Why choose Global Windows for double glazing in Sheffield?

Single glazed windows aren’t yet a thing of the past for absolutely everyone, but they definitely should be. When you upgrade your windows to two panes of glass as opposed to a single one, you’ll find that your home not only has improved thermal efficiency and security, but is also more acoustically sound! Double glazing utilises two panes of glass with a space between them for an inert gas like Krypton or Argon. All windows from Global Windows come with double glazing as standard, which helps them achieve their ‘A’ rating in energy efficiency.

Triple glazing builds upon everything established in double glazing. By adding a third pane of glass to a window, you’ll achieve lower U-values, which maximises your home’s thermal performance. Triple glazing also brings with it the power to eliminate condensation and cold spots, stop draughts, and they’ll also reduce the noise levels from outside significantly more.
