We all know that the quality of the insulation board pasting in the exterior wall insulation system is very important. The pasting of the insulation boards not only affects the insulation effect of the insulation system, but also is related to the life of the insulation system. Based on our long-term construction experience, we have summarized some key points to pay attention to in the construction of insulation boards.
