![]() ![]() How does a door keep the outside elements from penetrating into the interior?.The higher the number, the more light is transmitted. It is an optical property that is expressed as a number between 0 and 1. Visible transmittance measures how much light comes in through a product. Low-E glass improves thermal efficiency while allowing visible light through. Depending on the type used low-e coatings can be used to prevent heat coming in through a window in hot climates and, in cold climates can reduce the amount of long wave heat energy that is lost from a warm interior to the outside. Glass is coated with a very thin, virtually clear material that acts to reduce the transmission of infra-red rays through the glass. Tinted glass will have an effect on the energy efficiency and also the amount of light that enters through a window. There are a number of colours that are generally available including grey, green, blue and bronze. ![]() This is glass that has been coloured during manufacture by the inclusion of oxides. Gas is a better insulator than air so it increases the thermal efficiency of the window. They provide greater thermal efficiency to a window.Īn inert gas, usually argon, is used between the panes of glass in an insulated glass unit instead of air. This term applies to two (double glazing), three (triple glazing) or more panes of glass that are separated and sealed by insulation at the edges. Lights are individual panes of glass within a window In Australia most muntins are not part of the structure of the window but are simply glued in place. You can download the AGWA Guide to Window and Door Terminology (PDF) that shows each of these and the parts that go into them.Ī muntin is used in colonial windows to divide glass into multiple panes in the sash. Windows and doors are made up of a frame, sash (windows) and panels (doors).
