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 bifold 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, bifold 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.
