There are 2 primary types of insulation that are used for garage doors. They are:

• Polystyrene: A rigid foam board, this insulation is more commonly known as Styrofoam. Used in two- and three-layered doors, it’s sandwiched between two layers of steel. R-values will vary from R-6 to R-9. You can also find this type of insulation in hardware stores for a do-it-yourself installation project.

• Polyurethane: This insulation starts as a thick liquid and expands as it sets, ensuring it completely fills the cavity of the garage door. Commonly known as “foamed in place” or FIP doors, most manufacturers offer this style of product. Found most often in three-layer garage doors, this style of insulation offers R-values of R-10 to R-19 and gives the door a solid structure to reduce noise and improve lifespan.

You can find other types of insulation kits for do-it-yourself insulation at local hardware stores or online. These types of insulation offer short-term solutions, such as seasonal insulation, but are subject to wear and tear, as they are not designed for long-term durability, and must be securely fastened to the door. Be aware these kits also do not generally provide 100-percent insulation coverage.
