How to identify the quality of insulating glass?

Method 1: Use a knife to cut the two sections of the two seals and the glass to a few centimeters, and then tear the sealant outward by hand. If the surface of the glass is smooth after tearing, there is no residual glue, indicating that the sealant and the glass surface have no adhesive force, so the sealing effect can be imagined.

Method 2: Investigate whether the standard molecular sieve is used, whether the butyl rubber is continuous (no broken wire), if it is not polysulfide rubber, whether the other two sealants have been tested for compatibility (must do the compatibility test, otherwise it is likely to be infinite ). If the window frame seal is not a standard rubber strip seal, but is sealed with ordinary silicone rubber, it is necessary to use the silicone rubber and the insulating glass edge sealant for compatibility experiments. Otherwise, it may endanger (some windows and doors are installed). The company purchased the inferior oil-filled silicone rubber to seal the window frame. Over time, the mineral oil migrated out to erode the entire insulating glass sealing system. Since it takes a while for this evil to manifest itself, it must be prevented in advance.
