Common Problems with Double-Glazed Windows and How They Can Be Repaired

Posted on: 14 November 2017

Ensuring indoor comfort is a top priority for people when they are constructing a new home. The kind of home windows installed has a significant effect on the home's indoor comfort. Double-glazed windows are the perfect modern alternative to traditional single-glazed windows because they provide a double layer of protection from solar heat radiation. Single-glazed windows comprise a single pane of glass. Double-glazed windows, on the other hand, are made up of two panes of glass separated by an air-pocket (vacuum) layer, which acts as thermal insulation. In some cases, the vacuum is filled with either dehydrated air or argon (an inert gas) to help minimise heat transmission and prevent condensation problems.

To ensure your double-glazed windows continue to be an effective insulative barrier against unwanted heat transfer into the home, it is important to keep the windows in good working shape. Otherwise, you may have to contend with paying high energy bills resulting from overworking of your air conditioning unit.

Read on below to get acquainted with some common problems you may face with your double-glazed windows and what you can do to fix them:

Damaged sealing

Double-glazed windows are usually sealed to maintain an airtight seal between the two separate panes of glass. If the sealing becomes broken or deteriorated, you will be faced with condensation problems, which will cause your windows to look foggy. To fix the issue, you will need to remove your window panes from the window framing and carefully wipe off the condensation from the glass. Once the glass is sparkling again, you can install them again and apply new sealing. For air-filled window units, a fresh supply of air will need to be injected into the vacuum layer before resealing can be done.

Damaged panes

Cracked, broken or distorted double pane windows may become an ineffective thermal barrier for your home interiors. The most effective way to deal with the problem is to replace any damaged panes, as glass cannot work and look like new again once it is damaged. However, damaged panes must be replaced with the correct type of glass.

The best way to ensure you get energy-efficient service from your double-glazed windows is to perform prompt repairs when need arises. You can always ask a window repair specialist to do the above repairs for you. Professionally done repairs will go a long way towards minimising your energy costs, over time.
