Stunning folding design that enhances properties with natural light

Featuring mere frame depths of just 70mm so interiors can be flooded with light, Smart bi-fold doors can be folded to the side to leave a wide open aperture. The perfect solution for bringing the outside in, their stunning, robust design, low maintenance qualities and unique opening makes them a highly attractive addition to any location.

Available in internal and external opening configurations and with a traffic door option, they’re also available with a low threshold option, allowing for ease of access if required.

    Smart Black Aluminium Door

    Innovative design resulting in exceptional performance

    Able to achieve enviously low U-values of just 1.3 W/m²k, the thermal performance of these thermally-broken bi-fold doors is just as impressive as their stylish design. They’re also accredited to standard BS6375-1:2009 for weather performance, which is achieved thanks to EPDM weather gaskets and weather brushes. So, a weather-tight fit is assured wherever they’re fitted.

    However, they excel in terms of security too; the opening sashes are secured by multipoint locking systems and any floating mullions by shoot-bolt locks. Toughened glass is also in use, for extra protection.
