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.

Whether you choose double glazing or triple glazing, you’re sure to experience a home that’s been made substantially better by a Global Windows installation. Why not browse our wide range of windows today?

Staying in line with industry initiative

As Building Regulations standards become increasingly strict, more new build properties are being built with triple glazed windows. Triple glazed windows will increase home security, improve your home’s energy efficiency rating, and save you money in the long term. When you upgrade your windows to triple glazing you create a comfortable home all year round.

Testimonials

Our customers' feedback is important to us. Read our latest customer testimonials below.

Three first floor windows across the front of our detached house

"The three windows were fitted to replace old, blown units. Mark (the fitter) was efficient, polite and skilled. The quality of the units and the workmanship was excellent and Mark cleaned up any mess he made, both inside and out. I was told by the surveyor that the old units would be recycled which is really good in the present climate. Recycle, Reuse, repurpose. There have been no issues since fitting but there is a comprehensive guarantee included, so we have peace of mind for years to come. Well done Global Windows, which I will also add are a local company!"

"Efficient and courteous and a job well done"

- Checkatrade Review, October 2021

New windows / doors. Removal of external tiles above downstairs bay window and install cladding.

"Quality service from Global from start to finish. After going through the design process and placing order I was given a start date and that was exactly when the installation started. Product exceeded expectations as did the fitters (Andy and Shaun) who were brilliant. We have an old house that has suffered from some movement over the years so it wasn't a starightforward install but they really paid attention to the detail and did an amazing job. Would recommend to anyone."

"Competitive price, no pressure at all unlike other companies. Kept fully up to date with courtesy calls and emails. Customer service is excellent. Window fitters Sean and Andy were fabulous. Clean, tidy and friendly but also worked their socks off. Had a little issue with the patio door but sorted this straight away and is now perfect. Would highly recommend. Very satisfied with all aspects from quote to finish."
