How double and triple glazing works

A single pane of glass offers very poor insulation, leading to a lot of heat lost through the glass in winter. Double – or triple – glazing traps air between two (or three) panes of glass, which by comparison to single glazing has twice the heat loss of double glazing.

Heat loss can be further reduced by coating one or more panes with transparent Low Emissivity (Low E) coating, which reflects the heat back into the room.

Thermally efficient window frames also help prevent heat loss and are ideally teamed with double or triple glazing. Other special glass treatments can be used in double or triple glazing for safety, security or fire resistance, or to match your decor.

Thermal performance

Thermal performance measures the effectiveness of glazing in reducing heat loss. This measure is called a U value and can provide a useful guide to the difference double or triple glazing could make in your home.

The higher the U value, the less energy efficient the window is, meaning more heat is lost. The U value of a single-glazed window can be 5 or higher, while a triple-glazed window could have a U value of less than 1.

This chart compares single glazing with double glazing (with and without a Low E coating) and shows just how effective these different forms of insulation can be.

Another useful measure of energy efficiency is our WEERS (Window Energy Efficiency Rating System) which rates the actual energy efficiency of the windows you purchase for your home.Glass and window

Why choose double or triple glazing?

JINAN SAINT BEST MACHINERY CO.,LTD is Professional MANUFACTURER&EXPORTER for kinds of glass machinery.We are one stop complete solutions for insulating glass,window&doors.

In double glazing, the air between the two panes of glass acts like an insulating ‘blanket’ – storing heat and releasing it slowly to help you control the temperature of your home. As the name suggests, triple glazing has three panes of glass, adding an extra insulating layer for additional warmth. It is most often used in colder climates, such as in the South Island.
