Ok after looking here I can't find the answer, so I'm going to ask.
I have three bedrooms and two baths over my two car garage. The garage ceiling is sheetrocked and finished but does not have any insulation, thus the rooms get chilly versus the basement ceiling which has roxul sound insulation then drop ceiling. So what to do? Oh one bath subfloor was water damage so when all the subfloor was removed to lay tile I used R30 unfaced fiberglass pink insulation (I didn't know better then) installed then OBS subfloor then ceramic tile...this floor stay a nice temp compared to the hardwoods and other bath with ceramic tile.
1) Remove drywall (reuse?) install R30 faced (facing towards conditioned side) insulation then re-install old drywall. -->I've never re-used drywall, but if possible this is the very cheapest method.
2) One I want to use but highest price. Demo ceiling drywall. Fix floor creaks but screwing OBS subfloor to hardwood from below. Have 2" closed foam spray insulation installed. Then R13 faced insulation. Then drywall.
3) Possible easiest fix but largest risk and problematic. Cut holes and use fill with loose fill insulation. Then seal any holes. --> In a way I love this idea because it is so simple but (1) leaves creaky hardwoods above, (2) causes problems if I need to access HVAC runs that are covered by drywall, and (3) chance the drywall won't hold the weight [I don't know drywall's true age].
So what do you think? #2 is the best choice because it completely seals the garage thus preventing any CO2 from escaping into the living quarters, has the highest R value, and best soundproofing. But will cost about over $8 a sqft and I don't plan to stay here more than two years...but could be here up to four.
I'm at a loss...give me some guidance. Anyone who has had these problem and did something let me know. Thank you!
