Glass Damage and Cracks

Accidents or external factors can lead to glass damage or cracks in double-glazed windows. Damaged glass is not only unsightly but can compromise the windows:

  • Structural integrity
  • Energy efficiency
  • Safety

Cracked or broken glass not only affects the window’s functionality but also poses a potential safety hazard.

In the case of minor damage, temporary fixes such as applying clear tape can prevent further harm until professional assistance is sought. However, always be very careful around broken glass, it can cause serious harm. For more extensive damage, contacting a professional glazier is crucial to ensure the proper replacement of the glass panes and the restoration of the window’s performance and safety.

Condensation Buildup between Glass Panes

One of the primary issues faced with double-glazed windows is the presence of condensation between the glass panes, creating an unsightly appearance and potentially obstructing the view. 

Condensation occurs when there is a temperature difference between the inside and outside of the window, causing moisture to accumulate.

To tackle condensation buildup, it’s important to identify the root cause. Generally, there are three reasons why you might get condensation between panes:

  • Poor ventilation
  • Faulty seals
  • Excess humidity inside the home

Proper ventilation is crucial, so ensure that vents are clear and air can circulate freely. Additionally, checking and maintaining the window seals can help prevent moisture infiltration. If the problem persists, it may be necessary to consult a professional for further assessment and repair.

Drafts and Air Leakage

Drafts and air leakage can compromise the energy efficiency of double glazed windows, leading to increased energy bills and reduced thermal comfort inside the home. 

Detecting drafts can be as simple as feeling a cold breeze near the window. One handy trick is to use a candle flame to check for flickering near the window edges.

To address this problem, weatherstripping is an effective solution. Applying weatherstrips around the window frames can seal any gaps and prevent air leakage. Similarly, caulking can be used to seal smaller gaps or cracks. 

Regular maintenance and inspection of the windows can also help identify and rectify any issues that might contribute to drafts.

Failed Window Seals

Over time, the seals around double glazed windows can deteriorate, resulting in reduced insulation and increased noise infiltration. Failed window seals may manifest as fogging or moisture between the glass panes.

If you notice signs of failed seals, it’s essential to address them promptly. Professional assistance may be required to repair or replace the seals effectively. Ignoring this issue can lead to decreased energy efficiency, compromised insulation, and increased noise transmission.

Window Hardware Malfunctions

Double glazed windows rely on various hardware components, such as: 

  • Hinges
  • Locks
  • Handles

All of which can experience malfunctions and affect the overall functionality and security of the windows. Sticky hinges, loose or broken handles, or faulty locks can pose a risk to both the window’s operation and home security.

Regular maintenance, including lubrication and adjustment of hardware components, is vital to ensure proper functionality. If hardware malfunctions persist, consider consulting a professional to assess and address the issue. In some cases, replacement of faulty hardware may be necessary to restore the window’s performance and security.
