Outswing French Door

One or two hinged leaves swing outward, so wind pressure pushes each leaf harder into its seals.

Best for: The door used every day, and the primary egress door on the most exposed side of a coastal house.

Hover the drawing to see how it opens.

Overview

Where a slider is the wall that moves, a French door is the door you use every day. The 150 Series section and multi-point hardware give it the highest tested design pressure of any Fortwell system, which is why it is specified on exposed elevations and as the primary egress door in coastal houses. It swings out so wind load pushes the leaf into its seals.

Design PressureThe wind load a unit is tested to hold, in pounds per square foot.

U-FactorHow much heat passes through the whole unit — lower is better.
0.32 – 0.50
STCSound Transmission Class — higher numbers mean a quieter room.
