Bi-Folding Doors
We are proud to be one of the very few PVC-U window and door manufacturers that are currently offering you the latest Bi-fold door systems here in the UK.
Welcome to Sustainable Trade Frames Manufacturing
Bi-fold doors are the latest alternative to French doors or sliding patio doors. Our two to seven pane system allows for a wider opening, giving a modern and contemporary feeling to almost any home.
Our Bi-fold doors are made with Kommerling highly durable and low maintenance PVC-U profiles, which is available in a wide variety of colours. The most popular colours include white, Black, Black on white, Grey and Grey on white.
Your Bi-fold doors can open inwards or outwards optimising space where you need it most. We only use high security multipoint locking systems and thermally efficient weather seals to keep the worst of the British weather at bay.
