In an era of recalls, Len-Tex ensures the safety of its wallcoverings by using only first-generation raw materials. The use of certified first-generation raw materials gives Len-Tex customers confidence that their wallcovering will meet stringent specifications going beyond industry standards. Recycled vinyl products may contain lead, mercury, cadmium and other heavy metals – materials present in older vinyl products. Only by using first-generation raw materials can Len-Tex or any manufacturer ensure that toxic materials are not found in new wallcoverings. Len-Tex takes an extra step, requiring Certificates of Analysis from all suppliers to ensure that all raw materials conform to written specifications.
