How Does Double Glazing Work? The Science Explained
While the composition works well for breathing, it''s not ideal for slowing down heat transfer in double glazed windows. Heat travels slower in denser mediums.
Understanding the parts of a double glazed window can simplify both installation and maintenance. A clear visual representation helps to identify each component's role in ensuring insulation and energy efficiency. The window typically consists of two panes of glass, separated by a spacer bar that creates an insulating air gap.
The term double-pane glass refers to an Insulated Glass Unit (IGU) that consists of two layers of glass separated by a space filled with air or inert gas. The IGU is then fixed within the window sash and frame. Besides the gas, the two window glass panes are separated by a spacer.
Float glass has an inherently poor insulation property. Therefore, float glasses used in double glazed windows are coated to increase their energy efficiency. Tempered glass is made by heating glass at 700 degrees Celsius inside a special furnace. Once heated, it is cooled down rapidly.
Thermal insulation: You install double-glazed windows to prevent heat transfer through the glass. That way your HVAC system doesn't work as hard to maintain the climate in the house, and your energy bills go down. Sound insulation: A double-glazed window absorbs sounds from the outside and creates a quieter indoor space.
