On-highway trucks, buses, and heavy-duty vehicles depend on managing exhaust heat to meet emissions standards, protect cabs and components, and deliver reliable service life. From turbocharged diesels to natural gas powerplants, the exhaust and aftertreatment systems running under a modern Class 8 truck operate above 1,000°F and sit inches from fuel tanks, air lines, and electronics.
On-Highway Insulation Applications
- Diesel engine exhaust manifolds and turbochargers
- DPF, DOC, and SCR aftertreatment systems
- Exhaust downpipes, mufflers, and tailpipes
- EGR coolers and exhaust manifolds
- APU exhaust on sleeper cabs
- Cab firewall and floor thermal protection
