The ROBERTS Super Felt premium underlayment is a 3 mm thick insulating underlayment made to reduce noise and help cushion flooring. By absorbing noise instead of deflecting it, Super Felt reduces sound transmission. This felt underlayment is made from recycled fibers and compressed using a high heat manufacturing process. The film overlay protects engineered and laminate flooring from any moisture from the subfloor and includes a 1-3/4 in. adhesive strip and 3 in. overlap for linking multiple rolls.
For use with engineered wood and laminate flooring
