Flame retardant nonwoven fabric NT FIBERGLASS 1500 is a E-Glass fiberglass needling that offers an inherent resistance to flames. It is very effective to block heat thanks to a combination of thermal conductivity with an optimized fiber density. It is mainly used as a filling or internal layer in heating pads or textile lagged, thanks to its flexibility, great durability and low cost. Its structural fragility requires that it is always used with other fabric layers with higher stability

NT FIBERGLASS 1500 mat can withstand temperatures up to 500ºC in continuous work arriving to withstand temperatures up to 0,176 W/M2 ºK in peak workloads.

  • Fireproof, does not burn nor melt
  • Flexible
  • It can detach fibers
  • Free of asbestos and toxic gases
  • Density of 128kg/m3


Composition: >98% E-Glass
Weight: 1500g/m² ±5%
Width: 100 cm ±2%
Thickness: 10 - 12 mm
