| Abstract: |
A new type of translucent pre-fabricated structural cast glass modular assembly with high thermal performance, good light transmission and acoustic rating. The cast glass assembly is made from project specific 404mm wide low-iron U-channel cast glass. The inner and outer channels have different surface finishes – the former to act as a white board and the latter to facilitate auto-cleaning. Two U-channels are unitized into a ‘flange-to-flange’ arrangement and are bonded together with 2-part structural silicone in a bespoke polyamide extrusion. The cast glass assembly can span in excess of 4.2m without intermediate support or vertical mullions, and the overall thickness of the façade is only 144mm. The assembly represents an innovation in large unitized U-channel cast glass elements that have been fabricated and sealed off-site and installed on-site in modules of 4 channels wide generally, thus maintaining the quality of workmanship (especially the silicone) while facilitating a faster on- site installation than any previous U-channel cast glass façade. Windows with cast glass external louvres are also inserted into the system without additional structural elements. |
