Energy Efficient Windows with Style: why compromise?


There’s no need to sacrifice style when choosing energy efficient replacement windows; a consideration even more important in a Conservation Area.


The installation of energy efficient windows means lower energy bills, a smaller carbon footprint and a more comfortable home; warmer, less draughty and quieter. Windows may be double or triple glazed, with a gap between the panes creating an insulating barrier. This gap may be filled with gases, such as argon, xenon or krypton to increase efficiency. Efficiency can be optimised with low emissivity (Low-E) glass to reduce heat loss and frames range from traditional wood to uPVC, with composite frames combining the two.


The efficiency of a window, frame and glass, is rated by the British Fenestration Rating Council (BFRC). The rating includes the u-value; the measure of how easily heat can pass through the material, with a higher u-value for higher heat loss. The u-value is only one aspect assessed in energy efficiency ratings.


Homeowners in Conservation Areas may be inclined to choose traditional wood to ensure compliance with strict design codes, despite wood’s inferior efficiency performance. The Residence9 range, available from Ilkley Windows and Conservatories, offers the perfect solution, with its authentic design features, from butt hinges to monkey tails handles, but with all the benefits of an A rated energy efficient window system.
