Abstract
The present invention relates to a method of making a laminated product, such as an insulator pad comprised of foam and stiffening layers held together with adhesive. A thin protective barrier foam sheet is placed between the surface of a compression roller and the sheets to be laminated together by passing them between compression rollers. The thin protective barrier foam sheet may or may not form the outer layer of the laminated product and prevents adhesive and foam material from contaminating the surface of the roller.
