Made in Mainland China.

Key Features

• Effective Sound Absorption: High-density rubber foam absorbs sound waves and dampens vibration, while the reflective aluminum surface bounces back additional noise. The result is a significantly quieter cabin, even at highway speeds.
• Dual-Layer Thermal Barrier: The composite of aluminum foil and dense foam cotton reflects heat away from your vehicle's interior, helping keep it cooler in summer and warmer in winter — all without extra weight or bulk.
• Premium, Long-Lasting Materials: Constructed from durable rubber foam with a reinforced aluminum foil outer layer. The foam provides excellent compression resistance, so the mat retains its shape and performance over years of use.
• Self-Adhesive, Tool-Free Installation: Simply clean your surface, peel off the backing paper, press the mat firmly into place, and smooth it down. No additional tools, no mess — installation takes minutes.
• Versatile Fit: Compatible with most vehicle makes and models. Apply to doors, floors, trunk/boot, hood/bonnet, ceiling, firewall, fender, chassis, and more for comprehensive coverage wherever you need it.

Frequently Asked Questions

Q: What surfaces can I apply the car sound deadener insulation mat to?

A: This insulation mat can be applied to virtually any flat or slightly curved surface inside or outside your vehicle's cabin, including doors, floors, the trunk/boot area, hood/bonnet, roof lining, firewall, chassis, and fenders. Its flexible rubber foam construction conforms well to most surfaces.

Q: What is the difference between the 5mm and 10mm thickness options?

A: The 5mm mat is ideal for areas where space is limited, such as door panels and under carpet. The 10mm mat provides enhanced acoustic dampening and thermal insulation for larger, more open areas like the hood, trunk, and floor — where the extra thickness can make the most noticeable difference to cabin comfort.

Q: Is this car insulation mat easy to cut and shape?

A: Yes. The rubber foam material can be easily trimmed with a utility knife or sharp scissors to fit any shape or contour. This makes it straightforward to cut around wheel arches, cable runs, or irregular panel shapes without any specialist tools.

Q: How many sheets do I need for a full car interior?

A: The number of sheets needed depends on your vehicle size and the areas you wish to cover. For a full floor and door treatment on a standard car, a pack of 10–20 sheets is typically sufficient. Larger vehicles like vans or SUVs may benefit from the 20-sheet pack for comprehensive coverage.
