Folding doors open wide spaces, and bring the outdoors in.

The bespoke bottom running hardware components of the 3400-series folding door system have been designed to give maximum carrying capacity, whilst the narrow thermally-broken aluminum profiles offer slim sightlines.

The result? An attractive, high performance bi-fold door.

The 3400-serise folding door comes standard in white, but can be foiled on either the exterior, interior, or both sides to match our windows and patio doors.
