Description

The Siless Liner is a 157 mil thick closed-cell foam mat specifically engineered for automotive insulation and noise reduction. Constructed from closed-cell PE foam, this material offers a highly compressible and lightweight solution for reducing road noise and heat. With a thickness of 157 mil (0.157 inches or 4mm), the Siless Liner provides effective thermal insulation and sound dampening. It can operate in temperatures up to 215 degrees Fahrenheit, making it suitable for various vehicle applications, including firewalls and doors. The material is tear-resistant and formulated to resist oil and water. The foam sheets feature a self-adhesive backing with waterproof glue, allowing for a simple peel-and-stick application. While the product is flexible and easy to work with, a roller is not included in the package, though installation instructions are provided. The total coverage area provided by the 39 included sheets is 51 square feet, with each sheet measuring 15.15x12.44 inches.
