What Are ENERGY STAR Replacement Windows and How Do They Work?

ENERGY STAR Replacement Windows are windows that meet strict energy efficiency guidelines established by the ENERGY STAR program. These windows are designed to reduce heat transfer between indoor and outdoor environments.

To qualify as ENERGY STAR certified windows, products must meet performance requirements related to:

• Thermal insulation performance
• Air leakage resistance
• Solar heat gain control
• Overall energy efficiency ratings

Most ENERGY STAR windows include advanced features such as double pane replacement windows, insulated frames, and Low-E glass coatings.

Low-E coatings reflect heat while still allowing natural light to enter the home. This helps maintain comfortable indoor temperatures during both summer and winter.

Because of these technologies, ENERGY STAR Replacement Windows reduce energy loss and improve overall window insulation solutions.

How ENERGY STAR Windows Improve Energy Efficiency in Washington, DC Homes

Energy efficiency plays a major role in maintaining comfortable homes throughout the year. ENERGY STAR Replacement Windows improve insulation by preventing heat transfer through glass and frames.

These windows reduce energy loss through windows by:
