Updated Summer 2021
1. Window frame materials – Windows made of thermally broken aluminum are the top choice for non-toxic windows. Accoya wood is also a healthy window option. Some vinyl and fiberglass brands can be considered, though they do offgas.
2. Window treatments – Natural untreated fabric, natural fiber roll-down blinds, non-painted aluminum blinds, and aluminum screens are the top choices for healthy window treatments. Blackout bamboo shades, polyester curtains, hemp, cotton, and paper pleated shades should be considered as well. Avoid PVC shades/curtains, flame retardant treated fabrics, wrinkle-free finishes, and wood and aluminum blinds with finishes that offgas.
3. Window sealing – Polyurethane canned foam is the norm, which does cure quite well. The least toxic option is backer rod.

Non-Toxic Curtains and Blinds
The best non-toxic window coverings are natural untreated fabric, natural fiber roll-down blinds, aluminum blinds and aluminum screens.
For blackout shades, bamboo shades with liners, polyester curtains, hemp, cotton, and paper pleated shades can be considered.
Avoid PVC shades/curtains, curtains highly treated with flame retardants and other chemicals, and wood and aluminum blinds with finishes that offgas VOCs.
1. 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 or GOTs certified fabrics to guarantee that they don’t use chemical treatments.
Libeco linen is not GOTS certified but is usually grown without pesticides and the natural colors don’t contain dyes.
Linen options found on Amazon, like the ones in the photo, are either a linen polyester mix or polyester made to look like linen.
IKEA makes GUNRID “air purifying curtains”. These are made of recycled PET water bottles. The air purifying claim sounds like it comes from a treatment of titanium dioxide which creates hydroxyl radicals.
2. Blinds and Shutters
Bamboo Blinds
Green versions of blinds include bamboo roll-down blinds that are not treated with chemicals like those from Earthshade and Blinds Chalet.
I got a sample from Blinds Chalet and was happy with them (these really need a backing unless you want just minimal privacy).
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.
Wood Blinds and Shutters
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.
The real wood blinds from Blinds Chalet are very light and thin (Signature 2 inch in Carmelia). I could pick up only very minor offgassing which did come to completion in a few weeks.
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 this up. And with a bit of time, this did offgas.
Real wood blinds made of basswood are extremely light. From an aesthetic point of view, they are almost impossible to differentiate from the composites.
Faux Wood
Faux wood blinds are usually PVC, but composite blinds can be made of safer plastics mixed with wood.
The composite sample I got from Blinds Chalet was very low in offgassing (Premier Composite Shutters).
Composite blinds from Blinds Galore 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 use powder-coated metal 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.
By the time I have received samples of metals blinds the offgassing has been complete.
I have also seen additives, for example, Hunter Douglas ads an anti-static additive to the coating. This may be something like Teflon (but we don’t actually know what it is), which could offgas as well.
You can find brushed aluminum blinds with no paint or coating, like those from Earthshade (pictured). At some retailers, brushed aluminum does have a coating.
3. Between the Glass Blinds
Between the glass is a really cool option that eliminates the worry of offgassing.
Here is an example from Pella.
4. Window Screens
Conventional screens are very smelly at first.
They can be left outside to offgas, or aluminum screens can be used instead.
Marvin is one brand that makes aluminum options.
Non-Toxic Blackout Shades
1. Bamboo Shades Blackout Liner
Blinds Chalet blackout liner on the bamboo shades is PVC- free.
Their bamboo is also grown without pesticides and chemicals.
2. Polyester Blackout Curtains
Polyester with no PVC backing will work for many 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.
West Elm 100% polyester curtain liner is an extra layer of polyester that goes under their other curtains, they = contain no PVC or foam.
They 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.
These Eclipse polyester curtains from Amazon do not contain flame retardants, can be washed and aired out, and should be tolerable after washing and airing for most people.
Sleep Well company that makes polyester curtains does not guarantee no flame retardants, but they do claim no chemical fabric coatings. They are 100% polyester and free of PVC. They are washable. You can remove that new fabric smell by washing them. Some have reported these having no smell and others more sensitive still can pick up the new fabric smell.
