Window Energy Ratings

By Plas-tech Windows

The Plas-tech range of windows bring light warmth and beauty into the home. If the windows are poorly selected they can become a major source of heat loss in the winter which increases the carbon footprint of the property and increases the heating costs.

The British Fenestration Rating Council Limited (BRFRC) window rating system has been developed to address this problem and allows you to compare the energy efficiency of different products.

All our window frames have been tested and comply with the BFRC Window Energy Ratings A to D when the correct double glazed unit is incorporated into the frame.


Energy efficient windows allow optional amounts of the suns energy to pass through the glass into the room allowing you to benefit from sloar heat gain. At the same time the advanced glass coating on the inside reflects the heat inside back into the room rather than allowing it to escape. Both these features reduce or eliminate the need for additonal heating.
