U-Factor defines the amount of heat loss through the total unit in BTU/hr*ft 2*◦F, metric in W/m2*K. The lower the value, the less the heat is lost through the entire product.
2
Solar Heat Gain Coefficient (SHGC defines the fraction of solar radiation admitted through the glass both directly transmitted and absorbed and subsequently released inward. The lower the value, the less heat is transmitted
through the product.
3
Visible Transmittance (VT) measures how much light comes through a product (glass and frame). The higher the value, from 0 to 1, the more daylight the product lets in over the product's total unit area. Visible Transmittance is
measured over the 380 to 760 nanometer portion of the solar spectrum.
NFRC ratings are based on modeling by a third party agency as validated by an independent test lab in compliance with NFRC program and procedural requirements.
This data is accurate as of February 11, 2013 and revised August 28, 2013. Due to ongoing product changes, updated test results or new industry standards or requirements, this data may changeover time. Due to variations in
dealer and distributor inventory levels, products that were manufactured before February 11, 2013 that were designed, tested and labeled with different NFRC values may still be available. Check the labels on the product
packaging to confirm NFRC values. Ratings are for sizes specified by NFRC for testing and certification. Ratings may vary depending on use of tempered glass, different grille options, glass for high altitude, etc.
For NFRC certified total unit performance for units with capillary breather tubes, please refer to the High Altitude information section for each unit.
This document provides NFRC certified U-Factor, Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT) values for Andersen® products
along with the corresponding ENERGY STAR® Version 5.0 (2010) climate zones that the product and glass type meet.
These products rated, certified and labeled y National Fenestration Rating Council® (NFRC) - a non-profit organization that provides fair,
accurate and credible energy performance ratings for windows and doors.
Many of our products meet the stringent energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S.
Department of Energy. These guidelines are based on the heat gain and loss of each product in various regions of the country. Check the
Andersen product performance available at www.andersenwindows.com for specific ENERGY STAR qualifications.
