Basement Window Thermal Bridge
The status quo installation method for basement windows in Denver is the cast in place steel window buck. Obviously, it’s a major thermal bridge problem.
I’ve decided to insulate the basement on the inside of the foundation walls.
Has anyone seen or developed an easy and effective method of insulating the inside of a window buck? Attached are of photos of what I have.
Do you think it would it be worth the effort to cut the steel buck itself (after the concrete is cured) in half at the window plane? It would take 10-15 minutes each and would use up one 4″ ($3.00) metal cutting blade.
