Foam Panel Category — 2-Pack Closed-Cell Self-Adhesive Foam; 16 × 12 × 1.8-inch Extra-Thick “Egg-Crate” Soundproofing Foam; Provides Both Soundproofing and Thermal Insulation (Black)

Unlike traditional open-cell acoustic foam, this 2-pack foam panel set utilizes closed-cell polyethylene foam (XPE material), offering excellent water resistance, moisture resistance, thermal insulation, and effective soundproofing capabilities. Each panel measures 16×12×1.8 inches, features an embossed egg-crate surface texture, and comes with a self-adhesive backing. The closed-cell structure prevents air penetration, making it more suitable for blocking sound transmission (soundproofing) rather than merely absorbing echoes. With a thickness of 1.8 inches and a density of approximately 28 kg/m³, it effectively reduces sound transmission in the mid-to-high frequency range. Each package contains 2 panels, providing a total coverage area of ​​approximately 2.67 square feet. Applicable Scenarios: Automotive hood soundproofing, vibration damping and noise reduction for household appliances (such as dishwashers and washing machines), HVAC duct insulation, and small spaces requiring simultaneous noise and temperature control (e.g., studio ventilation vents). The black material is oil-resistant and can be easily cut into any desired shape using standard scissors. The self-adhesive backing is temperature-resistant (ranging from -20°C to 80°C), ensuring a durable and secure bond after installation.
