Windows are the weakest link (thermally speaking) in your house. An uninsulated window is brilliant at cooling down all the lovely warm air in your house.
To stop this you have to insulate them – a layer of still air is best. In this DIY project we insulate a timber sash window with window insulation film.
It is affordable, easy and really makes a difference.
