Vacuum Insulated Glazing (VIG) is a new product to most people but is becoming increasingly popular. Its similar to a double glazed sealed unit, two pieces of glass put together but instead of it being gas or air filled vacuum glazing has the air suctioned out. In Comparison to Double & Triple glazing its performance out weights both. VIG’s thermal transmittance also known as the U-Value is 0.40 W/m2K comparing it to a double glazed unit which is 1.5 W/m2K or even an A Rated unit which is 1.1 W/m2K. Triple glazed being 0.8 – 1.0 W/m2K.
This makes Vacuum Glazing perfect for new buildings as windows are a significate contributor to energy efficiency. Windows in listed buildings were primarily glazed with single 4mm glass which gives a U-value 5.8 W/m2K. Due to restrictions you have to preserve the character of the building which means that it might prevent you from upgrading. This is where VIG not only super efficient but is also very practical for older traditional building. All that is needed is to replace/ change the glass. This would lower those expensive energy costs and gain you a warmer home whilst preserving the character of your building. Another strong advantage is Vacuum Glazing comes tempered (Safety glass) as a standard which reduces the risks of injury if broken dramatically compared to the standard 4mm single glass.
