Double glazing has been a standard for decades thanks to its durability, energy efficiency, and low maintenance. But even the best units don’t last forever. After 20–35 years, many double-glazed windows need to be replaced. Removing them isn’t as simple as pulling out the frame - the seals, putty, and gaskets holding the unit in place are tough by design. That’s where double glazing removal tools (also known as deglazing tools) come in.
Why Use a Deglazing Tool?
A deglazing tool is specifically designed to cut through stubborn sealant and glazing tape so the glass can be removed cleanly. Without the right tool, removing a window risks breaking the glass, damaging the frame, and creating a huge mess. A sharp, heat-treated blade slices neatly through gaskets and sealant, making the process quicker and far safer.
These tools aren’t limited to windows either. They’re equally useful on doors, bathrooms, and anywhere a watertight seal needs to be cut away, from sinks and baths to shower enclosures.
