With the rise of energy costs on everyone’s mind, more and more homeowners are looking for ways to reduce their energy consumption.

Energy efficient window

While there are several benefits of uPVC windows, their energy efficiency makes them the number one choice for an energy saving window frame material.

So why is uPVC so efficient?

Double glazing

This is a mechanism which involves two strong panes of glass joined together at the frame but separated by a small vacuum. The gap between the glass is sealed and filled with argon gas, meaning no air can escape.

This gap acts as a thermal barrier, allowing heat to radiate into your home. As such, you won’t need to rely on your heating as much, meaning you can reduce your energy bills.

Low U-values

U-values measure thermal transmittance – essentially, if the U-value of a window is low, this is an indicator of high thermal performance.

At Global Windows, our uPVC windows are manufactured using advanced technology to achieve low U-values and offer maximum thermal comfort to your home.

Thermally broken frames

Another reason why uPVC boasts energy efficiency is that it is integrated with fully enclosed chambers. The benefit of these multi-chamber uPVC profiles is that they do not allow the heat to escape the room and cold air to seep inside.

What types of windows can you get from Global Windows?

At Global Windows, all our uPVC window styles are A-rated for energy efficiency, meaning you’ll benefit from a warmer, more comfortable home, while lowering your carbon footprint.

  • Casement windows – These use the latest technology to improve thermal efficiency and reduce heat loss.
  • Sliding sash windows – These windows can be enhanced from A-rated to A+ rated energy ratings if required, and are designed to help your home retain as much heat as possible.
  • Tilt & turn windows – These windows have excellent insulating capacities and will keep your home warm while saving you money on energy bills.
  • Flush sash windows – These windows are A-rated for energy efficiency, meaning you’ll have a warmer home in no time.
  • Residence Collection Windows – Available in R7 and R9 options, these windows achieve ‘A’ ratings with 28mm double glazing or ‘A++’ ratings with 44mm triple glazing, helping you create a warmer home and save you money on reduced heating bills.

How can I increase the energy efficiency of my windows?

At Global Windows, you can choose from either double or triple glazing for your windows. Both options are sure to improve the quality of your home life, as you experience increased warmth and security.

Our double and triple glazing options are both designed and manufactured to ensure optimal performance.

  • Double glazing – All our windows come with double glazing as standard, helping them achieve a high energy rating.
  • Triple glazing – By adding a third pane of glass to your windows, you’ll achieve lower U-values, maximising your home’s thermal performance.

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?

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.
