Posted by D. Brian Smith on Apr 24th 2024

Flatline Barriers provides the best sound and heat elimination solutions for American pony cars and muscle machines. Flatline Barriers insulation kits are available for a wide range of GM, Plymouth, Dodge, Ford, and Mercury vehicles. "Where heat and sound meet their maker," is Flatline Barrier's slogan. Their tagline doesn't just ring true... More accurately, it ever so softly thuds true. Follow along and you'll find out why.


A Subtle Low Noise Is Much Better Than a High Percussion Cymbal Jingle Jangle

You don't want the inside of your muscle machine sounding like someone's banging a giant gong over and over. No matter how much horsepower and torque your engine makes, you don't want your teeth's fillings rattling loose every time you mash the throttle pedal and take your car for a cruise. It's much more pleasing to the interior's occupants if the noise is a refined and healthy rumble as opposed to a raucous, instant hearing loss sort of din.


Flatline Barriers To the Rescue

Flatline Barriers is comprised of an aluminum thermal barrier that deflects radiant heat. In tests with a heat gun and a digital thermometer, the Flatline Barriers covered portion of the body panel showed a minimal increase in temperature (one or two degrees higher in Fahrenheit), while the uncovered side of the panel's temperature increased more than 100%. There's also an ultra-lightweight foam section that absorbs and greatly diminishes unwanted noise, vibration, and resonance. In both low to mid frequency and mid to high frequency sound elimination testing versus competitors, Flatline Barriers insulation kits are over twice as effective in absorbing unwanted sound, rattling, and reverberation.

Flatline Barriers products are superior to other competing products as shown by how well they absorb unwanted noise and heat. The insulation kits are also a breeze to install. For an easy peel and click installation, there's an adhesive backing at the bottom of the Flatline Barriers product.


Super Easy to Install

A couple things you need to be sure of before you peel and stick is to make sure the barrier panel is lined up exactly where you want to place the panel. You'll also want to be sure the surface that you're applying the barrier sheets to is free of dirt and grime. The self-adhesive backing is very sticky, so it's very hard to unstick a panel that has already been installed. For this reason, you'll also want to precut any openings for bolts or other items that you need access to like a transmission tunnel or an access panel in your floorboard.
