How to Seal a Whole House with Foil

My last post was about The Many Varied and Delightful Uses for Foil. One of the listicle points was about sealing the floor and fittings with aluminium foil to make the place liveable. For example: The sea-side rental property I live in has foil over the floors in every useable room. The two bedrooms that I can’t use, due to fragrance chemical residue in one of them and a brand new wall-unit of chipboard cupboards in the other, have both room’s doors sealed shut with painter’s masking tape and massive sheets of foil to stop any fumes outgassing into my sleeping area.


It’s not exactly Home Vouge, now is it?

My sleeping area is in the open-plan-lounge-kitchen-dining area, which besides the bathroom, is the only room I can be in without getting very sick. Also in this area: there’s my home gym (treadmill, weight bench, yoga mat and pilates ropes), my cane dining table, kitchen, my bed and my dog’s bed, my wardrobes and my home office. It’s pretty crowded in here. Most days I try to feel grateful that I have a safe-ish home to live in. Many days, lately, when I’m not sick, I’m blissfully happy in my little cottage by the sea. I know of many people who have to sleep outside in tents, caravans and on balconies, or in homes that are totally unsuited to people who’re sensitive to chemicals. Plus there is another room where I store all my boxes of stuff; that room has foil on the floors also.


So yeah, I’m lucky I have this rental property to stay in while we build an actual safe home; however, there are other days where I’m not sure how to cope with getting so damn sick. Sick from foods, sure, I can cope with that because I have an element of control over what I eat, but getting chronically ill from neighbours and their woodsmoke, the outdoor moulds and, inside, a lack of ventilation because I can’t open the house and air it as often as I need to, is hard to cope with. The floors still outgass terpenes from the pine boards; but worse than the pine fumes are the lemon-scented cleaning chemical fumes that emit when the house heats up or is closed for too long a time. I need to be able to air my home everyday. During spring and summer, I can have the house open most days, only going into lockdown on weekends when our seaside town is overrun by terrorists tourists, BBQs, lawnmowers, backyard burns (illegal but people still do it) and nearby smoke from bushfires and burn offs.

If my neighbours hang their washing out, or wash their concrete with disinfectant (yeah, in the ‘interest’ of young children, that’s what they do.) or they mow lawns without sending me a warning text (one neighbour finds it just too inconvenient to help me), and my windows are open, I get horribly ill. So I only open my windows when I can stay vigilant about the state of the outside air.

On many days, my house is kept dark with the blinds pulled down to keep it from outgassing. To be comfortable, breathing wise, I need the air-conditioner to be running if the sun is out. But for now, as it’s so damn cold, I choose to sit here cloistered in darkness. Yeah, that impacts on my mental and emotional well-being; not to mention my mood. Consequently, I don’t feel very positive when I have to live like that.

Things will change for me when I’m in a safe house; I know that. But for now, the soundtrack to my life is the hum of an InovaAir filter and a AusClimate dehumidifier working to control my indoor air environment; and the best chance I can give my health has been to try and put a halt to the chemicals that outgass in this house. Enter my trusty rolls of foil!


Thankfully, there are some things that are within my control:

There are six layers of foil on the floor of my living space. At first we only had three layers but as time has wound on and I’ve been living here since 2013, nearly three years now while attempting to start our build, we’ve had to add extra layers because of the top layer getting ripped by my dog, Bella, my furniture, our foot traffic and the wheels on my air purifier as I move it around to clean the air. Pain in the arse, yes, but this foil trick works. (We wear socks a lot in here.)

