NFRC/CSA Energy Ratings

Enermodal is the leading window simulation laboratory in North America. We have rated the performance of over 50,000 window and door products to the NFRC and CSA performance standards. Enermodal developed the FRAMEplus software, the program referenced in the rating the performance of windows. We are also experts in the use of the WINDOW and THERM window analysis software. 

Our window and door rating services include the following:

  • accredited ratings for U-value, solar heat gain and annual energy to CSA A440.2 and A453, and NFRC 100 and 200
  • design assistance so that windows and doors meet government standards and qualify for utility incentive programs
  • coordination of verification testing for NFRC standards
  • training in the use of window analysis software
  • performance assessment and market research into unique or advanced window systems
