System 55T - 2 1/4" x 4 1/2" Thermal Framing
Marlin has combined excellent thermal performance with a truly versatile storefront/window wall framing system. Featuring a rigid polyurethane "thermal barrier" as an integral part of the extrusions.
System 55 has 2 1/4" x 4 1/2" framing members with glass to the front design. This system is typically glazed from the inside with 1" glazing. However it can be glazed from the outside and will accommodate 1/4" glazing for spandrel locations.
Ribbon or strip window utilize a 2 1/2" x 5" head/sill receptor. Vertical members slip into the receptors and head and sill inserts snap into the receptors to hold mullions in place.
Optional components allow for the integration of entrance doors and vestibule framing.
U-Factors are determined in accordance with NFRC 100.
Glass properties are based on center of glass values and are obtained from PPG Architectural Glass
Overall U-Factor are based on the standard NFRC specimen.
