You can prevent or lower instances of insulated glass seal failure with a few good practices. For example, you can lower the possibility of seal failure by:

Having your windows installed professionally · Choosing a professional service that manufactures as well as installs · Inspecting your windows for issues, especially gaps between the window glass and the frame · Caulking gaps and seal any cracks you find outside around the window · Never using pressuring washing or heat guns on the windows Another good practice is to choose insulated windows that come with a long warranty. The longer the warranty, the better. This is important because the best method of dealing with glass seal failure is to call in your warranty.
