Energy Efficiency

The energy efficiency of a building is an integral part of Building Regulations and PART L – the Conservation of Fuel and Power concerns itself with reducing the CO2 emissions. Windows and doors need to meet certain criteria in order to comply with this.
Changes in the regulations in October 2010 have meant that windows and doors need to be more energy efficient than ever before. There are two methods for proving compliance with building regulations – U Value performance or Window Energy Ratings (WERs).

Below shows the current minimum standards for compliance with Part L:

WINDOWS
U Value : 1.6 W/m2K
Window Energy Rating: C
Centre Pane U Value: 1.2 W/m2K*

"The workmanship of your fitters... superb work, on time, clean workers & very helpful"

"I was very pleased with the superb quality of my new windows. The workmanship of your fitters Paul & Dominic was excellent, superb work, on time, clean workers & very helpful"

With the rising cost of fuel, not to mention reducing your carbon footprint, the issue of energy efficiency is an important factor to consider when improving your property. All of the uPVC window systems manufactured by REHAU have very good thermal insulation properties which can significantly reduce heating bills. By retaining heat for longer within your property, heating times can be cut - reducing your carbon emissions by burning less fuel.

The measure for thermal insulation is given by the U-value of a window or door. The U-value measures the heat loss, hence the lower the U-value the better the thermal insulation.   find out more  >
