|
Marlin
storefront framing systems feature heavy wall (.080), rugged aluminum
extrusions. Appearance and durability make Marlin the ideal choice for
storefront performance.
Unitized
assembly saves fabrication and installation time. This screw spline method
utilizes two piece snap together vertical mullions, so the storefront arrives
assembled at the jobsite ready to install.
System 45 has
2" x 4 1/2" frame members that are flush glazed with 1" insulating glass or
panels. A glazing adaptor is available to accept 1/4" glazing if required.
System 45
offers door jambs, headers and thresholds to accept any narrow, medium or wide
stile aluminum entrance package. Also available are 4 1/2" x 4 1/2" corner
mullion, sill flashing and head compensation channel for header deflection.