I’ve used foil for many things, as most of my readers already know, but sealing a whole house has been a challenge. I hear some of you ask: well. why live in a property that’s not suitable; one that impacts on your health?  The answer to that is: I spent eighteen months looking for a rental property near the Surf Coast of Victoria where we are going to build, and most properties where totally unsuitable and I didn’t even venture past the front door because of the cleaners/moulds/fragrances/paints that were in them. This property is pretty good—when other people are not destroying the outdoor air—when I can keep the house open for a few hours a day. It looks a bit weird, having all this foil on the floors; and my teenage daughter was mortified when she lived here for a while. However, if you can breathe without being in pain, the space-ship, futuristic silver look takes on an attractive sheen! Trust me on that…

So this is how, and what we did to seal a whole house with foil:

First, we told the real estate agent we were doing it; and we had to agree to pay for any damage that this might cause (it won’t. Just wait until you see our technique!);

I had to source the foil. In another article on How to Seal a Room with Foil we used Kingspan Insulbreak, which is a vapour barrier and a thermal break used to insulate and wrap buildings in. It’s about $300 a roll and pretty expensive for this type of job. All the other foils that I found either had paint on one side (builder’s foil) or had a fire retardant blanket attached to it. I managed to contact a company that makes the fire-retardent coated foil and bought some rolls of foil before they were glued to the blanket. So what I have here is just foil.

There are two types: Foil coated brown paper, which the guy at the fire-retardant place gave me for free; and the roll of heavy-duty foil, which cost me $400. Cash. We used the brown paper foil to protect the floorboards underneath. In my experience, aluminium foil can rub of a silver stain onto areas; especially if friction is applied. Also it can flake off. I wasn’t sure if this would happen so I used layered the brown paper side down over the floorboards to protect them (and my bond money!).


And for some jobs we actually used kitchen foil:


This gas heater was a mahoosive problem, and it was one of the first areas we sealed. Not only were the previous tenants smokers but they also burned a heap of nasty smelling incense (it smells like cat pee, I swear). For some reason most of the scents were emanating from here so I covered and sealed it straight up. I don’t muck around. It’s not like I’d want to try and clean stuff like that off; and I’ve lived with this condition long enough to know: you can’t scrub off fragrance because it’s designed to stick around. This job completely used a few small rolls of kitchen aluminium foil, which I then sealed with heavy duty aluminium foil tape.

For the first layer of floor’s foil we used heavy-duty foil tape to seal the edges. But for around the edges of the room we chose painter’s masking tape so that we didn’t damage the skirting boards. Any area of the house where foil is stuck down with tape adhering to surfaces, such as wood or paint, we’ve made sure that it’s only painter’s tape that’s stuck down to it. This way it will not leave any gummy, sticky residue there. (Someone pointed out that if there is gunky glue left over when it’s time to move out, I could clean it off using some olive oil and a hair dryer. Clever, I know!)


Another layer of foil just added

Each time it gets ripped [I’m looking at my Boxer Dog!] we have to put a piece of tape over the rip. It looks ugly after a while; and it’s not exactly clean because I can’t wash the floor like I could if it were tile or boards, so we have to replace it. Also, during hot weather, the fragrance and solvents used in the residues from previously used cleaners come through the foil, so again, this needs replacing. Do we do that though? No, we just vacuum then put another couple of layers over the top. Kind of like floor lasagne.


Before the Latest Layer of Foil. A little gross, I know!


The Edges are Joined with Tape

Vacuuming can be a challenge. Not that I can vacuum myself because dust gets stirred up giving me a headache, and it’s painful to breathe for a couple of hours or until the next day. So when it’s time to vacuum, I can be found holed up in the bathroom while my boyfriend, Dan, vacuums the house while all the windows are open and the fans are running. Thankfully, spring has arrived and I can now stay outside while he does this. The other issue with vacuuming is that it weakens the foil’s structure and causes it to rip in places. But what can we do? If the house is left dusty, this can supply food for mould to grow. So I choose a little bit of pain while we run the vacuum over a lot of pain if this house gets mouldy!

Also to avoid mould growth and damaging this property if water is spilled, we chose to leave under the kitchen sink area unsealed. It’s only about 1 x 3 metres wide, and, yes, it does release fumes when the house heats up but still, it’s better than mould growing under the layers of foil if they were to get wet.


