The underlay plays an important role in the comfort a carpet offers. It serves as a cushion under the carpet which also offers a layer of insulation from the bare sub floor and greatly enhances the comfort and user experience. The two most common types of underlay include rubber and foam. They come in a range of thickness and density. The higher the thickness and density, better the insulation against temperature and sound. A good underlay also increases the lifespan of the carpet as serves as a protective layer. At Mike’s Carpets we offer more than 6 grades of foam underlays and 3 grades of rubber underlays to suit your specific needs.
