The Glass: Two panes, typically 4mm thick, supply a barrier against the elements. The Spacer Bar: This separates the glass panes and normally includes a desiccant (drying agent) to take in wetness. The Gas Fill: The area between the panes is frequently filled with an inert gas, such as argon or krypton, which improves thermal performance. The Seal: Primary and secondary seals hermetically bind the glass to the spacer bar, keeping the gas in and moisture out.
