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. NSG Group 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 Ug-value. 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 type of glass used in the insulating glass units in energy efficient windows is generally known as 'low emissivity' or low-e glass. Generally, the improvement over ordinary glass is made by applying a fine coating to the glass. The more well known and trusted low-e product is Pilkington K Glass™. Other products are available which have a better Ug value such as our own Pilkington Optitherm™.

When these products are incorporated in Pilkington Insulating Glass Units (IGUs) these are known as Pilkington Insulight™ Therm.
