Glass and energy consumption
|
Building heat loss means increased energy costs. Much energy wasted occurs in the form of heat escaping through window glazing. Major improvements in the thermal performance of glass have been made in the past three decades.

 To calculate building heat loss, the designer needs to know the U-value of different building elements. A low U value means a low loss of heat from the interior to the exterior of the building. In the last 30 years the glass industry has made enormous progress in the development of thermal resistance of glass. A better understanding of glass properties and this natural phenomenon has lead to a creation of special kinds of glasses, systems and coatings that minimise energy consumption and use alternative natural resources such as sun. Most utilise a low-e coating which is becoming the standard in insulating glass units. Other lesser-known systems include warm-edge spacers, double skin façades, electrochromic glass and technologies that have given a new meaning to energy conservation. By using these system you contribute to preserving the environment and reduce your financial costs. Check out the latest technologies used in the flat glass industry on the selected links.
