Extended
Extend the fabric as far as needed to shade the glass roof and keep the room noticeably cooler on hot days.
Say goodbye to the greenhouse effect beneath a glass roof. This exterior awning stops the strongest sun before it heats the room, keeping the interior pleasantly cool and bright. A counter-tension mechanism keeps the fabric smooth across areas of up to 50 m².
The same structure works in every season: in summer the fabric shades the glass roof; when shade is no longer needed, it retracts neatly into the cassette without changing the façade’s appearance.
Extend the fabric as far as needed to shade the glass roof and keep the room noticeably cooler on hot days.
The arms and fabric fold away at the cassette, letting light—and in winter, solar warmth—pass freely through the roof.
A spring-tension system keeps the fabric taut and ensures smooth retraction without sagging.
One section covers up to 25 m². Two systems can be joined on a shared double guide to cover up to 50 m² in one line.
A 230 V/50 Hz motor integrated into the roller stops automatically at the end positions and if overloaded.
Choose a remote control, wall switch or radio motor. Sensor-based automation is recommended to retract the awning automatically in bad weather.
Acrylic fabrics absorb almost all ultraviolet radiation.
An additional support shaft at the centre of the front edge keeps the fabric taut on larger installations.
Type 820 follows the technical description and drawings in TESTRITE’s own 2009 catalogue. The product is based on the Sundream system by German manufacturer Angstrom Voss. The catalogue photos and some specifications, including colours and fabric counts, come from that manufacturer’s materials.
