Soundlag Acoustic Pipe & Duct Lagging – High-Performance Composite Insulation Noise Control for HVAC, Plumbing & Mechanical Services
Soundlag is a premium acoustic lagging product engineered to minimise noise transmission from pipes, valves, ducts, and fan housings in commercial, industrial, and residential buildings. Combining a dense mass-loaded barrier with a decoupling foam or fibre layer, Soundlag delivers superior acoustic performance in ceiling voids, plant rooms, and exposed services.
Key Features
BCA compliant: meets Building Code of Australia F5.6 and achieves a zero rating under AS1530.3
Superior noise reduction: reduces noise levels by up to 5 dB(A) more than standard low-noise pipe solutions
Flexible barrier layer: high-mass vinyl layer for optimal sound transmission loss
Decoupling layer options: foam, polyester, fibreglass, or quilted glass wool from 6 mm to 50 mm thick
Fire-resistant foil facing: protects insulation and simplifies sealing
Multiple finishes available: reinforced aluminium foil, black foil, or white anti-glare foil for visible ceiling spaces
Ideal Applications
HVAC & ducting: use around fans, ducts, and vents to block breakout noise—pair with Wavebar Sound Barrier in adjacent enclosures
Plumbing & services: wraps around waste and water pipes to reduce noise transmission through walls and ceilings
Plant rooms & equipment housing: suitable for gensets, chillers, and pump enclosures. Combine with Sorberfoam Acoustic Foam for internal sound absorption
Ceiling spaces: anti-glare foil finish suitable for visible soffits and exposed service zones
Cabfoam Acoustic Foam – perforated vinyl-faced acoustic foam for adjacent enclosures and cavity absorption
Sorberbarrier – for wall-mounted noise control in rooms adjacent to services
Soundlag provides a professional-grade, multi-layered solution for blocking unwanted mechanical and pipework noise. It is ideal for engineers, HVAC installers, and acoustic contractors looking for reliable, compliant insulation.
