Clearance between door and floor? (xposted to HVAC)
Hello! We are replacing doors in our house with fairly fancy ones Â better sound insulation being one of the goals.
The contractor has hung them all with rather large clearances between door's edge and floor Â partially defeating the sound-insulation... When confronted, he pointed out, that Code mandates clearance between 5/8" and 7/8" in our case, where the central air system pushes cold air into every room, but has only one return per floor (in the middle).
Is that really true? I've never seen a door Â neither in an office, nor in a hotel, nor in a show-room Â where I could insert my thumb under it!
If, indeed, the climate were to become too uneven because the doors are too tight, I'd be willing to keep the doors partially open once in a while. But when I want to watch a movie, I want to be able close the door to my child's bedroom and not worry about her sleeping.
The door-maker's instructions ask for clearance of only 3/16" Â but they don't mention differences in A/C systems...
Inserting "saddles" in the frames, or attaching "dusters" to the doors' lower edges Â the two options he is now proposing Â would be ugly and defeat the air-circulation just as well...
Any comments? Thanks! doofus
