Preperation for NAFS (North American Fenstration Standard) / Energy Star testing

Do you know we are preparing for NAFS (North American Fenstration Standard) / Energy Star testing? 😮
  • This standard is used in Canada and in the United States. It tests and evaluates the performance of windows and doors.
  • NAFS gives windows and doors performance grade in four classes: R, LC, CW and AW (Light Duty, Medium Duty, Heavy Duty and Severe Duty).
  •  NAFS tests ease of operation, air tightness, water tightness, water load resistance, forced entry resistance and duralibility.
  • Energy Star determines U value, Solar heat gain coefficient (SHGC), Air leakage and Energy rating (ER).