Since the above photo was taken we’ve put tiles down over the area to stop some of the outgassing but they are not sealed around the edges or with grout or anything, but they still do the job. I didn’t want to make a bigger problem by getting water or mould growth under the foil so chose not to seal around here. It’s a small area as you can see. (I can’t use the kitchen oven because it runs on gas and probably has been cleaned with oven cleaner. I plan to do a future post on how I tackle cooking just in case someone else needs help with that.)



The kitchen bench top is made from pine and it’s been sealed or cleaned with some type of polish or wood cleaner. The fumes on a hot day smell like Estapol and cause a headache like a tight band around my head. Guess how I solved that problem? Yes, aluminium foil. This time I used heavy duty foil to cover it. I have to be careful with food and always have a plate or glass chopping board underneath at all times because the aluminium rubs off onto my hands; I wouldn’t want that to happen to my food. The edges are sealed with painter’s masking tape so as to not cause any damage to the cabinetry.

So this how I sealed a whole house with foil!

Uber positives:
  • This foil is slippery when wearing socks and it makes a great dance floor.
  • The foil over the floorboards serves a dual advantage: it stops woodsmoke coming through any cracks!
  • Teenagers are too embarrassed to live here :)
  • It makes my house liveable.

10 Uses for Foil

During Creative Nonfiction class at Victoria University (VU) with the wonderfully inclusive teacher and writer, Michelle Fincke, one of our assignments was to write for something for Weekend Notes. We learnt about writing listicles and blog posts (Like, short articles, which, for a verbose writer, and rarely a concise one, was a challenge!) and we practised writing news articles. One of the examples up on the board was a Weekend Notes article called:’Six Uses for Aluminium Foil’; now as my readers know, I can tell you a lot about uses for aluminium foil! However, on that day in the classroom, the air being uncontaminated by fragrance, petrochemical and solvents from personal care products, the HEPA air filter supplied by Vic Uni’s Disability Services was blowing filtered air, and I, without the mask impeding on conversation, put up my hand to say, “I could write that article even better; I have a heap of uses for aluminium foil.”. I wasn’t joking, for I was sitting on a piece that had been carefully laid across my chair before sitting down for class.

My Trusty Heavy Duty Foil used to protect my clothes from fragrance chemical residue and/or fabric softeners

My Trusty Heavy Duty Foil Over a Chair Trick!

I’d already let it slip, during a previous conversation with my teacher, that I live in a house where the floor is covered in aluminium foil and we all need to wear socks so as to delay ripping it and having to change it so often, so I knew she was in on my self-depreciating joke trying to burst the bubble on my illness. We then spoke about how, yes, indeed I did have a lot of inside knowledge on the use of foil, but if I were to write about it in listicle form, then the uses would need to be audience appropriate. (The example used that day was about uses for the average consumer not yet effected by chemicals.) So, without further ado, here are my top ten uses for foil for the average chemically sensitive consumer:

  1. Chairs: Not only can it be used on public chairs (like the one above) that are ordinarily, but also wrongly, sat on by people wearing clothes washed, dried or sprayed with products containing fragrance, solvents and petrochemicals, but it can also be used over car seats to protect your clothes from petrochemical fumes embedded in the fabric/leather (How many times have you got out of a car, gone inside to shower and change clothes, then came back to your clothes later and found your clothes reek of engine oil/fragrance chemicals? How long did it take for you to recover this time after going out? Try the foil trick, you may recover faster next time and save yourself a set of clothing.) And you could also use it to cover a dentist’s chair.
  2. Floors: Have you seen those newspaper articles where they wonderfully sensationalise the stories of people who are chemically sensitive? You know the ones where they show everything wrapped in foil including the area that houses the kitchen sink? Hey, it’s not so sensationalistic. Wake up, come to my house; it’s reality: my whole floor is covered in heavy duty aluminium foil (I have more photos, and I’ll post about my new improved floor-covering technique next). My rental property has pine floors, and even though they are really old (surely old enough to have outgassed?), they release fumes that impact on my health. On days were the weather is warm, it’s blatantly obvious that the previous tenants were smokers and that the floor’s been cleaned with fragrance-based cleaners and it releases terpenes from the pine floorboards. My eyes sting and burn and I get a headache. As soon as the temperature goes over 22 Celsius I have to put the air-conditioning on so as to calm my symptoms or avoid them all together. But it’s the foil that’s really helped. This is a quick-fix solution for a rental property. (The ideal remedy, but often not possible, would be to have tiles laid; or concrete polished with low VOC sealers.) (Additionally, if you have carpet to deal with, due to the amount of VOCs emitted by the materials and glues, and possibly by any cleaning agents used, this may not work at keeping in the VOCs for very long.)


