Condensation between double-glazed panes

Mist or droplets sealed between panes usually indicate that the insulated glass unit’s edge seal has failed.

Likely causes

  • Age, movement or seal deterioration can let moisture enter the cavity between panes.

Safe checks you can make

  • Confirm the moisture cannot be wiped from either accessible surface and photograph how it changes.

When to stop and get urgent help

  • Treat cracked, loose or visibly moving glass as urgent and keep people clear.

How a glazing specialist can help

  • A glazing specialist can measure and replace the sealed unit; the whole frame may not need replacement.
