Delamination
What you need to know
Delamination occurs when the secondary backing separates from the carpet primary backing. This can occur in small areas, along the carpet edges and seams, or in large areas of the backing. Delamination can be manufacturing, installation, site, maintenance, or use and abuse related. The only standard for lamination strength is found in FHA/HUD UM44d, which sets minimum values for carpet that might be used in HUD or FHA housing. The minimum strength of 2.5 lbs. /inch of width is measured by a certified testing laboratory. Lamination strength minimums are not stated for carpet sold to other entities, however, the 2.5 lbs./inch is usually considered the acceptable minimum by the industry and has served well for 40 years.
