Bifolds are a great way to extend your living space in the summer by giving you an unobstructed opening to any outdoor living and entertainment areas allowing a greater sense of indoor-outdoor living.
Where you have an uneven number of panels, it is a good idea to include a hinged door. This allows convenient exit or entry without opening up the entire Bifold.
Bifolds are available as standard or in a Inline version, which folds back flush with the exterior cladding.
Maximum sizes for bi-fold doors vary by width, height, wind zone, and glazing requirement. Your local Bradnam's branch will be able to advise you whether a configuration is possible or contact NALCO Technical support.
As a guide, bi-fold panels up to 2.2m high by 0.85m wide are recommended.
An Aluvent passive ventilator enables passive ventilation to be included into all bi-fold doors. Refer to the Aluvent section.
A standard range of flashings include 95mm, 84mm,71mm, 68mm, 63mm, 58mm, 53mm, 48mm, 45mm, 41mm, 38mm, 31mm, 25mm and 14mm. These have been designed to comply with E2/AS1 Amendment 6 requirements. Refer to the flashings section.
Proprietary FANALCO bi-fold hinge and bi-fold roller assemblies are critical components to provide attractive visual and functional performance of doors and windows. Refer to the hardware section.
