Garage Insulation

​Insulation for Garages

Garage insulation isn't something that most people think about on a regular basis. The majority of homeowners insulate their attics and walls well because they realize how much money they can save on their energy costs by doing so. Garages, on the other hand, are unconditioned spaces that are neither heated nor cooled, making insulation impractical. Is that the case?

When a garage isn't adequately insulated, it might get as hot or cold as the outside temperature. With uninsulated walls and a common ceiling between the garage and your home, this may soon become a significant source of energy loss in both the garage and your home. Furthermore, hazardous odors from your garage, such as those released by automobiles, fertilizers, paints, and other chemicals, could easily seep into your home.

The most effective way to keep harmful factors out of your home is to insulate the walls and ceilings that connect your garage and your home. You do, however, have a number of options for insulating your garage walls, and picking the best one can make a big difference.

Batt insulation, which has long been a popular choice for insulating attics and walls, is often the first type of insulation considered by homeowners when insulating their homes. Despite having R-values (insulation performance ratings) that are equivalent to other insulating materials, batt insulation is not the best choice for garage insulation.

Depending on the application, batt insulation is applied in rolls or batts. Because the insulation batts do not completely seal the spaces between the wall and the ceiling, gaps can form between the insulation rolls. The holes allow energy to leave your home while also allowing contaminants to enter. Batt insulation is also susceptible to moisture damage, reducing its ability to offer insulation even further.

Foam-board insulation, which is solid sheets of molded polystyrene, gives equivalent R-values while being less bulky than batt insulation. Although foamboard insulation is effective, it does not entirely fill all of the gaps in your wall, and gaps can occur between the insulation sheets.

Insulation that fills in all of the gaps and creates a tight seal around the walls and ceiling of your garage will help you save money on energy bills while also limiting fume seepage. Spray foam garage insulation begins to spread and fill in all voids as soon as it is applied. Spray foam insulation has the same R-values as foam-board insulation of comparable thicknesses, but it is more resistant to moisture damage.
