Worth knowing when you choose windows
Windows are sometimes rather poetically described as the house's eyes, but they also let in light and allow the interior to be aired. At the same time, they are expected to have the same ability to withstand the vagaries of the weather as the walls of which they are a part.
This requires a complex structure, where glazing, frame and sash work together. However, a quality combination is needed to meet the energy-rating criteria - and to give you the best return on an investment in new windows.
Always choose energy-rated windows
Replacing old and poorly insulated windows is always a step in the right direction. Replacing them with energy-rated windows is a massive step forward, both now and in the future. That's how big the difference is between an ordinary window and an energy-rated one.
