Modern aluminum facade using the MC Wall system. In Brzesko, we have completed a glass facade spanning over 312 m² using the MC Wall system – a modern mullion-transom structure designed for commercial buildings. The system connects vertical mullions and horizontal transoms with stainless steel pins, ensuring high structural load-bearing capacity and façade durability even under heavy wind loads. Gray Stopsol reflective glass was used in combination with triple-glazed units. This glazing specification brings tangible benefits to commercial buildings: effective solar control significantly reduces air conditioning costs in the summer months, while the mirror effect on the exterior provides privacy and gives the building a modern, representative character. Tempered glass ensures user safety, and the reflective properties protect against overheating. The MC Wall facade is a proven solution for commercial and service facilities, combining functionality with aesthetics and operational efficiency.
