Soundproofing Membrane ISOLfon BARRIER 3.5R, thickness 1.80mm and roll dimensions 1x5m.

The ISOLfon BARRIER 3.5 is a soundproofing viscoelastic membrane, with a weight of 3.5 kg/m². It provides an increase in soundproofing capability in light and dry construction. It is an elastic material that has a high surface weight, small thickness, high mechanical strength, and flexibility.

Its composition includes an unreinforced polymer mixture, with the addition of inert materials. It is environmentally friendly and does not contain bituminous mixtures and lead.

It can be applied over a wide range of temperatures, maintaining its soundproofing properties. Placing it between rigid sheets, such as drywall, reduces the phenomenon of dip at the resonance frequency, enhancing the soundproofing capability in this frequency range.

Its large surface mass reflects annoying noises and increases the overall soundproofing capability in structural applications such as walls, ceilings, and floors.
