I live in an 80-100 year old house (not sure of exact age...my great grandfather built it, and it has been passed down for a few generations). He built it out of whatever was cheap at the time, so in many of the rooms we found things like newspaper used for insulation (which was actually kind of awesome). We live in Ontario, Canada, so it can get pretty cold here.
I will soon be renovating the master bedroom. Most of the rest of the house has already been renovated, this is the last remaining original room. This room has seen some water damage from a leaking roof (since fixed), and drywall damage from age and clumsy people.
Once the weather is nicer, we plan to:
- Gut the room
- Install new electrical - replacing the old probably crumbling wiring and adding a new circuit for additional outlets (the wire for which is already run into the attic during a previous renovation).
- Add ceiling lighting and wall switch
- Replace/add new insulation
- Re-drywall, paint, carpet, etc.
As luck would have it between my family and myself we have all the skills to do the drywall and electrical work. The part we are unsure of is what kind of insulation we need, and how to put it in.
This view from outside shows where the master bedroom is. The room itself is 12' x 12'. There are attics on 2 walls and the ceiling, and one outside wall.
This room is freezing in winter! I can feel the cold practically blowing through the walls. This makes my wife unhappy, so must be fixed.
Since the drywall is broken on the outside facing wall, I can see what is already there:
This area is probably narrower than the rest of the wall, since it is right next to a window on the left. The pink foam at the bottom is what I crammed in there temporarily and covered the hole with vapour barrier plastic.
I can access the attic to add insulation from above, or I can install it from below before drywalling the ceiling.
So, my questions are:
- What kind of insulation do I need for the 3 walls and ceiling? There are dozens of different kinds and ratings of insulation at the local building stores, and I have no idea what to pick. I don't want to spend more than I need to, but I also don't want to freeze.
- Do I need vapour barrier as well?
- For the side attics, where do the insulation and vapour barrier go? Inside the wall, or against the roof? Which side does the vapour barrier go on? -
