What Is garage door R-Value

When diving into the world of garage doors, one term you might come across is the “R-Value.” Not a mere jargon, this term plays an integral role in defining the efficiency of your garage door. So, what is it all about?

Understanding R-Value

The R-Value is a measure of thermal resistance used in the building and construction industry. In simpler terms, it indicates how well a material resists the conductive flow of heat. When applied to garage doors, a higher R-Value signifies better insulation properties, ensuring your garage remains comfortable throughout the year.

Importance of Garage Door R-Value

For many homeowners, the garage serves multiple purposes. Besides housing vehicles, it might be a workshop, gym, or even an extended living space. Hence, an energy-efficient door can:

  • Save on energy bills.
  • Maintain a consistent temperature inside the garage.
  • Reduce noise pollution.
  • Increase the overall life of the garage door.