3. 100% Blackout Shades
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 ppb formaldehyde which is produced when pressing the polyester sheets together to laminate them with heat.
The shades have also been processed with bleach. Those are the only two treatments of the fabric.
Generally, my recommendation on formaldehyde (as long as it’s not urea) is to give it 3 months of offgassing. When installed with a proper blackout system these will get you the most light blocking of the list.
4. Something Simple for Light Blocking
Another option to consider is this paper black pleated shade – 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.
5. DIY Hemp Curtains
Another really safe option (truly the safest) would be to make your own blackout curtains with pesticide-free hemp fabric.
Though it’s difficult to make traditional looking curtains from this thick not very flexible fabric.
6. Cotton Room Darkening Curtains
IKEA Room Darkening Curtains made with 100% cotton are somewhat light-blocking.
They should be washed or aired out before using.
Avoid: vinyl roller shades and vinyl mini-blinds, PVC, and conventional blackout curtains.
Non-Toxic Window Frame Options
The top choice for green non-toxic window frames is aluminum (thermally broken).
Accoya naturally treated wood can be considered another top choice, though wood is more difficult to upkeep.
Fiberglass and vinyl are the next best choices – they do offgas, but some brands will cure quite quickly or be low enough emissions to not cause any issues.
Non-Accoya wood is treated with pesticides, insecticides, and fungicides and it’s prone to warping and water damage. Let’s look deeper:
1. Metal Window Frames
Aluminum windows are the healthiest, safest option. It is what I used in my tiny house (pictured above). On the interior, I added wood framing trim. You can also use decorative moldings around the windows.
I used DYG windows from Canada. Milgard is a popular brand that makes thermally broken all aluminum windows (US and Canada).
High-end aluminum thermally broken window brands include Western, Arcadia, and Fleetwood.
What is used in the windows as a thermal break is blocked by the glass and metal so there is no need to worry about much offgassing. Thermally broken aluminum windows are all aluminum with polyurethane inside.
Non thermally broken aluminum windows are not a good idea to use as they conduct heat and cold and easily condensate. Aluminum clad means there is an exterior of aluminum which usually has wood inside.
The most extremely sensitive clients can pick up the seal, PVC glass stop and some glues used.
The finishes I have seen on aluminum windows are baked-on enamel, resin paints, powder coated, and anodized. Some baked-on enamel finishes and paints can offgas, the other two are considered safe.
The gaskets are made out of rubber or PVC.
2. Wooden Window Frames
Wood windows are usually treated with fungicides, pesticides, and insecticides. You could use a sealer that seals those chemicals like AFM Safe Seal, AFM Transitional Primer, or Zinsser Shellac (the Bullseye Shellac is waxed and harder to paint over, the SealCoat is dewaxed and easier to paint over).
Safer Wood
Accoya wood used in some window brands uses a non-toxic process called acetylation to naturally provide rot resistance.
They use no chemical fungicides or mildewcides and they claim this process helps to reduce shrinking and swelling compared to most solid wood windows.
Loewen is one of the brands that uses Accoya wood and allows you to choose your paint brand.
Custom Wood
You could go with totally custom-made wood windows, but they are more expensive and you still have to consider what kind of sealer you can tolerate on the inside and outside.
For an exterior sealer see my post on paints and sealers.
Problems with Wooden Windows
All wood (through and through) windows are not a good idea as they do not hold up well to moisture in the long run, Accoya wood claims to have solved this problem.
You can also consider ones that are wood on the inside and a more weather-resistant material on the outside if you like the look of wood inside.
Consider also the glue that is used in conventional wood windows could be irritating for the sensitive person.
Chemical Wood Treatments
Marvin’s wood windows (which have aluminum on the exterior) are treated with TimberTreat pesticide, tebuconazole, and propiconazole fungicides, an unlisted insecticide, and mineral oil.
Pella and Anderson also make wood windows that are treated with the same or similar chemicals (they are also aluminum on the exterior).
3. Fiberglass Window Frames
Fiberglass offgasses VOCs and some sensitive people do report reacting to it. Though it may be tolerable for some.
Some types and brands are better than others (in terms of offgassing) and this could result in a preference of fiberglass over vinyl or vice versa.
