Glass Sections or Windows in Your Garage Door: Is It Worth It?

If you’re looking for a way to enhance your home’s curb appeal, updating your garage door is a great place to start. A garage door with glass windows or an all-glass garage door can add a stylish touch, providing a modern look that can make your home stand out. However, like with any decision, there are trade-offs when adding glass to your garage door. Here’s what you need to know.

What Is The R-Value And U-Value?

R-value and U-value are two terms you’ll often hear when talking about the energy efficiency of a garage door. R-value measures how well your garage door and windows are insulated. The higher the R-value, the better the insulation factor. On the other hand, the U-value tells you how well an insulating glass unit (IGU) will hold in heated or cooled air. The lower the U-value, the better the insulating performance.

Do R-Value And U-Value Work Together?

While lower U-values indicate better insulating performance, higher R-values indicate better thermal resistance. Essentially, the R-value and the U-value work together to provide maximum energy efficiency. When choosing a garage door, it’s essential to strike the right balance between the two. Look for a door with a high R-value and a low U-value to ensure your garage stays well-insulated, regardless of the weather. With the right garage door, you can save money on energy bills and reduce your carbon footprint.

Why Are Glass Doors Less Insulating?

The most significant point of weakness in the glass used for garage doors is thermal bridging. This happens when a conductive material, such as steel, frames the windows. This means that heat energy can quickly transfer from one side of the glass to the other, leading to significant energy loss.

Fortunately, there are ways to improve the energy efficiency of your garage door. Upgrading to a polyurethane-insulated frame is one option. This frame type is designed to minimize thermal bridging, thus reducing energy loss. Additionally, selecting thick, insulated glass panels can make a big difference.

What Should You Look for In a Garage Door with Glass?

If you go for an all-glass garage door, be aware that the insulation value will be much lower than that of a steel, vinyl or fibreglass door. This is because you can’t add additional insulation to the glass like you can to other materials. For instance, Wayne Dalton’s Model 8800 has an R-value between three and 4.5. Therefore, you can expect some heat loss.

However, if you’re worried about the insulation value because you live in a cold climate, opting for a garage door with window inserts will give you a much higher insulation value while still providing visual impact. For example, Wayne Dalton’s Model 8700 vinyl garage door offers an R-value of 11.75 and can accommodate many glazing options.
