A standard double-glazed system (typically called an insulated glass system, or IGU) includes two panes of glass separated by a spacer bar. The space in between the panes is generally filled with an inert gas like argon and sealed tightly around the edges with a main and secondary sealant. Inside the spacer bar lies a desiccant– a drying agent created to absorb any residual moisture caught during production.

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

• Age and Wear: Sealants naturally degrade after 10 to 20 years.
• Thermal Stress: Constant growth and contraction brought on by changing weather deteriorate the seals.
• Poor Installation: If a window is incorrectly fitted, the frame can put irregular pressure on the glass unit, breaking the seal too soon.
• Aggressive Cleaning: Using harsh chemicals or pressure washers around the edges of the seals can break them down quicker.

When the seal stops working, ambient air enters the cavity. When the temperature changes, condensation types on the within of the glass panes. Since the moisture is trapped internally, wiping it with a squeegee or fabric is impossible.

3. Extracting the Old Unit: The failed, misted glass unit is lifted out of the frame.
4. Preparing the Frame: The refund (the recessed location where the glass sits) is cleaned up, and setting blocks are adapted to guarantee the new system sits level and bears weight correctly.
5. Setting Up the New IGU: A fresh, airtight double-glazed unit is positioned into the frame.
6. Re-beading and Sealing: The beads are snapped or pinned back into location, locking the new glass firmly. The border is sealed to prevent water ingress.
