This is how a replacement double glazed window pane is made.
We use these to replace a broken, cracked or misted double glazed glass unit.
You can see the window being sealed, that is what will break down on a misted window and allow condensation to develop inside the panes.
We have a 5 year guarantee against our replacement double glazed window panes misting.
Our replacement panes are made in Birmingham West Midlands.
