Thats what I was thinking...thermal bridging....Thought it was a good energy savings idea
They though it was a good energy savings idea. I don't, the metal will conduct the temperature delta right through it.Thats what I was thinking...thermal bridging....
Gotta be a little better no? If it ends up air sealed that is... Plus the sound?They though it was a good energy savings idea. I don't, the metal will conduct the temperature delta right through it.
It may have some value to air sealing if they foam the flange after it it installed in block or solid wall
You'll still have thermal bridging through the frame unless you use a frame with a thermal break, which is available from several hollow metal manufacturers.Thats what I was thinking...thermal bridging....
