Yeah, and don't forget that the fasteners have to be listed for use in seismic zones.

In the building where I work I see the max deflector distance being exceeded by about a foot in some places but because they don't have heat collectors and they are small compartments I know the hot upper layer will move not only horizontally but will build down too fairly quickly and activate the sprinkler. I'm going to tweak the design of heat directors (Kyle and Steve). I envision (2) heavy metal triangles perpendicular to each other, with the base length equal to the deflector distance, installed upside down, the tip a few inches above the head. Using my custom made design fires I'll try to pinpoint when 'the buoyancy exceeds the momentum and the downward flow starts to curl back up' (Roland).
