Node design/usage
The joint width must meet the displacement capacity of the sealant. Normally, the joint width is controlled between 10mm and 35mm. The width to depth ratio of the joint should not be less than 2:1. Try to avoid applications with a glue depth greater than 15mm. The design of building joints must comply with relevant standards. The determination of joint size must comprehensively consider the performance of sealant, types of adjacent materials, joint working conditions, building type and size.
