How to Insulate A Garage for Maximum Efficiency

A properly insulated garage can make a big difference in the overall comfort of your home and save you money on your energy bills. By properly insulating your garage, you can prevent air leakage and keep warm air in during winter months and cool air in during summer months. Here are some tips on how to insulate garage for maximum efficiency.

Materials You Will Need

Before you get started, it's important to have the right materials on hand. For this project, you will need insulation batts, foam board insulation, foil-faced tape, weatherstripping foam, a caulk gun, and caulk. Make sure you purchase quality materials that will last a long time and provide the best insulation possible.

Insulation Batts

Insulation batts are ideal if you have unfinished garage ceiling insulation with an unfinished ceiling or walls that are not already finished with drywall. Insulation batts come in a variety of sizes and thicknesses so make sure to measure your space before purchasing them. With insulation batts, cut them to size and then fit them into place between the joists or studs of the walls or ceiling of your garage. Secure them with tape or nails as necessary.

Foam Board Insulation

Foam board insulation is ideal for an insulating garage where walls are already finished with drywall or panelling since it doesn’t require any additional framing or installation steps like batt insulation does. Foam board insulation comes pre-cut in 4x8 foot panels that can easily be fitted into place between joists or studs of walls and ceilings using construction adhesive or screws as needed. Simply secure the panels into place and seal any edges with foil-faced tape to ensure there is no air leakage around the edges of the boards.         

Weatherstripping Foam & Caulk Gun/Caulk

It's important to seal any gaps around doors and windows with weatherstripping foam or caulk to prevent any outside air from entering through cracks or crevices around those areas. Weatherstripping foam comes in pre-cut strips that can be easily fitted around doorways while caulk should be used for smaller gaps where necessary. Use a caulking gun to fill larger gaps with caulk if needed as well as any cracks in the drywall where air may escape through as well. This will help keep all outside air out of your home while still allowing ventilation when needed without compromising energy efficiency too much.
