    Argon gas windows feature a sealed unit that is filled with gas between panes of glass to increase energy efficiency. This type of windows offer a lot of benefits: they minimize heat exchange through the window; reduce the possibility of condensation and frost; they can even block ultraviolet rays.


    IGUs can be sealed with Silicone or Polyurethane.
    Polyurethane is used for standard IGUs. Silicone is used for facades.


    The spacer bar is used around the edge of  the sealed unit design, in double glazed units it separates the two panes of glass by a preset margin. In FTCGLASS we use aluminium and plastic spacers.


    Warm Edge spacer bars are made of an insulating plastic composite material that becomes a barrier to heat loss. Warm edge spacers reduce the amount of heat lost through the sealed unit. They keep the edge of the sealed unit warm, hence the name ‘warm edge’. As a result less heat is lost through the windows and heating bills are lower.



    Energy-efficient glazing incorporates coated (low-emissivity) glass to prevent heat escaping through the windows. This makes the windows highly thermally insulating hence improving the energy efficiency of your home and helping to save money on your heating bills.


    Low-emissivity glass is a type of glass designed to prevent heat escaping through your windows to the cold outdoors. Low-e glass has an invisible coating which dramatically reduces heat transfer and reflects interior heat back into your room. Low-e glass is also recommended for north or east facing windows, where a larger proportion of heat loss would be expected.

  • Improves the energy efficiency of your home
  • Reduces your monthly bills
  • Decrease the size of your carbon footprint

    This is a new product, which keeps warm in the winter and cool in the summer, offering year-round comfort. It can be used for roofs and vertical glazing and is perfect for greenhouses.

  • Reduces the heat loss
  • Excellent solar protection
  • Reduces the heating and cooling cost and protects the environment
  • Good aesthetics, corresponding to the rest of the glazing
