Everything you need to know about the SUNFLEX SF25 All-Glass Slide-and-Turn System (Glass Curtains)

Enjoy Your Outdoor Spaces Without Compromising Your View


The Sunflex SF25 slide and turn system’s timeless design makes it suitable for outside enclosures, such as balconies, terraces and patios.

Alternatively it can be used to create a flexible, contemporary and useable open space internally as room dividers for both living and working environments.
The first opening panel acts as a single access point, each individual panel then slides independently back across to the same side to stack. This allows you to have as much or as little of the glass wall open at any one time. The system can open to the inside or outside and stack to the left or the right or split to stack on both sides. The single in-line running track caters for a wide range of applications. This allows the glass panels to slide from 90° to any angle change up to 180°, including segmented curved radius openings.
An ideal product for all year round, keeping away the worst of the winter weather with minimum impact on a building’s design and during the summer months can be opened completely to make the most of these precious times.
