VIBROFILTR PRO-4mm is the best sound insulator and vibration damper used in cars. MLC (mechanical loss coefficient) is 0.60 c.u., one of the highest in this class.

With a thickness of 4 mm, almost all harmful frequencies are suppressed, which is facilitated by the reinforced insulation layer. Synthetic sealant reinforced with polymer additives ensures fixation for the entire period of operation. The material is eco-friendly; it is regularly tested for protective properties. Like other materials manufactured using the technologies of NGO National Technologies, it has waterproofing properties.

Main characteristics:
