FIRST™ bi-fold windows run on an easy-slide track system and allow wide opening. They’re ideal where homeowners or designers want to capitalise on views, capture summer breezes, or create a unity between indoors and outdoors. Because bi-folds project outwards exercise caution in using them beside decks or walkways.
Configurations with even numbered panels are generally used, eg. 2 panels, 2+2 panels, 4 panels and 6 panels.
