Bespoke Aluminium Bifolding Doors

Aluminium bi-fold doors are the best product on the market for opening homes to the garden and merging indoor and outdoor spaces. And homeowners have taken notice. According the recent Palmer Market report, aluminium is tipped for further growth going forward. This gives window and door installers a big opportunity to take advantage of this growing market by adding aluminium bi-fold doors to their product range.

We manufacture the SAPA Crown Bifold doors system which is ordered immediately after payment has been received.  This helps to reduce inventory whilst improving scheduling and minimising disruption of production.  To see how SAPA handle your order, please click on the video.

New CNC machinary is currenly on order and is due to be installed in March 2019. This will allow us to handle urgent orders by cutting and manufacturing bifold doors from stock.


You can now price your aluminium door using our online pricing tool below.  You can also specify specific RAL colours for the inside or outside frame, which is reflected on your visual representation. Send a copy to your mailbox to order at a later date.

Aluminium Bifold Door Gallery

Very popular with its unique Shootbolt & 'D' Handle and continuous hinges. The innovative hinge means that there are no bulky or unsightly hinges to disrupt the contemporary sightlines. The door features hardware designed specifically for doors - as opposed to 'window' hardware utilised on some doors of this type. This allows the Crown Bifold Door to not only be securely locked but also used as a main entry or exit operable from both inside and outside, using our robust & secure Multi-Point Lock.
