Exhaust Thermal Insulation Blankets
What are Thermal Insulation blankets?
Stop Engine Bay Fires Before They Start
Exhaust lagging, also called thermal insulation blankets, covers the hottest parts of a machine: manifolds, turbochargers, exhaust pipes and mufflers. Its main job is fire prevention. If a fuel, oil or hydraulic line fails, fluid sprayed onto an exposed exhaust can ignite almost instantly. Lagging keeps surface temperatures below the point where that happens.
It also reduces heat in the engine bay, protects nearby hoses, wiring and electronics, and lowers the risk of burns to operators and maintenance crews.
Non-absorbent by design. Oil-soaked lagging can become a fire hazard in its own right. Advance Global’s Lagging is non-absorbent, so leaked fuel and oil can’t soak into the blanket and become a fuel source.
Advance Global’s thermal insulation is the result of testing materials and methods from around the world. It balances heat resistance, low thermal conductivity, abrasion and vibration resistance, fluid repellency and incombustibility.
Exhaust Thermal Insulation Blankets are made up of 3 layers
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.
Since partnering with Advance Global, we have had no reportable fire incidents caused by non-compliant exhaust lagging.

Thermal Reporting
Lagging only protects your fleet if it’s still doing its job. Blankets get damaged, soaked or removed during maintenance, so we offer on-site thermal inspections that show you exactly where your hot surfaces are, before they become an ignition source.
We inspect each machine at operating temperature, capturing a thermal image and logged surface temperatures for every manifold, turbo and exhaust run. Each image is paired with a standard photo, and you receive a clear report for each machine that flags hot spots, degraded lagging and recommended fixes. We provide a comprehensive report detailing all this information.
Case Study
Advance partnered with an underground mine site in New South Wales that was recording more than four fire incidents a year, caused by exhaust insulation that wasn’t fit for purpose.
Audit. We inspected the site’s fleet to identify issues.
Engineer. We designed custom blankets for each machine model.
Supply. We manufactured and fitted the new lagging across the fleet.
Maintain. We carry out quarterly compliance audits.
The result: No reportable underground fire incidents caused by substandard lagging since Advance Global took over supply.
