Architectural Mansard roofs
Architectural Mansard roofs
(OP)
I have a mansard type roof placed on a building - a pitched from soffit to peak type roof but only a certain distance in (versus a complete roof structure) and unfortunately has a plywood interior on steel joists thus combustible. By NFPA standards and NFSA research this does have to be sprinklered BUT how does one calc this space. There is a 7 head clause in NFPA (11.2.3.4.2) BUT there are a few areas where there will be dormers and thus a full attic type calc should be applied.... 2350 ft sq (pitch and dry) on an inline calc just seems overkill. I am contemplating using the Tyco Attics to keep the head calc down and still maintain an attic type calc. Any one come across this and perhaps have a different suggestion?

And all this wood is open inside the attic?? not just a facade?
