If you decide to replace your door, there are several factors to consider when selecting a replacement.
Materials
Garage doors come in a variety of materials, and each offers its own insulation potential. Let’s look at some of your choices:
Layers
When selecting a steel door, you can also choose between one-layer, two-layer, and three-layer options. Here’s what that means for you:- One-layer: Known as pan, hollow back, contractor-grade or non-insulated doors, single-layer doors are often installed as an extremely cost-effective option.
- Two-layer: The garage door insulation temperature difference comes from a one-layer door is that foam insulation panels are inserted into the hollow cavities on the inside of the door, enhancing the door’s insulation value but not necessarily improving the quality of the door.
- Three-layer: This door features a layer of steel on the exterior and interior, as well as a solid insulated core. Four polystyrene and polyurethane insulation options are available for the core.
