Why choose double glazing?

Double glazed windows are significantly better than windows with just a single pane of glass. When your windows are double glazed, you’ll have improved thermal efficiency, better security, and they’ll also be more acoustically sound! This is all thanks to the inclusion of a second pane of glass, with space in between them for an inert gas like Krypton or Argon. All of our windows come with double glazing as standard, helping them achieve an A rating in energy efficiency.

Triple glazed windows

When you upgrade your windows from double to triple glazing you unlock a wealth of benefits. Improving upon everything established within double glazing by adding a third pane of glass, triple glazing will help you to achieve lower U-values which will maximise your home’s thermal performance. Triple glazing is guaranteed to eliminate condensation, stop draughts and cold spots, and significantly reduce outside noise.

Improving homeowner’s standards of living

When Global Windows install your new windows, your home will immediately feel more comfortable. New double glazed windows will vastly improve your home’s performance and create a pleasant living environment.

When you want your home to be optimised for security and energy efficiency, triple glazing is an excellent choice. If you live in a large urban area or near a busy road or airport, triple glazing could dramatically improve the ambience of your interior living space. With double or triple glazing, with Global Windows, every installation is a successful one.
