Aluminium Bifold Doors

SDB Aluminium bi-fold doors are German-designed and manufactured to the highest specifications and industry standards. Precision engineered, these doors will enhance the appearance of any property, regardless of age or style, and will provide excellent thermal efficiency.

Style Choices

Bi-fold doors can be inward or outward stacking, and they can fold to the left, to the right or split in two. Bespoke doors are available but we also offer a choice of standard set sizes.


All the doors we supply either meet or exceed police and BSI Kite Mark recommendations. The glass is toughened while the doors feature multi-point shoot bolts which lock into the frames. Our bi-fold doors will allow you to feel secure in your home.

Weather Resistance

The doors and frames have multi-layered weather seals, while the floor track allows the doors to withstand even the worst of the weather.

Energy Performance

All our doors exceed current building regulation requirements. They are manufactured with thermal barriers between components, weather seals and high-performance glass sealed units which reflect heat back into the indoors. We also offer a selection of glazing options for enhanced sound and heat insulation.

Other glazing options include Pilkington self-cleaning Activ glass, solar reflective for South facing doors and even triple glazing for enhanced sound and heat insulation. Discuss these options with your friendly surveyor.

Frame Finish

Four standard finishes are available, at no additional cost: GLOSS WHITE RAL 9016, MATT WHITE RAL 9010, MATT GREY 7015M and BLACK RAL 9005. If you want a bespoke colour then you can choose one from over 200 colours in the RAL chart.
