Abstract

‘Enhanced’ 23/32-inch-thick OSB subfloor panels show reduced thickness swell, compared with regular OSB. The use of these enhanced OSB products may reduce the need for sanding of subfloors prior to installation of flooring during house construction. However, even enhanced OSB panels can swell significantly when wetted, and are at risk of mold and rot while they remain wet. Thus OSB should be protected from wetting during construction whenever possible.
