When purchasing a new garage door or replacing an old one, there are several factors to consider, such as the design, the R-value, the quality of the materials used, etc. The R-value is significant because it determines how well the door will keep the garage comfortable in hot and cold weather. Garage doors are made of small metals that usually allow heat to flow in and out.
The Basics of R-Value
The R-value denotes the resistance to heat flow. It is the measure of how well the garage is insulated. Products with higher R-values are better insulated, allowing less hot or cold air transfer. The thickness and physical properties of the insulator, which is often made of polystyrene or polyurethane, are the most commonly used methods for determining R-value. These figures are usually between zero and twenty.
Difference between Polystyrene and polyurethane Insulation
Because of its affordability and ease of installation, polystyrene is utilized more frequently. It is produced in large sheets or panels that can be easily shaped to fit any garage door. The spray foam form of polyurethane is more expensive than polystyrene, but more advantageous. R-values for polystyrene range from R1 to R10, whereas those for polyurethane are between R10 and R16.
Suitable R-Values for Garage Doors
The kind of garage you have and the time you spend there will both play a significant role in determining the R-value of your garage door. In general, detached or independent garages cause a lower R-value ranging from R-0 to R-6. Whereas garage doors with values ranging from R-6 to R-9 are recommended for attached garages that are not constantly cooled or heated, they provide adequate insulation and protect the objects stored in the garage from damage.
To save energy costs, doors with an R-value of R-13 or higher should be used in garages that are constantly warmed or cooled. For professional advice and consultation, contact Environmental Door at 616-453-0614. We provide R-value statistics to help you decide which garage door is best for you.
R-Value Variation Depending on the Garage Door Material
Different door products provide varying levels of insulation. Polyurethane and polystyrene are the two plastics that are often utilized. Despite being typically molded to fit door frames, polystyrene does not provide complete coverage and allows heat to escape. Polyurethane is preferable; it is often poured into the panels to fit and fill the entire space. It also prevents air leakage, offers superior insulation, and reinforces the door’s structural integrity.
The Importance of a Garage Door with Good R-Value
The primary reason for installing a garage door with a high R-value is to control heat distribution in the home. The following are the benefits of having a garage door with a high R-value:
- A garage door with a high R-value help reduce the adverse air transference that causes extreme hot or cold temperatures in your garage.
- Choosing a high-quality garage door product can significantly reduce your home’s utility bills. The amount of energy lost for heating and cooling through your garage door will also be reduced.
- Installing a garage door with a high R-value that can maintain stable temperatures improves the comfort of your garage and ensures the safety of your automobile and stored materials, including automotive fluids. A garage door with an R-value of at least 16 should be used for adapted facilities such as the home, office, and gym.
The R-value of a garage door varies depending on the environment and other factors; however, if you want to keep your house cool during summer and warm during winter, you should choose a garage door with a high R-value. Because of their high R-values, fiberglass and vinyl doors are excellent garage door options.
