UPVC Extreme Windows

You have got to invest in UPVC EXTREME windows if home security is your biggest concern.

Our standard UPVC windows are impressive enough, but our UPVC EXTREME windows take things to a different level in terms of the security and energy efficiency they offer. After the installation of these EXTREME windows, your home couldn’t be more secure and as they exceed the thermal performance of standard A-rated windows, it will never have felt so warm. To ensure they justify their ‘EXTREME’ tag, we performed hours and hours of testing and they came through each assessment with flying colours. Take EXTREME measures and put your faith in these windows to deliver the very best all-round window performance.


Buying new window replacements shouldn’t be complicated...

It can be difficult for a first-time window buyer trying to figure out which of the many different window choices available they should invest in.

We believe it helps if you compile a list of reasons why you want new windows and how you want them to look and perform. This will help ensure you get new windows that satisfy all your expectations.

Please don’t feel like you’re on your own with your decision-making. ERG has a very experienced team of window specialists that will listen to your requirements and come with possible window solutions for the project. A short discussion with one of these friendly consultants will fill your mind full of inspirational ideas.

Use this checklist as a resource for buying new windows and you will be on the right track...

Aesthetics - Certain window styles suit a traditional cottage more than they would complement a modern property, and vice versa. Take into consideration the age of your house and its character before giving the green light to a window installation.

Thermal Efficiency - The annual average household energy bill continues to rise at an alarming rate and to bring those fuel costs down you need thermally efficient windows fitted. Take notice of the individual energy ratings of each window design you see as this will highlight the thermal performance of the product. You want something that keeps heat in, rather than letting it escape freely.

Motivation - Be clear in your mind about your motivations for replacing your existing windows. What are your current windows failing to do? Have they lost their looks? Are they ineffective at heating your home? You tell us the motivation/s and we will seek to come up with the resolution.

Finishing Touches - There are so different elements to a window aside from the window frame and glass. The hardware affixed to the design plays a massively important role in functionality and aesthetics. Our high-security hardware will also add further security to our windows.
