About Invisi Fold Windows

The ENFOLD System is designed to convert standard welded windows & doors into sliding/folding/swing systems. ENFOLD is a unique alternative for 'concertina' 'fold & slide' or 'bi-fold' windows & doors which is based on movement of individual panels. It can be manufactured with invisible hinges showing only 1 or 2 handles (depending on style) also it can be manufactured alternatively with face mounted and fully adjustable 3D hinges. ENFOLD sliding panels are bottom loaded and will 'NOT' drop like conventional 'fold & slide' systems resulting in trouble free installations.
