For hidden frame curtain wall, its glass panels are bonded to the metal framework using high-strength structural silicone. This is its featured structure. It is a seamless glass façade with only minimal silicone joints seen from outside, because the metal framework is completely concealed behind the glass panels. Such design creates a sleek, frameless appearance with a clean and pure aesthetic, free from unnecessary components.

To ensure outstanding performance in actual conditions, Sunframe’s hidden frame systems are certified to leading international standards, including AS4284 (façade testing for water and wind resistance), AAMA 2605 (high-performance coating durability), and ISO 9001 (quality management systems). These certifications guarantee reliable air tightness, water tightness, long-term durability, and compliance with global façade engineering standards.
