Insulated Glass Description Insulated Glass is made of two or more pieces of glass with effective support and evenly spaced and sealed at the periphery to form a dry gas space between the glass interlayers. The interlayer of the insulated glass is initially dry air, and other gases with a lower thermal conductivity than air are currently used. The minimum thickness of the gas interlayer of the insulating glass should not be less than 6mm, otherwise it will not function as thermal insulation. However, the thickness should not be too large,if it is too large to make the insulated glass too thick. In order to standardize the production of the frame, the gaps of the insulated glass are currently divided into 6, 9, and 12, 14, and 16 mm. Any type of insulated glass consists of the following components: (1) The float glass constitute the insulated glass. These glasses can be ordinary laminated glass, solar control glass (including Low-E glass), and etc. (2) Gas interlayers and gases. In the interlayer of the insulated glass, firstly to ensure the performance of the insulated glass, the interlayer gas must be dry, including dry air, argon or other special gases. Generally, depending on the requirements, the thickness of the insulated glass interlayer and the internal gas are also different.
