GenieMat RST is a high-performance, resilient sound control underlayment engineered for direct installation beneath hard surface floor finishes. Manufactured from 94% recycled rubber, it provides superior impact sound insulation in multi-family housing, high-rises, and commercial buildings.
Developed from patented recycled rubber technology (US 6920723, US RE41945, CA 2398262), GenieMat RST reduces impact noise transmission while protecting ceramic tile, porcelain, stone, wood, and vinyl flooring from substrate cracks.
Designed for direct-adhered floor coverings, GenieMat RST offers long-term durability, crack isolation performance, and industry-leading acoustic results across concrete, wood, and steel construction assemblies.
