The space in between the panes is usually filled with an inert gas like argon and sealed securely around the edges with a main and secondary sealant. Inside the spacer bar lies a desiccant-- a drying agent designed to take in any residual wetness caught during manufacturing.
With time, windows stop working due to numerous factors:
- Age and Wear: Sealants naturally break down after 10 to 20 years.
- Thermal Stress: Constant growth and contraction triggered by changing climate condition compromise the seals.
- Poor Installation: If a window is improperly fitted, the frame can put uneven pressure on the glass unit, cracking the seal too soon.
