| Vaulted Ceiling insulation
I am in the process of converting the remainder of my garage into a 325sqft live room with a vaulted ceiling at a 6/12 pitch (same as the roof line). My question today is regarding ceiling insulation and protecting the live room from obvious outside noise though most notably the sound of heavy rain pounding on the roof. My current plan calls for a tongue and groove ceiling insulated with R38 fiberglass batting plus a 1” air gap between the insulation and the roof (as required by code). All of this in a 12” vertical gap between the roof and the tongue and groove. I chose tongue and groove as my finished ceiling material due to the exposed trusses and the ease of manipulating the T&G around the trusses. It would have been a complete nightmare trying to sheet around the exposed trusses. What are some of your opinions on how to beef up my ceiling insulation? Or is it enough? I kind of doubt it. I have considered installing rockwool above the fiberglass batting to increase the R value of the ceiling. I’m open to any suggestions. Thank you in advance. -ignore the ceiling fan on the virtual pic  |
