what is the purpose of red rosin paper
Red rosin paper In building construction red rosin paper is used to reduce air and moisture flow through a wall or floor, create a "slip sheet" so different materials can slip by each other as they expand and contract,[2] keep dust from working down through a floor, minimize squeaking,[3] and sometimes as part of built-up roofs. Rosin paper is also temporarily used to protect a work site during construction. Rosin paper may have a polyurethane coating to improve moisture resistance and tearing. It is not acid free particularly containing abietic acid and comes in many size rolls up to 96 inches (2.4Â m) wide.
