Classic sun and wind awning

Discover SL400: the retractable side wind and sun awning with interesting extras. Perfect for maintaining privacy and protecting terraces, balconies and outdoor entertaining areas from the sun and wind. Also ideal as side protection with a sun canopy.

Tension spring in quality aluminium

This wind screen opens easily with a pull rod made of quality aluminium. SL400 offers effective wind protection and creates a comfortable, enclosed outdoor area for guaranteed privacy and an extended outdoor season.

Including child lock

The screen stays taut due to a spiral spring and hydraulic brake. With manual operation, a ‘Soft Close’ system for supple closing, child lock and a spring in the fabric roll, the SL400 is a safe choice.

Why natural cooling

Our mission statement, “We Believe in Natural Cooling,” lies at the heart of all our efforts. We consider smart solar shading to be the most natural and energy-efficient way to block heat. Compare it to a tree providing shade: just as you seek natural cooling under the branches of a tree, sun protection keeps the sun out and your home, patio and workplace pleasantly cool. It offers natural air conditioning for your home which is healthy but also environmentally-friendly.
