Now House Project Update: Exterior walls and basement floor improvements

Above is the ad running in our September issue of the Ontario Construction Report on the "Now House" project. We will be covering the project in an indepth feature article. You can also check out the "Now House" site for regular updates on the project and see photos of the work being completed. Below is the latest post.

The existing aluminum siding was carefully removed from the house in order to reuse it after adding significantly more insulation to the exterior walls. The existing insulation R-8 rockwool will be maintained. A frame will be built around the exterior walls into which foam insulation (BASF Walltite R31Insulation/Air Barrier System) will be sprayed. This will create a second layer of continuous insulation preventing cold bridging and bringing the exterior wall insulation up to R-39. Insulating from the outside creates a lot less disruption for our homeowner.




Basement floor

On the other hand, jackhammering out the basement slab sent the homeowner and his dog out of town for a few days. The concrete slab is being removed to better insulate the floor and prepare it for installation of radiant floor warming.
