Energy-efficient replacement windows may cost more than traditionally-made ones, but when you consider their long-term benefits, they can be worth investing in. In today’s post, the window and siding contractors at ExteriorPros discuss why energy-efficient windows are the way to go.
What Makes a Window an Energy-Efficient One?
Window energy efficiency works in a larger context when you factor in the walls and exterior walls, all of which form the house’s energy envelope. Proper insulation helps prevent leaks and maintain consistent indoor temperatures. With lower required output from the heating and cooling systems, they won’t consume as much energy, resulting in lower energy bills and prolonged service life.
All parts of the energy envelope have some form of insulation; building and roofing contractors apply fiberglass blankets or expanding foam to the roof, attic, and exterior walls. It’s different with windows because they’re made of glass, a transparent and naturally conductive material, which is why traditional single-pane windows allow heat leaks. The insulated glass in energy-efficient windows feature double or triple panel glass. Separating the interior and exterior surfaces and eliminating air molecules inside helps keep conductivity to a minimum while preserving the function of window glass.
Advantages of Energy-Efficient Replacement Windows
Investing in energy-efficient windows has the following benefits.
- Energy savings — About half of an average household’s energy usage is used on heating and cooling. As described above, energy-efficient replacement windows can help reduce your utility costs while maintaining indoor comfort.
- Prolonged HVAC service life — Lower heating and cooling requirements mean the reduced workload on your heating and cooling systems, which results in prolonged service life and lower maintenance requirements.
- Better natural lighting — Some types of insulated glass feature coatings that block solar heat and UV rays while letting in natural light like clear glass does.
- Sound insulation — A side benefit of energy-efficient windows is they absorb vibration, which means they can help make your home quieter.
