form. The window company wouldn’t recognize the warrantee if I went through with it because it was a disappointing fail. So I’m on the lookout for another foam. They all seem so very toxic. Ingredients such as propane, xylene, butane, mineral spirits, the list goes on. I have a 4 year old and really wanted to find something safe. My contractor is now recommending Hilti Foam, a German product. It still looks gross.
https://www.hilti.ca/c/CLS_CONSTRCUT_CHEM_7132/CLS_FOAMS_7132/r3476
My real question is, do all of these nasty foams cure completely……and when dried, is the off gassing of these dangerous chemicals really an issue, or once cured this is no longer a problem for the home dweller and her toddler? Please help!
Corinne says
it’s better to use backer rod + caulk. The foams have flame retardants that don’t offgas to completion. The VOCs do offgas though.
Violetta Sur says
Are they a risk when used in the window gaps? I know after that comes drywall and paint, and then any finishes, trim, caulking around windows. Does that also help in sealing off the remaining off gassing and flame retardants? I just have a feeling the window company installers won’t be open to options! Most aren’t and have a way of doing things for years, they aren’t really willing to do custom so I’m wondering what else I can do here. So frustrating.
Violetta Sur says
Replying to myself here as an update. My contractor said as an option, they can just stuff it with fibreglass batt insulation and then when there are some remaining gaps they can use a little bit of handifoam. I think that’s a much safer option with little chemicals and no fire retardants. I know handifoam is quite a green product and I’m using one of your recommended insulation batts (the certainteed). I called them the other day and they confirmed that they do not use any fire retardants in their insulation and it is greenguard gold certified). What are your thoughts on this option, Corinne?
Corinne says
No, don’t do that, it needs to be air tight. Handifoam has flame retardants as well, all the one part spray foams do. You can use that or baker rod and caulk.
Anna says
Thank you for your extremely helpful website. Roughly how long does it take for fiberglass to off-gas? I understand that it’s brand dependent (I’m looking at Milgard Ultra series), but a rough estimate would be so helpful.
Audrey says
Do you have an opinion on aluminum clad wood windows?

Josh H says
Hello Corinne and all- we are looking for non-toxic windows for our renovation. We contacted Loewen about their accoya windows and asked about toxic substances and this is what they sent to us with regard to toxic contents. Seems pretty toxic! Is there a less toxic/ non toxic alternative aluminum or accoya window out there?
Thanks for any tips or info from someone who has researched this. And thanks Corinne for all your energy helping us all out!

Note that Loewen has been the most forthcoming and transparent of any of the window companies we have approached. There are likely worse ingredients in other brands. But is this really as good as it gets toxin-wise?
Corinne says
each one has to be evaluated within the real context. I don’t have time to go through them all, but a lot of these are stain/finish options so you can choose one or go with a custom finish.
Carbon black is a risk only if you inhale that during application or you sand it and inhale/ingest it.
Phthalates are found in small vinyl parts and are found throughout the house in appliances etc
PVC cement offfgases quite fast so not really a risk to the final owner.
Etc etc
Josh H says
Yes you are correct Corinne- most of those chemicals are related to the finish, so if you go with accoya or an unfinished product they should not be an issue. Nevertheless, due to the high price of the Loewen Accoya windows, we are considering a good (non toxic) aluminum window if anyone has a recommendation of a brand that is durable and has good customer service.
Corinne says
I mention a few brands that are good
Sarah says
First: As always, AMAZING content! Thank you, Corrine, for so generously sharing your ongoing wealth of knowledge and experience!!!
Second: Windows: The window companies listed as top tier in terms of reputation may be so based on a certain type of window, but not all types. Some make great wood windows, but if they also make vinyl windows, they may not be so great compared to other companies that only make vinyl. So quick tip, carefully vet what kind of window you want and make sure that company has a good reputation for THAT kind of window.

