𝗔 𝗖𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱 𝗣𝗮𝘀𝘀𝗶𝘃𝗲 𝗛𝗼𝘂𝘀𝗲 𝗦𝘆𝘀𝘁𝗲𝗺: 𝗕𝘂𝗶𝗹𝘁 𝗳𝗼𝗿 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲
A few years ago, BGC Facades played a key role in the development and rollout of the Vizus AT135 hardwood/aluminium composite window system — 𝗮 𝗰𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱 𝗣𝗮𝘀𝘀𝗶𝘃𝗲 𝗛𝗼𝘂𝘀𝗲-𝗰𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝘁 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 designed for high-performance façades and energy-conscious construction.
AT135 is not just engineered to meet performance benchmarks — it is certified to support the most rigorous standards in low-energy design. With an inward-opening sash, triple thermal insulation glazing, and a highly effective thermal break, the system delivers exceptional U-values and airtightness in line with Passive House certification requirements.
𝗙𝗿𝗼𝗺 𝗮 𝗳𝗮ç𝗮𝗱𝗲 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗽𝗲𝗿𝘀𝗽𝗲𝗰𝘁𝗶𝘃𝗲, 𝗔𝗧𝟭𝟯𝟱 𝗼𝗳𝗳𝗲𝗿𝘀:
Certified Passive House performance credentials
Triple-glazed thermal insulation for outstanding energy efficiency
Resistance to air, water, and wind ingress under severe test conditions
Structural strength for precision in high-specification building envelopes
Aesthetic flexibility with timber-aluminium hybrid construction
What makes this particularly relevant now is that the 𝗨𝗻𝗶𝘃𝗲𝗿𝘀𝗶𝘁𝘆 𝗼𝗳 𝗖𝗮𝗺𝗯𝗿𝗶𝗱𝗴𝗲 has recently been reviewing systems of this calibre as part of broader efforts to reduce operational energy demand, evaluate embodied carbon, and deliver on long-term sustainability goals.
At a time when regulators, designers and developers are all under pressure to demonstrate compliance with new building performance frameworks, specifying systems like AT135 provides a certified, future-ready solution.
BGC Facades is proud to have helped bring this system to market — and continues to support B2B clients seeking technically robust, certified façade solutions for demanding projects.
