- NAFS gives windows and doors performance grade in four classes: R, LC, CW and AW (Light Duty, Medium Duty, Heavy Duty and Severe Duty).
- Â NAFS tests ease of operation, air tightness, water tightness, water load resistance, forced entry resistance and duralibility.
- Thermall modelling determines U value, Solar heat gain coefficient (SHGC), Air leakage and Energy rating (ER).
