Fabrication
There are two common fabrication and erection methods for installing storefront systems, including the screw spline and shear block methods. Both methods allow glazing contractors to conveniently preassemble single units in their shop environment or at the job site.

The screw spline method utilizes mating mullions during the fabrication process to attach sidelite horizontal glass stops with screw spline door jambs. Horizontal glass stops should be cut for daylight openings below 1/32 inch, while vertical door jambs should be cut longer because they run all the way from the top of the storefront to the floor. When assembling screws on vertical members, use drill jigs to drill holes.

Once all material is cut, the sill, head and horizontal ...
... members must be buttered (bead of caulking on the raw edge of the profile) at the edges before assembling the storefront. This, along with installing water diverters at the intersection of the vertical jamb to the horizontal members, and adding end dams to the sill flashing, will prevent water infiltration when the storefront is sealed and installed.

Shear block storefront systems, also known as can systems, use shear blocks to assemble storefront units at the top openings of sill flashings. Typically, once shear block systems are assembled, they are stacked in place at the job site. With this method, all end dams must be buttered on the head and sill cans to ensure protection against water infiltration. Be sure that the horizontal locations are caulked at the shear block locations to ensure a water tight seal, which will essentially block water from penetrating the substrates and leaking into the building.
