Glass & glazing replacement units and repairs….

What are the benefits of having Double Glazed Units?

  • Heat loss through single glazing will be at least halved with double glazed units
  • Draughts through windows caused by sinking cooled air will be less with double glazed units.
  • Rooms will be warmer with double glazed units.
  • Outside noise can be reduced with double glazed units.
  • Condensation can be reduced with double glazed units.
  • Savings on fuel bills with double glazed units.


Glazing Options:


Safety Glass – This can be either Toughened or Laminated .

Safety glazing is mandatory for new installations within 800mm of the floor in windows and partitions, and within 1500mm of the floor in doors and side panels. Glazing is marked in the corner with BS6206.

Low Emissivity glass or Low E glass- The glass must be used in a double glazed window so that the special reflective coating, which is always placed inside the cavity, is protected from any damage.

Argon Gas filled units are used to improve the thermal and in some cases the acoustic properties of the double glazed unit.

Low-E Energy Saving Glass can only be used for glazing as part of a Double Glazed Unit.

Low E Energy Saving Glass is designed to help insulate your home by keeping as much heat inside as possible. The glass has a transparent metallic coating on one side that reflects heat back into the room rather than allowing it to escape through the window. It also allows optimum amounts of sunlight to pass through the window.


There are two choices of Low E Energy Saving Glass, these are called Hard Coat and Soft Coat.  They both perform the same job but the soft coat has better thermal insulation, therefore reducing heat loss even further. The inner surface of the glass stays warmer thereby reducing the likelihood of condensation. And there is less of a yellowish tint or dusty appearance to the glass.

Energy Facts: Around 20% of the heat lost from homes is lost through the windows. Each home produces about 6 tonnes of CO2 per year. The average home could save 2 tonnes of CO2 per year. Turning your thermostat down by 1degree C could reduce your heating bills by 10%.
