Types of Garage Door Insulation

If you plan on heating your garage, it’s important that the garage door is properly insulated. When you’re searching for the right garage door insulation, there are a variety of different types that you can choose, each of which can be advantageous. Keep in mind that the higher R-value ratings equate to better insulation. By combining quality insulation with a weatherstripping seal at the bottom of your garage door, you should be able to keep air from leaking.

Fiberglass Garage Door Insulation

This is a very common type of insulation that’s available in a loose-fill form or in a thick blanket form. The fiberglass insulation with the highest R-value will have a higher density. This type of insulation is commonly used because of its versatility and affordability. When placed in your Los Angeles garage door, you will significantly reduce the amount of heat that escapes from the garage.

Spray Foam and Rigid Foam Insulation

Spray foam is a highly energy-efficient material that’s considered to be fantastic for air-sealing purposes. While this form of insulation is typically used for higher-end applications, it’s ideal for garage doors if you’re looking to make your home more energy-efficient. As for rigid-foam insulation, this type comes in sheets that range in thickness from 1-4 inches. The polystyrene form of this insulation is very similar to Styrofoam and is considered to be ideal. Keep in mind that only some types of rigid foam insulation are known to be fire-resistant.

Cellulose Insulation

This is a kind of unique loose-fill insulation that consists mainly of recycled newspaper. Before being used as insulation, it’s treated with a premium fire retardant and then blown into the garage door. The aeration that occurs when sending the insulation into the door will cause it to expand and become denser. Since this is of the loose-fill variant, it can only be paired with a finished garage door.
