Contemporary bi-fold doors combine elegance with flexibility, allowing design of panoramic view wide-span door openings to create versatile spaces.
Bi-fold doors are precision engineered to the highest standards and available in a variety of finishes and folding leaf combinations. PVC-U door sashes slide along a thermally-broken aluminium top and bottom track system, designed to ensure years of trouble free service. Rigid aluminium tracks increase the structural strength and enable easy transportation, preventing excessive flex to ensure that the doors run smoothly, even on long spans with multiple leaf configurations. Bi-fold doors are energy efficient and easy to maintain once installed.
Crystal offers a range of colour options and all of these choices are available in dual colour specification, eg Chartwell Green on outside faces and White on inside faces. All colours shown below are a guide. Before making your final decision please ensure you have seen a foil swatch. test
