Energy Saving
According to a recent survey almost 40% of household energy is lost through windows and doors, therefore proper selection of windows and glass will enormously cut down this energy loss.
As can be seen from the U-Values in the graph, our PVC windows perform 2.5 times better in energy saving than standard aluminium frames, they also outperform wooden frames.
*Data based on WERS ratings for Awning Windows, all with standard 4mm clear glass (low e glass and tilt & turn windows will achieve even better results)

U-VALUE AND SHGC EXPLAINED

Windows and doors connect our internal living spaces with the outdoors. With this they can potentially lead to unwanted heat gain in summers and cause substantial heat loss during winters. As the awareness around energy efficiency is increasing, new homes and renovation projects are required to meet with given energy rating or star value. In order to achieve this rating, our uPVC windows and doors need to comply with the laid down performance values for energy efficiency. The terminology that we use to describe these performance values is known as U-value and Solar Hear Gain Co-efficient (SHGC).
U - Value:
The U-value measures how well a product prevents heat conducting through the whole window (frame and glass). It does not factor in solar heat from direct sunlight. A lower U-value is considered better.
SHGC:
SHGC is a measure of how freely solar heat passes through a window or door. The lower the number the less solar heat it transmits. Windows that have a high SHGC, allow a greater amount of solar radiation to be transmitted, absorbed and eventually released inside the house. This essentially translates that such glass units cause your home or building to heat up quicker. SHGC is expressed as a number between 0 and 1
