Exhaust Thermal Insulation Blankets
What are Exhaust Thermal Insulation blankets?
Exhaust Thermal Insulation Blankets (Lagging) are a Mine Site requirement to control surface temperatures of manifolds, turbos, exhaust pipes and mufflers.
There is often confusion about the purpose of Lagging, a lot of people still believe that it is so operators don’t burn their hands if they touch an engine bay. The real purpose of Exhaust Thermal Insulation Blankets is to keep engine bays cool so the machine doesn’t overheat.
Our MineBase Lagging also acts as a protective shield if a fuel line bursts and spills oil throughout the engine bay.
After trialling and testing materials and methods from all over the world, we have produced a solution that balances the optimum levels of Heat Resistance, Thermal Conductivity, Abrasion/ Vibration Resistance, Fluid Repellence, and Incombustibility.
Exhaust Thermal Insulation Blankets are made up of 3 key parts.
Hot Face
We can customise the hot face layer depending on your industry and application. For mining equipment, we use a wire-reinforced fabric. It holds its structural integrity through many heat cycles. It also creates a more rigid blanket keeping the lagging off the hot face, manifolds and turbo – creating an insulative air gap.
The hot face layer will comfortably withstand a continuous temperature of 750°C
Insulation
The middle insulating layer made from 96% silica fibres is a poor conductor of heat. We can add/ remove layers depending on the engine.
We can achieve your desired surface temperatures to keep them below fluid ignition points and prevent burns.
Our wire-reinforced inner layer will withstand the vibrations of the idling engine. This keeps the insulation fibres contained and stops the blankets breaking down meaning they won’t require replacement as often.
Cold Face
The outer fabric layer is coated on both sides with silicone. Even if the outside suffers wear, there is a second line of defence against fluids. You can’t see it but the hot face layer is also coated with silicone on the inside.
This layer repels flammable fluids and directs them away from the hot parts of the engine. Without this, the oil can become absorbed into the blanket becoming a potential fire hazard.

Benefits of Exhaust Thermal Insulation Blankets
Using our MineBase Exhaust Thermal Insulation Blankets on your mining equipment has many important benefits. Being persistent with quality gives our customers the peace of mind they have selected the safest product for protecting their assets and their people.
Case Study
We have worked closely with a Mine Site in NSW that had issues with fires underground due to exhaust insulation not being sufficient for their needs. This particular site was reporting more than 4 incidents per year in the beginning.
Since MineBase has been involved there have been no reportable incidents directly relating to fires started underground from Lagging not being to standard.
MineBase continues to do quarterly auditing and maintenance on all insulation products and continuous QA measures are put in place to ensure the standard has been kept to a maximum.
Product Testing
We are continually testing our products with cutting-edge technology in thermal imaging and temperature testing.
Heat Testing
We regularly test new and different products and materials in the marketplace to ensure we are providing the best possible solution. The black MineBase Exhaust Thermal Insulation Blankets have proven to reduce the external temperature by 24% on average (Photo 1 below). The silver material with an inner and outer layer of mesh fared the worst as the mesh became a heat conductor over some time (Photo 2 below).
Oil Testing
We conducted an experiment on the repelling properties of different types of insulation which confirmed what we believed our unique safety edge to be. Photo 3 (below) shows the inner layer of an alternative blanket style has absorbed the oil and potentially could become a hazard. The MineBase Exhaust Thermal Insulation Blankets have repelled the oil. Photo 4 (below) also demonstrates the repelling properties of MineBase insulation.
Ceramic Coating & Exhaust Thermal Insulation
MineBase provides a proactive approach to exhaust thermal insulation inspections. This includes a comprehensive thermal image with temperature logging, alongside a still real-time photo to highlight any areas of potential threat or degradation.
This can be particularly misleading in infrared thermal imaging devices as the ceramic-coated surface will reflect the infrared beam from the testing device and therefore give a false reading. Download the Thermal Test Images here.
Frequently asked questions
Why do I need to install Thermal Insulation on my machine?
Not only does Thermal Insulation protect operators and fitters from exposure to high temps but it also reduces temperatures in high-risk areas, such as engine bays in close proximity to fuel and oil lines. Our Insulation has an outer layer that repels any flammable liquids from reaching ignition points. e.g. when a fuel/hydraulic line bursts and sprays onto a turbo or manifold which is particularly dangerous in an underground mine.
Do you install your Thermal Insulation Blankets?
Yes! We prefer to install as we are trained in this field and have the right tools for the job. This allows us to ensure there are no corners cut with our own in-house Q.A. process.
Can you supply Insulation for all types of machines?
Yes we can! We keep a very large library of designs on hand and have the capabilities of measuring all types of equipment to suit your needs.
What is your lead time?
Our average lead time from measurement to installation is 5 working days. Machines that we have already measured generally take 5 working days. This depends on the location, workload and machine components required.
How long will Lagging last on the machine?
It depends on what conditions or environment the machines are working in. e.g., underground mining where machines need to be washed down in constant sunlight etc. However, we have had machines in these particular conditions with Lagging still in perfect working order for over 4 years. Exhaust leaks will shorten lifespan.
Does Insulation over heat or damage turbos or other components?
No, our Insulation uses silica glass, which unlike fibreglass; when installed correctly by one of our trained technicians, keeps turbos and other exhaust components at an even temperature for more regular periods, which has been proven to increase their longevity.
