Elegant, stylish and secure
With their concertina design, timber bifold doors allow the creation of a clear opening which provides a seamless connection with the outside.
A low-profile aluminium threshold provides a smooth transition between the interior and exterior spaces. In addition, we incorporate weather seals on the door leaves and within the track which ensures that all parts of the door are well sealed, thus providing excellent protection from the elements. A low resistance, easy-to-adjust sliding mechanism provides effortless opening and closing whatever size bifolds you go for.
All of our wooden bifold door designs are provided with high levels of customisation with a choice of glazing, paints and stains and the option of dual colour. Double and triple glazing is available, with some designs allowing acoustic laminates for exceptional performance.

The system we have developed is designed to overcome the challenge of hanging heavy weights from timber beams which can cause deflection and prevent the doors from opening properly.
The bottom-hung design will overcome this by transferring the weight to the floor with a special bottom-rolling mechanism in place of the traditional top-roller function.
