As per the NAFS requirements, Vinylbilt Windows and Doors products are now being labelled in accordance with the NAFS standard.
What does this mean?
Any window or door that is compliant will have a label on it stating that the product design has been tested to NAFS‐08. These labels indicate four performance requirements:
- Performance Grade (PG)
- Design pressure (DP),
- Water penetration resistance test pressure (water pressure)
- Air infiltration/ex filtration
*The screen shot below shows the calculations for Cambridge Ontario.
If the air infiltration/exfiltration meets NAFS‐08 minimum requirements then it also
meets building code minimum anywhere in Canada. The PG, DP, and pressure
requirements value by location across the country, the CSA A440S1‐09 the Canadian
Supplement to the NAFS‐08 includes calculations to determine the performance
requirement in 679 locations across Canada. These calculations can be quite
involved so Fenestration Canada has developed a web based tool to do these
calculations and made it available online their website to the industry.
ABC Windows Line 1000
Class R – PG30 – Size tested 800 x 1800 mm – Type C
Positive Design Pressure (DP) = 1440 Pa
Negative Design Pressure (DP) = 1440 Pa
Water Penetration Resistance Test Pressure = 220 Pa
Canadian Air Infiltration/Exfiltration = A2 Level
AAMA/WDMA/CSA 101/I.S.2/A440‐08 and A440S1‐09
These calculations can be quite involved so Fenestration Canada has developed a web based tool to do these calculations and made it available online their website to the industry. The web tool can be found at www.fenestrationcanada.ca in the upper right corner of the main page.
