Durafold 1000 New Generation Slimline Bi-folds

Bi-folding doors help to create an open, flexible and modern space for both living and working environments, making a real statement of class, elegance and versatility, keeping you warm on the inside in the winter while providing a panoramic view of the outside, and in the summer opening the inside out for the ultimate in luxurious dramatic space ideal for entertaining or pure self indulgence.

The Durafold 1000 Bi-fold door system offers a door designed to bring a graceful elegance to your home, they allow for over a 90% clear opening - bringing the outside in, and are very competitively priced, with slim profiles to minimise frame and maximise the glazing area.

The doors are manufactured using the unique POLYAMIDE thermal break system supplied by SMARTS.

This superior system guarantees excellent performance coupled with unparalleled insulation and excellent long-term reliability.
