Determine if a garage door with a thermal break is the right choice for your climate and usage.
What is a Thermal Break?
In an insulated garage door, a thermal break is a continuous barrier of non-conductive material (like dense rubber or polyurethane) that separates the inner and outer steel skins of a door panel. This barrier stops the transfer of heat or cold from the outside to the inside through the metal, dramatically improving the door's insulating properties and overall energy efficiency.
