Is It Time For A Blown Double Glazing Repair?

Condensation can be a sign that your double glazing has blown. This happens when the seal between two panes has been broken which allows gases that are inert to escape.

Repairing your double-glazed windows is an absolute must. Not only will it save you money on your heating bill and cut down on outside noise but it also improves the insulating properties of the window.

Seals that are damaged

The window seals of double-glazed systems are responsible for forming an airtight barrier and watertight. This keeps the warmth in and cold out. If the seals are damaged they can cause a myriad of issues, including windows that are misty, drafts and loss of energy. If your windows are beginning to appear to be damaged to the seals then it's time for repair or replacement.

One of the first symptoms you will notice is condensation that forms between the glass panes. This occurs when the inert gases inside the sealed unit degrade which allows warm air to enter your home. The inert gas cannot be replaced after this happens.

Another common sign is the appearance of black mould on your windows or window frames. This indicates that the seals are damaged and moisture is entering the frame. This could cause the wood to become soft, warp and peel paint. Once the window is replaced any moisture in the frame will be eliminated and you can regain the original thermal efficiency.

If you do decide to have your windows replaced or repaired, you should also think about upgrading the double-glazing to A-rated energy efficient glass because this will further increase the efficiency of your heating and will reduce your energy bills.
