Prime standard windows are 'A' Energy Rated as standard helping you to reduce your carbon footprint! 
CO2 is the main greenhouse gas effecting climate change. Our homes cause a quarter of all CO2 emissions in the UK. Windows can account for 23% of the total heat loss (CO2) from a building. Energy Efficient Recommended windows are one of the most effective ways to save energy and reduce CO2 emissions. By choosing Prime windows, you’ll be cutting your CO2 emissions which will save money on fuel bills. 
Energy Efficient Ratings 
How do you tell if your windows are energy efficient? The British Fenestration Rating Council (BFRC) has introduced a window energy rating scheme very similar to that of domestic appliances. Products that have been tested will display the ratings grade A to G, A being the highest, G lowest. Those with C or above will be able to use the Energy Efficiency tag. 
Prime products are available to give you a choice of windows with ratings from A – C. 
Energy Efficient Guarantee 
Windows achieving a BFRC window energy rating of C or above can be endorsed under the Energy Saving Trust’s Energy Saving Recommendation scheme. This allows the use of their logo to assure customers that the window has met set criteria on energy efficiency. 
Six reasons to choose our Superspacer 
1. Reduce noise by up-to 2dB. 
Choices products have been proven to reduce noise transmission by up-to 2dB. 
2. Reduce Heat Loss by 94% 
Choices thermally efficient products are such that they can help reduce heat loss by a staggering 94% 
3. Block energy loss. 
Small things make a big difference. Aluminium spacers suck heat from inside to the outside causing energy loss through your windows. No-metal Super Spacer locks heat in saving energy and money. 
4. Reduce condensation by up-to 70% 
This virtually eliminates the potential breeding ground for mould growth and the bacteria that can be harmful to those who suffer from asthma. 
5. Be 950x less conductive 
Super Spacer no metal technology prevents thermal bridging. This is when warm air is sucked to the outerside of the window.  
6. Be Warmer at the edge. 
Choices windows have a warmer internal edge temperature of up-to 65% which reduces heat loss and energy. 
Less heat loss mean lower fuel bills for you. 
Fitting Energy Saving Recommended (ESR) PVC-U windows will raise the total energy efficiency of your home. 
Over 15% fuel savings on average. 
Less energy consumed results in lower carbon emissions, which is good news for the environment 
High performance – a standard E rated window can have up to 94% more energy loss than a C
