Underlay or underlayment generally refers to a thin layer of cushioning made of materials such as fibre cement, sponge rubber, foam, felt, or crumb rubber; this material is laid beneath tiles or carpet to provide comfort underfoot and to reduce wear. It also provides insulation against sound, moisture, and heat. In general, it is a layer which is underneath another layer, so underlay is thus also used to describe many different surface-covering products such as Tiles, Vinyl and Cork.
