Superpad Acoustic Floor Underpad Roll
Superpad is a 5/8" (16 mm) dense recycled-rubber underpad rolled to 4.5' × 24' — a single 108 sq ft roll lays a heavyweight decoupling layer beneath plywood, engineered hardwood, or LVP floating floors. Its high mass and thickness break the direct impact-vibration path between the finished floor and the structural subfloor.
- 108 sq ft per roll: 4.5' × 24' roll — one roll covers a typical bedroom or home-office with minimal seams.
- 5/8" high-density rubber: Dense recycled rubber delivers heavyweight mass loading in a single loose-lay layer.
- 25 lb roll weight: Two-person handle-able roll — no crane, no lift assist needed for residential installs.
- Loose-lay, no fasteners: Floats between subfloor and finished floor — no penetrations through the decoupling layer.
