Combine style and function with a truly modern product

WarmCore composite windows are the latest window option available for British homeowners. Designed with market-leading technology and innovation, they are the ideal addition to modern homes.

They are based on two key principles: style and performance. This is made possible with the combination of a thermally insulated uPVC core and aluminium cladding. This composite design ensures that WarmCore composite windows are some of the highest performing on the market – and are capable of achieving impressive Window Energy Ratings (WERs).

The latest window designs

WarmCore composite windows are designed from the group up. This means that rather than develop existing products, the windows offer something completely new – and that something is 25% more thermal efficiency, combined with stunning good looks thanks to slim lines and more room for glass. Choosing a modern home improvement has never been so easy!

Boasting some of the lowest U-values available (the measure of the escape of heat), WarmCore composite windows can help to make your home a pleasant environment. You are likely to save on heating costs too, which is great news for anyone concerned about rising heat hosts and their carbon footprint.
