In regions like the Swiss Alps, hopper windows are essential for basement ventilation while maintaining high thermal resistance against extreme snow and sub-zero temperatures. Our systems meet the rigorous demands of altitude-specific weather patterns.
Cities like Zurich and Geneva are seeing a surge in "Smart Building" renovations. Our AI-integrated hopper windows provide automated ventilation cycles, syncing with HVAC systems to reduce the carbon footprint of heritage and modern structures alike.
Energy efficiency is non-negotiable in Switzerland. Our factory produces triple-glazed hopper solutions that align with Swiss Minergie-P standards, ensuring U-values as low as 0.8 W/m²K for sustainable living.