Marvin’s Ultrex was not tolerated by the very sensitive though some less sensitive have done well with it.
Marvin has two different kinds of fiberglass, one has an acrylic component and one has a polyurethane component. You may find them to be different – with the polyurethane one being better tolerated. Pella fiberglass is tolerated by some sensitive folks.
Kolbe has their own fiberglass called Glastra which is mixed with another polymer (plastic).
4. Vinyl Window Frames
Vinyl is generally not healthy, but since this is a hard usually unplasticized vinyl, it does not have much of an odor at all. I did not pick up any offgassing on the vinyl windows I tested (and used in a little camping trailer). uPVC indicates vinyl without plasticizers, which is the most harmful part of the vinyl.
I can pick up the offgassing in some of them used in apartments under one year old. Others have reported reacting with new ones. Some let them offgas for a while before installing.
Personally, with a bit of time to offgas, I find these to be good. Better than fiberglass, but not as good as aluminum.
Fibrex is a PVC and wood composite made by Anderson which some sensitive folks have reported being too high in offgassing for them.
Tyrol is a fiberglass reinforced uPVC with EPS foam in the interior by Alpen.
Vinyl Components
Vinyl components can be used in any window frame type. Look into the gasket, window stops, jamb liners, and tracks which can all be PVC. I have seen some companies (like Alpen) replace the PVC stop with aluminum.
More details on Alpen (which makes fiberglass and vinyl windows) and other low-toxin “High Performance” windows in this post on Passive Houses.
Window FAQs
What are High-Quality Trusted Window Brands?
High-quality window companies recommended by architects include: Marvin, Kolbe, Anderson, Pella, and Wasco. Alpen for High-Performance windows.
Are Gas-filled Windows Non-Toxic?
Windows filled with argon or krypton gas have a higher insulative value and both gasses are considered non-toxic.
Are Low-E Coatings Non-Toxic?
The two main types of Low-E coatings are both non-toxic. The “soft coat” is a mechanically applied silver coating that is within a double pane window system. You will have no exposure to the silver. A “hard coat” is a layer of tin oxide that is applied while the glass is still hot. The tin is a more integral part of the glass in this case, and is therefore not a risk.
Sealing Around Windows
Caulking
The first two I would test out are AFM Caulk and silicone. Silicone caulks all have different odors/offgassing and rates of curing. My top pick is a neutral cure silicone – Chemlink. GE is also quite good.
I have a post on caulking that goes into more detail.
Sealing the Rough Opening
Plastic backer rod (polyethylene) can be used to seal around windows. This is a non-toxic and odorless alternative to polyurethane canned spray foam.
Many people do tolerate the canned spray foams after some offgassing (give it 24 hours to cure or more). Great Stuff is a common one to find easily online and in stores.
Handi-Foam is another brand, that is certified with Greenguard Gold for more assurance (but I cannot tell the difference between the two).
Some people use wool around windows. I prefer not to have wool around windows. The sealing around windows is meant to be airtight to prevent moisture issues, so wool would not suffice.
Window Flashing
For zero-VOC window flashing use TYPAR AT.
They do not recommend this being used in the rough openings, and it doesn’t fit all building codes.

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
Hi Corinne,
Are there any safe, non-off gassing shutters in the market? Hunter Douglas sells polysatin shutters. Do you know anything about polysatins?

Amy Williamson 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.
Bridge Dale says
These window coverings will make my house look better, and I’ll try to purchase these coverings as soon as possible. The only problem is that I don’t have enough money to buy these coverings right now.
Niki says
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! 🙂
Niki says
One other one I forgot to add:
https://www.hunterdouglas.com/fabrics-materials/skyline-collections
AGORA 0% in ‘Colosseum’
(44% Acrylic 56% Polyester)
Thanks again! xx
Hanne says
Could you please include EMF protective windows, materials,etc?
Corinne says
EMFs is not a topic I have enough expertise in.

Faraday cloth?
Niki says
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!
Char says
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.

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.

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.

Did you ever buy from Earthshade? Were you happy? I’m interested but cannot find any reviews or their business on BBB. Thanks,

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.
