## Overview

Siless Liner Foam Dampening Material is a 157 mil thick, closed-cell polyethylene foam designed for passenger cars. It offers superior thermal insulation by blocking 98% of radiant heat and effectively deadens vibrations and noise. Waterproof, oil-resistant, and durable, it installs easily with a self-adhesive backing and covers 30 sqft per roll. Ideal for firewall, doors, floors, and trunks, it enhances comfort and protects your vehicle from heat and moisture damage—all at a fraction of the cost of similar products.

## 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.

## Questions & Answers

**Q: Is this better than the aluminum 157mil product?**
A: Use peel and seal which is the butal aluminum kind,  and its way cheaper! Then use this padded deadener on top of that !!

**Q: What is the width of the roll?**
A: Thank you for your question.

The width of Siless Liner is 16 inches.

**Q: Hi i am trying to Insulate my cargo van mercedes sprinter 2022 170 wb extended how many rolls do i need and will this work to control the temperature**
A: You should be able to determine how many rolls you'd need by measuring the interior area you want to cover then comparing it to the roll size (which I believe is in the product description) As for temperature control I don't think this product is thick enough to have an impact on that.

**Q: what kit would be best to do whole inside of my 1964 VW bug?**
A: Hi there! I suggest  buy  36.5 sqft 4 mil enough for VW ,   Just working on 71 super beetle and cover door interiors  ,cargo area( rearfirewall) and roof ! Have fun!
