Aerogel Heat Shielding Improves Bus Passenger Comfort With Less Volume

High-performance thermal barrier insulation is 22 mm thinner

CHALLENGES

Insulation shielding of bus turbo engine compartment.
The insulation was needed to reduce the temperature inside the rear of the bus and improve passenger comfort.
Heat from engine elements, especially the turbo, was as high as 140°C (284°F).
With engine compartments becoming increasingly compact, high-performance insulation with limited volume was required.
The insulation solution had to resist diesel oil spills and high-pressure water cleaning.
The insulation performance could not degrade over time.

AEROGEL SOLUTION

Carpenter designed a solution of Spaceloft™ 6250 encapsulated between two metalized polyester foils.
Total thickness was 8 mm, compared to 30 mm of previous insulation.

BENEFITS

Aerogel solution delivered required thermal performance while dramatically reducing insulation thickness by 22 mm.
Encapsulated pieces were easily installed with rivets in high-temperature zones of engine compartment.
