SoundLag™ 4525C Acoustic Pipe Lagging

SoundLag™ 4525C Acoustic Pipe Lagging

Regular price $110.50

Pipe lagging is a pipe insulation product designed to reduce noise emitted from ductwork, valves, fan housings and pipes in all types of building projects. 

Soundlag™ is a range of high-performance acoustic lagging products developed by Pyrotek to reduce waste water noise from pipes, fan housings, and ducting within building and industrial environments. Soundlag is a composite product consisting of reinforced foil faced mass loaded vinyl (MLV) and a decoupling layer of either foam or glass wool.

The highly fexible and dense MLV layer provides outstanding sound reduction, whilst the decoupling foam breaks the vibration path between the substrate and the mass barrier. The aluminium foil covering ofers fame-resistant properties, while also providing a seamless bonding surface when used with Pyrotek’s Tape ALR. Unlike other noise barriers, Soundlag’s unique fexibility can be easily cut and formed to any shape or bend. The pliability achieves an excellent acoustic seal by eliminating potential fanking noise through the joints and overlaps.

Australia made, Soundlag has been independently tested, backed with over 20 years manufacturing. Maintaining consistent performance and trustworthy quality, Soundlag guarantees quieter ducts and pipes.
