Understanding Energy Efficiency in Windows

Energy-efficient windows keep your home cooler in summer and warmer in winter. They use advanced materials and design to block temperature changes from outside. Key factors in window energy efficiency include:

  • U-factor: Measures how well a window insulates (lower is better)
  • Solar Heat Gain Coefficient (SHGC): Shows how well a window blocks heat from sunlight (lower is better for warm climates)
  • Air leakage: Measures how much air enters through the window (lower is better)
  • Visible Transmittance (VT): Measures how much light passes through the window

At ARDMOR, we pick windows that do well in these areas. This ensures our customers get the best energy-saving technology.
