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.
