Question by Rubber Ducky: What green building system has the best thickness to r-value ratio?
I am designing a hypothetical multi-story building in Toronto, Canada. The site is 15′ wide, which means that I need a thin wall with an amazing r-value. I also cannot use wood frame construction. What building system, from exterior to interior, can I use to have the best r-value to wall thickness ratio, while still being able to support 4 stories of concrete slab flooring.
Best answer:
Answer by itsbob1
Structural steel for vertical support. Metal stud framing with Styrofoam panels, stucco exterior with sheetrock interior. R30 can be done with the sandwich style exterior walls.
