As well as focusing on energy efficiency, my wife and I liked the modern look and wanted large triple glazing to make the most of the sea views as well as the garden, merging the indoor with the outdoor living space.

Mr Hamilton

Isle of Wight

It is always worth considering the external appearance of a house, which is quite often overlooked. A house has a roof, walls and windows and the windows make up a third of the property. Think about everything in detail.

Mr Humphreys


I am a really light sleeper and the windows have made a huge difference. I am now having the best sleep I have ever had in any house that I have lived in because it is so quiet!

Mrs Glassick


We liked the very high standard of construction, the rigidity of the frames and windows and particularly the ease with which these heavy sliding windows moved with the touch of a finger.
