WELS2 fabric for flame retardant curtains, the best classification according to UNE-EN 13773


Fires inside houses or buildings spread very fast. A small flame is able to fill a whole big area with a dense black smoke or surround it in flames in less than a minute. It only needs to find enough combustion material in order to raise its size and heating power. Also, the heat generated by the flames themselves is even more dangerous than the flames themselves.


One of the key factors when contributing to the destructive power of a fire in the interior is the quantity of NON-fireproof material found in the area. In other words, the more furnitures, fiber textiles, household appliance accessories, in the end, flammable objects, the most dangerous and devastating the fire will be once unleashed. It’s for this reason that the need to own as much flame retardant elements as possible appears, also duly certified with official current regulations.
