Retrofitting made efficient — and cost-effective

Many existing noise barriers no longer meet today’s acoustic expectations. Replacing them entirely, however, often involves high material costs, logistical complexity, and long approval processes. With PIN, there is a smarter and significantly more economical alternative.

Installed directly on top of existing barriers, the PIN noise-spoiler upgrades acoustic performance without the need for demolition or structural changes—reducing both investment costs and project lead times.

Key advantages

  • Performance upgrade without demolition: Older barriers can be brought up to modern standards using existing infrastructure — avoiding the high costs and environmental impact of complete replacement.
  • Substantial cost savings: By eliminating the need for new foundations, heavy machinery, and reconstruction permits, PIN reduces total project costs by a considerable margin.
  • Higher acoustic efficiency: The PIN element increases barrier performance through aerodynamic deflection and integrated sound absorption, helping reduce noise in compliance with current standards.
  • Fast and non-invasive installation: Retrofitting with PIN is quick and efficient. In many cases, installations can be carried out during ongoing operations, with minimal disruption to traffic or public space.

Typical applications

  • Railway or highway barriers no longer meeting acoustic requirements
  • Sensitive areas near residential developments or schools
  • Zones with recurring noise complaints
  • Projects operating under time or budget constraints

A sustainable and economical solution

Rebuilding is expensive—in terms of money, materials, and time. Retrofitting with PIN offers a cost-conscious alternative that also reduces resource use, emissions, and waste. It’s an intelligent way to modernize public infrastructure with a lower environmental and financial footprint.
