Triple glazed windows consist of three sheets of glass. Each pane of glass is separated by a spacer bar, which creates an air gap or cavity. The air gaps or cavities provide the insulating layers that slow down the heat loss and reduce the opportunity for condensation to form. Air is a relativel

To put it simply, U-Value is the measure of the rate of heat loss through a material. Thus in all aspects of home design one should strive for the lowest U-Values possible because the lower the U-value – the less heat that is needlessly escaping. So for example single glazed windows have a

If you\'d like that extra bit of heat kept inside your house, then UPVC triple glazing could well be the solution for you. The extra pane of glass within triple glazing windows can keep in heat by as much as 20-30% or more in colder areas. And more warmth retained of course means less energy used
