Glass Partitions & Moveable Walls
The SUNFLEX range of high-quality internal glass partitions have been installed across the UK for the past 25 years.
For those considering an open plan living space as part of an extension, renovation or new-build home SUNFLEX UK has a range of internal bifold, sliding, slide & turn or moveable wall systems that can be used to divide up the space if required.
The range of systems, configuration and design options allows you to enjoy the open plan feel but with the ability to close the space off when required. Available in framed or frameless systems, in single or double glazing and as top hung or bottom running doors there is an option for every requirement; whether you are seeking a bit of privacy, sound reduction, additional level of thermal performance or security.

SF20 Frameless sliding doors
Frameless single glazed sliding door on a multi-track from a single panel sliding on an extended track to 12 panels all sliding.
A subtle bottom track only 11mm deep can be recessed into the floor for a flush finish. The sliding option provides wider panels; as they stay in the track, this does not encroach into either room. Extended track available which would provide a 100% clear opening.

Perfectly suited for the renovation of period properties or for adding character to new-build extensions and home renovations the SF22 Heritage can be easily retrofitted and combines the Art Deco style with contemporary performance and usability.

SF25 Top running frameless slide & turn doors
This innovative top-running, frameless slide and turn door provides a stylish, minimalist appearance when closed.
The single glazed system offers a stylish option for those seeking to divide up open-plan spaces and consists of individual, non-connected panels that slide on a single track to one end of the opening before stacking neatly at 90 degrees from the track, to create a completely unobstructed opening.
Brochure Technical -
SF30 Bottom running frameless slide & turn doors
Similar to the SF25, this has a frameless slide and turn. However, it is bottom running enabling larger panels and making it suitable for more openings.
Each panel stacks open 90 degrees to the track, providing a wider opening. This creates the opening where you need it as the panels are not joined together. All panels can open around a corner with all panels stacking at one side.
Brochure Technical -
SF35 Framed slide & turn doors
A better seal between panels and double glazed; this provides an extra level of sound insulation and thermal performance if required.
Each panel stacks open 90 degrees to the track, providing a wider opening. This creates the opening where you need it as the panels are not joined together. All panels can open around a corner with all panels stacking at one side.

SF45 Internal bifold doors
Aluminium slimline bifold designed for internal use, preventing you from paying extra for a thermally broken system.
Slim sight line of 117mm and only 55mm front to back. Each panel is hinged together creating a better seal. The glass can have integrated Venetian blinds providing privacy or protection from sun glare when you need it along with unobstructed views. Matches in very well with the Sunflex SF55i bifold if you are having that externally.

Garden Rooms
While primarily utilised as internal glazed partitions, the SUNFLEX range of frameless sliding and slide and turn doors offer a highly versatile option for those seeking to create a winter garden or garden room.
The systems have been designed to integrate with the SUNFLEX range of patio terrace roofs, enabling you to enclose your patio to keep out wind and rain and extend your living space later into the summer evenings and for longer periods throughout the year.
Balcony glazing
Whether included as part of the design of an apartment complex or retrofitted on to existing balconies, the SUNFLEX range of sliding or slide and turn doors offer a clever solution for wrapping around a balcony to provide protection from the elements.
By offering protection from wind and rain the doors allow the balcony to be used for more of the year and creating an extra little bit of living space.
