The 3 Factors of Energy-Efficient Windows

Fall is now in full swing, and, before you know it, it will already be winter. Expect to rely on your HVAC system to keep your home warm. Then again, the rising energy costs throughout the colder months can be tough to handle. At some point, you have to minimize your heating needs, and a timely window replacement helps in this regard.

When tackling this home improvement project, consider replacement units with features that are essential to boosting energy efficiency.

1. Glass

Plain glass for windows or doors offers no protection from the sun’s harmful ultraviolet (UV) rays that cause furniture to fade. Moreover, it doesn’t help the fixture regulate indoor comfort. When shopping for replacement windows, see if the glass has low-emissivity (low-E) coatings. With these, they help prevent the transference of heat, cold and sunlight into the home, increasing your home’s energy efficiency.

2. Glazing

Today’s windows and sliding French doors are equipped with insulated glass units that feature at least two pieces of glass sandwiched together with a thermal spacer. With this configuration, the comfortable, climate-controlled air inside the home won’t escape the outdoors and compromise comfort.

3. Gas

The space between the two pieces of glass is filled with either argon or krypton glass. Both inert gases are denser than air, acting as invisible barriers to ensure better protection against harmful UV rays. These also reduce heat transfer between the glazing layers, preventing condensation. The spacers help create a tight seal to prevent these gases from escaping.
