Where do you glue the doors and windows?

Among them, the internal and external sealing methods of glass installation are mainly gluing and sealing strip. Because of many factors such as gluing process standard and uncontrollable installation, the installation technology of glass assembly is changing from gluing to sealing strip in recent years.

How to choose glue for door and window installation?

01, low quality glue shall not be used.
In silicone sealants, the proportion of basic polymers in silicone is high. With the price of raw materials in silicone increasing year by year, the cost in silicone sealants is increasing.

In order to reduce the cost, some sealant manufacturers often use inferior raw materials such as white oil (poor aging resistance and insulating glass butyl adhesive solvent), silicone cracking material and high boiling material (many impurities, poor aging resistance and poor sealing performance) to reduce the cost. Once consumers use this inferior adhesive, the subsequent sealant is prone to premature aging and cracking, hollow glass tears, fog, rainbow, coating failure, and even glass plate falling off, which seriously affects the safety and service life of building doors and windows.

02, sealant selection suggestions

The national standard GB/T 8478-2020 for aluminum alloy doors and windows also puts forward requirements for sealing adhesive materials for aluminum alloy doors and windows. Corresponding product standards and test method standards have also been issued, including GB/T 14683 Silicone Building Sealant, JC/T 485 Elastic Sealant for Building Windows, JC/T 881 Sealant for Concrete Building Joints, etc.
