I live in a house that was built in 1958. I am looking for the R value of my brick veneer walls. For that I would need to know how the wall was built (there should be the brick, some sheating, insulation etc. This is the part that I am missing: the layers that were used to build my walls.
This is in Toronto Canada. If anybody is familiar with this topic I would really appreciate some help
Here is what a wall looks like. The house in the back is identical with mine
There is good chances that my wall looks like this:
I am using the Heat2000 program to calculate the thermal values for my house. I decided to go with the below settings. This will give me a conservative R value of 13.5. I will use a second iteration with no batt insulation and see what I get.
I need this in order to properly size the furnace, the contractors that I have contacted for this are too lazy for this so I will have to do it myself
