These full-length aerodynamic side skirts streamline airflow along trailers and rigid vehicles by reducing turbulence and lowering drag. Their lightweight, durable construction provides continuous coverage along the vehicle body.
Government guidance recognises aerodynamic improvements as a practical measure to support fuel and CO2 reductions.
"Improving the aerodynamic performance of heavy goods vehicles (HGVs) has been identified as one of the measures that can be introduced to reduce a vehicle's fuel consumption and CO2 emissions."

Key Benefits
- Full-length coverage along both sides of the vehicle body.
- Lightweight construction to minimise added mass.
- Suitable for trailers and rigid-body applications.
- Improved airflow management that reduces aerodynamic drag.
Technical Considerations
When specifying full-length side skirts, consider the following:
- Material selection – GRP offer strength with minimal mass.
- Mounting and integration – secure attachment to the chassis and compatibility with underbody equipment.
- Serviceability – maintain access for routine inspections and maintenance.
- Regulatory context – ensure skirts do not affect required safety clearances.
Application Scope
- Long-haul trailers seeking improved fuel performance.
- Rigid vehicles aiming to enhance efficiency.
- Fleets supporting emissions or sustainability objectives.
How They Work
By enclosing the exposed side-wall area along the vehicle's length, aerodynamic skirts guide airflow smoothly and reduce underbody turbulence. This reduction in drag is most effective at sustained operating speeds and supports overall fuel-efficiency gains.
Frequently Asked Questions
What do full-length aerodynamic side skirts do?
They smooth airflow along the vehicle's sides to reduce turbulence and drag, supporting improved fuel efficiency.
Are these side skirts suitable for both trailers and rigid vehicles?
Yes. They are engineered for both applications and provide full-length side coverage.
Do aerodynamic side skirts add significant weight?
No. They are designed to be lightweight while still providing aerodynamic benefit.
