Should I insulate garage ceiling?
It isn’t important to insulate the ceiling between the attic and the garage because those areas are not affected by a home’s heating and cooling system.
If these walls are not insulated, the temperature of the garage can affect the rooms and make the house’s heating and cooling system work harder to compensate..
What R value do I need for my garage ceiling?
Typically these will be constructed from standard 2-by-4 studs which will define the amount of insulation that you can have installed. You should be targeting an R-Value of R-13 or R-15 in these areas to properly maximize your insulation in this application.
Can you use r13 in ceiling?
You want r13 for 2×4 walls, r19 for 2×10 floors, and r30 2x for rafters or r38 for truss attics. The majority of your heat loss will be the ceiling, as heat rises. The second worst area will be windows and the garage door.
What insulation should I use in my garage ceiling?
Fiberglass is the most commonly used type of insulation in garages (just as it’s the most popular type in homes). It’s sold in pre-cut batts and long blankets that fit between wall studs and ceiling joists.
Is r19 good for garage ceiling?
Insulation in your walls and ceilings slows down this heat transfer. Any good insulation material, such as fiberglass, foam board, spray foam, etc., all act to slow down heat transfer out of your home. So R19 is better insulation than R13, and R30 is better than R19.
