Turn Your Glass Into Radiators
Single glazed, timber sash and case windows are notoriously poor at retaining the heat in your home. The heat loss through single glazing is around 70%. This is because it has a high U-value (5.8 W/(m².K), meaning it is a poor insulator, the single pane is usually the same temperature as it is outdoors.
In the colder months of the year, as you heat your home, the warm air comes into contact with the cold single glazing and the air drops down, often mistaken for a draught through the joints of the window. This results in a constant convection in the room where the warm air is cooled by the single glazed window – and continual heat loss, which over time is hugely expensive.
Ultra slim FINEO glass has a low U-value of 0.7 W/(m².K), which is equivalent to triple glazing, and up to 8 times better than single glazing.
Retrofitting FINEO into your existing timber framed windows will transform them into invisible radiators by keeping heat in and cold out, no matter what the temperature is outside.
