Datanly 16" x 118" Thermal Sound Deadening Mat — 10mm Thick Reflective Insulation, Self-Adhesive for Cars Trucks SUVs

Datanly 16" x 118" 10mm thermal sound deadening mat is a heavy-duty, self-adhesive aluminum-foil insulation that cuts engine and road noise while reflecting heat in cars, trucks, SUVs and RVs.

This reflective insulation mat combines a thick closed-cell foam layer with an aluminum foil facing to deliver both acoustic damping and thermal barrier performance. At 10mm (394 mil) thickness and a coverage of approximately 12.91 square feet per sheet, the mat is sized to tackle common problem areas such as doors, floors, roofs, trunks and engine bays. It installs with a peel-and-stick backing and is designed for DIY application without specialty tools.

How does this mat reduce noise inside my vehicle?

The combination of thick foam and dense foil facing absorbs airborne sounds and reduces panel resonance that causes rattles. By damping vibration where panels meet the chassis, it lowers wind, road and engine noise, improving cabin quietness and perceived build quality.

• 10mm closed-cell foam dampens vibrational energy.
• Aluminum face reduces sound transmission and reflects noise waves.
• Covers large panel sections to stop common rattle points.

Will it actually block engine and sun heat?

The reflective aluminum surface deflects radiant heat while the foam core provides thermal resistance, so it limits heat transfer into the cabin and engine compartment. The manufacturer rates it to block a high percentage of radiant heat, which can help reduce A/C workload and protect nearby components from excess temperatures.

• Aluminum foil reflects radiant heat away from interior areas.
• Foam core slows conductive heat movement through panels.
• Can be applied to firewall, hood, engine bay, and roof to shield hot zones.

How easy is installation for a DIY project?

Installation is straightforward and intended for non-professionals: remove surface contaminants, measure and cut the sheet, peel the backing, and press into place. The heavy-duty adhesive sets quickly; hand or roller pressure ensures a secure bond and good contact with uneven surfaces.

• Simple five-step process: remove, clean, cut, stick, press.
• Works on doors, trunk lids, fender wells and flat panels.
• No heat gun required for basic application; trim with standard tools.

Which vehicle areas benefit most from this insulation?

This mat is versatile and suitable for multiple zones where noise and heat are problems, including the engine bay and interior panels. It also helps reduce vibration-related wear by stabilizing panels and components, extending the life of clips and fasteners.

• Firewall and engine bay to reflect exhaust/header heat.
• Doors, roof and floor panels to cut road and wind noise.
• Trunk, fender wells and cargo areas for vibration damping.

Who is this for: Drivers, DIY mechanics, car audio installers and small-fleet owners who want a robust, do-it-yourself solution to cut cabin noise and heat. It’s a practical choice for anyone restoring a vehicle’s comfort, upgrading sound systems, or protecting components from thermal stress. Because it installs without professional equipment and fits a variety of panels, it’s useful for personal cars, trucks, SUVs and recreational vehicles looking for an affordable, heavy-duty insulation upgrade.
