FW1-85 Series is our newly developed mechanical unitized curtain wall system, without silicon bonding which gives more assurance for longer lifetime guaranty and easier replacement of glass in the future. The profile sections are designed to meet the different degrees of segmentations of the glass panel by having selections of adaptors depending on the project requirements, and this creates flexibility in convenience with circular designed buildings and structures. The system is using EPDM rubber to resist hot temperature and weather variations. There are designated brackets attached to every unit for lifting during the installation process. We have designed a special hook that compliments the bracketing system on every slab.
