The RSIM is designed for use with any wood, steel, or concrete floor structure where impact noise reduction is needed. The RSIM typically installs over the subfloor and directly under the finished flooring. The RSIM is available in 2mm, 3mm, 5mm, 6mm, 10mm, and 12mm thicknesses. The RSIM can be installed under LVT, rigid vinyl (SPC & WPC), ceramic tile, natural stone, solid and engineered wood, laminate, carpet, lightweight concrete/screed, and plywood rafts.
