Is Garage Door Insulation Worth It?

What is Garage Door Insulation?

Garage door insulation is layers of high-density foam that help regulate the temperature of your garage. Like insulation in your walls helps keep your home’s temperature comfortable, garage door insulation reduces the amount of energy loss through your garage door to keep the space more comfortable. This means less heat loss in the winter and less cooling loss in the summer. Insulated garage doors are valuable in especially cold or warm climates where the garage can become a major source of energy loss.

Types of Garage Door Insulation

Insulated Garage Doors

Non-Insulated Garage Doors

Non-insulated garage doors have no insulation, just the metal or vinyl of the garage door panels. Without insulation, your garage door provides little protection against the outside elements, meaning your garage is hot in the summer and cold in the winter.

Two-Layer Insulated Garage Doors

Above non-insulated garage doors are two-layer insulated garage doors, which include the garage door panels plus an exposed layer of polystyrene insulation. Polystyrene insulation is a dense foam board that is attached to the back of your garage door. Two-layer insulated garage doors increase your garage’s energy efficiency but not as well as three-layer ones.

Polyurethane Insulated Garage Door

Three-Layer Insulated Garage Doors

Three-layer insulated garage doors are the top-of-the-line option for garage door insulation. Manufacturers spray polyurethane foam between the front panels of your garage door and a metal backing. This foam gets sprayed into every part of the door and hardens, ensuring maximum strength and energy efficiency for your overhead door. 

Four Reasons to Invest in Garage Door Insulation

Energy Efficiency 

Insulated garage doors significantly increase your garage’s energy efficiency compared to non-insulated ones. The insulation in your garage is measured by its R-value, which calculates thermal resistance to heat flow. The higher the R-value, the more effective your insulation will be. Find a new garage door with a high R-value to get the best energy efficiency for your home and reduce heat and cooling loss. 

Noise Reduction

If you have a noisy garage door, you know how frustrating it can be to hear the door opening and closing from across the house. However, garage door insulation reduces garage door noise by absorbing the vibrations as the door operates. Insulated garage doors are especially beneficial if you have a room above or beside the garage. 

Temperature Control

With a non-insulated garage door, you must deal with a freezing cold garage in the winter and a hot box garage in the summer, making it impossible to enjoy any time spent in the space. However, an insulated garage door regulates temperature, giving you a more comfortable place for projects, working out, crafts, and more. 


An average metal garage door is prone to dents and dings from stray balls and lawn equipment. But with an insulated garage door, you get greater durability, so your overhead door can withstand weather, kids, and accidents with minimal damage. The added durability also extends the lifespan of your garage door, making it an investment that pays off for many years.

More Tips for Increasing the Energy Efficiency of Your Garage

If you’ve invested in an insulated garage door but still want a garage that is comfortable for long hours of work year-round, here are a few more tips for increasing your garage’s energy efficiency.

  • Heated Floors — Many garages are built on a concrete slab, making them difficult to heat. However, heated floors are a great solution to reduce energy loss and keep your garage comfortable. Although this is a pricy investment, if you use your garage as a workshop, gym, or home office, it may be worth it.
  • Insulate the Garage Ceiling and Walls — If your garage ceiling and walls are not insulated, they are also a major source of energy loss that your insulated garage door cannot combat. It is essential to insulate the walls connected to the outside and ensure a firm seal around any garage windows to maintain a comfortable temperature in your garage. 
  • Eliminate Gaps Around Your Door — Properly sealing all around your garage door is also important to prevent air from getting in and out of your garage. Ensure the weatherstripping along the bottom seal and the seals around your garage windows are tight, without any gaps.
