It is a peel and stick membrane ideal for reducing sound transmission and as an anti-fracture membrane. It is a rubberised asphalt membrane, which is laminated to a non-woven polyester fabric on the face and a siliconised removable release sheet on the adhesive side.

Our impact sound acoustic underlay’s are for every floor covering are high-quality products. They provide high impact sound insulation values, are very durable and low in emissions. Acoustic Underlay is a permanently elastic material and can be supplied in rolls, sheets or molded parts. Acoustic Underlay is suitable for all applications which require attenuation of impact s ound and vibration, durability and resistance to mechanical loads. Acoustic Underlay can be used for a wide variety of sports surfaces, floor covering, impact protection, sheets and tiles for building protection and for impact sound protection, materials for vibration technology and anti-slip mats for securing loads. Acoustic Underlay can be used for a large variety of applications; it is long-lasting, resilient and can be recycled. Our sound underlay products have an excellent ratio between impact sound improvement and structural height with negligible creep behavior, even under high static or dynamic continuous loads.

These layers are installed before the floor covering is added, whether it’s carpet, tiles, floorboards or a floating floor. The underlay is rolled out and glued to the subfloor (usually either a wooden frame or concrete slab) all the way to the edge.
