The Soundblocker Plus is a 3mm acoustic underlayment that is odorless, non-toxic and good performance. With an IIC 73 and STC 72 the Soundblocker Plus can greatly reduce the noise provoked by foot traffic, conversation, music, dropping items on the floor, and other common sources of noise.
Because of the properties of its material, the Soundblocker Plus can also act as a moisture barrier, protecting your flooring against damages caused by vapor coming from the under-floor (recommanded for basemans). Covers 200 sq.ft.
