Semi-vana 21x1000x25000mm

Two-layer efficient sound insulation for narrow spaces that will also block low frequencies. The distancing and insulation layers make Semi-vana particularly suitable for the sound insulation of drainage pipes, ventilation ducts, walls and other structures such as the car chest plate.
The product meets the requirements of ISO 3795 and FMVSS 302, which means that it is self-extinguishing. The product can therefore be used as sound insulation in vehicles.
