Whether you’ve recently added a garage to your house or you are in the process of building a new home with an attached garage, you’ve likely shopped around for the perfect garage doors. But it’s not as simple as choosing a functional door that matches your home’s aesthetics. You will also have to decide whether or not you should pay extra for insulated garage doors.

Why Do Insulated Garage Doors Cost More?

The R-Value and the STC rating measure the energy efficiency of garage doors. 

R-Value represents the garage door’s ability to block cold or hot air from passing through. The higher the R-value, the better it will do at keeping extreme temperatures from entering the garage. 

The STC rating measures the door’s ability to block outside sound from entering the space. The higher this rating is, the less sound will penetrate the door. 

The extra steel and insulation materials required to block extreme temperatures and outside sound are why the increased price of insulated garage doors. Garage doors utilize two primary materials as insulation: 

  1. Polystyrene
  2. Polyurethane

If you are on a budget but still want a level of insulation in your doors, polystyrene is a good choice. It offers basic insulation at an affordable price. 

However, the best insulation for garage doors is polyurethane. The higher density makes it a better insulator, adds durability to the doors, and resists shaking and vibrations.
