Windows are rated for energy efficiency in much the same way as household appliances and have a ‘rainbow’ label showing the efficiency of the window and all of its parts.
The scale ranges from the least efficient – E rating – to the most efficient – A++ rating, Spartan offer a wide range of windows with energy ratings from B to A++.
The better the energy efficiency rating the less heat you’ll lose through your windows and the lower your heating bills will be.
