The Silencer Megabond 1/2" Under Carpet Floor Shop Roll is designed for maximum acoustic performance, this 1/2-inch thick closed-cell foam effectively absorbs high-frequency airborne noise that traditional sound deadening materials can’t eliminate — such as engine noise through the firewall, road noise from the floor, and vibration through the trunk.

Perfect for use under carpet, on the firewall, and in the trunk, this thicker foam layer delivers superior noise absorption and thermal insulation, especially when used with HushMat Ultra as a base layer. The result is a solid, luxurious ride with less vibration, heat, and fatigue.

With a pressure-sensitive adhesive (PSA) backing, installation is fast and hassle-free — no glue, prep, or special tools required.

Key Features:

• 1/2" thick acoustic foam for maximum airborne noise absorption.
• Ideal for firewalls, vehicle floors (under carpet), and trunks.
• Targets high-frequency noise traditional damping doesn’t block.
• Excellent when combined with HushMat Ultra for dual-layer insulation.
  
• Reduces vibration, road noise, engine drone, and heat.
• Peel-and-stick PSA backing – quick and easy installation.
  
• Delivers a quieter, more refined ride in any vehicle.
