## Overview

Design Engineering’s Under Carpet Lite is a 1/2" thick, multi-layer polyester/fiberglass composite designed for superior sound absorption and thermal insulation. Lightweight and flexible, it blocks up to 85% of heat transfer while eliminating noise, rattles, and squeaks. Perfect for automotive interiors like door liners and headliners, it installs easily and enhances both comfort and vehicle value.

## Description

Boom Mat Under Carpet Lite is a superior sound decoupling material for those hard to cover areas like door liners, rear decks, headliners and more. Under Carpet Lite, (UC Lite) is a 1/2" thick multi-layer, high tech composite material designed to be extremely flexible and easy to install. UC Lite offers maximum thermal insulation in a lightweight padding that provides less heat transfer in the summer while protecting against the transfer of cold air in the winter. UC Lite is also equally effective as a sound deadener that prevents the transfer of noise, including rattles and squeaks to ensure a "like new" driving experience and add longstanding value to your investment. The multilayer polyester/fiberglass composite material offers unmatched thermal and acoustic protection in an extremely flexible light weight package. Boom Mat UC Lite is recommended for use either alone, or as an added sound decoupler with Boom Mat vibration dampening material. It can be installed under carpet, behind door panels, under headliners, on fire walls, or any interior location. To install, simply fasten mechanically to the area, or tack in place with Boom Mat's Hi-Temp Spray Adhesive (# 010490, sold separately). Hi-Temp Spray Adhesive works well on both vertical and overhead surfaces. UC Lite can also be used as a second layer over Boom Mat Damping Material for superior light-weight thermal insulation.

Review: Step Way Above Jute Padding - Used in trunk and under several areas of carpet in 78 Firebird. Way better than jute padding. Can be difficult to cut with just a razor knife - I used a razor knife to "score" through one layer and then sharp shears to make the cuts.
Review: Cool toes would buy rad stuff - Before I installed this under-carpet heat shield, driving my car felt like sitting on a stove set to medium-well. My floorboards were cooking my feet faster than a hibachi grill at a family dinner. But after slapping this magical layer under my carpet? Total game-changer. This heat shield doesn’t just block heat—it straight-up tells it to pack its bags and leave. Now, my interior is cooler than an arctic breeze, and my feet no longer feel like they’re auditioning for a spot in the lava-walking Olympics. Bonus: It also muffled some of the road noise, so now I can hear my tunes without my car sounding like a tank rolling over gravel. Installation was easy—cut to size, slap it down, and boom, instant comfort. 10/10, my feet are finally free from floorboard hell, and I can drive without feeling like a baked potato. Highly recommend!

## Questions & Answers

**Q: How well does this mat actually block or absorb sound? I would use this inside my car, underneath the factory carpeting.**
A: Vaughn, I just finished up a very intensive project on my C4 Corvette ZR-1. Not satisfied with the results last year, I went back at it with an actual sound barrier.  The DEI Under cover light, while being a good upgraded replacement for jute padding, will not block any sound.  If you buy it with this intent, you will be disappointed.  You need an actual sound barrier.  The best "barrier" is mass loaded vinyl or "MLV".  The negative is that this adds weight and most is available at 1 lb per square foot.  Go with this if weight is not a concern.  For my project, I went with MLV in the "light" version at .5 lb per square foot.  Cascade Audio Engineering had the product you want and I see that it is even available right here on Amazon.  It is called VB-4.5 (type in Cascade Audio Engineering VB-4.5.  Also available in the heavier VB-4.  Boom Mat has its benefits, but sound control isn't one of them.  Don't believe me?...Lay it out on the table and have someone call your cell phone underneath it...hardly ANY if NO reduction in the sound of your phone ringing.  Good Luck.

**Q: which side goes down for car floor pan installs?**
A: The top side is a light gray as shown.  The bottom side is white.

**Q: need something for the floor of my 2018 jeep JKu  to kill the heat, i dont care about the noise, what does the manufacturer suggest?**
A: I installed this in my Jeep about 2 years ago. It did help with heat and noise. It is also holding up well. I recommend this product.

**Q: can this be used on house floors**
A: That's far too vague to answer correctly. If you are thinking carpet padding I would stick with regular pad - this would probably break down in high traffic areas. In terms of soundprooofing residential applications normal batt type fiberglass insulation and blown/spray cellulose will outperform this product.
