Honeycomb Sheets for Noise Reduction and Privacy

"A highway in India installed honeycomb polycarbonate sheets as noise barriers. The multi-layered design reduces traffic noise by 20 dB, and the UV-stabilized surface resists fading in harsh sunlight. The durable structure withstands heavy winds, and the modular design allows for easy repairs. Effective and long-lasting."

Hans Schneider
Lightweight Honeycomb Sheets for Skylights and Atriums

"An airport in Germany chose honeycomb polycarbonate sheets for its atrium skylight. The lightweight design reduced structural load, and the honeycomb structure provided excellent insulation. The sheets’ high light transmittance creates a bright, welcoming space, and the fire-resistant rating met safety regulations. A perfect fit for large-scale projects."
