double glazed white uPVC casement windows

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.

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.

    Thermal performance

    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.

    Frequently Asked Questions

    At Global Windows, we understand the importance of creating a comfortable and aesthetically pleasing environment for your home. We also understand that choosing the right home improvement is a big decision, which is why we’re happy to answer any questions you may have about our products and services.

    Can I retrofit my existing windows with double or triple glazing?

    Retrofitting existing windows with double or triple glazing is possible in some cases. However, it depends on the structural integrity of the existing window frames and the available space to accommodate the additional glass panes. We recommend you speak to a member of our team who will be able to assess the feasibility and suitability of retrofitting double or triple glazing to your existing windows. In some cases, it may be more practical and cost-effective to consider replacing the entire window unit.

    How do I know if my windows need replacing?

    There are several signs that can indicate that your windows may need replacing. These include increased energy bills due to poor thermal performance, difficulty opening and closing your windows, increased condensation, and excessive noise.

    Is it necessary to replace all windows at once, or can I do it gradually?

    It is not necessary to replace all windows at once. You can choose to replace windows gradually, focusing on the ones that need immediate attention or upgrading in stages based on your budget and priorities. However, keep in mind that replacing all windows at once can have advantages in terms of energy efficiency and consistency in appearance.

    Windows & Doors

    Brilliant company from all we’ve dealt with, right through to the fitters, to the follow-up emails making sure everything was ok. Having used you before and after having work done to my property, I thought you the only obvious choice to return. Was a little worried as I’d had insulated render fitted and was concerned about the removal and refitting into the same size opening, and the damage it would cause. No worries, it seems. Each to their own trade as they say, and I’m glad they managed it and left me in no doubt, another great job done. Many thanks to you all. And see you in 15 years again?

    Windows And Door

    After a fair few months of looking for a good window provider we can say we are one hundred percent happy with Global. They exceeded our expectations from start to finish. Michael with the quote, the lovely ladies from the office and Andy and Josh who fitted our seven windows and front door. Very professional, good quality, quick and efficient work. A pleasure to work with such a team. Our next step is the conservatory with Global. Thank you and well done to all.

    Excellent Service

    My mum wanted to say thank you so much for the fantastic service Global windows have given her following her burglary. From start to finish they reassured her the replacement patio doors would be robust and fitted as quickly as possible to ensure the property was secured. On the day of fitting the fitters arrived promptly and installed the doors with no mess. The gentleman who organised this from Global (sorry she couldn’t remember his name) came out to check the doors and to see mum was happy with them brought her a beautiful bunch of flowers. Mum was over the moon. Thank you so much.

    We decided to re-use this Company despite moving house and County. Global were helpful and very professional at all stages of the installation. We found all their staff friendly and knowledgeable. Dates given, returning phone calls etc. were all met. The price was very competitive, the quality of their products was excellent with a good range of colours and styles. The fitters were very hardworking, managed to get the work done in one day rather than the expected 2, mainly due to the fact they worked as a team, didn’t take breaks and clearly knew their job. Great company.
