Home Envelope Part 3: The Hard Stuff

By The Proulx-Coll Household

Finally, there’s a really big projects like insulating our main walls, insulating our foundation, and insulating our attic.

There’s a few ways you can improve your exterior walls insulation.  One way is by the outside.  You can remove the siding, add some insulation and then replace the siding.  One of the benefits from doing it from the outside is that it doesn’t impact your living space.  If you do it by the inside, you have to remove all your walls, add some insulation and then replace your walls. That’s a pretty invasive job, so generally you could do it a little bit easier from the outside.

In our case, it will be very costly because our siding is made of asbestos.  So whenever you take the asbestos shingles off, the fibres can go into the air and you don’t want to breathe those in. So taking those off would be really expensive.  We are still working with contractors to get quotes and plan this out, so stay tuned!

A relatively easy way to insulate your basement is to add insulation on the inside of the basement walls.  (This is relatively easy if your basement isn’t finished yet!).  You could used hard foam boards or sprayed with a closed cell foam.  In our case it’s a little bit more complicated because we have some water that seeps through our concrete.  So the first thing we need to do is make sure that there’s no water that will seep through the concrete wall and the only way we can do that is from the outside.   This would involved digging all around our foundation, fix the foundation, put a membrane to prevent water from coming in.   Now you can imagine if we dig a huge trench around our house, it would be a really big job too!  We are also working with foundation experts to evaluate the cost of doing this.  Stay tuned!
