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."

David Chen
Sustainable Honeycomb Sheets for Green Buildings

"A LEED-certified project in Chicago used recycled honeycomb polycarbonate sheets for wall cladding. The material’s thermal performance and recyclability contributed to energy efficiency and sustainability credits. The modern aesthetic and low maintenance made it a top choice for the design team. Innovative and eco-friendly."
