SF85 Bi-folding Doors

SF85 Slim Bifolds:
do more with less

SF85 Sliding Folding Doors are one of the slimmest bi-folding doors currently in the UK – beating most of the top brands with the door mullions of only 105mm when the door panels are closed.

On top of that, with each panel of up to 1.5 metres wide and up to 4 metres high, the SF85 Bi-folding Doors can create a three panel bifolds where many other systems must use four panels. As a result, you can create bifold doors with fewer panels, cheaper in price and offering better views than four panel models.

This world-class highly insulated sliding-folding door system glides smoothly thanks to the effortless bottom rail operation, and combines minimal aesthetics with an outstanding performance.

Flexible design choices (i.e. odd and even number of door leaves, corner configuration and semi-structural versions) provide numerous options to meet your requirements in a very effective and elegant way.
