Hello. I have a 110 yo Victorian style home in north NJ with an unfinished attic (tall roof peaks about 10 feet above floor) with vermiculite under attic floorboards above second floor ceilings. I would like to make the attic into a 4 season living space. I also want to install the air handler for the entire house in the attic with the main duct running along the triangular space behind the proposed knee wall and the roof rafters. The individual branch ducts will be run off the main duct between ceiling joists across under the attic floorboards when vermic is removed ( I understand issues with vermic).
My thought is that if the attic is an insulated envelope...if wall and roof rafters are insulated, I should not have to wrap the A/C ducts... Even if I don't actively cool or heat the attic. Is this a reasonable guess?
1. Thinking I would insulate the entire roof rafters- attic floor to peak - sidewalks, and also keep the remaining vermic sealed under floorboards without ducts. I have read about the airflow baffles to place between roof and insulation.
2. Unsure about where or if to install vapor barrier I don't know if the soffits are vented. There is ventilating panels on outside under eaves but don't see light from attic.
I would appreciate tips or pointers to a plan to implement this. Thanks.
