Description
Multi-layer composite noise barrier SGM Silton 4mm is a soundproofing membrane that combines a layer of thermal and noise-absorbing PE foam with a damping membrane. Its multilayer design effectively reduces mid-frequency noise while keeping the material very thin.
Closed-cell foam with MLV (polymer) SGM Classic Silton 4mm is a classic multi-layer noise barrier from the SGM Classic line. It combines two functional layers into a single high-performance material:
- Face layer — Middle-Heavy Mass Loaded Vinyl (MLV) (polymer core) for optimal sound blocking across a broad frequency range.
- Inner layer — a resilient closed-cell polyethylene foam layer for thermal insulation and additional sound absorption.
- Mounting layer — a waterproof adhesive with siliconized release paper, which facilitates installation.
The waterproof adhesive layer ensures strong adhesion of materials even when exposed to moisture and harsh weather conditions. The material maintains its performance in temperatures ranging from -40°C to +90°C. SGM Silton offers an optimal balance of thickness and functionality, providing high-quality soundproofing in confined spaces.
Advantages
- Maximum efficiency with minimal thickness;
