UPVC Extreme Windows

Our UPVC Extreme Window is far from your standard or ordinary UPVC window design.

“Extreme” is the most fitting word to describe the industry-leading UPVC windows offered by TWC. They deliver extreme performance in every respect, particularly when it comes to thermal efficiency and security, and they can even outperform standard A-rated windows, considered by many to be the best window option on the market. Huge breakthroughs have been made by our engineers and designers to ensure the extreme range expertly retains internal warmth and subsequently reduces the resilience householders have on their heating systems. Extreme UPVC windows are also intelligent enough to draw in the heat of the sun almost like some kind of magnetic force. Join the growing number of Wiltshire homeowners opting for extreme window quality.


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. TWC 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.
