Aluminized flame retardant fabric WELS1 ALP
, has a coating of black silicone on one side, and a aluminizing process with aluminium particles, resistant to high temperatures, on the other side. It is mainly designed to be used as a thermal barrier, oven doors or vertical curtains, because it allows the insulation of radiant heat sources, the same time it offers good protection to small splashes of melted metal.

WELS1 ALP fabric is a flexible and light fabric, it can withstand temperatures up to 350ºC in continuous work arriving to 550ºC in peak workloads. It admits a horizontal use in certain working situations.

  • Insulation against radiant heat
  • Flame retardant in both sides

  • Resistant to small splashes of metal in fusion
  • Water resistant
  • VERTICAL use in both sides.
