Thermal insulation double glazingThermal insulation properties are just one of the many advantages of double glazed windows and doors.

Double glazed window and door systems can keep homes up to 40% cooler in summer, 32% warmer in winter, and increase thermal resistance by up to 94%.

Most homes are installed with windows consisting of a single pane of clear glass measuring 3mm or 4mm in thickness. *In testing, based on an average house containing an 8% area of glazing in the entire building fabric (windows, walls, floor, and roof), as much as 87% of the heat gained during summer and 49% of the heat lost during winter can come from windows. Imagine the expense and carbon emissions that can be saved by reducing the energy that is needed to cool and heat homes!

Energy Efficiency with Thermal Insulation

Facts about thermal insulationDouble glazing has been known to increase thermal resistance by up to 94%, meaning less reliance on air conditioning units and heaters to maintain a level of comfort within your home. Together with the added benefit of reducing your energy costs, you are also contributing to a more sustainable environment. Plus, double glazing is supported by a host of environmental, technical, and economic credentials, making it a key part of cost effective thermal insulation for your home.

For the uPVC or thermally broken aluminium insulated frame, the second panel of glass and the air gap together achieve superior energy and thermal efficiency, keeping homes up to 40% cooler in summer. A great advantage for the hot Australian climate.

A window’s performance can be further enhanced by using Low Emissivity (Low-E) glass on the inner pane. Low-E glass coatings minimise the amount of ultraviolet and infra-red light that can pass through a glass panel without compromising the amount of light transmitted.
