Covering 2.23㎡, it delivers superior soundproofing and reduces heat transfer by 98%, ensuring a quieter, cooler driving experience. Designed for easy installation on multiple vehicle parts, it offers durable, anti-extrusion performance and a universal fit that won’t compromise your car’s space. ## Description Our self-adhesive car acoustic insulation is the practical solution for car soundproofing and rear thermal insulation of the vehicle. The 4 mm high density closed cell foam insulating sheet is bitumen free and aluminum-free and is ideal for DIYers and car lovers who want to reduce driving noise and improve comfort for a long time. The car acoustic insulation dampens air noise from the street, tyres and engine and improves thermal insulation: in summer the cabin remains cooler and in winter warmer. Thanks to the self-adhesive coating, the film is quickly and easily installed: cut the film to the desired size, remove the protective paper and press firmly. For optimal adhesion, clean and degrease the surface thoroughly before installation. Available in different sizes and formats: from compact single rolls for partial equipment to large rolls and pre-cut plates for complete renovations. The waterproof and ageing resistant foam sheet retains its insulating properties permanently under normal vehicle use. Note: This product is a sheet of acoustic absorbing foam for thermal and acoustic insulation, not a butyl anti-vibration sheet. ## Features - **Effective acoustic and thermal insulation for vehicles** Our self-adhesive heat insulation film made of 4 mm high-density closed-cell foam significantly reduces street, tire and engine noises and reliably insulates against heat and cold. Depending on the variant, you will receive one or more pre-cut rolls or plates to equip your vehicle to measure. - **Stable and long-lasting material** Compared to low-quality foams, our insulation film stands out for its high pressure resistance: it retains its shape and insulating effect even under continuous load and vibrations while walking. The high-quality adhesive layer grips firm and durable, and the protective paper removes cleanly without tearing. - **Easy DIY installation, no additional glue** The self-adhesive car soundproofing installs without complications: cut the film to the desired size with a utility knife, remove the protective paper and press it on the clean, dry surface. No more tools or adhesives needed. - **Versatile use throughout the vehicle** The thermal insulation car is ideal for doors, trunk, passenger compartment floor, roof, bonnet inner face and wheel arches. Compatible with cars, SUVs, vans, motorhomes and industrial vehicles of the usual classes. - **Reliable AggSound Service** We offer high-quality sound and thermal insulation products at fair prices.

What's the best way to install it for maximum results?** A: 1.Remove & Clean: Take off interior panels; clean and dry surfaces 2.Cut to Fit: Pre-cut insulation for doors, floor, and roof 3.Apply & Seal: Peel, stick, then seal seams with foil tape (sold separately) 4.Reinstall: Replace all interior components **Q: What's the difference between Aluminum Foil and Closed-cell Foam?What are the best sound deadening solutions for sound?** A: 394mil Aluminum Foil excels in heat blocking. 157mil Closed-cell Foam (higher density) is better for soundproofing. For best results: combine 157mil foam with Butyl Sound Deadener (sold separately) to kill vibration and block noise effectively. **Q: How do I properly install the Butyl + 157mil High-Density Closed-cell Foam combination?** A: 1. Remove, Clean & Cut. 2. Apply butyl sheets(50–60% coverage is optimal), damping vibration, reducing low-frequency noise. 3. Install foam over butyl. Effectively blocks mid-high frequency noise. 4. Check. This combo ensures optimal noise reduction. **Q: How do sound deadening materials work to reduce noise? Can it reduce road noise? Can it be used on car doors?** A: Yes, Closed-cell Foam reduces road noise through:1.Sound absorption (energy to heat conversion) 2.Acoustic impedance reflection 3.Mass law blocking of mid-high frequencies. Its structure effectively reduces road/wind noise transmission into cabin. **Q: Does it require any special tools for the installation? Is a roller necessary?** A: Basic tools: gloves, utility knife, measuring tape. A roller (sold separately) is highly recommended to ensure proper adhesion of butyl/foam. Aluminum foil tape is essential for sealing seams. Keeping surfaces clean is crucial for optimal results. ## Frequently Bought Together - AggSound 157mil 24sqft Roll Pack Sound Deadener for Cars-Auto Closed Cell Foam Noise Deadening Material-Heat Shield Insulation Dampening Mat - 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.com.ar/products/516629410-4-mm-280-x-40-cm-acoustic-insulation-car-self](https://www.desertcart.com.ar/products/516629410-4-mm-280-x-40-cm-acoustic-insulation-car-self) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-03*
