Keep your home warm and your energy bills low! There are two frame options available, offering U-values as low as 0.9 (triple glazed) and 1.3 (double glazed)— the lower the U-value, the better the insulation. (For reference, a good U-value for glazing in the UK is typically 1.6 or lower).

Security
