BOOST YOUR MOOD WITH UNINTERUPTED VIEWS
Multiple panels can be added to accommodate the unique design specifications of the house, with the option to open-in or out as required. The system’s narrow profiles ensures that maximum glazing is achieved, flooding spaces with natural light.
With a floating mullion frame, the BSF70 HI bifold door can be opened up completely on two sides to enjoy uninterrupted views of your outside space.
The innovative, flush line pop-out handle allows panels to stack flush when they are fully open, adding to the sense of openness that can be achieved.
AT A GLANCE:
In addition to the inherent strength of aluminium, the BSF70 HI combines security hinges and locking mechanisms with a unique heavy-duty roller design to provide the security and reliability demanded in high traffic applications. The system also incorporates a pop out T-handle design that allows for square flush stacking panels when doors are fully open.
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.

“Opening out, the BSF70 panes are tucked away when they are open and give me a much bigger, more sociable space to entertain and relax. I looked at other options, but the bi-fold made perfect use of the space and gave me the contemporary look and feel I wanted.”

“As property developers, we have worked with MGP Windows on many occasions in the past and knew that their AluK doors would be our first choice for this project. The finished result is stunning and has given the property yet more wow factor.”
