Pyrotek Soundlag - Model 4525C -Acoustic Pipe and Duct Lagging
Soundlag is a high-performance composite acoustic lagging product developed to reduce noise from pipes, valves, fan housings, and ductwork in commercial, industrial and domestic buildings. Soundlag 4525C provides an optimal soundproofing solution for those seeking compliance to BCA (Building Code of Australia) F5.6 requirements for habitable and non-habitable rooms. Based on test results, Soundlag 4525C can offer a significantly higher performance of up to 5 dB(A) compared to low noise pipe products especially in areas with no ceiling or with penetrations.
The highly dense and flexible mass layer provides excellent sound reduction properties, whilst the decoupling layer breaks the vibration path between substrate and the mass barrier, allowing the vinyl external wrap to remain flexible – optimising performance. The external foil facing offers a fire resistant covering and an excellent surface to join adjacent sheets.
Pyrotek® offers varying compositions with barrier weights from 3 kg/m² to 8 kg/m² and the decoupling layer with a choice of plain (4512) or convoluted (4525C) foam, polyester, fibreglass, glass wool or quilted glass wool with thicknesses from 6 mm to 50 mm.
Alternative colour options to the reinforced aluminium facing are black and white foil. These anti-glare foil colours are suitable for exposed ceiling spaces.

HOW TO APPLY SOUNDLAG USING TAPE
- Tape ALR is easy to tear by hand.
- Remove the release liner backing
- Position tape centrally over the sections to be joined and firmly press along the entire tape surface.
- Wipe or rub with firm pressure across the tape with a cloth or blade to smooth out any air bubbles or buckles.
Do not over-stretch the tape when applying, as this will create buckles and voids in the contact area.
All joints along longitudinal pipe sections must be fitted with an overlap of adjoining segments. Overlapped sections must then be taped and sealed with ‘Tape ALR’ or equal. A strip of 30 mm foam can be removed along one or both edges as required to provide for an overlap at joints.
