Model IsoLayment floor underlayment delivers noise
reduction between occupied spaces where hard floor
surfaces amplify impact noise. Direct tile, bond hardwood
or float engineered wood floors directly on Model
IsoLayment for a low profile and economical installation.
Manufactured from 98% post-consumer and post-industrial
recycled rubber, Model IsoLayment is the environmentally
friendly choice for commercial and multifamily projects.
