Much emphasis is placed on ceiling and wall insulation while heat transfer through windows is ignored.
The use of standard clear glass creates a weak point in the building envelope, often referred to as the thermal wound in a building envelope, due to the easy transfer of heat through the pane.
Energy efficient glass (mainly insulated glass units) has been used in many countries world wide for many years. It has proven to be the only real solution to the window insulation problem.
Utilising energy efficient glass will give many benefits to a building. The comfort levels of the building will be superior to standard glass; it will be significantly warmer in winter and cooler in summer, allowing for less artificial temperature control.
An energy efficient building reduces the amount of greenhouse gases produced, contributing to the health of the environment for future generations.
The use of energy efficient glass products enables the design of buildings to have large areas of glass. There is nothing more appealing than a home or commercial building that has a large amount of natural light. Large window areas create a feeling of space and being one with the outdoors. This can be done without sacrificing the energy efficiency of the building, with the correct use of glass.
With the right combination of Insulated Glass Units, there is a solution for all applications. Insulation, solar heat gain reduction and solar heat gain can be achieved.
