High performing glass

Glass is one of the most important factors in a window. At Koffman we only use low E glass in our double and triple glazing units which are filled with argon for better insulation. Glass spacing is always min of 12mm and up to 18mm which gives better thermal insulation. We use Saint Gobain for our glass as they are world leaders in glass innovation. They have special glass for extra noise reduction, thermal insulation, glare reduction, tinted and more. uPVC windows always have glass dry-fitted from the inside providing higher security.

Glazing choices are a super important part of your project planning. You can choose options that reduce UV and provide better heat retention which will improve your home comfort.
