Keeping Heat Inside

It is important to ensure that you do not lose the heat from your home through your windows.  Energy efficient glass will enable you to reduce energy costs and make your home more comfortable.

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 Energy Advantage Glass™. 

What is low emissivity?  Emissivity measures how strongly a product emits or radiates absorbed heat. The lower the number, the more efficiently the glass reduces heat gain or heat loss, which means a lower U Value and better insulation.

For buildings that require passive heat gains, a low emissivity coating with clear glass allows direct solar radiation to pass through the glass and then traps it inside. 

Pilkington Energy Advantage Glass™ reduces energy use and turns your windows into a source of free energy by combining high passive solar gain in the winter with excellent thermal performance all year round, to give your windows a real performance advantage over any other glass.
