With increasing environmental awareness, more emphasis is now being placed on ways to save energy in any building domestic or commercial. In recent years new regulations have been introduced specifying minimum requirements for energy efficiency. Glass can play an important role in this. Heat loss is normally measured by the thermal transmittance or U Value. The lower the U Value the greater the thermal insulation. Insulating glass units incorporating low emissivity glass into our upvc double glazing can significantly improve thermal insulation values.
