Lightweight at 0.23 lbs per sq ft, it flexes to fit complex surfaces and installs easily with mechanical fasteners or adhesive. Ideal for automotive interiors, it enhances cabin comfort by blocking heat in summer, cold in winter, and decoupling sound for a quieter drive. ## Description Engine heat, exhaust heat, road heat β€” they all find their way into the cabin through the floor, firewall, and body panels. So does road noise. Under Carpet Liteβ„’ was designed to deal with both at once.It's a Β½" thick multi-layer composite built from polyester and fiberglass β€” 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 48" sheet (23.3 sq. ft.), you get serious coverage without the bulk of traditional insulation materials.On the thermal side, UC Lite reduces heat transfer from hot underbody surfaces in summer and blocks cold air intrusion in winter β€” 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 Liteβ„’ works well on its own or as an added sound decoupler alongside Boom Matβ„’ vibration dampening material for a more complete build.Floor pans, firewalls, transmission tunnels, door panels, trunk floors, headliners, kick panels, rear quarter panels β€” if heat or noise is getting in, this is where you start. ## Features - HEAT IN SUMMER, COLD IN WINTER β€” BLOCKED YEAR ROUND β€” Under Carpet Lite is a Β½" thick multi-layer polyester/fiberglass composite that cuts heat transfer from engine bays, exhaust, and road surfaces in summer while keeping cold air out in winter β€” giving you a more comfortable interior without adding meaningful weight to your build - QUIETER CABIN, BETTER DRIVE β€” Just as effective as a thermal barrier, UC Lite decouples sound and prevents the transfer of road noise, rattles, and squeaks from working their way into the cabin. The result is a noticeably quieter, more refined driving experience whether you're daily driving or building for shows - LIGHTWEIGHT WHERE IT COUNTS β€” At approximately 0.23 lbs per square foot, Under Carpet Lite delivers serious thermal and acoustic performance without the bulk or weight penalty of heavier insulation materials β€” a genuine advantage in performance and high-output builds where every pound matters - FLEXIBLE ENOUGH TO GO ANYWHERE β€” The multi-layer composite is designed to be extremely flexible, making it easy to work into tight, curved, and irregular surfaces. Install under carpet, behind door panels, under headliners, on firewalls, transmission tunnels, trunk floors, inner fender wells, kick panels, and more - EASY TO INSTALL, WORKS ALONE OR AS PART OF A SYSTEM β€” Fasten mechanically or bond in place with DEI Hi-Temp Spray Adhesive β€” works on vertical and overhead surfaces. Use UC Lite on its own or pair it with Boom Mat vibration dampening material for a complete, layered sound and thermal solution ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005Q584IY | | Best Sellers Rank | #67,482 in Automotive ( See Top 100 in Automotive ) #16 in Automotive Flooring & Carpeting | | Brand Name | Design Engineering | | Color | Multi Color | | Customer Reviews | 4.8 4.8 out of 5 stars (269) | | Global Trade Identification Number | 00607078501110 | | Included Components | Under Carpet Lite 48" x 70" | | Item Dimensions L x W | 70"L x 48"W | | Item Thickness | 0.5 inches | | Item Type Name | Under Carpet Lite (UC Lite) | | Item Weight | 6 pounds | | Manufacturer | Design Engineering | | Manufacturer Part Number | 50111 | | Manufacturer Warranty Description | Please contact us if you experience any issues within 30 days of receipt. | | Material Type | Polyester | | Model Number | 50111 | | Number of Items | 1 | | Part Interchange Info | 050111 | | Product Care Instructions | Spot clean with mild detergent, spray down with a garden hose | | Shape | Rectangular | | Size | 4' x 5'10" (Rectangular) | | Surface Recommendation | Hard Floor | | UPC | 607078501110 | | Unit Count | 23.3 Square Feet | ## Product Details - **Brand:** Design Engineering - **Color:** Multi Color - **Material:** Polyester - **Product Dimensions:** 70"L x 48"W - **Size:** 4' x 5'10" (Rectangular) ## Images ![Under Carpet Lite, 4' x 5'10" - Image 1](https://m.media-amazon.com/images/I/711RFsoP93L.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. ## Frequently Bought Together - Design Engineering 050111 Under Carpet Lite 48" x 70" Sound Absorption and Insulation (23.3 sq. ft.) - LUMITECO Bearings Equipped Automotive Car Audio Sound Deadening Application Wheel Roller, Heat Abatement Mat Wallpaper Application PU Smoothing Tool Seam Roller - DEI - 13.3 oz.
