It delivers superior thermal insulation and noise reduction, making your vehicle interior cooler in summer, warmer in winter, and significantly quieter. Lightweight and flexible, it installs easily and outperforms traditional jute padding, earning high customer ratings and trusted by automotive enthusiasts. ## Description Engine heat, exhaust heat, road heat — they all find their way into the cabin through the floor, firewall, and body panels. So does road noise. Under Carpet Lite™ was designed to deal with both at once.It's a ½" thick multi-layer composite built from polyester and fiberglass — flexible enough to conform to complex surfaces, light enough not to add meaningful weight, and effective enough to work as both a thermal barrier and a sound decoupler. At approximately 0.23 lbs per square foot across a 70" x 72" sheet (35 sq. ft.), this is the largest UC Lite size available — ideal for full floor coverage, complete firewall installs, or builds where you want to treat multiple areas in one go without piecing together smaller sheets.On the thermal side, UC Lite reduces heat transfer from hot underbody surfaces in summer and blocks cold air intrusion in winter — keeping interior temperatures more consistent and comfortable year round. On the acoustic side, the multi-layer construction decouples road noise, rattles, and squeaks before they reach the cabin, adding a noticeably quieter, more refined feel to the driving experience.Installation is straightforward. Cut to shape, then fasten mechanically or bond in place with DEI Hi-Temp Spray Adhesive, which holds on both vertical and overhead surfaces. Under Carpet Lite™ works well on its own or as an added sound decoupler alongside Boom Mat™ vibration dampening material for a more complete build.Floor pans, firewalls, transmission tunnels, door panels, trunk floors, headliners, kick panels, rear quarter panels — if heat or noise is getting in, this is where you start. Review: Noise and heat barrier - Worked very well under carpet in a c10. Keeps noise and heat out of cab. Excellent product. 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! ## Features - Fit type: Universal Fit - Light weight - Superior noise barrier - Perfect to use over Boom Mat ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008NF84J8 | | Best Sellers Rank | #60,288 in Automotive ( See Top 100 in Automotive ) #15 in Automotive Flooring & Carpeting | | Brand | Design Engineering | | Brand Name | Design Engineering | | Color | Grey | | Customer Reviews | 4.7 out of 5 stars 265 Reviews | | Global Trade Identification Number | 00607078501134 | | Included Components | Per Item Description | | Item Dimensions L x W | 18"L x 15"W | | Item Thickness | 1 Inches | | Item Weight | 4.75 Kilograms | | Manufacturer | Design Engineering | | Manufacturer Part Number | 50113 | | Manufacturer Warranty Description | 30 days. | | Material | Polyester | | Material Type | Polyester | | Model Number | 50113 | | Number of Items | 1 | | Part Interchange Info | 050113 | | Product Care Instructions | Dry Clean Only | | Product Dimensions | 18"L x 15"W | | Shape | Rectangular | | Size | 1'3" x 1'6" (Rectangular) | | Surface Recommendation | Hard Floor, Tile, Laminate | | UPC | 607078501134 | | Unit Count | 35.0 Square Feet | ## Product Details - **Brand:** Design Engineering - **Color:** Grey - **Material:** Polyester - **Product Dimensions:** 18"L x 15"W - **Size:** 1'3" x 1'6" (Rectangular) ## Images ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 72" (35 sq. ft.) - Image 1](https://m.media-amazon.com/images/I/711RFsoP93L.jpg) ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 72" (35 sq. ft.) - Image 2](https://m.media-amazon.com/images/I/81llTdjEY2L.jpg) ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 72" (35 sq. ft.) - Image 3](https://m.media-amazon.com/images/I/61dca7Xq-8L.jpg) ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 72" (35 sq. ft.) - Image 4](https://m.media-amazon.com/images/I/51iLdfcPYJL.jpg) ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 72" (35 sq. ft.) - Image 5](https://m.media-amazon.com/images/I/61LOR69jSCL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Noise and heat barrier *by J***H on May 2, 2025* Worked very well under carpet in a c10.

Highly recommend! ### ⭐⭐⭐⭐⭐ Step Way Above Jute Padding *by R***L on March 11, 2026* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/10246572-design-engineering-under-carpet-lite-heat-and-sound-insulation-sheet](https://www.desertcart.de/products/10246572-design-engineering-under-carpet-lite-heat-and-sound-insulation-sheet) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-11*
