vacuum insulated glazing
Vacuum insulated glazing represents a groundbreaking advancement in window technology, combining superior thermal insulation with slim profile design. This innovative glazing system consists of two glass panes separated by a vacuum-sealed space, typically maintained at pressures below 0.1 Pa, effectively eliminating heat transfer through gas conduction and convection. Tiny spacers, usually made of stainless steel or ceramic, maintain the separation between the panes while preserving the vacuum seal. The edges are hermetically sealed using specialized glass-to-metal bonding techniques, ensuring long-term performance and durability. The technology significantly reduces heat loss through windows, achieving U-values as low as 0.5 W/m²K, far superior to conventional double glazing. This advanced glazing solution finds applications in both new construction and renovation projects, particularly in historic buildings where maintaining original window frames is crucial. The system's slim profile, typically 6-8mm thick, allows it to fit into existing window frames while delivering modern thermal performance. In commercial buildings, vacuum insulated glazing helps achieve energy efficiency targets while maintaining aesthetic appeal. The technology also proves valuable in cold storage facilities and temperature-sensitive environments where maintaining consistent internal conditions is paramount.
