SUNLESS is a fabric created from state-of-the-art technical materials at the service of comfort and safety. This is without a doubt a product with excellent mechanical properties, as well as being flame retardant M-2, rated in accordance with standard UNE 23727-90. It has also obtained the B-1 rating according to the German standard DIN 4102.
SUNLESS is made of high-tenacity polyester thread that provides a lower rigidity against bending. This feature allows for the creation of an ideal product for outdoor use as it can better withstand any bending that fabric which is exposed to the elements is likely to undergo (wind, pressure, etc.). Moreover, its mesh-like structure prevents hot air from concentrating between the fabric and the glass, thus saving a lot of energy.
As with SUNLESS GLASS, its PVC coating prevents water from penetrating into the thread, making it resistant to rot, chemicals and weathering.
