How Does Bulletproof Glass Work?...New Building Regulations
Effective as of the 1st April 2002, a new set of building regulations (Document L) were established regarding the minimum level of insulation that all replacement windows fitted to your home must have. To achieve the required insulation values stipulated by the new regulations a low emissions glass, such as Pilkington K glass, must be used.
The glass in your windows absorbs heat from your home and then radiates out through the colder, outside surface. Low emissive glass has a microscopic, metallic oxide coating which can greatly reduce the thermal insulation of glazing. It allows short wave energy from the sun to pass into your room, just as normal glass does. However, the special coating reflects long wave radiation from internal heat sources, such as fires and radiators, back into the room rather than allowing it to escape to the outside.
As a result, up to 40% energy can be saved compared to standard double glazing. This means lower heating bills, as you can turn down thermostats by one or two degrees and still feel just as comfortable. It also brings the temperature of the glass closer to that of the room, thus reducing the likelihood of condensation forming on the internal face of windows. It also allows greater utilization of living areas through the reduction of cold spots and allows conservatories to be used for a larger part of the year.
