Energy Star Rating

As we face another winter, and with energy prices remaining extremely high, have you considered the amount of heat that escapes through your doors, windows and skylights?  To help you get the most energy-efficient choice materials and products for your home, the NFRC (National Fenestration Rating Council) a third-party, independent, non-profit organization that sponsors certified rating and labeling to help consumers compare the performance of windows, doors, and skylights has developed a non-biased energy performance rating know as Energy Star. This enables consumers to easily identify NFRC-certified products with superior energy performance.

The NFRC label can be found on all Energy Star qualified windows, doors, and skylights and provides performance ratings in five categories, although the Energy Star qualification is only determined by the first two categories.

  • U-Factor measures the rate of heat transfer and tells you how well the window insulates. U-factor values generally range from 0.25 to 1.25 and are measured in Btu/h·ft²·°F. The lower the U-factor, the better the window insulates.
  • Solar Heat Gain Coefficient (SHGC) measures the fraction of solar energy transmitted and tells you how well the product blocks heat caused by sunlight. SHGC is measured on a scale of 0 to 1; values typically range from 0.25 to 0.80. The lower the SHGC, the less solar heat the window transmits.
  • Visible Transmittance (VT) measures the amount of light the window lets through. VT is measured on a scale of 0 to 1; values generally range from 0.20 to 0.80. The higher the VT, the more light you see.
  • Air Leakage (AL) measures the rate at which air passes through joints in the window. AL is measured in cubic feet of air passing through one square foot of window area per minute. The lower the AL value, the less air leakage. Most industry standards and building codes require an AL of 0.3 cf·m/ft².
  • Condensation Resistance measures how well the window resists water build-up. Condensation Resistance is scored on a scale from 0 to 100. The higher the condensation resistance factor, the less build-up the window allows.

Alyssa and Ken did an excellent job and they were a pleasure to deal with. The entire staff did an excellent job and the quality of the work was first rate. We are very pleased with the kitchen remodel.

Since we were so impressed with the service, installation and quality of our sliding door some years ago, we knew we wanted to contact Choice again when we were ready to remodel our kitchen.The entire team at Choice genuinely cared about our project as if it was their own home. Multiple staff members checked in on us during the temporary business shutdown due to COVID-19 which occurred mid-project.It was a pleasure working with Choice and we are very pleased with the results. They made our satisfaction a priority, and we are grateful for the relationships that were built along the way.

Top tier service from Doug, Jason, and Barry. Lonnie in the service department is a respectable guy also.
