insulated double glazing
Insulated double glazing represents a significant advancement in window technology, combining two panes of glass separated by a spacer and sealed to create an insulating barrier. This innovative system creates an air or gas-filled cavity between the glass panels, typically ranging from 12 to 16 millimeters in width. The spacing is precisely calculated to maximize thermal efficiency and sound insulation properties. Each pane is thoroughly cleaned and dried before assembly, ensuring no moisture or debris becomes trapped within the sealed unit. The edges are sealed with primary and secondary sealants, creating an airtight barrier that prevents moisture infiltration and gas leakage. Modern units often utilize low-emissivity (Low-E) coatings on one or both glass surfaces, which help to reflect heat back into the building during winter while reducing solar heat gain in summer. The cavity between the panes can be filled with inert gases such as argon or krypton, which provide superior insulation compared to regular air. This technology has become the standard for both residential and commercial buildings, offering a perfect balance of energy efficiency, comfort, and durability.
