Triple glazed as standard
As part of Green Building Stores commitment to promoting ultra low
energy building design, we have switched our Ecoplus window production
to focus on triple glazing and since 1st June 09 have made
argon filled triple glazing more affordable by offering it at the same
price as double glazing for Ecoplus windows and doors. We believe triple glazing should become the
standard choice for windows and doors in the UK to help combat climate
change. Triple glazed windows are around 30% more efficient than double
glazing and can significantly improve the energy efficiency of homes,
saving money on energy bills and reducing CO2 emissions.
