Acoustic Lagging

AcouStick Acoustic Lagging is a flexible composite acoustic wrap designed to reduce noise radiated from pipes, ducts, and mechanical services into occupied or noise-sensitive spaces.

The system combines a limp-mass barrier layer with a decoupling absorptive layer. The heavy barrier helps block airborne sound, while the resilient acoustic layer separates the barrier from the service surface and reduces the transmission of sound and vibration.

These acoustic pipe lagging systems can be installed around existing services and adapted to bends, valves, fittings, and irregular sections, making them suitable for both new construction and retrofit applications.

Why Choose Acoustic Lagging?

Reduces Radiated Pipe & Duct Noise

Acoustic lagging helps reduce airborne noise radiated from pipes, ducts, and mechanical services into surrounding occupied spaces.

Limp-Mass Acoustic Barrier

The mass-loaded vinyl barrier provides a dense, flexible layer that helps resist airborne sound transmission from the service surface.

Decoupling Absorptive Layer

A soft polyester or mineral wool layer separates the barrier from the pipe or duct, helping reduce direct acoustic coupling between the service and barrier.

Flexible Installation

The composite material can be wrapped around bends, valves, joints, fittings, and other service configurations.

Suitable for Retrofit

Acoustic lagging can be applied over existing pipework and ductwork, providing a practical pipe soundproofing solution without replacing the service.

How Does Acoustic Lagging Work?

Acoustic lagging creates a layered acoustic barrier around the pipe, duct, or mechanical service.

The absorptive decoupling layer separates the service from the dense mass-loaded vinyl barrier. The barrier adds mass to the assembly and helps reduce airborne sound radiation, while the decoupling layer limits direct acoustic coupling between the service and outer barrier.

Pipe / Duct Noise → Decoupling Layer → Mass-Loaded Vinyl Barrier → Reduced Noise Radiation

The final acoustic performance depends on the barrier mass, decoupling layer thickness, service dimensions, installation method, seams, joints, bends, and complete acoustic treatment.

Acoustic Performance

Our sound insulation lagging systems are designed to reduce noise radiated from pipes, ducts, and mechanical services.

Actual acoustic performance depends on the service type, barrier weight, decoupling layer, installation method, sealing of joints, and complete lagging configuration.

Acoustic Lagging Applications

Acoustic lagging is suitable for mechanical services where noise radiated from pipes or ducts may affect occupied or noise-sensitive spaces.

Soil & Waste Stacks

Suitable for soil and waste stacks in apartments, hotels, and other multi-storey buildings where plumbing noise can be transmitted into adjacent rooms.

HVAC Ductwork

Can be installed around HVAC ductwork above occupied ceilings to reduce noise radiated from the duct surface into rooms below.

Pump & Chiller Pipework

Suitable for pipework connected to pumps, chillers, and mechanical equipment where operational noise can be transmitted through the service surface.

Plant Rooms

Can be used around selected mechanical services within plant rooms to help control noise radiated into surrounding areas.

Hotels & Hospitality

Suitable for plumbing and HVAC services passing near guest rooms where service noise can affect acoustic comfort.

Residential Buildings

Useful for controlling noise from soil stacks, waste pipes, HVAC services, and other mechanical systems in apartments and residential buildings.

Technical Specifications

Acoustic Lagging Thickness & Configuration

Our HVAC acoustic lagging can be configured according to the service type, available space, required acoustic performance, and installation conditions.

2 mm MLV Barrier

The 2 mm mass-loaded vinyl configuration provides a flexible acoustic barrier with an approximate surface weight of 3.3 kg/m².

3 mm MLV Barrier

The 3 mm configuration provides a higher surface mass of approximately 5 kg/m² and can be selected where additional barrier mass is required.

Decoupling Layer

The acoustic barrier can be combined with a 12–25 mm polyester or mineral wool decoupling layer according to the required system configuration.

Facing Options

Available facing configurations include:

• Plain

• Foil faced

• Reinforced

The appropriate facing can be selected according to the installation environment and required mechanical protection.

Flexible Service Coverage

The material can be wrapped around:

• Straight pipes

• HVAC ducts

• Bends

• Valves

• Fittings

• Mechanical services

The installation should maintain continuous coverage and properly sealed seams to minimise acoustic leakage.

Acoustic Lagging Price in Saudi Arabia

The cost of acoustic lagging depends on several factors, including:

• Pipe or duct dimensions

• Required lagging thickness

• MLV barrier thickness

• Decoupling layer thickness

• Polyester or mineral wool selection

• Total service length

• Number of bends and fittings

• Facing selection

• Installation method

• Required quantity

• Project-specific requirements

Because pipework and ductwork configurations vary from project to project, AcouStick provides project-based pricing for acoustic lagging in Saudi Arabia.

Frequently Asked Questions

What is acoustic lagging?

Acoustic lagging is a composite acoustic wrap installed around pipes, ducts, and mechanical services to reduce noise radiated from their surfaces into surrounding spaces.

How does acoustic pipe lagging reduce noise?

The system combines a dense mass-loaded vinyl barrier with a decoupling absorptive layer. The barrier helps block airborne sound while the soft layer separates it from the service and reduces acoustic coupling.

What is acoustic pipe lagging used for?

It is commonly used to reduce noise from soil and waste stacks, HVAC ductwork, pump and chiller pipework, plant room services, and mechanical systems passing through noise-sensitive areas.

Can acoustic lagging be installed on existing pipes?

Yes. One of the main advantages of acoustic lagging is that it can be applied over existing services, making it suitable for retrofit and renovation projects.

What is the difference between acoustic lagging and thermal pipe insulation?

Thermal insulation is primarily designed to control heat transfer and condensation, while acoustic lagging is designed to reduce noise transmission and radiation from pipes and mechanical services. Depending on the application, separate thermal and acoustic treatments may be required.

What materials are used in acoustic lagging?

The specified construction combines mass-loaded vinyl with a polyester or mineral wool decoupling layer. Different barrier thicknesses and facing options are available.

What thicknesses are available?

The MLV barrier is available in 2 mm and 3 mm, while the decoupling layer can be specified from 12 to 25 mm depending on the required configuration.

How much does acoustic lagging cost in Saudi Arabia?

The price depends on the service dimensions, total length, barrier thickness, decoupling layer, facing, fittings, installation requirements, and project quantity. AcouStick provides project-specific pricing based on the required specification.
