EPS on the inside of a solid Hemlock frame
I own a 1964 Duplex in Montreal. I have selectively gutted some key rooms for reno.
Once of which is my kitchen. I would like to improve the efficiency of the assemblies I have opened up. I have new windows.
I don’t know what my building structure type is …but it can it is SOLID – characterized by a series of nail,connected Hemlock (pruche) planks that are structurally notched for spans.
Here is the profile OUT to IN.
asphalt impregnated fibre board “tent test”
asphalt paper #15
2 1/2 inch Hemlock planks
** #15 felt paper
My plan was and hopefully still is to use TYPE II EPS (ISOLOFOAM HD) 1 3/16″ directly nailed to the structure, followed by either some kraft, 15 felt or membrain or nothhing. The structure itself is quite drafty, so I caulked and sprayfoamed the joints between planks.
I am now struggling with the decision. Am i making a mistake by putting structure into the cold?? I cannot afford to build a cavity wall due to space constraints. What do y’all think / recommend?
What should I do and why? also..what is the framing I described called?
Considerations, ceiling joint spaces etc?
HELP! I need to get the job done for the holidays and this is a sticking point.
