At Glasstech Galway we supply and install a wide range of glass products, processed glass, safety glass, Low-E Heat retaining Double and triple glazing.

It may surprise you to learn that up to 25% of the heat in your home can be lost through your windows. Without energy-efficient glazing, you are effectively throwing your money out of the window.

Did you know that by installing low-e Double glazing glass, you can significantly improve your window energy ratings and reduce the amount of energy lost through your windows by up to 75%! 

Considering these figures and the cost of fuel today, it is easy to see why more and more people are opting for A-rated by incorporating low-e glass into their existing window frames.

The rate at which glass transmits heat out of the building is measured by the U value.  The units for the U value are W/m2K (Watts per square metre per Kelvin temperature difference). The larger the figure, the greater the heat loss. 

If you have a house that has 20m2 of glass and its U value is 5.8 (single glazing) and it is 10 degrees colder outside than inside then you will be losing 1160 Watts (=5.8 X 20 X 10). This is a rate of loss greater than one bar on an electric fire. 

By replacing the glass with a low-e product the U value might become 1.5 so you are now only losing 300 Watts (almost a quarter of the heat loss).  Improved window seals and draft proofing will also improve the overall insulation properties of the window saving even more energy.
