Microperforation for Noise Reduction & Air Permeability
Microperforation is a precise needling process that enhances the functionality of foils and technical materials. This technique serves two primary purposes: noise reduction through sound dispersion – Minimizes unwanted noise with targeted acoustic optimization and optimized air permeability – Improves ventilation and pressure equalization. Thanks to these enhanced material properties, microperforation unlocks new application possibilities across multiple industries. The process can be combined with various designs and is available as coil stock, custom-cut sheets, stamped parts, or 3D-formed components.
Industries & Applications:
✔ Automotive – Acoustic insulation for interiors, engine compartments & wheel arches
✔ Construction – Microperforated facades & soundproofing solutions for noise barriers
✔ Medical Technology – Sterile, breathable materials for filters & packaging systems
✔ Packaging Industry – Improved ventilation for sensitive products & protective packaging
✔ Furniture & Design Industry – Functional & aesthetic effects for high-quality surfaces
Our microperforated foils & materials are ideal for soundproofing, ventilation systems, thermal insulation, and functional design elements.
Innovation through microperforation – more than just holes
At Braun, microperforation is not just a technical process – it’s a strategic tool to enhance material properties, reduce resource usage, and boost product performance across industries.
We continuously explore new applications and technologies to push the boundaries of what’s possible with microperforation, including:
-
Thermal management in battery modules through targeted airflow control
-
Lightweight packaging solutions without compromising structural integrity
-
Moisture control in technical textiles and multilayer foils
-
Integration into smart materials for electronics, wearables, and sensor systems
From the earliest development stages, we consider sustainability and circular design. Microperforated materials can lower material consumption, improve recyclability, and contribute to eco-efficient product design.
Available designs:
- Smooth
- Calotte
- Large calotte
- Coarse grain
- Fine grain
