What is single glazing and when is it the right choice? Here's an honest look.
Double glazing means two panes of glass with a sealed gap between them. The trapped gap slows heat and sound transfer far better than a single pane can.
Single glazing is one pane of glass. It's simpler and cheaper, and on a sheltered, quiet opening it's often perfectly adequate.
