I presented at a meeting this week with Fenestration BC about NAFS 08 and Swing Doors.
There was a very good turn out by our guys as well as numerous other door folks.
We are seeing more interest by the door industry, also we hear some others are getting some doors rated.
So, did you know.
On Dec. 20/2013 the requirement for swing doors to comply to the NAFS 08 standard will be in effect. This means that every exterior swing door will be required to meet the tests for air, water, structural, ease of operation, and others.
This KTC will touch on a few misunderstandings out there.
- ALL exterior doors in a Part 9 residential building must be tested.
- There is an option for limited water performance.
- A limited water rated door must have sufficient protection from weather, with overhang , or in garage, etc.
- A limited water rated door must meet the other requirements for air, structural, ease of operation etc.
- Yes, the door in the garage to house must be rated, but would qualify as a protected door.
- A limited water rated door is water tested with spray but no air pressure difference in to out.
- You could have every door in the house as limited water but they would all need to be protected.
- There is no condition where an exterior door does not need to be tested under NAFS.
- Although folding door systems are not directly covered by NAFS, they are covered by code, they can be tested, and I expect inspectors to look for tested folding doors under what is known as a specialty products category.
Site built doors do not need to meet NAFS requirements. Site built door system definitions are vague and are being better defined shortly. It is expected that a site built door will be a door that is custom built, on site, from non commercially available components. In other words very custom slabs, hardware and jamb designs assembled on site.
- Doors must be tested to the size provided. You cannot qualify at 8’ tall door with a 6’8” tall test.
- Slab types must be tested. You cannot qualify a textured fiberglass slab with a smooth fiberglass test.
- Inswing and outswing designs must be tested, in does not qualify out and vice versa.
Tested door systems must carry a temporary label, and a permanent identification.
I’m working on it, and we will have in place before Dec. 20.
See example of temporary, not yet finalized below.
