Dekko’s trade guide to aluminium bifold doors

Using intelligent profile design, aluminium bifold doors capture the very best in market-leading design and technology and are incredibly popular amongst modern UK homeowners.

Fitted as an internal room divider, a back door to the garden, or to give a period property a modern twist, aluminium bifold doors for trade add a touch of sophistication while also keeping properties protected thanks to anti-finger locking technology, durable materials, and excellent safety measures.

What are the features of aluminium
bi-fold doors?


  • Efficient– Fit flush against the edge of the doorway for unobstructed views.

At Dekko, we offer two market-leading bi-fold door ranges: The Räum range, and the Decalu 88 bi-fold.

Smooth functioning Räum aluminium bifolds

Räum bifolds are made from the highest quality aluminium profile and are available in two aluminium systems. Räum Gleiten 68 is the more cost-effective option and is available with between 2 and 7 opening panels with a maximum opening width of 7m. Räum Gleiten 77 is the premium bifold door choice.

The windows look fantastic

"Recently used Dekko Windows to supply the windows and aluminium bi-fold doors for our renovation project. We paid a short visit to their showroom where Rob and Neil were really helpful, showing us around and providing options for us. We were really happy with the whole process and the windows look fantastic. Would definitely recommend this company."
