Abstract

See full text

A floor covering, such as a carpet or carpet tile, which comprises a primary backing sheet having a fibrous face wear surface and back surface and first and second backing layers and with a low density, resilient, non-elastomeric, closed cell polymeric foam layer, such as a thermoset, cross-linked polyethylene foam layer, positioned between and bonded to the first and second backing layers, optionally with a secondary backing layer bonded to the secondary bitumen backing layer. A method of producing a floor covering, such as a carpet tile, which comprises providing a primary backing sheet having a fibrous face wear surface and a back surface and bonding a first bitumen backing layer onto the primary backing sheet, bonding a low density, thermoset, polymeric foam layer to the first bitumen backing layer through a glass tissue to protect the polymeric foam layer and stabilize the composite, and bonding a second bitumen backing layer onto the polymeric foam layer. The second bitumen layer being beyond to a non-woven base wets through a glass tissue to protect the subfloor and stabilize the composite.
