Acoustic Underlay
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.
High-Performance Acoustic Underlayment for Floated Floors
Engineered for superior acoustic performance, this underlayment is designed to dramatically improve the Impact Insulation Class (IIC) and Sound Transmission Class (STC) ratings of a flooring assembly. Its primary function is to decouple the finished flooring from the structural subfloor. This separation creates a barrier that absorbs the energy from impact sounds, such as footfalls, and dampens airborne sound transmission between rooms.
The core of the underlayment is a dense, flexible, rubberized asphalt membrane. This material provides the necessary mass to effectively deaden sound vibrations. Its inherent elasticity also functions as an uncoupling or anti-fracture membrane. When applied over concrete or wood subfloors, it isolates the flooring above from lateral stresses, shifts, or cracks that may develop in the substrate, thereby protecting brittle flooring finishes like tile and natural stone from damage. The non-woven fabric on the surface ensures a strong bond with thin-set mortars or adhesives, while the peel-and-stick application ensures a quick and secure installation.
