Easier, More Economical Installation
Two nail fin set-back options, 1” and 1 3/8”, built into the profile as a standard offering, help make installation easier and faster.
No Additional Framing Necessary
Designed to fit into most new construction openings, the three-panel configuration of the Series 3700 requires no additional framing.
Because the interlock is applied after the panel is installed, it can be cut so there are no gaps where unwanted air and light can get in.
