When problems develop, the immediate thought is typically about the incredible expense of complete replacement. Thankfully, property owners frequently have another option: fixing double glazing systems.
This comprehensive guide explores when to fix versus change, common issues, expense implications, and how to keep windows for optimum durability.
Understanding Double Glazing Units
Before diving into repair work, it assists to comprehend what a double glazing unit (often called an Insulated Glass Unit or IGU) really is. An IGU includes two (or often 3) panes of glass separated by a spacer bar around the edges. The gap in between the panes is filled with air or an insulating gas like argon, and a desiccant inside the spacer bar takes in any moisture.
