Noise Stop - Patented Noise Reduction Technology

Welcome to your premier UK destination for Noise-Stop®, the patented universal soundproofing system specifically designed for manholes, pit lids, and drain covers. As the official UK distributor, our mission is to bring this "smart solution for a better life" to residential and urban areas across the country, tackling the persistent problem of noise pollution caused by traffic.
The Problem We Solve
We understand the frustration caused by a noisy manhole cover that makes life impossible. That familiar, annoying metallic "clank" occurs every time a vehicle passes over a manhole, caused by the tilting of covers and grates as they strike their frames. This constant noise disrupts sleep, reduces urban acoustic comfort, and affects the quality of life for both residents and their pets.
The Noise-Stop® Solution
Noise-Stop® is a unique invention developed and patented by ITG SPA, an industry leader in elastomer-based gaskets and liquid silicone technology. This system effectively compensates for the gaps and deformations between covers and frames.
Our Product Range
We provide tailored solutions based on the specific wear and traffic conditions of your location:
• Light Noise Series: Ideal for residential areas with light daily traffic and slight cover defects.
• Medium Noise Series: Designed for urban and extra-urban roads with medium to high vehicle and truck traffic.
• Heavy Noise Series: The solution for "enormous problems of tilting" where frames and lids are highly deformed and require high vertical and lateral thickness.
Our Commitment
As your UK distributor, we are committed to providing not just a product, but a complete consultancy service. Whether you are a homeowner looking for peace and quiet or a contractor managing street maintenance, we offer the expertise to identify the best soundproofing scheme for any situation
1. Patented Noise Reduction Technology
Noise-Stop® is a unique and patented solution specifically designed to tackle the common problem of urban noise pollution. It effectively eliminates the loud, metallic "clacking" sound caused by vehicles passing over loose manhole covers and drains by compensating for the gap between the frame and the cover.
2. Universal and Versatile Design
One of the product's strongest selling points is its universal compatibility. Thanks to its versatile shape, it can be applied to any manhole cover or drain, whether it is round, square, or triangular. It is designed to adapt to almost every existing configuration on the market.
3. Improved Quality of Life and Comfort
By reducing urban noise, the product significantly increases acoustic comfort in residential areas. This improvement in the environment benefits both human residents—allowing for a quieter life and "peaceful sleep"—and their pets.
4. Fast and Simple Installation
Noise-Stop® is designed for ease of use and can be installed in as little as five minutes. Each kit contains at least six units that are easy to apply, making it a "smart" and accessible solution for immediate results.
5. Tailored Solutions for Every Traffic Condition
The product is available in three distinct series to match specific wear and tear levels:
• Light Noise: Ideal for residential areas with light daily traffic and minor defects.
• Medium Noise: Suitable for urban and extra-urban roads with medium to high traffic, including heavy vehicles.
• Heavy Noise: Designed for covers with severe tilting problems and significant deformation that require substantial vertical and lateral spacing.
6. Proven Durability and Industrial Quality
Developed by ITG SPA—experts in elastomer gaskets and liquid silicone technology—the product is built to last. Testimonials indicate that the special rubber units remain effective and durable for over a year, even under continuous traffic. Furthermore, the manufacturing process is backed by ISO 9001 (Quality Assurance) and ISO 14001 (Environmental Assurance) certifications.
7. Professional Reliability
Beyond individual use, the product is trusted by construction professionals who have tested various solutions and found Noise-Stop® to be the most effective and long-lasting option for eliminating manhole noise
