## Overview

Siless LinerPRO 2in1 is a 5mm thick, dual-layer closed-cell polyethylene foam combined with b mastic, designed to deliver superior automotive sound deadening and heat insulation. Covering 36 sqft per pack, it blocks 98% of radiant heat, is fully waterproof and oil-resistant, and installs easily with a strong self-adhesive backing. Durable and lightweight, it enhances vehicle comfort by reducing noise, vibrations, and temperature extremes, all at a fraction of the cost of comparable products.

## Description

Siless LinerPRO is a high density, closed cell foam that serves as an efficient heat and sound absorber. Closed-cell foam is an effective material for reducing noise reverberations, and the Siless LinerPRO 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 LinerPRO 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 LinerPRO is also durable enough to be crush and tear resistant. Because of its durability and ability to resist oil and water, Siless LinerPRO is long lasting. Siless LinerPRO 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: Can you paint the outside of this product?  Looking for something to line the inside of the cabinets in my Motorhome ti help with heat**
A: I would not paint it. It is a sponge foam. The lighter 80mil would be better to paint with the aluminum backing. Be sure to use high heat paint

**Q: What vwlse should bebused with b this**
A: I used fiberglass suspended ceiling tiles. They are somewhat rigid and easy to cut to fit. They hold their shape better than fiberglass bats will over time in a shaking, vibrating vehicle.
Styrofoam will squeak and drive you crazy.

**Q: Does it not release any smell or odor what so ever, if parked outside all day in the scorching tropical heat from the Caribbean?**
A: unfortuanty I have NO IDEA how hot the Caribbean sun gets.....We never noticed qy smell ...

**Q: Do they have an unbranded version? considering a product like this for a jeep hard top and would much rather have a solid black appearance.**
A: The fiberglass is yellow and the plastic covering on all of it I've seen is white/off white.  I believe you would need a thin plastic or cardboardy headliner.  I haven't used this on a jeep.
