Energy Loss Through Your Doors & Windows Costs You Money!

National Fenestration Rating Council (NFRC)

National Fenestration Rating Council - proof of our window's super efficiency and durability rating

Windows and doors are the single biggest source of home energy loss through unwanted heat gain, or heat loss, depending on the season. At a time when energy costs are a major part of your home budget, becoming more energy-efficient is important.

In 1989 Berkeley Lab developed the National Fenestration Rating Council (NFRC), a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors and skylights.

NFRC ratings are fair, accurate, and credible because the rating system is independent – manufacturers have no say over how their products are rated.

That’s why the federal government and energy codes in many states and local jurisdictions encourage homeowners, builders and contractors to purchase only NFRC-rated products.

Proof of Performance - Look for the NFRC Label

Our replacement windows are rated well below the state recommended .40 U-value (U-factor) rating for energy efficiency. The lower the U-value, the greater a window’s resistance to heat flow and the better its insulating value and performance.

Equally important is the window’s solar heat gain coefficient (SHGC). The SHGC is the fraction of available solar heat that successfully passes through a window.

Our windows are top performers because the glass coatings work to block long-wave heat energy (low SHGC) while allowing generous amounts of visible light (high VT) to enter your home. This formulation is ideal in sunny, hot climates.

  • Our windows have a low shading coefficient and U-value which makes our windows more energy-efficient than standard reflective insulating glass.
  • Our windows are designed to allow the interior temperature to remain consistent, providing a more comfortable environment.
  • Our SuperWindow, with the triple pane insulating glass offers low solar transmission and low radiant heat transmission which makes it the perfect choice for our Texas weather.

Let Superior Window Company, show you how our replacement windows exceed the standard for energy efficiency and replacement window value. Realize the full potential of your home with our beautiful and energy-efficient doors and windows.
