Fire Rated Cable Matting | Class 0 Nitrile/PVC Sponge Sheeting

Metroseal

Fire Rated Matting

Metroseal ER22 Class 0 Nitrile/PVC Sponge Sheeting is a range of insulating matting specified for fire rated cable matting and cable protection applications – the fire rated matting is available in rolls or sheets in an excellent thermal insulator (sealing) material. The PVC cable sponge sheeting is available with a self adhesive backing for ease of application.

Flexible closed cell elastomeric thermal insulation material for condensation control in air-conditioning, refrigeration and chilled water installations. Class 0 Nitrile/PVC Sponge Sheeting is also suitable for reducing thermal losses in heating and plumbing systems.

The combination of technical properties, a low thermal conducting and a high resistance to water vapor transmission and competitive price makes it a cost effective energy saving solution.
