This indicates that the seal has broken down and it could affect your windows performance by allowing drafts in or out, and thereby increasing the energy costs. If a window is smudged, it must be replaced or repaired by an expert. This article will explain what needs to be accomplished and the options that are available. Repair The reality is that double glazing is a significant investment, so it's essential to maintain it properly. If you're seeing windows that are misting that mean the seal between the two panes is broken. This means your window is no longer sealed, and you'll lose solar gain, the energy generated by the heating system, and cold air. It's also likely that you will have an air draught in your windows and you could notice an increase in your energy bills since your heating system is working harder to keep your home warm. To avoid this, it's important to address the issue as quickly as you can. There are two options to the issue of double glazing misting. You can either fix the window or replace the glass panel. A professional will remove the moisture from the window and then apply new sealants in order to stop this from repeating itself. This usually involves drilling a hole in the frame and then inserting desiccant. The desiccant is able to absorb large amounts of moisture and will usually stop misting within a couple of weeks. When the issue is solved the sealants are changed and the hole is sealed. For older style double glazed windows, the issue may be due to the use of chemical cleaning products which can cause damage to the window seals over time. It is a good idea to have your windows cleaned by professionals who are FENSA regulated and follow the recommended procedures for maintaining your double glazed windows.
