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!

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.
