Garage Door and Insulation | The amount of insulation you need in your garage door depends on your region. Learn about the benefits of an insulated garage door and how to select the right degree of insulation to best suit your needs.
With today's high energy costs, garage door insulation is just as valuable as anywhere else in your home. The number of uninsulated garage doors sold continues to decline as consumers demand energy efficiency for cost savings and comfort, which is more important than ever as more people use their garage as a work place or social gathering spot, and not just storage.
The thermal property of insulation is expressed as an R-value. A higher R-value reduces outside noise and helps the door operate more quietly. Many insulated doors are constructed using polystyrene or polyurethane foam.
Most polystyrene insulated door can be thicker but have a lower R-Value than polyurethane. If you are looking for thermal efficiency and a high R-Value, do not be fooled by the thickness of the door!
A polyurethane insulated door might look thinner but actually offers a much higher insulation R-value. That is because of the way the insulation expands during the manufacturing process to tightly fill the cavity between the two steel panels as it bonds to the skins of the door.
Not only does this make the door better insulated, it also makes the door incredibly strong and helps lessen noise while the door operates.
