Timber Bi-fold Doors

With their concertina design, timber bi-fold doors allow to create a clear opening which provides a seamless connection from the inside to outside. A low resistance, easily adjustable sliding mechanism provides effortless operation whatever size bi-folds you choose.

All our timber bifold door designs are provided with a range of customisation options, a huge choice of glazing, paints and stains and the option of dual colour as well. Double and triple glazing is available, with some designs allowing acoustic laminates for exceptional performance.

QBD use the industry leading George Barnsdale for our timber bi-fold doors, they have been manufacturing wooden doors at their Lincolnshire-based factory since 1884. Both George Barnsdale & QBD’s commitment to quality, beauty and performance has always been at the forefront of what we do.

By selecting only premium materials and using an advanced coating system, our timber sliding doors will continue to look good, with minimal maintenance, year after year. For peace of mind, we offer industry-leading, manufacturer-backed guarantees.

With U values as low as 0.9 W/m2K using triple glazing and 1.3 W/m2K as standard with double glazed units, you can guarantee these doors will improve your living space by improving the thermal insulation within your property.

Our low profile aluminium threshold provides a smooth transition between the inside & outside spaces. In addition, we incorporate weather seals on the door leaves and within the track that ensures all parts of the door are sealed, providing excellent protection from the elements.
