Types of Garage Insulation

Foam Board Insulation – Foam board insulation is one of the most popular forms of insulation used in garages. It is a rigid material made from polystyrene, polyisocyanurate, or polyurethane and is available in various thicknesses and densities. This insulation is easy to install and can help reduce energy bills. Its main advantage is its ability to provide excellent thermal performance, as well as its resistance to moisture and mold. It also comes with a long lifespan, making it an ideal choice for garages.

Fiberglass Batts – Fiberglass batts are a popular option for insulating garages. This type of insulation is made of fibers of glass, which are held together using a binder. It is lightweight, easy to install, and provides good thermal performance. The batts also help to reduce air infiltration, helping to keep conditioned air in the garage. As an added benefit, the batts are also fire-resistant.

Spray Foam – Spray foam is an excellent option for insulating garages. It is made from two main ingredients; polyurethane and isocyanurate. This insulation is applied in liquid form and expands to fill any gaps and cracks. It provides an airtight seal, making it an ideal choice for garages that are located in areas of extreme temperatures. Spray foam is also highly resistant to mold and mildew, making it an excellent choice for garages that are prone to moisture. Additionally, it has a long lifespan and can help reduce energy bills.

How to Install Garage Insulation

Selecting the Right Insulation

When selecting the right insulation for your garage, it is important to consider the type and amount of insulation you need. There are two main types of insulation that can be used in garages: fiberglass and spray-foam insulation. Fiberglass insulation is the most common and is available in rolls or batts. It is designed to fit between the studs and joists of the walls and ceilings of your garage. Spray-foam insulation is generally more expensive, but is more effective at insulating, as it can cover difficult angles that fiberglass insulation may not. It also helps reduce air leakage, which is an important benefit for a garage.

Preparing the Garage

Before installing insulation, you need to prepare the garage by sealing any air leaks. This includes sealing any cracks or gaps in the walls or ceilings, as well as any gaps around windows and doors. Additionally, any exposed wiring should be insulated, and any exposed pipes should be sealed. Once the garage is properly sealed, you can begin installing the insulation.

Installing the Insulation

Installing insulation in a garage is a relatively simple process. For fiberglass insulation, you will need to measure the walls and ceilings, cut the insulation to fit, and then install it between the studs and joists. With spray-foam insulation, you will need to use an applicator gun and spray the insulation onto the walls and ceilings. Once the insulation is installed, you will need to cover it with drywall or other materials to protect it from the elements and to improve the appearance of the garage.


Garage insulation is an essential part of any home improvement project. It not only helps to keep your garage warm and dry, but also provides an added layer of protection from the elements. From improved energy efficiency to better soundproofing, the benefits of garage insulation are numerous. In addition, insulating your garage can help reduce noise pollution and improve air quality. With so many advantages, it’s no wonder that garage insulation is a popular choice among homeowners.

Insulating your garage can be a relatively simple and inexpensive project. With the right materials and a bit of effort, you can transform your drafty space into a cozy and comfortable environment. In addition to providing comfort and improved energy efficiency, insulating your garage can also help to reduce your heating and cooling costs.

For those looking to take their insulation efforts even further, there are options available to further improve your garage’s energy efficiency. These include adding insulation to the walls and ceilings, installing insulated doors and windows, and using reflective insulation to reduce heat transfer. Further research into these options can help you make the most of your insulation project.

Overall, garage insulation is an effective and inexpensive way to improve the comfort and energy efficiency of your home. From improved energy efficiency to soundproofing and air quality, the benefits of garage insulation are numerous. With the right materials and a bit of effort, you can easily transform your drafty space into a cozy and comfortable environment.
