Customers say
Customers find the sound deadening material works well as an under-layer, particularly in engine bays of RVs, and effectively reduces road noise. The material adheres well to cleaned metal surfaces, is easy to apply to metal bodies, and cuts easily to shape. While customers consider it good value for money and appreciate its heat insulation properties, with one noting it helps maintain vehicle temperature, opinions about durability are mixed, with several customers reporting that it rips during installation.