Hello,
Could you please help me! I am having such a difficult time trying to find “short blackout” curtains for my 16 month who reached her crib’s height limit and needs to move to a toddler bed in a toddler room. I can not find “short” curtains that will cover only the area of the windows without reaching the floor that it will be a potential safety hazard. Hope you can help me Thanks

Hello, I think you might want to include Pottery Barn’s Blackout curtains too!
Mariane says
Hi Corinne,
Just found your website. My husband had a local shutter company that claimed their product is real basswood with white finish. He said it’s some sort of wherein williams finish. The product is made in China and finalized in the US. What are the concerns with this, if any? I can’t find much information online but hoping this is a decent option. They installed it today and I didn’t noticed a lot of smell, but I did notice the smell from the caulking from AFM safecoat if what we got. I’m just hoping this shutter doesn’t offgas much.
Corinne says
It sounds like it should be good.
Georgio says
Hi Corinne,
I’m Mariane’s husband and wanted to follow up with a little more info on this. The shutters are Onyx brand and according to the installer, there is a polyurethane coating on the base layer which is then painted over with the white paint. Sounds like a pretty standard practice. Hopefully still nothing to worry about? My wife is wanting to have them uninstalled now resulting in us losing almost $2k because of the simple fact of the polyurethane coating underneath the paint. Also, the AFM Safecoat seems to have a strong plastic type scent. The shutters were produced between 8-11 weeks ago so any issues with curing/offgassing should have since passed correct? The shutters themselves do not smell. Thank you for your time.
Dean says
Nice article! I’m contemplating Pella wood windows in my new home, However. I’m not overly keen with the treated wood. How effective is AFM Safe Seal for this? Are there test results available somewhere showing its effectiveness? Would a chemical free linseed oil work similarly in terms of sealing the nasty stuff in?
Corinne says
I believe they have done some little tests with SafeSeal and formaldehyde. Linseed oil is breathable and so it’s not used as a block. The less breathable the better seal usually.
Alyson says
Hi Corinne,
Thanks so much for this important work you’re doing! I’m an architect specializing in healthier building materials so am excited to be in touch. Do you have any experience with Mathews Brothers vinyl windows? Builders give great feedback on them, and I like the performance: cost ratio of the higher end Sanford Hills line, but am trying to stay away from specifying vinyl windows for environmental and human health reasons. However, for many projects, they do fit the bill, so I’m wondering if you have any intel specifically on Mathews Brothers vinyl formulations and outgassing potential compared to something like Fibrex. Thanks so much.
Corinne says
I would check to see if it’s unplasticized, that’s all I would need to know. There’s an environmental impact of vinyl but essentially no offgassing from unplasticized. Extremely sensitive clients are usually OK with it, some may want to seal it on the inside.
Alyson says
Thanks, Corinne. According to MB’s architectural rep, Mathews Brothers uses uPVC.
JJ says
Hello. Thank you for your insight. I recently moved into a new apartment with several southern facing large windows. I initially put up blackout fabric on the windows to keep it cooler and block out direct sun. The management didn’t like it and a week ago I moved the fabric to the inside, exposing the installed vertical vinyl blinds to the outside. Since then I’m dealing with extreme odors during the heat of the afternoons and constant headaches and nausea. Clearly these blinds are off-gassing under the heat from the sun. Can you recommend anything here? I’m going to remove the vinyl blinds tomorrow and put up the fabric again. But come Monday I’ll need to address this with the property manager. When I told her about my symptoms a few days ago, I asked if anyone else had this concern and she said no. Are people just unaware? I can’t knowingly breath these toxic fumes “until it wears off.” But I also don’t want to feel like I’m making a big deal out of nothing. Clearly these blinds are not high end and made for cheaper apartments. Which means the off gassing is likely toxic. She said “it will go away in 6 months to a year.” Really? Not a good answer. Anyway, any insight would be much appreciated.
Corinne says
Hard plastics that are offgassing can be sealed with shellac. Removed later with alcohol.
JJ says
Okay, Thank you. I will look into that. How concerning is this constant odor during the heat of the days? Do you think it will go away anytime soon? Or do I need to move forward right away to limit this?
JJ says
..And do you think that shellac would be okay in higher heat? Not going to damage the blinds or change its appearance? Thank you again,
Lucy M McKernan says
Excellent resource to which I’ve referred a number of times. We had our GLASS ONLY replaced this year in a very large sunroom window, after much research and consideration whether to install entirely new window with frame, or not. We purchased the AFM Safecoat caulking, and the company who installed the glass did a great job. Please, anyone reading this, consider also the dwindling number of birds with whom we share the planet, and install an ENTIRE GLASS collision protection system. We’ve experimented with a number of window collision techniques, and the most effective which prevents strikes in CollidEscape, but it’s made from PVC film, However, it’s on the outside of the glass, so it probably offgases quicker. The other, which the glass installers were kind enough to hang for me, are Acopian Bird Savers, a simple application of weather-resisant, almost full-length strings spaced the right distance from each other. We’ve heard the dreaded “thumps” and seen the dead or injured birds, so please consider others when installing new windows.
