Insulating concrete walls in garage.

Consider all aspects of insulating your garage not just the walls but also the garage doors and the ceiling particularly if you plan to add a heating and or cooling system. Before you can install these panels you ll have to do some demolition. So before insulating go around the garage with a can of low expanding spray foam and seal all gaps and cracks that let in the daylight. There are two main ways to insulate a concrete garage.

The first is to use a fibreglass insulation much like the type found in any typical loft. You can insulate the walls ceiling and door of the garage to the highest r value possible but if you fail to fill those air gaps you ll still be wasting a lot of heat. Adding 2 inch thick insofast panels will bring your walls to r 13 30 percent more than the iecc minimum. Cinder blocks are uniform concrete and cinder blocks used in the construction of low budget walls and foundations.

For example while an epoxy coating will add a protective layer to the floor it won t necessarily add insulating values. Remove all the trim from the exterior walls window and door casings baseboards crown molding you name it and rip the drywall and studs off the block walls. Air sealing the walls is different than insulating them but they go hand in hand. And don t forget to take flooring into account.

You re spending your hard earned money on insulating your garage. Sealing the gaps behind the walls will set you up right from the start. The cinder block material is light and porous.
