Luminia F82 Plus Bifold Door

Closed aluminium bifold door

Bring the outside in and keep the weather out with the contemporary Luminia F82 bifold door

The Luminia F82 Plus bifold door has been designed with style and performance front of mind. It cleverly combines the intimacy of inside spaces with the freedom of outside living, without ever compromising on performance, safety or security.

And like all AluK aluminium window and door systems, it continues to push the industry forward by delivering unrivalled innovation and installation simplicity.

For starters, it delivers an industry-best 1.3 U-value thermal performance for double-glazed units and 0.9 U-value for triple glazed, keeping your home warm and comfortable.

The F82 bifold door boasts contemporary flush hardware, while the elegant slimmer symmetrical sightlines of the frame and panels provide larger glazing area than others on the market, flooding the home with more natural light.


Outside space has never been more important and appreciated, and installing bifold doors gives you the opportunity to enjoy your view and create a seamless link between your home and garden. With greater glazing areas and the desirable slimmer sightlines that the F82 is renowned for, you can flood your rooms with more natural light.

Multiple doors can be combined with open-in or open-out options in a variety of styles to create a wide expanse of opening, while HD rollers allow for 3000mm wide bifold doors in three panes for the ultimate panoramic view.

Open up an entire corner or your room with the floating corner which offers you uninterrupted views of your garden space with the same smooth operation, total security and unrivalled weather performance that you’d expect from the unique F82.
