6 points of energy efficient windows

  1. Our vinyl frames are virtually maintenance free and made from extruded vinyl offering greater duraility, strength, thermal insulation, and corrosion resistance than traditional aluminum frames.
  2. Inert Argon or Krypton gas is filled in each glass unit cavity.  These harmless gases provide superior insulation capability against the transfer of head or cold from the outside.
  3. Suspended coated film glass packages exceed all the insulation characteristics of triple pane glass without and of the design limitations and weight issues typical of triple-pane glass systems.
  4. Low-E glass coatings are applied to the film and/or glass to keep winter warmth in and summer heat out.
  5. SeriousWindows 501 Series features a warm edge spacer system that reduces condensation and improves thermal efficiency.
  6. The combination of the thermal coatings, suspended coated film, insulating gases and a warm edge spacer system create unique, high performing glass packages that are designed for your specific home and climate
