The area between the panes is typically filled with an inert gas like argon and sealed tightly around the edges with a primary and secondary sealant. Inside the spacer bar lies a desiccant-- a drying representative developed to absorb any residual moisture trapped during production.
Gradually, windows fail due to several elements:
- Age and Wear: Sealants naturally deteriorate after 10 to 20 years.
- Thermal Stress: Constant growth and contraction triggered by changing weather damage the seals.
- Poor Installation: If a window is improperly fitted, the frame can put irregular pressure on the glass unit, splitting the seal too soon.

- Setting Up the New IGU: A fresh, airtight double-glazed system is positioned into the frame.
