AAMA & NFRC Certification Requirements / Test Summaries

 







AAMA/NWWDA 101/I.S.2-97

Since 1962, AAMA's (American Architectural Manufacturers Association) ANSI-accredited Certification Program - the original third-party window performance verification program - has provided manufacturers with the means to independently demonstrate product performance quality to their customers. The AAMA's Certification Label on a product tells customers that it has been verified as conforming to AAMA's standard requirements through independent laboratory testing and follow-up on-site inspection of the manufacturer's product line.

The Tru-Frame Vinyl Greenhouse Window meets and/or exceeds all the requirements of AAMA/NWWDA 101/I.S.2-97 and is certified by AAMA up to the size tested below.

NFRC 100-97 Thermal Performance Test Report

National Fenestration Rating Council (NFRC) is a non-profit, public/private organization created by the window, door and skylight industry. It is comprised of manufacturers, suppliers, builders, architects and designers, specifiers, code officials, utilities and government agencies. NFRC provides consistent ratings on window, door and skylight products. NFRC's primary goal is to provide accurate information to measure and compare the energy performance of window, door, and skylight products.

Series/Model: "K"
Type: Poly Vinyl Chloride (PVC) Garden Window
Size Tested: 76" wide by 46 " high
Glass Type: Insulating glass w/swiggle spacer system.Low-E coating on all #2 surfaces of insulating glass.

Test Results: Standardized U-Factor (Ust) 0.79 Btu/hrft2F (Area Weighted)

U-Factor.measures how well a product prevents heat from escaping. U-Factor ratings generally fall between 0.20 & 1.20. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value.

Test Results Summary: Solar Heat Gain Coefficient: Testing N/A for Projected Units

Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits.

Test Results: Visible Transmittance (VT): Testing N/A for Projected Units

Visible Transmittance (VT) measures how much light comes through a product. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.

Test Results: Air Leakage (AL): 0.11cfm/ft2

Air Leakage (AL) is indicated by an air leakage rating expressed as the equivalent cubic feet of air passing through a square foot of window area (cfm/sq. ft.). Heat loss and gain occur by infiltration through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly.
