Insulation for a Garage Door

Typically, a form of foam insulation is used in garage doors. Overhead Door’s steel and wood garage doors have:

  • Polyurethane insulation: This is one of the most common types of spray foam insulation and has been used for decades. Spray foam insulation is effective at helping prevent air infiltration.
  • Polystyrene insulation: A type of rigid foam insulation, polystyrene insulation has long been used in both the residential and commercial industry.

Our insulated garage doors are not only energy-efficient but can help better protect the interior of your garage and keep your home more comfortable all year long. They also tend to operate more quietly.
