High performance bifold door installations In Bristol, Bath, and surrounding areas

Designed to meet your specific project requirements, we supply and install premium Smart Systems aluminium bifold doors, Composite Doors, Residence Doors, Entrance Doors, French Doors and Stable Doors. Featuring an innovative concertina fold, bewitching bifold doors slide and fold back on themselves to open up entire walls with ease. Able to deliver the sleekest sightlines whilst remaining super-stable and robust, their excellent corrosion-resistant qualities work well in coastal locations in the South West too.

Available with high quality aluminium frames with an extended polyamide thermal break and advanced double or triple glazing, aluminium bi-folds are often the first choice for opening up tight, cramped spaces and enhancing minimalist industrial architectural stylings.
