Steve is quick to praise the design properties of the door. He said“Aluminium is the perfect material for bifold doors because it has the lightweight strength that’s required. However, the clinical lines of aluminium frames don’t sit comfortably with the PVC-U windows that are used in the majority of the UK’s homes. Integral bifolds solve this problem because they are an aluminium door with PVC-U detailing that’s designed to suite perfectly with leading PVC-U systems. It means homeowners can choose a bifold door that creates the light-filled space they want without having to compromise on the aesthetics. And for installers, Integral is considerably quicker to glaze due to the flexibility and pre-gasket PVC-U beads. The door is already opening up a new level of opportunity for installers.”
