Failed Units

Failed double glazing units refer to situations where the sealed glass units in double-glazed windows or doors have lost their effectiveness or have developed issues. Double glazing units typically consist of two panes of glass with a sealed gap of air or inert gas in between, which provides insulation against heat loss, noise reduction, and improved energy efficiency. When these units fail, it can lead to several problems:

  1. Condensation: One of the most common signs of a failed double glazing unit is condensation between the glass panes. This occurs when the seal between the two panes of glass breaks, allowing moisture to enter. Condensation can obstruct the view through the window and reduce the insulating properties of the window.
  2. Reduced Insulation: Failed double glazing units lose their ability to provide effective insulation. This can result in increased heat loss during the winter and reduced energy efficiency, leading to higher heating bills.
  3. Drafts: When the seal around the double glazing unit fails, it can create drafts around the window or door, making the interior of the building less comfortable and causing temperature fluctuations.
  1. Noise Transmission: Double glazing units are also effective at reducing noise transmission from the outside. When they fail, the window may become less effective at soundproofing, allowing more noise to enter.
  2. Aesthetics: Condensation and cloudiness between the glass panes can affect the appearance of the window, making it less appealing and reducing the clarity of the view.

If you suspect that you have failed double glazing units, it’s advisable to contact a professional glazier or window specialist to assess the situation. They can determine whether the units can be repaired or if replacement is necessary. In most cases, when the seals are compromised or the glass is damaged, replacement is the best solution to restore the window’s performance and energy efficiency. Regular maintenance and inspection of double glazing units can help prolong their lifespan and prevent issues from occurring.
We can visit your property to inspect your windows and advise if you only require the glass units, our honesty will save you time and money. If you do require full unit replacement however, we replace units in uPVC, aluminium and timber frames.
