Soundlag®

Acoustic Pipe and Duct lagging

Soundlag® Acoustic Pipe Insulation

Soundlag® is a high-performance acoustic lagging system designed to reduce noise transfer from pipework, ducting, and mechanical services in commercial, industrial, and multi-residential buildings.Constructed as a composite acoustic wrap, Soundlag® combines a dense mass layer with a decoupling layer to effectively reduce both airborne and structure-borne noise.
This makes it ideal for applications where noise control and compliance are critical.The flexible wrap format allows for easy installation on pipes, valves, and ductwork, while the reinforced foil facing provides durability and a clean, professional finish. Soundlag® is widely used in plumbing, HVAC systems, plant rooms, and service risers to improve overall acoustic performance.Designed for demanding environments, Soundlag® offers a reliable solution for managing noise in modern building systems.

Applications: Commercial, HVAC
