When winter hits Illinois, your garage becomes one of the biggest sources of heat loss in your home. Whether you use it for parking, storage, or as a workspace, keeping it warm and efficient depends on three key factors: R-Value, U-Factor, and weatherstripping.
Understanding how these work together—and how Haas residential garage doors maximize each—can make a big difference in your comfort and utility bills.
What Is R-Value in a Garage Door?
R-Value measures how well a garage door resists heat flow. The higher the R-Value, the better the insulation.
- Maintain consistent garage temperature
- Reduce energy loss through the largest opening in your home
- Protect vehicles, tools, and stored items from temperature swings
For example, Haas insulated garage doors use polyurethane foam insulation, achieving R-Values up to 16.18 for excellent thermal protection in harsh Midwest winters.
What Is U-Factor and Why Does It Matter?
While R-Value looks at insulation inside the panel, U-Factor measures how much heat transfers through the entire door system—including joints and seals.
- Lower U-Factor = less heat loss.
- It’s the true measure of real-world energy efficiency.
When shopping for a new garage door, look for one that offers both a high R-Value and a low U-Factor for the best performance.
Weatherstripping: The Unsung Hero
Even the best-insulated door won’t perform well without proper weatherstripping. It’s what seals out cold air, moisture, and dirt.
- Bottom seal (astragal) – blocks air under the door.
- Perimeter seals – keep cold out along the sides and top.
- Threshold seal – adds an extra layer on uneven floors.
Inspect your weatherstripping every fall and replace cracked or brittle seals before winter.

How R-Value, U-Factor, and Weatherstripping Work Together
- R-Value is the insulation inside the coat.
- U-Factor is how warm you stay when it’s zipped.
- Weatherstripping is the cuffs and zipper flap that block the wind.
When these three work in harmony, your garage stays warm, energy-efficient, and comfortable—no matter how cold it gets outside.
