CURB INSTALLATION
|
|
The
manufacturer recommends that only one-piece roof curbs be used with SSR
roof systems. The roof curb will be installed under the roof
panels on the upslope end and over the panels at the downslope end. To
accomplish this, the roof panels must be endlapped at the downslope end
of the curb. This allows both ends of the curb to shed water and places
the heavier gauge metal of the curb under the roof panels for better
resistance to foot traffic. The exception is at the downslope end where
the curb is on top of the roof panels. Since there are endlaps at this
area, back-up plates provide support. Cinch straps (18 gauge Galvalume®)
furnished by the curb manufacturer are used at the top and sides of the
curb to form a compression seal.
Inside cap cells (for top) and outside cap cells (for bottom) are used to seal the panel trapezoid to the roof curb. If curb placement is not critical (within 12"), the cap cells may be factory attached to the curb. If the curb must be located in a precise location, order the cap cells loose for field installation. For the purpose of these instructions, a curb with factory attached cap cells is illustrated. |
