Glass garage door in LR?
We're thinking seriously about putting a large (8'0" tall x 10'0" wide) glass garage door in our living area, in the place of french doors. Not surprisingly, our builder thinks this is ridiculous. I would love to hear what you all think.
By way of background, our builder argues there's no way the door can be tight enough to guard against serious air infilitration, and that we'll blow our goal of a 30 HERS rating. He thinks it'll "flop around" in the frame.
I've communicated extensively with the company (BP Glass Garage Doors) about the insulation issue and here's what they've shared:
"Our Insulated Line doors include the Air Leakage resistance (NFRC) package. Our Insulated Line glazing consists of 1/2" argon filled Insulated Glass Units. Each unit is sealed in place when the doors are fabricatedThe glazing is wet sealed within the frame.
We also provide 2 sets of perimeter weather strip. One is mounted from the exterior and the second is mounted from the interior. The door will sit on a 4" wide, Ã¯Â¿Â½" tall ADA compliant beveled solid clear anodized aluminum threshold. Of course the bottom of the door has its own weather strip that will seal with the threshold. This completes the package."
We have exceeded all the requirements for Air Leakage per the 2009 International Energy Conservation Code(IECC)."
And, best of all, The door's CFM rating is .06, which is well below the residential standard.
So, what do you think? Can this door work in a super-insulated house? (It would be on the North side, btw.)
