How Energy-Efficient Glass Boosts Home Comfort

With spring quickly approaching and summer right around the corner, it’s important to think about ways to boost your home’s energy efficiency before temperatures outside heat up too much. When it comes to replacement windows and sliding patio doors, investing in high-performance glass can significantly improve your home’s energy efficiency, helping your interior remain comfortable and cool even on hot summer days.

How? By making it easier to maintain your desired temperatures indoors. The sooner your HVAC system reaches your ideal indoor temperature, the sooner you can enjoy comfort inside your home.

In the Winter

Older doors and windows with lower glass temperatures feel colder because more heat is radiated to the door or window from a person’s body. Cold glass creates uncomfortable drafts as well, as air next to the window cools and drops down. This creates a pattern of air movement that not only feels drafty but also accelerates heat loss.

When you have high-performance sliding or French doors and windows with low U-factor ratings, however, you’ll enjoy higher interior door and window temperatures during winter, resulting in greater comfort. Ensuring proper installation and correct weatherstripping will also reduce cold air leakage, improving comfort.

In the Summer

During summer, strong, direct sunlight hits interior surfaces and people, leading to discomfort and overheating. When you have windows with low solar heat gain coefficients, however, they will block out heat from the sun’s rays, reducing your discomfort. Make sure your windows are also equipped with low-emissivity glass coatings and you’ll enjoy heat-blocking benefits without impeding natural light in your home.
