However, this can be a short-term fix and a plug has to be inserted into the hole to keep it closed.

3. Locking Mechanisms

Double-glazed windows have gaps of air between the glass panes to keep out the elements and to help keep heat in the house. This type of window is also called an insulated glass unit (IGU). These windows can save money on heating costs by reducing energy consumption. They are not impervious to damage, and they may need repairs to double glazing.
