Enhance your driving comfort with the Car Soundproof and Thermal Insulation Deadening Mat. This highperformance accessory is meticulously engineered with highdensity rubberbased closedcell foam and an aluminum foil outer layer to provide superior noise reduction and heat protection. Specifically designed for vehicle interiors, it effectively blocks external temperature fluctuations and dampens structural vibrations, making your cabin quieter and more comfortable in all climates.Why Choose This ProductStandard vehicle panels often lack sufficient insulation, leading to excessive road noise and poor temperature regulation. This selfadhesive sound deadener solves that issue by utilizing a viscoelastic polymer layer that absorbs acoustic energy and blocks thermal transfer. The specialized closedcell architecture is specifically intended to be waterproof and moistureproof, preventing rust formation on internal surfaces. Unlike basic foam, this upgraded material is oil and petrol resistant, ensuring a durable, longlasting fit even in engine bays or chassis areas. It is a costeffective and essential investment for any car owner looking for a professionalgrade, easy “cutpeelapply” solution to improve ride quality and air conditioning efficiency.Perfect ForEngine Hood and Firewall: Blocking excessive engine heat and reducing noise directly from the source.Doors and Interior Walls: Enhancing audio speaker performance by eliminating panel rattles and vibrations.Trunk and Wheel Arches: Minimizing tire whine and road noise for a more refined cabin environment.Roof and Floor Insulation: Keeping the vehicle cooler in summer and warmer in winter by preventing temperature loss.Size GuideType SizeDimensions (Inches)Thickness400x250x10mm15.75 x 9.8410mm (0.39 in)Upgraded5mmVaries by Sheet5mm (0.20 in)Upgraded10mmLWhole Sheet Large10mm (0.39 in)
