Double Set Acoustic Floor Underpad Roll
Double Set is a wide-coverage recycled-rubber underpad — each roll lays 135 sq ft of continuous decoupling beneath floating plywood, engineered hardwood, or LVP finish floors. It breaks the direct impact-vibration path between the finished floor and the structural subfloor without adding excessive height.
- 135 sq ft per roll: Wide-coverage roll — fewer seams and faster install across large floor plates.
- Recycled rubber composite: Dense recycled-rubber underpad delivers acoustic mass and long-term resilience.
- Loose-lay, no fasteners: Floats between subfloor and finished floor — no penetrations through the decoupling layer.
- Floating-floor ready: Spec'd for plywood + finished-floor sandwiches used in the highest-tier floor assemblies.
