Energy-Efficient Doors
Choosing the right insulation material is an important step in selecting an energy-efficient garage door that helps maintain a more consistent temperature inside your garage. The thermal performance of insulation is measured by its R-value. In general, a higher R-value means better insulation, which can lead to lower energy costs, reduced outside noise, and smoother door operation.
Most insulated garage doors are constructed using either polystyrene or polyurethane foam insulation. Polystyrene-insulated doors are typically thicker but provide a lower R-value. Polyurethane-insulated doors, while often thinner in appearance, offer a significantly higher R-value. This is due to the manufacturing process, where the polyurethane foam expands to tightly fill the cavity between the two steel panels and chemically bonds to the door’s interior and exterior skins.
This bonding process not only improves insulation performance, but also adds strength to the door and helps reduce vibration and operating noise, resulting in a quieter, more durable garage door system.
