Yes. Whatever frame you choose for your windows, simply by having a Saveheat energy-efficient glazing system, you will be making a positive step towards reducing your carbon footprint. A Saveheat energy-efficient glazing system will make the most of the heat from the sun - the low emissivity of the glass means the absorbed solar heat is reflected back into your room. In conjunction with this, a Saveheat system will also prevent heat escaping from your home - keeping it warmer when you need it to. You'll use less energy/fuel to heat your home, in turn, reducing your carbon footprint.
