Novostrat has added to its Sonic and Comfort ranges of underlays with the introduction of Sonic Gold Excel.

Developed for laminate, solid wood and engineered timber floors in domestic and commercial applications, the underlay comprises three layers. The floor-side lamination is a 100 micron low-density polyethylene black vapour control barrier and the top lamination is a gold foil facing that extends to form a 200mm overlap, on both sides. This is to avoid acoustic bridging and to facilitate continuity in installation. Sandwiched between these layers is Novostrat’s high-density polyethylene foam which provides the product’s sound absorption and impact-resistance qualities. It also helps even out imperfections in the deck on to which the floor is laid.
