8mm Hush Under Screed Acoustic Membrane - 1250mm x 10m roll

8mm Hush Under Screed Acoustic Membrane is a resilient acoustic isolation layer for installation directly beneath a floating 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. Hush Under Screed Acoustic Membrane serves as a dynamic break, effectively decoupling the screed from the structural floor below. This decoupling prevents 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 properties also contribute to improved airborne sound attenuation, making it effective across the full frequency spectrum. It 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 an indispensable 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.

CHARACTERISTICS

• Resilient acoustic isolation layer.
• Made of fine granulate of recycled rubber bonded with a polyurethane (PUR) elastomer.
• Acts as a dynamic break, decoupling the screed from the structural floor.
• Significantly reduces the transmission of impact sound (e.g., from footfall).
• Enhances airborne sound insulation between separating floors.
• Prevents impact energy from transferring directly into the building's structure.
