Benefits of Replacement Double Glazed Units Double-glazed windows (or sealed units) can be misted or 'blown' when the seals fail, leading to the loss of heat and expensive heating bills. Replacing the unit can restore an airtight seal that reduces condensation and draughts. The first step is to use a high-quality sealant that can endure thermal expansion and contraction. 1. Preparation Double glazing, or sealed units, as they are sometimes called, can improve your home's efficiency and make it safer. They do this by forming a sturdy barrier to intrusions.

This will remove any dust and debris that has accumulated within the frames over the years. Examine the frame for damage. Small damage can be repaired using wood filler and sanding. Major damage may need professional repair. It is important to measure the dimensions of the glass prior to when you put it in. If you are comfortable doing it yourself, you can use a straight edge with a ruler. Once you've gotten the measurements you can then begin to re-fit the glazing beads.

Failed or leaking double glazed windows allow heat to escape into the environment which causes your heating system to work harder to maintain the same temperature. A failed sealed unit can allow moisture to get into the gas that is used to insulate or the air-filled space between the glass panes, resulting in condensation.
