Resilmat® W20R Sound Isolation Washer


The W20R is a sound isolation washer used in conjunction with the Resilmat – RMI recycled rubber underlayment to be used directly under most floor and ceiling sills. The W20R is used in these sills by drilling holes up to 3/4”in diameter, every 16” to 24” (Consult local code) whether it is wood or metal track. Insert a fastener through the hole in the center of the W20R Washer and then fasten the plate to the floor.  For more information on this assembly see our Resilmat – RMI page.
