Texfire’s flame retardant curtains for welding can be tailored up to measure according to our client’s needs. The maximum sizes for each curtain are 7,5x10 meters.

These curtains are tailored with WELS2 fabric. It is a flame retardant fabric made of fibreglass which brings mechanical resistance and flexibility, with a special silicone coating for high temperatures on both sides that repel sparks and projections coming from welding, curing and grinding operations. These welding curtains resist continuous temperatures of 300ºC and peak temperatures of 900ºC. Sews are also made with Nomex® flame retardant thread.

Texfire’s custom-made welding curtains have a reinforcement fold in all the perimeter that avoids tearing and incorporate grommets every 25 cm in the upper edge to ensure a stable holding. These curtains are completely opaque and waterproof before liquids and fumes, they can be used on both sides. Suitable to all kinds of welding (TIG, MIG, Electrode…) and cutting operations (radial, oxyfuel or plasma cutting). They are suitable to separate, define and ensure working areas, these curtains are flexible, light, and easy to clean with a wet cloth. They can be used in internal installations and outdoors.

WELS2 flame retardant fabric is certified in 2020 with regulation UNE 23727 -  Reaction to fire of building materials - with an M1 classification. And according to regulation UNE 13773 - Behaviour in front of the fire in curtains and drapery -, with a Class 1 classification. It also meets regulation EN ISO 9150 - Behaviour of materials before the impact of small melted metal splashes, with a Class 1 classification