  1. Steering Wheels: Yes, I used foil tape (over other materials to protect the leather from the adhesive) on my car’s steering wheel because of the fragrance left over from the previous owner. (Foil can be reflective so if it’s put near the sun it needs to be covered with something else to protect your eyes from the harsh glare.) My only other choice to fix the fragrance-emanating-from-the-steering-wheel problem was to buy a new one; and, due to the cost, it just wasn’t an option.
  2. Money: I keep foil in my purse so I can wrap money in it. I don’t even sniff it, or get anyone else to sniff for me anymore, I just assume it has fragrance on it and fold it between the foil so that it doesn’t embed in my purse. I learned this trick from other people who have this same problem. (Don’t leave home without it!)
  3. Shopping: My partner does all our shopping but if I’m in the car we always keep a roll of foil spare so we can wrap or cover anything that’s come from a shop that sells fragranced-based cleaning products. This way fumes are not released into the cabin space; it doesn’t take long for a warm car to become extremely uncomfortable for someone sensitive to chemical irritants. (Again, don’t leave home without it.)
  4. Incremental Uses: Foil can be great to use in an emergency for when you just don’t have a solution to chemicals outgassing into your immediate breathing space. My treadmill has plastic housing over the motor. I’m not usually sensitive to plastics but lately (like, three months now), these particular plastic fumes cause a sharp headache around the sinus area in my forehead during or after my workout. Solution: I’ve laid a piece of foil over the vent, taping it down only on the side that points in my (jogging/walking) direction. My theory: the fumes are released in the other direction and soaked up by my Austin Air Purifier. (Tip: Buy foil in bulk.)
  1. Food: Yes, conventional use, I know. However, convention also suggests we use plastic cling wrap to seal in freshness. In chemically sensitive circles, due to phthalates in plastics, it’s de’ rigueur to use foil! (Get with the status quo.)
  2. Kitchen Cabinets: Again, we’re back to the “sensationalistic ‘Chemically Sensitive Person Must Cover Whole Kitchen in Foil Just to Make a Sandwich’ theme” again. I am being hyperbolic about it: it wasn’t the whole damn kitchen, it was just the unsealed particle board underneath the brand new kitchen cabinets that belonged to the house I rented four houses ago. (Do not try this yourself at home; get someone not—or at least less—chemically sensitive to do it for you.)
  3. Camping or staying in alternative accommodation: a layer of foil is the perfect—if not noisy—way to protect your clothing and bedding from a mattress that may be embedded with fragrance-chemical irritants. It can also be used to block dampness rising from the soil, if you’re sleeping outdoors.
  4. Building or Caravan Wrap: Yes, another conventional use, however, I must list it as a building wrap because as far as ‘renovating’ goes, I pray this will be the last use I have for using foil for any large scale projects, all just so that I can have a safe living space. Building foil (so long as you get one without paint or fire retardants on it) is a great product to use to seal in heat, lock out the cold and make your home more energy efficient. During our build (coming up), wrapping the house in foil is one of the jobs I’m scheduled to work on. And I’m actually very excited about that! (We are using Kingspan.)

Do you have conventional (in chemically sensitive circles) uses for foil?

Sealing Chipboard in the Kitchen (with Foil)

This is one of the first articles I wrote as a chemically sensitive patient back in 2006. I’d been sensitive to chemicals for only two years; and I thought I was so clever when we discovered a way to seal in the formaldehyde fumes coming from the brand new kitchen cabinets. (Over the next few days I have some more posts on aluminium foil and it’s uses for people sensitive to chemicals.
