Should I Buy an Insulated Garage Door?

Wednesday, December 7 2016 10:17 AM

If you're shopping for a new garage door, you may be wondering if an insulated model is right for your home. A garage door can provide a high return on investment, so it’s important to choose one that will also provide functionality and long-lasting quality.

Insulated garage doors have two layers of steel with polystyrene (styrofoam) or polyurethane (spray foam) insulation in between. They are thicker and more energy efficient than uninsulated doors, which makes them ideal for the hot or cold weather in Kansas City. If your garage is attached to your home, an insulated door can help lower your heating and cooling costs. 

Benefits of an Insulated Garage Door:

Increased energy efficiency

The R-value can help you determine how efficient a garage door will be at insulating your garage and home. Insulated garage doors can provide an R-value of 12-18 as opposed to uninsulated garage doors, which have a much lower R-value.

Buffer zone

Seven out of ten homeowners use their garage as the main entrance of their home. By moderating the temperature in the garage, you're reducing the amount of hot or cold air entering your home.

Quieter operation

Insulated garage doors are quieter because the insulation dampens vibrations. It can also help to reduce noise from outside the door.


Insulation is filled between two steel panels, creating a durable yet lightweight door that’s less likely to dent.

Return on Investment

A new garage door can provide a return on investment of 91.5%, according to the 2016 Cost vs. Value report.

Which Type of Insulation Should I Choose?

Soundproofing, temperature control, and sturdiness of your garage door will be affected by your choice of insulation material. Polystyrene and polyurethane are the two most common materials used for insulation in garage doors.

Polystyrene Insulation:

  • Can provide an R-value of up to ten, depending on the thickness of the foam.

  • Is inserted in sheets and attached to the garage door’s individual sections.

  • Is usually thicker than polyurethane which makes the garage door thicker.

  • Popular because it’s a good value and simple to install.

Polyurethane Insulation:

  • Is generally the more expensive choice due to the higher density of the foam.

  • Has a higher R-value than polystyrene, which means it’s more energy efficient.

  • Comes in a spray foam.

  • Thinner than polystyrene, making it ideal for tight spaces.

  • Bonds directly to your garage door, making it more sturdy.

Now you’re ready to choose the insulation that best fits your needs and budget.
