Single Double Triple Silver Low-E Insulated Glass Double Glazing Insulating Glazed Units Hollow IGU DGU

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.

(3) Edge sealing system. There are two types of recognized insulated glass edge sealing systems: one is the traditional cold edge sealing system (slot aluminum), and the other is a warm edge sealing system (composite strip type) represented by American Swiggle strip. Since the traditional aluminum trough insulated glass products have been used internationally and domestically for a long time, they have been recognized by many people, and the warm-side system has been promoted in China in April 1997, and the products have not been widely recognized. However, since this product has been improved on the basis of the conventional method, the heat insulating and sound insulating properties of the insulating glass are greatly improved, and thus it has been accepted more and more popular.

The thermal insulation properties of the insulating glass are mainly its thermal insulation of the gas interlayer, so that the temperature difference between the two sides is close to or even exceeds 10 °C. This is because the gas in the interlayer is in a closed space, the gas does not convect, thus, convective heat transfer and conduction heat transfer account for only a small proportion of the energy transfer of the hollow glass
