FAQ

Should I insulate my garage?

Yes, insulating your garage is a smart investment—especially if it’s attached to your home. An uninsulated garage can allow heat to escape in winter and enter your home in summer, making nearby rooms uncomfortable. Proper insulation helps improve energy efficiency, regulate temperatures, and make the garage more usable as a workspace, gym, or storage area.

Does garage insulation reduce energy bills?

Yes, garage insulation can help reduce energy bills by minimizing heat transfer between your garage and your home. This is especially true for attached garages, where uninsulated walls and ceilings can cause energy loss. By keeping temperatures more stable, your HVAC system doesn’t have to work as hard, which can lead to lower monthly utilities.

What is the best insulation for garages?

The best insulation for a garage depends on your goals, budget, and how the space is used:

• Spray foam insulation offers the highest performance by sealing air leaks and improving efficiency.
• Fiberglass insulation is a cost-effective option for walls and ceilings.
• Cellulose insulation is an eco-friendly option with good thermal performance.

A professional can recommend the best solution based on whether your garage is attached or detached and if you plan to heat or cool the space.

Can I heat or cool an insulated garage?

Yes, once your garage is properly insulated, it becomes much easier and more cost-effective to heat or cool. Insulation helps maintain stable temperatures, allowing you to use space heaters, portable AC units, or even extend your HVAC system into the garage. This makes the garage comfortable year-round for work, storage, or additional living space.
