REXI insulating glass is a unit combined by two or more layers of glass and the space between them, around the glazing unit, we use high strength and airtight composite adhesive, then fill dry gas into the middle gap with desiccant to ensure that the air inside is dry enough.
Glass insulating can be divided according to the gas in the hollow cavity into ordinary (filled with air) and gasing (filled with argon, krypton and other inert gases). In China insulating glass factory, the thermal isolation function of the gasing one is better, and the tinted gas makes the color more changeable. Gasing insulating glass price is about 0.8-1 US dollars/square meter more expensive than the ordinary insulating ones.
In addition, the price is also related to the size of the unit. The smaller the unit size is, the more sealing and spacing materials are used per square meter. Therefore, the unit price per square meter is higher.
China insulating glass manufacturers make sure that the sealant should be uniform, continuous and neat, fully adhering to the glass, and does not exceed the edge, the spacer material should be smooth and clean, without any stains, spots or oxidation phenomenon.
Due to the change of environment and temperature, the gas in the hollow cavity is in a state of being expanded or contracted repeatedly, which makes the sealant stay under stress for a long time. The action of ultraviolet ray, water and moisture will accelerate the aging of sealant, so the water vapor in the environment will continue to penetrate from the insulating glass to the hollow cavity. At the same time, the desiccant in the sealing system is finally saturated due to the constant adsorption of water molecules, resulting in the water vapor content in the hollow cavity begins to increase. China's insulating glass suppliers determine the failure of product as there is visible the water vapor generated in the cavity.
