uPVC double glazed windows

uPVC double glazed windows have plastic frames that hold heat well and two panes of glass that block cold and noise. They’re one of the warmest and quietest window options you can choose.

A common sign

“Our windows are freezing in winter and we can hear every car that goes past.”
Old single glazed windows let out heat and let in noise. New double glazed windows with insulating frames help with both.

About uPVC double glazed windows

Warmer, quieter rooms.

Double glazing traps a layer of air or gas between two panes of glass, which slows heat moving through the window. uPVC frames don’t conduct heat the way old aluminium frames do, so the whole window stays warmer to the touch.

This is a full window replacement, not a retrofit. It’s a bigger job, but it fixes the frame and the glass together, and new windows tend to seal far better than old ones.

Ask this

Ask about the whole window, frame and glass, not just the number of panes. The frame and how well it’s sealed into the wall matter just as much.

Single glazing is where a great deal of your heating escapes. These trades retrofit the windows you already have, or replace them properly.

A second pane fitted inside the window you already have. Far cheaper than replacement, and it works on heritage frames.