Corinne says
Thanks for sharing this Lucy
Marie says
Thank you for the in-depth article. Should have read it before purchasing new thermal roller blinds from mrblinds.co.nz for our bedrooms which apparently have a foam acrylic backing. They are OekoTex 100 certified but unfortunately have an unexpected offgassing-type smell (newly put up). Is it safe to keep the blinds if the smell goes away in a few days or will there always be a risk associated?
Bonnie says
I have blue fabric curtains with foam backing from JCP. They are about 10 years old. Do they likely have flame retardants? Is the foam worse. Thank you.
Amy says
Hi Corinne,
I am planning to make a some simple fabric curtains to block the sun, both for keeping cool (we found mold in mini-splits) and room darkening. I held up a scrap of velvet and it blocks all the light. So, I want to buy velvet for the front and a lightweight white fabric to back them (reflect sun). Any recommendations that would be healthy for bedrooms (breathing that air all night) and hopefully not degrade too quickly from all the sun exposure (it’s going to be a lot of work and I’d hate to have them start falling apart in a couple years). Thanks so much!
Jay says
I installed several Allen & Roth blackout cellular shades from Lowe’s a couple months ago. They are made with recycled polyester, and promoted as good for the environment. because they keep plastic bottles out of landfills. Even after 2 months, I can still smell them off-gassing. They smell like stale cigarette smoke to me. (No one has ever smoked in my home.) I like many aspects of the shades, including reasonable price, but despise the persistent smell. Do you have experience with these shades? Will they ever stop off-gassing?
Corinne says
is it the polyester cellular part that smells or the vinyl bits?
Aimee Wineland says
We recently received a quote for some Marvin Infinity Windows. They were very expensive IMO but the man said they won’t off gas because we brought it up because of not wanting vinyl windows. I read a comment above about aluminum. Do aluminum windows have keep the cold out during the winter and the warm out in the summer? We want to be as safe as possible, especially for our kids health.
Corinne says
Thermally broken aluminum windows have insulation in the middle.
Aaron says
Question about Shade Store solars. For their basic 1% solars, they state:
1% / White
Composition :
35% Fiberglass / 65% Vinyl
Description:
Blocks 99% of harmful UV rays and preserves your view. Protects by interiors. GREENGUARD® & Microban® certified. Eco-friendly
Is this greenwash nonsense? How can a fiberglass/vinyl shade possibly be “eco-friendly”?.
Amy says
Hello, I’m looking to get shutters in my house and came across the Eclipse Shutters from Blinds Chalet. According to their website these particular ones are Greenguard certified… do you know anything about these? They are still made from vinyl/polyresin which makes me a bit nervous. Would love to hear your thoughts! Thanks so much for all you do!
Blinds Downunder says
Hi Corrine,
Thanks for posting such a fascinating article regarding Non-Toxic Windows, Blinds & Curtains. Our first house we lived in had curtains which offed high Voc gasses, we always woke of a morning congested and groggy and didn’t know the cause, until I completed a short course in building sustainable green homes.
We now have an online window furnishings business in Australia and have done a lot of research around low Voc options to create healthier internal environments. We have a large amount of products which have been Greenguard Certified. If you don’t mind we would love to link your article to to help explain the benefits of choosing the right window furnishing materials . Our web address is http://www.blindsdownunder.com.au we have a few areas which touch on these details in fabric specifications, a couple of content pages and on our samples page. Your article would really help us confirm the importance of smart material choices within your home for healthier living.
We are so happy we have found my chemical free house today.
Thanks for the great read
Dorothy says
Marvin claims their ultrex fiberglass has no VOC’s and does not off gas. I just had them installed on the south side of my home and am bothered by something. There is some ABS plastic on the windows. Is Marvin lying about the fiberglass not off gassing? Can you have an aluminum window where summers are hot and winters are cold? Is the fiberglass better for the environment overall than the polyurethane inside the thermal improved aluminum windows? Thank you.
Corinne says
Fiberglass offgasses, ABS doesn’t or I haven’t been able to pick that up. Aluminum can be fully thermally broken for cold and hot climates yes.
jennifer says
I’m so thankful for your site. As a first time homeowner I refer to it so often! Our next project is impact windows. We live in SFL and the options seem to be regular aluminum and vinyl. I haven’t found any thermally broken aluminum windows being offered yet. I do know of moisture issues with regular aluminum frame. I feel this is still probably safer/better than vinyl? Pgt aluminum is what we were going with. I’m going to ask the installer about caulking next!
Corinne says
In South FL you may not need the thermal break.
Jen says
In that case would you go with aluminium over vinyl? Vinyl has a longer warranty and better energy ratings. I’m just trying to avoid it but don’t want to do so if there’s no good reason.
Suzette says

