Single or double glazing? Here's an honest comparison — including when single is genuinely enough.
For your home, we'd double-glaze the hot and noisy rooms and leave the sheltered ones single.
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.
We won't tell you to double-glaze the whole house. Double glazing earns its place on sun-hammered and road-facing openings; on a shaded, quiet rear window single glazing does the job. Spend it where it works.

Not always worth it — on a sheltered, quiet opening single glazing is often adequate. Double earns its place on hot or noisy elevations.
On sun-facing and road-facing openings, where heat and noise are actual problems.
