Keeping Heat Inside

It is important to ensure that you do not lose the heat from your home through your windows.  Efficient glass will enable you to reduce energy costs, make your home more comfortable and reduce the carbon emissions which will damage the Earth's atmosphere.  Pilkington have been at the forefront of development of glass products which enable this to be achieved. 

It is possible to assess how efficient a window is at stopping heat escaping by looking at its so called U-value. This is the measurement of air-to-air thermal conductance, or insulation between indoors and outdoors, through the glass.  The lower the number the better the insulation or thermal control.

However, this does not take into account heat coming in from the sun.  Solar energy will improve the overall benefit that the window will provide.  The recently introduced Energy Rating (ER), is a grading of the window on a similar energy efficiency scale as seen on domestic appliances.
