Thermal Storefront System FL300T

Energy Efficient Thermal Storefronts for Commercial Buildings

FL300T Storefront System

Series FL300T thermal 2″ x 4-1/2″ center set storefront framing systems for 1″ glass is designed for low-rise applications. Enhanced thermal performance is achieved using thermal break construction in response to increased demands for energy efficient commercial buildings. Snap-together profiles using integral screw-spline joinery allows for the frames to be pre-assembled in panels resulting in increased productivity and quality control. Perimeter profiles with full-depth pockets eliminate the need for filler plates and provide direct anchoring to the substrate with excellent water control.
