Tecsound FT55 ALU Acoustic Pipe Lagging — Duct Wrap & Pipe Soundproofing
Tecsound FT55 ALU acoustic pipe lagging is a professional grade duct wrap composite designed to significantly reduce noise transmission from soil pipes, drainage pipes, air conditioning ducts and industrial pipework. Combining a porous mineral wool absorbing layer with a high-density viscoelastic soundproofing membrane and reinforced aluminium foil outer facing, it delivers up to 25dB sound reduction on pipework in a single, easy to apply product.
What Makes Tecsound FT55 ALU the Preferred Acoustic Pipe Lagging
High Performance Sound Reduction
Tecsound FT55 ALU works through a combination of sound absorption and sound insulation. The porous mineral wool layer absorbs sound energy while the dense viscoelastic membrane blocks transmission — together delivering up to 25dB reduction in airborne sound from pipework. This dual action makes it one of the most effective solutions available for soil pipes and drainage systems in residential and commercial buildings.
Flexible and Easy to Apply
Unlike rigid lagging products, Tecsound FT55 ALU is highly flexible and adapts to round, square and irregular pipe profiles without the need for specialist pieces at bends and connections. It can be cut to size on site and wrapped directly around pipework, ensuring continuous insulation with no weak points.
Aluminium Foil Facing
The reinforced aluminium foil outer face provides durability, heat resistance and a clean professional finish. Joints are sealed with aluminium tape to eliminate gaps and maintain full soundproofing performance throughout the installation.
Fire Rated
Tecsound FT55 ALU carries a Fire Rating of B — s1, d0, making it suitable for use in buildings where fire performance of insulation products is a specification requirement.
Cold and Heat Resistant
Suitable for use in temperatures from -10°C to +70°C, it performs reliably across a wide range of environments including cold pipe runs, hot water systems and external applications.

Installation
Measure the circumference of the pipe and add 50mm for overlap. Cut strips of no more than 1–1.2m to make handling easier. Wrap the product around the pipe with the mineral wool facing the pipe surface, overlapping in the longitudinal direction. Secure with cable ties every 25–30cm and seal all joints with aluminium tape to maintain full acoustic performance.
