Im in the middle of a remodel (completely gutted) and want to insulate the attic room.Currently I have 360deg access of the room.
Build specifics:
House is 100 years old
Floor or attic room is 2x8 16 centers.
Attic floor is 1x3 T&G
Knee wall are 2x4 2 centers
Rafters are 2x4 2' center (I don't know that kind of wood was used but it is like iron)
2 small dormers with a window each
Below (2) the attic floor joists is the ceiling for the downstairs living. This ceiling is 2x4 braced to the 2x8s above. The plan is to blow insulation between the two cavities. However, this will settle over time so first questions should I batt between the 2x8s with the batts pressed firmly against the attic floor or is the attic floor even a concern here?
----------attic floor
2 space
---------- lower level ceiling
The attic room itself Im debating between traditional batts or just use xps? Or maybe a combo, batts between the 2x4s and ¾ xps on top across the 2x4s? Im not sure if there is an issue with two different types of insulation contacting each other.
Thank you for your time. I look forward to your responses.
