Design efficiency

The Exact AluK Bifold Door system is an efficient and cost effective solution to create a modern, tailored solution for your property. Incorporating everything you would expect from high performance bifold doors, the AluK system allows you to open up the space in your home without compromising thermal efficiency across the seasons.

AluK your way

When deciding on bifold doors for your space, there are many considerations. The AluK system allows you to tailor the configuration of your bifolds to fit perfectly within the needs of your project. From the unique flush line pop out handle to the chamfered or square bead options, your bifold doors will slide effortlessly to the right or to the left, with the additional opportunity to opt for split stack on both sides.

The AluK bifold system is fitted with toughened, argon-filled double-glazing with Warm Edge Spacer Bar as standard to achieve optimal temperature control and performance in your Bifold Doors. For enhanced structural integrity, laminated glass is available.

3 standard frame colour combinations are available, with the option for dual and bespoke colours available on request.
