Acoustic Lagging

AKINCO’s acoustic lagging and wraps are engineered to minimize noise transmission through pipe walls and enhance sound absorption in enclosed spaces. These advanced insulation solutions offer highly effective reduction of radiated noise using a loaded vinyl noise barrier designed for both industrial and commercial environments.

The lagging system consists of a loaded vinyl noise barrier with a scrim-reinforced aluminum foil facing on one side, bonded to a 1-inch thick sound-absorbing decoupler. This multi-layered system provides outstanding thermal and acoustic insulation for pipes and ductwork, helping maintain quieter and more energy-efficient facilities.

For the insulation of soil, waste, sanitary drainage, and water pipes, AKINCO recommends acoustic lagging made with isolation foam and a mass barrier, achieving a total weight of at least 5 kg/m². The lagging material should be precisely cut to fit around all piping and designed to overlap at joints. All seams must be sealed using high-quality foil tape to ensure long-lasting acoustic integrity and resistance to environmental conditions.

This high-performance composite lagging system is ideal for reducing noise from pipes, valves, fan housings, and ducts in a wide range of building types. It is suitable for both new installations and retrofit projects.

Description

Acoustic Lagging

AKINCO acoustic lagging and Wraps are designed to block noise that transmits through the walls of the pipe or as well as to increase the sound absorption in the cavity. Designed to offer significant reduction of radiated noise, it consists of a loaded vinyl noise barrier with a scrim reinforced aluminum foil facing on one side bonded to a 1” sound absorbing decoupler. Our pipe and duct wrap offers excellent thermal and acoustical performance.
The sound insulation of soil, waste, sanitary drainage and water pipes shall be from acoustic lagging manufactured with acoustic isolation foam and a mass barrier to a total weight of not less than 5kg/m2.It should be cut to size to neatly fit all pipe work, and incorporate overlaps on all joins. All joins shall be secured with an appropriate foil tape. 

The unique construction offers dual benefits: it acts as both a noise barrier and a noise absorber. The dense, flexible vinyl layer effectively blocks airborne sound transmission, while the decoupling layer interrupts vibration paths, significantly lowering structural noise. The outer aluminum foil not only enhances durability and fire resistance but also creates a clean, smooth finish that facilitates easy joining with adjacent sheets. This versatile solution ensures optimum acoustic performance, mechanical strength, and ease of installation across a broad spectrum of applications.
