Generators and engines are loud. They also need weather protection, safe access, and good airflow to run well. An acoustic canopy solves all four problems at once. It is one of the most practical acoustic solution products used across power generation, marine, and industrial sites today.
What Is an Acoustic Canopy?
An acoustic canopy is a steel enclosure built around a generator or engine. It reduces noise, protects the equipment from rain and wind, and keeps staff safe from moving parts. IMS builds these canopies from 1.6 mm Zintec steel, formed into panels and welded into a rigid structure. A heavier steel gauge is used where extra strength or sound reduction is needed.
How Acoustic Canopies Reduce Noise
The inside of the canopy panels is lined with 50mm resin-bonded mineral fibre, faced with 1.0mm galvanised perforated steel. This layer absorbs sound energy before it can escape the enclosure. Acoustic splitters and baffles are also fitted to control airflow while still allowing cooling air to pass through. This means the generator stays cool and quiet at the same time.
Airflow and Access Features
A generator needs a steady flow of air to cool down and to support combustion. IMS canopies use mesh or fixed weather louvres to bring air in safely, without letting noise escape. Access doors are fitted on the sides and rear for maintenance. Viewing windows can also be added, so staff can check the control panel without opening the canopy.
Fixed vs Demountable Canopies
Some sites need a permanent structure. Others need one that can be moved or rebuilt in a new location. For these cases, IMS offers demountable canopies. Acoustic panels are bolted to hollow box steel frames, and the frames are bolted together on site. This makes the canopy easy to transport and reassemble. All panels are made from non-combustible material and meet Class 1 Spread of Flame standards, so fire safety is not a concern.
Where Acoustic Canopies Are Used
Acoustic canopies are common in:
- Power generation sites
- Data centres
- Hospitals
- Petrochemical plants
- Marine and offshore equipment rooms
Each site has different noise limits and space constraints, so canopies are usually custom-designed around the engine size, required airflow, and target noise level in decibels.
Why This Matters for Facility Managers
Noise complaints, health and safety rules, and planning restrictions all push facilities toward better noise control. An acoustic canopy lets a site run large diesel or gas generators without breaching local noise limits or putting staff at risk. It also protects expensive equipment from weather damage, which reduces long-term maintenance costs.
Frequently Asked Questions
What is an acoustic canopy used for? It reduces noise from a generator or engine while also protecting it from the weather and giving staff safe access.
What material are acoustic canopies made from? IMS canopies use Zintec steel panels lined with resin-bonded mineral fibre and perforated galvanised steel.
Can acoustic canopies be moved? Yes. Demountable canopies are built with bolted panels and steel frames, so they can be dismantled and rebuilt at a new site.
Are acoustic canopies fire safe? Yes. All panels are made from non-combustible materials and meet Class 1 Spread of Flame requirements.
