Energy Saving Window Features

The Frames:

There are a few of frame types for these new style windows. The first is the old favourite UPVC, this is really popular as they will last a very long time and have the capacity for recycling, which is good for the environment. The second is aluminium or even steel made frames, which are also good for recycling and also are really slim in their design, these also have a longevity. Next is the wooden frame which will have a lower environmental affect, but will also need to be maintained. The wooden frames are used quite often in rural areas or an area of conservation where the original framework was constructed from wood. The final example is the composite frame, this is made from a wooden inside framework that is covered by aluminium or even plastic which has little maintenance requirements and is also very weather resistant. London Glazing are experts on all features of new windows.

Energy:
The rule of thumb of most companies for the energy efficiency rating of their windows is to rate them according to a scheme that runs from the letter A to the letter G. This is a system like the one applied to some domestic appliances like refrigerators. These windows are assessed complete (glass and the frame) and rate the windows capacity to hold heat. This rating system is operated by a body called the British Fenestration Rating Council (BFRC). They have a website where you can find out more information. London Glaziers have all the knowledge and experience regarding energy efficiency.

Ventilation:
Sometimes the efficiency and heat retention of your new windows will actually work against you, as the tight fitting windows will reduce the ventilation and can cause condensation problems. There are windows available that are fitted with small vents built in that can help, so consider this before you buy your windows.
