Everything you need to know about the SUNFLEX SF35 Slide-and-Turn System 

Best Views - Day Or Night - Rain Or Sunshine


The Sunflex SF35 double glazed slide and turn system offers slim non-thermal aluminium interlocking frames to emphasise your view with only slender aluminium edges. The double glazing not only helps add an additional thermal support it also improves the sound insulation.

An ideal product for all year round, keeping away the worst of the winter weather when used externally. During the summer months it can be opened completely to make the most of these precious times.This style of door has a single track and offers a single panel opening with then the ability to slide and stack all the remaining panels open. With slide and turn systems the panels are easily slid open around corners if required, with all panels stacking to one or both sides.

A double glazed SF35 surrounding the top of your balcony wall not only helps to keep out the cold wind and rain. But also reduces the surrounding noise making the balcony feel more part of your home. This enclosure can then be completely opened up to take advantage of those warmer times.
