20 Fun Facts About Replacement Sealed Double Glazed Units
Benefits of Replacement Double Glazed Units

When the seals fail double-glazed windows and sealed units may be misted (or "blown") and result in heat loss and costly heating bills. Replacing the unit can create an airtight seal which can reduce condensation and draughts.