For a baby’s room I’m looking for blackout type coverings.
I came across that you mention :
“ Blinds Chalet blackout liner on the bamboo shades is PVC- free.
Their bamboo is also grown without pesticides and chemicals”
Can you give a more specific name or sku for the product listing…or the URL. I went to the blinds chalet website and there are so many options I was overwhelmed. I want to make sure I get whatever non-toxic option you are mentioning in this post.
Corinne says
I link to it in the post.

Hi Corinne,
Would love to know your opinion on roller shades that are half acrylic, half polyester as well as rollers that are 100% poly with acrylic foam backing. I don’t know much about acrylic and its potential off-gassing. Thanks! 🙂
Corinne says
I would need to get samples to know. Can you post some links I will get samples.
Niki says
They are all coming from Hunter Douglas – room darkening/privacy opaque roller shade fabrics (in neutrals/creams). [Let me know if you were wanting the specific fabric choices/colours I was considering] 🙂
Thanks so much for your time! 🙂 Happy New Year!!
Niki says
I’m concerned about the potential off gassing I might have every summer when they bake in the sun!
Corinne says
Post links to samples if you like.
Niki says
Hey Corinne!
A couple options I have been considering are:
Hunter Douglas:
SHADOW 0% ‘Flurry’ Deck 6 Style 5 SDW-10103
(100% Polyester with Acrylic Foam Backing)
&
UMBRIA 1% ‘Quartz’ Deck 5 Style 11 UMB1-140
(37% Fiberglass, 63% Vinyl on Fiberglass)
Apparently all Hunter Douglas products are Greenguard Certified, but what does that really mean? I know there are different levels to that certification.
Thanks so much for your time. Appreciate you looking into them! 🙂

I had a lengthy discussion with Hunter Douglas some time ago as I have their roller shades and I’m super picky about materials and chemicals, even though I’m not really chemically sensitive.
They told me, and confirmed via email, that they do not use any of the following on their polyester / acrylic blend (called AGORA) is a commercial fabric that is Greenguard GOLD certified, has no PVC, no formaldehyde, no fire retardant chemicals, is not manufactured with any PFAS/PFCs, and no mico/biocides.
I hope this is consistent with what everyone else has been hearing from Hunter Douglas?
Hanne says
Could you please include EMF protective windows, materials,etc?
Corinne says
EMFs is not a topic I have enough expertise in.
A says
Faraday cloth?

Thanks so much for this article! I had a question about acrylic roller shades. I was going with Hunter Douglas 100% polyester rollers (to replace our curtains which just aren’t working out), until i got the quote that is not in or price range. The alternative option is a half acrylic, half polyester blend OR 100% polyester with acrylic foam backing. I can’t find a lot of research on vocs with acrylic. Apparently all Hunter Douglas is Greenguard certified and free from fire retardants so i don’t know if i need to be concerned. They are going in a spot that get a lot of sun. I’d love your insight! Thanks so much!

