6mm x 500x2000mm (20x79 inches) Thermal and Sound Insulation Mat for Truck/Auto Firewall

Features: Strong sound insulation and absorption, thermal insulation, damping, and antiseptic properties. In winter, the engine temperature is very high, but the outside temperature is very low while driving, which can easily damage car parts. Scratch-resistant. The surface fabric is made of fiberglass. Heat-resistant, it blocks the transmission of sunlight, engine heat, and exhaust heat to the cabin, reducing air conditioning energy consumption and saving fuel. Slows down car paint aging: Due to the heat, the front exterior cover is directly exposed to the sun and high temperatures inside and outside the engine, which accelerates paint aging. You can also use it on the car's roof, hood, firewall, chassis, trunk, trunk lid, and so on. Do not cover chassis wiring or air vents. Description: Size: 6mm 500x2000mm 20"x79" This amazing product will keep your vehicle's interior cool and quiet. It's easy to install and prevents unwanted heat and noise. It works so well that if you put it in your doors, it gives them a solid, modern sound when they close. It can be used on floors, firewalls, door panels, the trunk, the roof, and any interior areas that need insulation. Material: Aluminum fiber and cotton for mufflers. Powder-free and excellent vibration resistance. Excellent sound absorption properties. Does not contribute to metal corrosion. Very clean, does not absorb odors, odorless. Easy to install, suitable for all types of vehicles. Self-adhesive backing & waterproof and dustproof. Note: Do not apply directly to a heat source, especially hot exhaust pipes, mufflers, or turbo pipes. Compression will result in some volume reduction, but this does not affect its use. If this is a concern, you can purchase a thicker sheet to suit your needs. Installation instructions: 1. Clean the surface where you wish to apply the adhesive. 2. Ensure the insulation material and the sheet metal fit together firmly for optimal adhesion and damping performance. 3. Do not cover chassis wiring or ventilation holes during installation. 4. Proper use of adhesive tape will enhance the bond. 5. The soundproofing/damping aluminum sheet is in paste form. You can heat it with a hairdryer to make it pliable, then flatten it by hand. If the room temperature is below 5 degrees Celsius, first heat it with a heat lamp until it is pliable. Then, remove the backing paper and apply the adhesive. 6. For successful installation, it's best to avoid repeatedly tearing the adhesive; this will preserve its effectiveness. 7. Additional insulation can be applied in a hidden location. 8. A simple door installation won't have any effect on soundproofing; a complete installation is required. 9. Perfect for doors, roofs, floors, hoods, firewalls, chassis, trunks, trunk lids, and so on.
