The BSF70 HI System is the next generation of Bi-folding Doors and gives maximum control over the style and operation of the doors. Multiple panels can be added to accommodate the unique design specifications of the building, with the option to open-in or out as required. The system’s narrow profile ensures that maximum glazing is achieved, flooding spaces with natural light. Glazing Bi-folding Doors is a task that can vary in complexity depending on experience, glazing type and thickness and even cold weather can be a contributing factor. Our new Quik Clip bead takes just seconds to clip securely into place, with no need for force or special tools, and it doesn’t impact on the sight-lines of the door. To see how easy it is to glaze each panel using the new ‘Quik Clip’ bead please view our videos in the Technical Videos section below.

The BSF70 HI offers superb air, water and wind resistance, with exceptional test results, which gives you peace of mind that this durable door can withstand the extremes of British weather. Security is assured with full PAS 24 security accreditation, which also ensures that the BSF70 HI can be fitted in new build projects which require compliance with Part L. With U-values of 1.4 double and 1.1 triple, this door is an energy-efficient option for both new build and refurbishment projects.
