Roll Under Screed Acoustic Insulation

Roll Under Screed Acoustic Insulation

Isolgomma Roll under screed acoustic insulation 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. Roll is also suitable for use with underfloor heating systems. Impact sound reduction value (ΔLw) is 22dB.

The unique distribution of rubber granules on the floor ensures excellent elasticity, making Roll perfectly suitable for impact noise reduction. The 5mm thickness also makes it suitable for renovation projects where the system has to adapt to onsite needs without compromising the overall performance. Roll is also available in a 9mm version – Uproll.

Another important feature of Isolgomma Roll is that it is free of  VOCs (Volatile Organic Compounds). VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. By using VOC free Isolgomma products in your building project you are ensuring that resources are used responsibly and efficiently while not compromising the user’s comfort and health. In the long run, they help save money, protect the environment, promote better health, and most importantly, lead to a more sustainable future.
