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.
Using the Siless 4 mm foam has really helped with sound reduction in my sedan. I've tested it on long drives and the difference is clear. I appreciate the closed-cell design, and it fits well in my vehicle’s interior. Definitely recommend for anyone wanting a quieter ride!

Decent soundproofing but tough to install
I bought this Siless sound deadening mat for my project car. The insulation is solid, and it does help with heat, but I found the installation a bit tricky. The instructions weren't very clear, which made it a bit frustrating. Still, it works well once you get it down!

Great for my car audio upgrade
I recently installed the Siless liner in my car, and I’m really impressed with the 157 mil thickness. The sound deadening is amazing, and it reduced road noise significantly. Plus, it’s super easy to work with, covering a good 51 sqft area was a breeze!

Packaging was damaged, but product works
Ordered the Siless deadening mat and it arrived with a bit of damage to the packaging, which was disappointing. However, the foam itself is effective at sound insulation and I haven't had any issues with performance. Just wish shipping had been better!
