 Massive Bulk Kit – 20 Sheets, 98.34 sq ft Coverage
Each kit includes 20 large sheets (20" x 35.4" / 500mm x 900mm each) , offering a total of 98.34 square feet (9 m²) of acoustic foam. This generous volume lets you treat your entire vehicle – doors, roof, trunk, floor, and firewall – or even use it in home studios and workshops, all from a single purchase.

     Extra-Thick 15mm Wavy Foam for Superior Sound Absorption
At 0.59" (15mm) thick, this high-density closed-cell foam outperforms thinner 10mm or 12mm alternatives. The unique wavy (convoluted) surface increases surface area, effectively trapping and absorbing mid-to-high frequency noise, reducing cabin echo, road noise, and vibration for a quieter, more enjoyable ride.

      High-Density Closed-Cell Structure – Moisture & Oil Resistant
Unlike open-cell foams that absorb water and degrade, the closed-cell construction repels moisture, oil, and dust – preventing rust, corrosion, and mold. It maintains its acoustic and thermal properties over years of use, even in high-humidity or extreme temperature environments.

      Extreme Temperature Tolerance – From -40°F to +320°F
Engineered to withstand harsh automotive conditions, this foam resists temperatures from -40°F to +320°F (-40°C to 160°C) without melting, shrinking, or losing adhesion. Perfect for engine compartments, hot roofs, and cold winter climates alike.

      Peel-and-Stick Installation – DIY Friendly with Strong Adhesive
Each sheet features a pressure-sensitive adhesive backing covered by a craft paper release liner. Simply cut to shape with scissors or a utility knife, peel off the liner, and press firmly onto any clean, dry surface – no special tools or professional help needed. The strong bond stays secure even on vertical panels.
