Product Description
Pliteq GenieMat RST is a high-performance recycled rubber acoustic underlay designed for impact and airborne sound reduction in residential and commercial floor build-ups. Available in thicknesses from 2 mm to 15 mm, it sits beneath screeds or floating floor systems to achieve significant improvements in weighted impact sound insulation, helping projects comply with Part E of the Building Regulations.
Key Benefits
Application
Lay GenieMat RST directly onto a clean, level substrate. Butt joints tightly together — no overlapping. Use with a polythene slip membrane on top before applying liquid or traditional screeds. Minimum screed thickness varies by mat thickness and screed type. Consult the Pliteq acoustic performance data for specification guidance.
Coverage
Roll dimensions vary by thickness. Standard rolls provide between 5 m² and 30 m² per roll depending on variant. Calculate the total floor area and select the appropriate thickness to achieve the required acoustic performance. Allow approximately 5% for cutting waste.
