Garage doors are an important part of the home that can be improved upon to increase its efficiency and temperature resistance. Polystyrene and polyurethane insulation are two commonly used materials to insulate garage doors due to their high R-values. Polystyrene is typically installed in panels, which may leave gaps where heat can leak out from the door. On the other hand polyurethane insulation is a spray foam that fills all crevices of the door and eliminates any weak spots. This ensures a tight fit and higher R-value for more energy efficiency.
Some garage doors come with ratings known as U-factors or U-values which take into account the overall cumulative energy efficiency rather than just individual elements such as door panels, frames and tracks. Generally it’s advised to have an R-value between 12 and 18 for optimal insulation effects, however, this number can vary depending on location’s climate.
Additionally, it has been suggested that insulating the wall between your house and the garage will have further reductions in heat loss rather than just isolating your garage alone.
Why Should You Buy An Insulated Garage Door?
Energy efficient garage doors not only provide practical benefits but are also good investments in terms of increasing return on investment when selling a property. Such insulated doors often have multiple layers of material such as wood, aluminum, steel etc, sandwiched between their insulation layers which help them become resistant to weather conditions such as windy climates. Furthermore, they act as noise insulators as well by dampening loud noises from outside sources while at the same time absorbing vibrations from operating garage doors so they don’t become too noisy.