Dear Corrinne, thank you for your useful insight! I would like to get roller blind and there are a few fabric options, which do you think is the safer option, polyester or non-woven? Really appreciate if you could offer your thought on this, thank you! 🙂
Corinne says
Nonwoven could mean a number of fabric types.
Irina G Rosenblum says
Thank you Corinne for a very informative post. Do you have a recommendation for Window framing? My contractor wants to use Azak which is a PVC product for framing and I’m concerned about the off-gassing. Would very much appreciate your thoughts on this!
Thank you,
Irina
Corinne says
Both PVC and fiberglass have some offgassing. If you are sensitive I would check them out in person first.
Crystal Bryshun says
Dear Corinne,
I am currently building a non toxic tiny house, I have framed it and am getting ready to install home made wood windows, made from pine and Doug fur. I am trying to figure out what to use to protect the inside of my window. It has to stand up to lots of U.V. and moisture, when in the winter the moisture from the inside gathers on the corners of the windows, and sometimes even freezes, and melts onto the sill I was thinking of using hemp oil or something but I am thinking the oil discolors when water touches it.. I am very sensitive to, it seems mostly unnatural products. even after years of off gassing i can pick up stuff when the hot sun hits it… With that being said I need something that wont off gas on the exterior of my windows as well, because my windows are openers
I had trouble even with the plastic vapor barrier. I left it for many months and still it made me sick to go in house after vapor barrier was installed. I am currently going to give and aluminum foil vapor barrier a go… they recommend them for saunas.. thank you for your fantastic website and sharing your knowledge!
Crystal
Corinne says
The windows should be made so that they dont have condensation. I do like hemp oil a lot because I was too sensitive to tolerate linseed and tung when I built and probably still wouldn’t use those. Once the drying oils cure they dont discolor with water. Though they are not as durable as something synthetic. The post on finishes has more info!
Crystal Bryshun says
Ok, so did you say you used hemp on your floor as well? how did that hold up to spills etc? Its not the windows fault of condensation, its very cold outside climates with high moisture level inside. However, i will manage indoor moisture as much as i can through ventallation, air exchange and dry heat from woodstove… there is still always a little bit that can form on windows esp when temps are real cold
Sharon says
Hi there, I wonder if you might have a recommendation for cleaner external trim? A new house we just purchased has rotting wood in the external trim and we replaced the windows and would like to replace the external trim as well, and avoid wood for this reason. Our contractor recommended Azek exterior trim with is PVC (less concerning since this is the outside of the house), but from what I can tell, they also treat with chemicals including flame retardants which may get into our drip line when it rains. Any recommendations in this regard? Thanks so much!
Corinne says
There will be more options in the post on siding.
Janet says
I am looking for a non toxic sheer curtain. 99% are all 100% polyester. Are they all toxic?
Corinne says
Polyester always has (as far as I have seen) some chemical treatment on the fabric. I think it’s acceptable once it’s been either washed or aired out.
Margie says
The linen draperies featured in this article are not 100% linen. They are machine washable which linen is not. I ordered them and they are polyester.
Corinne says
ah the ones in the photo yes. I don’t mention them in the post but I will add that the photo is not 100% linen or else see if I can find a photo of real linen.
Chelsea Kissiah says
Hi. Would a Cotton curtain with polyester backing for blackout be acceptable Instead of a curtain that is 100% polyester? I found some on pottery barn that are cotton canvas with 100% polyester backing.
I’m thinking of not having shades for my children’s room and just doing safer blackout curtains. Your Input would help so much!
Thanks!
Corinne says
I think in terms of offgassing that will be fine. I would see if you can get a statement on flame retardants out of any big company you want to buy from. Vinyl backing is certainly the worst offender for offgassing and the main one I would avoid for black out
Corinne says
These are the windows I used http://www.dygwindows.com/aluminium-windows/
Unknown says
Which aluminum window manufacturer did you use? I'm looking for double hungs Milgard only makes singlehung there's Crystal in NY but they don't have flange type in DH availble at present.
Unknown says
Hello, decent article.
1. "Avoid vinyl mini-blinds" why not?
2. Why people keep stating that you recommend "offgas aluminum blinds" as I understand offgas is a bad thing, isn't it? meaning blinds will give off a chemical, especially a harmful one, in the form of a gas.
thanks
Corinne says
They do offgas – emit VOCs, but you might be able to offgas them, as in let them fully offgas.
Vinyl is a much stronger odour and chemical.
Kelly and Kurt says
Hi, Do most shades contain flame retardant? I've been removing those cellular shades from my house because I assumed they did?
many thanks,
Kelly
Corinne says
Probably do. What are they made out of? You could ask the company if you know where they are from if they are compliant with flame resistant standards. Many polyester items have flame retardants on them.
Unknown says
It's also a good option to buy curtains , sheets or material at the thrift store or second hand else where to make your own black out window shades. I have fibromyalgia and bad chemical sensitivity so I use a lot of second hand materials.
Corinne says
That can work for some, I would not be able to use second-hand Fabrics to to contamination.
Unknown says
Hello. You speak about aluminum for windows being a safe option…but what about the aluminum blinds? Are they a safe option?
Unknown says
Hi there I bought 100% poliester blackout curtains for my baby room. And I am wondering how safe they could be in the nursery. They have very distinct smell and I afraid to put them in the nursery since they will be above the heat vent. Do you think they might start to spread toxins in the room?
Thomas Venney says
Thanks

