Most Frequently Asked Questions about insulated Doors

The R-value is a calculation designed to evaluate the thermal efficiency of a material. The greater the R-value, the more effectively an insulating substance will keep heat out. Insulated garage doors are designed to keep the outside temperature out, saving you time and money. Garage doors with an insulated surface can serve as a barrier against air penetration, preventing cold air from seeping into your home via your garage door. Insulated garage doors come in a variety of styles and colors to suit any decor.

The Overhead Door Company of Puget Sound is a Washington-based firm that creates insulating garage doors for both residential and commercial use with a selection of R-values to fit your needs. Insulated doors are a smart way to save time and money on utility bills.

Overhead Door Company of Puget Sound offers insulated garage door services in Seattle, Spokane, Tacoma, Olympia, Bellevue, Everett, and all of Western Washington that far exceed the energy-efficiency of classic steel garage doors. An insulated door will help with temperature regulation, keeping your garage more controlled and energy-efficient. Contact us today to get started on your garage project.

Consider a well-insulated residential garage door if your garage will be exposed to extreme temperatures, whether hot or cold. The R-value is a calculation that quantifies a material’s thermal efficiency. The R-value of an insulated garage door is typically between 1 and 3, while that of an non-insulated one is generally around 0.9 to 1.4. The higher a door’s R-value, the more effectively it insulates you from the weather.

This R-value is made possible by a continuous layer of foamed-in-place polyurethane insulation or polystyrene insulation sandwiched between two layers of rust and corrosion-resistant steel. These doors also feature between-section seals that provide added resistance to air infiltration, as well as bulb-type bottom seals that guard against wind and rain.

The Overhead Garage Door of Puget Sound also provides a variety of heavy-duty, wind-load doors designed to withstand hurricane-force winds, whether you live in a coastal region or area with unique wind codes and rules. We build custom residential garage doors to meet or exceed any state or county wind-load code for classic steel garage doors.
