Fiberglass flame retardant needling NT FIBERGLASS 3300 needled with fiberglass offers a resistance inherent to the flame. It is effective to block heat and to perform as a heat and acoustic insulator. Thanks to its thickness from 25mmm to 35mm, it offers a very significant blockade and conservation of temperature, for that reason this kind of mat is one of the most used in the tailoring of detachable heating pads, and can be found in multiple industries and sectors such as food industry, petrochemicals, shipbuilding sector...

Its balance in insulating features, flame retardant material and competitive cost, turns it into a suitable material to perform as an internal layer or stuffing of any kind of industrial crafts for high temperatures.

NT FIBERGLASS 3300fabric, does withstand temperatures up to 500ºC in continuous work arriving to withstand temperatures up to 0,176 W/m2 ºK in peak workloads.

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


Composition: >98% E-Glass
Weight: 3300g/m² ±5%
Width: 100 cm ±2%
