The space between the panes is usually filled with an inert gas like argon and sealed firmly around the edges with a main and secondary sealant. Inside the spacer bar lies a desiccant-- a drying representative developed to take in any residual moisture caught during production.

Over time, windows stop working due to a number of factors:

  • Thermal Stress: Constant expansion and contraction triggered by changing weather condition conditions weaken the seals.
  • Poor Installation: If a window is incorrectly fitted, the frame can put unequal pressure on the glass system, cracking the seal prematurely.
  • Aggressive Cleaning: Using severe chemicals or pressure washers around the edges of the seals can break them down faster.

  5. Installing the New IGU: A fresh, airtight double-glazed system is placed into the frame.
  6. Re-beading and Sealing: The beads are snapped or pinned back into location, locking the new glass firmly. The boundary is sealed to prevent water ingress.
