It delivers up to 85% heat insulation and superior noise reduction, making it perfect for under carpets, door liners, and headliners. Lightweight and flexible, it installs easily and enhances comfort by blocking heat, cold, and unwanted noise, ensuring a 'like new' driving experience. ## 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: 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 - A multi-layered, lightweight, high-tech under-carpeting composite material offering maximum thermal insulation - Extremely flexible and perfect for trucks, door liners, rear decks, head liners and more - Insulates up to 85% of unwanted heat; creates a comfortable interior at any temperature - Use alone, or as an added sound decoupler with Boom Mat vibration dampening material - Superior noise absorption, preventing the rattles and squeaks to ensure a "like new" driving experience ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005Q583BC | | Best Sellers Rank | #79,848 in Automotive ( See Top 100 in Automotive ) #16 in Automotive Flooring & Carpeting #172 in Automobile Insulation | | Brand | Design Engineering | | Brand Name | Design Engineering | | Color | Regular | | Customer Reviews | 4.7 out of 5 stars 265 Reviews | | Global Trade Identification Number | 00607078501103 | | Item Dimensions L x W | 25"L x 6"W | | Item Thickness | 1 Inches | | Item Weight | 3.3 Pounds | | Manufacturer | Design Engineering | | Manufacturer Part Number | 50110 | | Material | Fiberglass | | Material Type | Fiberglass | | Model Number | 50110 | | Number of Items | 1 | | Part Interchange Info | 050110 | | Product Care Instructions | Spray down with a garden hose and allow to air dry | | Product Dimensions | 25"L x 6"W | | Shape | Rectangular | | Size | 6" x 2'1" (Rectangular) | | Surface Recommendation | Hard Floor, Tile, Carpet | | UPC | 607078501103 | | Unit Count | 11.66 Square Feet | ## Product Details - **Brand:** Design Engineering - **Color:** Regular - **Material:** Fiberglass - **Product Dimensions:** 25"L x 6"W - **Size:** 6" x 2'1" (Rectangular) ## Images ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 24" (11.6 sq. ft.) - Image 1](https://m.media-amazon.com/images/I/71fnuIdV7LL.jpg) ![Design Engineering Under Carpet Lite | Heat & Sound Insulation Sheet | Lightweight Multi-Layer Composite | 70" x 24" (11.6 sq. ft.) - Image 2](https://m.media-amazon.com/images/I/61LOR69jSCL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Frequently Bought Together - Design Engineering 050110 Under Carpet Lite 24" x 70" Sound Absorption and Insulation (11.6 sq. ft.) - LUMITECO Bearings Equipped Automotive Car Audio Sound Deadening Application Wheel Roller, Heat Abatement Mat Wallpaper Application PU Smoothing Tool Seam Roller - Siless 80 mil (2mm) 36 sqft (3.4 sqm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (36 sqft) --- ## 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.co.uk/products/12492787-design-engineering-under-carpet-lite-heat-and-sound-insulation-sheet](https://www.desertcart.co.uk/products/12492787-design-engineering-under-carpet-lite-heat-and-sound-insulation-sheet) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-13*
