altherm™ doors / bi-fold

Sweeping views and welcome breezes can be yours with wide opening Altherm™ bi-folding doors. Altherm™ has a smooth running and reliable bi-fold system that copes easily with a large opening span.

The ultimate in clear decks is possible with the ultra-convenient ‘lay-back’ bi-fold where the doors swing back against adjoining walls. They don’t project out and potentially obstruct decks and walkways (available in 2-panel, 2+1 and 2+2 configurations).
