When the system works as planned, it traps air and prevents heat transfer. When the seal fails, outside moisture goes into the gap, and the insulating gas gets away, rendering the window far less effective.Indications Your Double Glazing Needs RepairFinding the early indication of window failure can conserve homeowners money on energy expenses and prevent more extensive structural damage.

Resealing and Re-gasketingRubber gaskets shrink and crack over time, allowing drafts and wetness. Professionals can strip out the old, brittle gaskets and insert fresh rubber seals around the sash and frame, dramatically enhancing thermal performance.4. Frame Realignment (Toe and Heel)If a window drops and catches on the frame when closing, it generally requires to be "toe and heeled."
