With their concertina design timber bifold doors allow the creation of a clear opening, providing a seamless connection with the outside. With the option of inward and outward opening doors, our designs can be configured to work exactly as the space requires.
A low profile aluminium threshold provides a smooth transition between the interior and exterior spaces. The incorporation of weather seals on the door leaves and within the track ensure that all parts of the door are well sealed, providing excellent protection from the elements. A low resistance, easy to adjust sliding mechanism provides effortless opening and closing.
All of our timber 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.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that George Barnsdale & Sons Ltd is consulted before specifying.
