Thermotec Premium Carpet Underlay is part of Thermotec's high-performance NuWave Noise Barrier range of products. Thermotec underlay reduces noise in both directions - noise travelling down through the floor and up through the ceiling. Thermotec underlay is a high-performing acoustic underlay that will ensure your application has the best soundproofing. Due to its innovative design and performance, Thermotec underlay is effective for reducing airborne and impact noise, such as when your upstairs neighbours walk or move furniture. Thermotec underlay consists of a flexible, high-density limp mass polymer that absorbs the energy of sound waves across the hearing frequency spectrum, with a low-density, direct extruded closed-cell polyethylene adhered to the underside of the product. Thermotec underlay utilises energy-absorbing foam and a blocking barrier to reduce noise transmission through floors.
