5mm XPE Foam Car Sound Deadener Mat – Hood & Door Insulation

Upgrade your vehicle's interior comfort with this 5mm XPE Closed-Cell Polyethylene Foam Sound Deadener Mat. Engineered with a self-adhesive backing, this high-performance insulation pad is a simple, effective way to reduce cabin noise, regulate temperature, and protect your car's interior — no professional installation required.

Key Features

• Versatile Placement: Designed for use on the hood (bonnet), car doors, ceiling, cockpit floor, tailgate, firewall, mudguards, and wheel wells — virtually anywhere you need acoustic or thermal insulation.
• Noise Reduction: The dense XPE foam structure absorbs engine rumble, tyre hum, road noise, and wind noise, delivering a noticeably quieter, more refined cabin experience.
• Thermal Insulation: Acts as a thermal barrier, helping keep your vehicle cooler in summer and warmer in winter — reducing the load on your air conditioning and improving fuel efficiency.
• Self-Adhesive & Easy to Install: Simply peel, cut to size, and press into place. Bonds firmly at temperatures above 0°C without any additional heating tools. Higher ambient temperatures create an even stronger bond.
• Waterproof & Flame Retardant: Made from premium rubber XPE foam with a fiberglass surface cloth. Moisture-proof, scratch-resistant, heatproof, and flame retardant for lasting durability.
• Protects Vehicle Components: Helps dissipate engine heat from the hood, slowing the aging of car paint and extending the lifespan of pipes, wiring, and under-hood components.
• 5mm Thickness: Slim yet highly effective — fits most door cavities and hood spaces without interfering with panels or mechanisms.

Installation Tips

1. Clean the surface thoroughly and allow it to dry completely before applying.
2. Cut the mat to your desired shape using scissors or a utility knife.
3. Peel off the adhesive backing and press firmly onto the surface.
4. For best results, apply at ambient temperatures above 0°C. Warmer conditions produce a stronger, more permanent bond.
5. Tip from the pros: For door insulation, apply a vibration-damping plate first, then layer this foam mat on top for a dual-layer acoustic system.

Frequently Asked Questions

Q: What vehicles is this XPE foam sound deadener mat compatible with?

A: This sound deadener mat is a universal-fit product, compatible with the vast majority of cars, trucks, SUVs, and vans. It can be cut to any shape or size, making it suitable for virtually any vehicle make or model. It works on doors, hoods, ceilings, floors, and more.

Q: How many pieces do I need to soundproof my car doors?

A: The number of pieces needed depends on the size of your vehicle's doors and how much coverage you want. For a standard 4-door sedan, 2–4 pieces typically provide good coverage across all door panels. For a larger SUV or truck, you may want additional packs for full coverage.

Q: Is this foam mat safe for engine bay / hood use?

A: Yes. The XPE foam features a flame-retardant rating and a heatproof fiberglass surface cloth, making it suitable for hood/bonnet applications where exposure to engine heat is a concern. Always ensure surfaces are clean and cool before application.

Q: Can this mat be removed once applied?

A: The adhesive is designed to create a very strong, permanent bond — especially when applied at higher temperatures. While it can be removed with effort (using a heat gun or adhesive remover), it is best treated as a semi-permanent installation. Plan your placement carefully before applying.
