CalFlor SilverStep 100 sq. ft. 43 in. x 28 ft. x .132 in. Premium Cross-Linked Polyethylene Foam Underlayment & Moisture Barrier

Cal-Flor's SilverStep underlayment is folded in an accordion style to speed up the installation process by lying flat and not curling or re-rolling. This underlayment has a printed grid on top, which makes laying and trimming to fit a room easier. SilverStep's cross-linked (closed cell) foam provides superior protection from both moisture and sound (noise) sources (IIC 72; STC 66). The extra thick pad provides good thermal insulation properties and makes it especially suited for subfloors with a rougher than normal finish. This underlayment can be used on radiant heat floors.
