Uproll Acoustic Insulation

Uproll Acoustic Insulation

Part of the Isolgomma under screed acoustic range, Uproll acoustic under screed membrane is one of the most reliable and tested acoustic underlays on the market and represents Isolgomma’s many years experience in the production of solutions for impact sound insulation. It is supplied in rolls and produced using SBR fibres and granules hot compacted using a latex adhesive. A 300 g/m² black bituminous anti-stretch backing is applied on one side. A waterproof version – Uproll PTB is also available.

Uproll can be used as a sound insulation underlayment under screeds and floating floors for both residential and commercial use and can also incorporate underfloor heating systems. It’s unique distribution of rubber granules on the floor ensures excellent elasticity and provides superior floor impact sound insulation performance.

Isolgomma Uproll has an impact sound reduction value of ∆Lw ≥ 24 dB. The inherent low dynamic stiffness of ≤ 11 MN/m³ is particularly suitable under heavy-duty screeds.

All Isolgomma products are manufactured using technology that ensures a low environmental impact.
