Energy efficient windows by Finlay

Windows are now manufactured and rated using a scale of A to G as seen on items such as washing machines and dishwashers.

Window Energy Ratings (WER)

This rating indicates the energy efficiency value of your window, with an 'A' rating being the highest you can get.

Energy efficient products result in less energy being lost, which in turn helps reduce the cost of heating bills and supports a reduction in carbon emissions.

Our range of windows is available in a certified 'A' rating that has been endorsed by the Energy Saving Trust.
