Our underlay is made from recycled PU and Latex Rubber Foam. The foam that is used in the manufacture would otherwise be in a landfill. Instead it is purchased by Sleepyhead and this means that the underlay is a very environmentally friendly product. The underlay can be continuously recycled. Furthermore, this underlay is a product that is designed to last beyond the life of the carpet. The underlay has been tested against and conforms to AS 4288:2003 and ISO 9073-3 1989. This underlay comes in rolls that are 15 m long and 1.830 metres wide. The rolls are packaged in plastic. The backing of the Underlay is a 10 x 8 mm reinforced polyurethane mesh. This is laminated to the foam underlay using a heat transferred plastic film with added slip to assist installation.
