Tecsound FT55 AL (Acoustic Pipe Wrap) is a visco-elastic membrane, and this means it is both a viscous material, part way between a solid and a liquid, and has elastic properties, meaning that it returns to its original form when stresses within its limits are applied, like pulling an elastic band, if you pull it too hard it will break. For soundproofing, these are both effective in the damping of vibration, and because of its high mass, will reduce airborne noise too. Contact us today to find out more.
