4.5mm Hush Over Screed Acoustic Membrane - 1m x 20m roll

4.5mm Hush Over Screed Acoustic Membrane is a resilient acoustic isolation layer for installation directly beneath a floating screed, such as a sand/cement or proprietary levelling screed. This membrane is a critical component in robust acoustic floor constructions, designed to significantly reduce the transmission of impact sound and enhance airborne sound insulation between separating floors. Composed of a fine granulate of recycled rubber with a cork and PU elastomer bonding agent, this membrane acts as a dynamic break, effectively decoupling the screed from the structural floor below. This membrane provides excellent resilient properties, preventing impact energy (from footfall, furniture movement, etc.) from transferring directly into the building's structure and radiating as noise into the room below. Its mass and resilient characteristics also contribute to improved airborne sound attenuation, making it highly effective across the full frequency spectrum. The Hush Over Screed Acoustic Membrane is highly durable, resistant to compression, and designed to maintain its acoustic performance over the long term, even under the significant weight of a screed. Its inherent flexibility allows it to conform to minor irregularities, ensuring a continuous and effective isolation layer. This membrane is the solution for achieving compliance with Building Regulations Part E (Resistance to the Passage of Sound) and other acoustic performance standards in various developments, including multi-residential buildings, hotels, educational facilities, and commercial spaces. By effectively isolating the screed, the Hush Over Screed Acoustic Membrane plays a vital role in creating quieter, more comfortable living and working environments.
