The R-value is a measure of thermal resistance used in the garage door and construction industries to determine the effectiveness of insulation materials. It represents the material’s ability to resist the flow of heat through it, with a higher R-value indicating better insulation.

A garage door R-value is calculated by dividing the thickness of the insulation by its thermal conductivity (how easily it conducts heat). For example, if a garage door has an R-value of 10, it means that it will resist the flow of heat 10 times more effectively than a garage door with an R-value of 1. A higher R-value means better and denser insulation.

There are several advantages of having a garage door with a higher R-value:

Better thermal insulation: The primary advantage of higher R-value insulation is that it provides better thermal insulation. The insulation is more effective in resisting the flow of heat, resulting in less heat transfer between the interior and exterior of the garage.

Reduced energy costs and sustainability: Insulation with a higher R-value reduces energy costs by reducing the amount of energy required to maintain the desired temperature inside your garage and home. A well-insulated garage door helps keep the indoor temperature more stable, resulting in lower utility bills by reducing the need for heating and cooling systems, which also contributes to reducing carbon footprint.

Better sound insulation: Insulation with higher R-values provides better sound insulation by reducing noise transmission from outside.

Increased home value: A home with a garage door that has a higher R-value insulation may be more attractive to potential buyers as it indicates that the property is more energy-efficient.

Ultimately, R-value is an important factor to consider when choosing an insulated garage door as it provides better thermal and sound insulation, reduces energy costs, and increases the property value.
