You re spending your hard earned money on insulating your garage. 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. 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.

That air comes in anyplace it can including gaps in the insulation behind your walls. 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. Sealing the gaps behind the walls will set you up right from the start. Air sealing the walls is different than insulating them but they go hand in hand.

And don t forget to take flooring into account. Before you can install these panels you ll have to do some demolition. As such a lot of interior heat can escape through cinder block walls during the winter. The second is to use a coated foam sheet like the ones manufactured by kingspan or celotex.

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. The cinder block material is light and porous.
