Automotive aluminium foil sound insulation firewall heat and sound insulation mat polyester fibre rectangle 50cm by 200cm in 5mm 10mm or 15mm thickness silver colour
Automotive aluminium foil sound insulation mat for firewall heat and noise reduction in 50x200cm sizes

Engine bay heat and road noise can make driving uncomfortable, especially on longer journeys. This aluminium foil sound insulation mat is designed to be installed on the firewall or other vehicle panels, reducing the amount of sound and radiant heat that enters the cabin. Made from a polyester fibre core with an aluminium foil facing, it offers a practical solution for modifying cars, vans, and commercial vehicles. Available in three thicknesses, you can choose the level of insulation that suits your project.
Features and Construction

The mat is built from two functional layers: a reflective aluminium foil outer layer and a sound-absorbing polyester fibre core. This combination helps to dampen airborne noise while reflecting heat away from the cabin.
Material and Build
The aluminium foil facing provides a heat-reflective surface that helps to lower under-bonnet temperatures. The polyester fibre core is designed to absorb sound energy, reducing the transmission of engine and road noise through the vehicle structure.
Size and Practical Fit
Each mat measures 50cm by 200cm in a rectangle shape, giving a generous continuous sheet that can be cut to fit irregular panels. Thickness options of 5mm, 10mm, or 15mm allow you to match the insulation density to available space and desired performance.
Uses and Placement

This insulation mat is intended for automotive use, particularly on the firewall between the engine bay and the passenger compartment. It can also be applied to floor pans, transmission tunnels, or door panels.
Event or Professional Use
Garages and vehicle conversion specialists can use this mat to reduce cabin noise in custom builds, camper vans, or fleet vehicles. The aluminium foil layer also helps protect against heat damage to adjacent components.
Everyday Home Use
For DIY enthusiasts, this mat is straightforward to cut and fit using basic tools. It can be trimmed to shape with a knife or scissors, making it accessible for one-off projects on family cars or hobby vehicles.
Benefits and Buying Value

The combination of heat reflection and sound absorption in a single sheet simplifies installation and reduces material costs. The choice of thickness lets you balance insulation performance with budget.
Reuse and Low Maintenance
Once fitted and properly adhered, the mat requires no routine maintenance. The aluminium foil facing resists minor oil splashes and is easy to wipe clean if needed.
Why Choose This Product
This mat offers a practical, cost-effective way to improve cabin comfort by reducing both heat and noise transmission through the firewall. With three thickness options and a large 50x200cm size, it covers a significant area and can be adapted to many vehicle types.