Corinne: Thank you for your answer to my question re thermal breaks and condensation! I'm having trouble finding local aluminum windows that are also relatively energy efficient. So, I'm wondering if you think SCS Global Services Indoor Advantage Gold windows from Andersen (https://www.scscertified.com/products/cert_pdfs/AndersenCorporation_2017_SCS-IAQ-01638_s.pdf) are safe for 1) the chemically sensitive, and 2) reducing mold risk. The ones I'm looking at are 100 series (made of Fibrex) and A series (solid wood core, outside covered in fibrex, inside covered with your choice of stain, paint, or smooth vinyl type finish. Andersen assures me that the windows still meet the Indoor Advantage Gold certification, even when they have one of these indoor finishes: pain, stain, vinyl type coating). Can also leave bare wood on inside, paint oneself). I'm about to make a decision on replacing all windows in my house, and would greatly appreciate your input. Thank you again
for this amazing site!! (I will be doing all my Amazon shopping using your link!)
Unknown says
Thank you for your excellent website! You recommend aluminum or steel windows. However, there is a lot of info out there about condensation gathering on metal (due to the way it conducts the cold from outside, which produces condensation when it meets the warm inside air). And…where there is condensation, there is often mold or mold potential. (The mold seems to grow on any wood, drywall, etc. that the water drips onto–not, obviously, on the metal itself). Any suggestions to avoid this? Thanks!
Corinne says
The ones for houses (not RVs) contain a thermal break. I did not have condensation on mine.
Jason says
I see that you recommend "between the glass" window coverings and link to the Pella Designer Series wood windows. How do you feel about the windows themselves?
Corinne says
They have wood, fiberglass and vinyl, the same precautions would apply as mentioned in the post. I have not tested this brand. It was more an example of between the glass window coverings.
Tory Field says
Hi Corinne!
You mention using aluminum windows with baked on enamel finish. I'm wondering where you found those? I've been calling around and having a hard time finding a place to source all aluminum windows….
Thanks so much,
Tory
Corinne says
Yes, I have heard they can be hard to source. I got mine in Vancouver, Canada.
Unknown says
Thank you for this useful information! Could you please share where in Vancouver you found your aluminum windows, or the manufacturer? I have been able to find powder coated, but not baked enamel.
Thank you! Hannah

Hi there! I loved this article. I recently emailed a manufacturer to ask about my blackout shades and got this response: The Sound Asleep™ Blackout Window Curtain Liner does NOT contain any PVC/vinyl, phthalates, BPA, lead or flame retardants. It is made of 100% Polyester with a foam lining which is polypropylene acid ester/titanium oxide."
Based on that, do you think the product is still toxic… and should be replaced? I'm thinking of getting an Earthshade product but wanted to ask your thoughts. Thanks!
Corinne says
This sounds generally non-toxic, however I am wondering if the polyester is glued to the plastic. For the extremely sensitive the plastic will also have a smell. I would judge this product based on how it smells to you.
manyfires says
Thanks so much! In general, neither my son nor I seem sensitive to the material, but I'm working on phasing out toxins in the home and wanted to be thorough. I think our solution will be to get an Earthshade roller (on rails – so it blocks out as much light as possible) and keep the darkout curtains to pull around the edges.
Tara B says
Did you ever buy from Earthshade? Were you happy? I’m interested but cannot find any reviews or their business on BBB. Thanks,
A says
Also interested
I’m undecided between Earthshade vs Blinds Chalet….

Hello! What do you recommend for renters? Should we run the risk of being billed by installing entirely different window coverings altogether? I want to do so much to change what my little one's are exposed to. I'm just unsure how to go about it as I do not own my home and it use to be military housing so lead paint was used in my home, though sealed. I appreciate any recommendations you have to offer! Thanks!
Corinne says
Can you talk to them about what you would be allowed to do? The paper ones would be easy to take down. Or can you swap out curtains and put the old ones back?

My Cotton twill slip cover from Pottery Barn and I made 100% linen hobbled roman shades for 5 windows. I made a mistake and purchase 100 % cotton drapes they had an odor I washed and Iron them the odor was still there . I made a mistake and put them up in my spare room that I do not go into that often. The odor has traveled all over the house it is on my Linen curtains, sofa. bedding, clothing anything porous. My house smells so strong and my allergies are so bad. I have to throw everything away. I thought I would share my story .I will never put anything in my home that has an odor again. I hope this story might help someone so they do not have to go through this experience I am going through

Where do you find Aluminum windows with the baked on enamel? What brand name?
CT says
Don Young windows in San Antonio TX manufactures one of the nicest aluminum windows I have seen. The website is a little dated. Also, Milgard I believe has a nice baked on enamel finish aluminum window.
