Made from high-density closed-cell foam, the mat blocks heat, resists moisture and helps damp vibrations, while the included rubber rollers ensure strong, even adhesion during installation. The kit contains one 20 x 236 inch roll and two rollers sized for both flat areas and tighter curves.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this mat reduce in-cabin noise?\u003c\/h3\u003e\n\u003cp\u003eThe closed-cell structure traps and dissipates sound waves and engine vibrations before they reach the passenger compartment. By adding mass and damping to panels, it lowers resonance and cuts high- and mid-frequency noise that causes cabin chatter.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThick 196 mil (≈5 mm) foam increases panel mass and reduces vibration.\u003c\/li\u003e\n  \u003cli\u003eHigh-density sponge pores break up sound transmission through metal panels.\u003c\/li\u003e\n  \u003cli\u003eSelf-adhesive backing creates a tight bond that prevents air gaps and flapping.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it help control engine or solar heat?\u003c\/h3\u003e\n\u003cp\u003eThe material reflects and slows heat transfer thanks to its closed-cell makeup and thermal resistance.
