Extruded Polystyrene Insulation Quiets Vehicles and Absorbs Impact Forces

No one likes a noisy interior of an automobile. Even vehicles rated for off-road use suffer in review points when the interior is noisy. Consumers today like high-end sound systems and lots of advanced electronics. Many of which speak to them in their language. Hands-free phone usage in cars is also popular. To do that well it needs to be quiet in the passenger compartments of cars, trucks and vans. Using extruded polystyrene insulation helps with deadening sound. However, it also has an added benefit. It absorbs energy during an impact.

Many may not think that a plastic product could do much during a collision at highway speeds, but plastics have been used for some time to absorb impact energy. A sports car made back in the 1980s had a honeycomb design built into the parts of the body. The car’s shell is mostly fiberglass. That substance was not know to be particularly good in a crash. The honeycomb design underneath the cool looking exterior fiberglass shell of the car absorbs energy well. Hidden extruded polystyrene insulation can also take the hit helping to keep crash energy from being transferred into the driver and passengers of a motor vehicle.

Most things in car design are built to serve as many useful purposes as they can. You cannot keep adding layer after layer of components in vehicles to make vehicles useful, beautiful and safe. You have limited space, weight requirements and fuel economy to consider. Every component needs to be as useful as possible. The nice thing about extruded polystyrene insulation is that it can make a vehicle quieter and it is ready to absorb impact energy passively. Things such as airbags and seatbelts need to be activated or deployed to be useful. Airbags have sensors, and seatbelts need to be put on by people in the car. Electronics and moving parts can fail. People can forget or neglect to put on seatbelts. Passive crash protection is always ready.
