The National Fenestration Rating Council (NFRC) is in the process of launching a pilot program for the new LEAFF methodology for simulating the thermal performance of windows, doors, and skylights. The current NFRC methodology requires modelling each individual product option for NFRC certification, which could potentially add up to 20-100 glass and frame combinations. By contrast, the new methodology only requires simulating 3 individual product options in each category and then uses a trendline approach based on the centre-of-glass U-factor to calculate the thermal performance of different product options within that trendline category.

NFRC sees two major benefits of the new LEAFF methodology, the possible reduction in the number of options that will be simulated and a streamlined method that may allow manufacturers to get their new and innovated products to the market quicker. In this webinar, learn about the new LEAFF methodology, the IGU and frame characteristics that determine the trendline categories, and the potential implications for future NFRC-certified products.
