UPVC Bifold Doors

Premium quality uPVC Bi-folding Doors designed & manufactured in the UK

Like our aluminium bi-folding door, our uPVC timber alternative bifold will satisfy your desire for more light and space and offers a stylish link to the world outside, spanning up to 6 metres. When it came to developing our own uPVC bi-folding door, we specified that the suite of profiles must be purpose-designed for the job and that is why we believe we offer the ‘best of bifolds’, with slim sightlines, dedicated accessories and durable, trouble-free performance.
