Fibreglass wool for silencers 250g bag Thermo filling for silencer soundproofing

Fibreglass wool for silencers in a 250g bag is a thermo-insulating filler for soundproofing silencers.

It is characterised by its high thermal resistance, has improved acoustic properties and high mechanical strength.

ECR matting is an insulating material consisting of textured continuous glass fibres. It features a number of advantages. Due to its high thermal resistance, excellent acoustic properties and mechanical strength, it is used as a filler material for car silencers, motorbike silencers, quads (atv tuning and motorsport), power generators, technical equipment, industrial exhaust systems, gas and steam exhausts, industrial noise absorbers, acoustic enclosures and screens, curtains, welding, bakery equipment, heat insulating covers, protective clothing, etc. And in many other industries where there is a need to cope with the harsh working conditions of insulation subjected to high pressure, temperature and mechanical vibration.
