## Overview

Siless Liner 157 is a 4mm thick, closed-cell polyethylene foam mat designed for automotive sound deadening and heat insulation. It features a self-adhesive backing for easy installation, blocks 98% of radiant heat, and is fully waterproof and oil-resistant. Covering 9 sqft per roll, it offers durable, lightweight, and cost-effective thermal and vibration protection ideal for doors, floors, roofs, and engine compartments.

## Description

Siless Liner is a high density, closed cell foam that serves as an efficient heat and vibration absorber. Closed-cell foam is an effective material for reducing noise reverberations, and the Siless Liner is moisture-resistant, fire-retardant, and dust-free. Our heat-blocking foam rolls are pliable and easy to work with, and they install in minutes. The high-density closed-cell foam is perfect for firewall, doors, roof, trunk and floor. Siless Liner is the most effective automotive thermal insulator available online, and perfect to use on top of Siless Sound Deadening Mat. It is a soft, self-adhesive closed cell foam with many thousands of cells packed extremely close together, which gives the material near zero air infiltration. This is the key to its ability to reduce heat, as well as resist oil and water. Since it will not hold water, it will not promote rust like most under carpet padding and thermal insulators. Siless Liner is also durable enough to be crush and tear resistant. Because of its durability and ability to resist oil and water, Siless Liner is long lasting. Siless Liner has the highest heat blocking properties available in a single layer synthetic foam. Combined with Siless Sound Deadening Mat, its nearly doubles the total thermal resistance ability. It provides excellent insulation for the roof, firewall, floor, quarter panels, doors, and even under the hood.

Review: Easy to work with. The adhesive is sticky, duh. But what I mean is it's difficult to cut with scissors and sticks to fingers. It comes off by rubbing them on a cloth. Seems to stay adhered to walls and metals. I found it pretty satisfactory.
Review: I used this on the roof of my Chinese excavator. That thing was humming along quite well at many frequencies and needed to be attenuated. I bought this product for this purpose but quickly found out that it was not dense enough. While it did attenuate the noise by about 50%, the material is just not dense enough to get more out of it. I will say though that the glue they used is fantastic. If/when I remove it to install something different, it’ll be a chore to take it off.
