Description

The Altherm bi-fold system offers formats that can stack to one or both sides. Corners are square-cut for optimum strength and aesthetics and the track is within the frame for direct window support.

A wide range of configurations are available including 'lay-back' arrangements in 2-panel formats that allow the bi-folds to swing back against adjoining walls for the clearing of decks. A brush seal at the frame head protects against the entry of rainwater.

For best overall performance, pair with The AGP System® with Solux-E® or Solux Ultra® low-e glass.
