This ‘accordion style’ underlayment was built for speedy installation. Its rigid structure lays flat and has a printed grid on top which makes it easier to lay out and trim to fit a room. SilverStep’s cross-linked (closed cell) foam provides superior protection from both moisture and sound (noise) sources. SilverStep’s 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. 3.2 mm cross-linked polyethylene foam Superior sound-dampening & moisture barrier Flat-folded, lays flat during installation, easy storage and use Positioning tape seals out moisture, speeds installation Double protection: Cross-linked with added film barrier Package unfolds to 28’ x 43” x 3.2 mm for a total of 100 sq ft Shipping Details Item: FU81422 UPC: 050462814226 Dimensions: 4⅜" X 10¼" X 43½" Weight: 2 lbs Pallet QTY: 14 Dimensions: 48 x 40 x 51½ Weight: 161 lbs
