Flexible, High-Silica Fabric for Welding Protection and Extreme Temperatures up to 2300F

Woven from yarn that is composed of more than 96% silica, Z-Sil™ Silica Fabrics provide superior protection from high temperatures, sparks, and slag. Z-Sil™ Silica Fabrics are treated with an inorganic high temperature coating that improves abrasion resistance and remains with the fabric even at high temperatures.

We offer Silica Fabrics in 2 weights: 18 ounces per square yard for applications where flexibility is important or 36 ounces per square yard for applications where superior insulation is necessary. Both styles can be laminated with Z-Flex Aluminized lamination for radiant heat protection.

Z-Sil™ Silica Fabric supports continuous operating temperatures up to 1800°F / 980°C and peak temperatures up to 2300°F / 1260°C.

Because of its superior temperature resistance, silica heat resistant fabric is ideal for protecting people and equipment during metal cutting, stainless steel welding, and heavy welding operations. 

Z-Sil Silica Fabric has been tested to the following standards:

  • Tested to the ANSI/FM 4950 Standard

Common Applications

  • Welding blankets
  • Welding curtains
  • Equipment protection
  • Insulation layers in pads and jackets
  • Welding pad
