On fiberglass mesh consequences of improper use arise
In paste polystyrene board exterior insulation system, alkali-resistant fiberglass mesh is enhanced role play, its own quality and construction quality is good or bad, and durability is directly related to the durability of the entire system. However, some projects will mesh polystyrene board close paste, or exposure to wipe the surface layer mortar outside, so not conducive to enhancing the role of muddy mesh of the system, resulting in the surface layer of impact strength is not enough, and easy produce surface cracks.
Special parts windowsill, balcony, awning, cornice, fall-mouth, parapet, etc. are error-prone areas. Because these poor construction site, because of various approaches differ, adverse reactions occur more. Comparison of change in these areas over the mesh overlap enough, ends mishandling, or plastering mortar strict closure, causing water leakage, and even thermal bridges. In recent years, the country newly completed buildings, because the outer insulation construction handled properly in the window, fall-mouth, cornice, etc. create a situation where the wall leakage occurs more, and to carry out major plugging difficult, because not easy to find the leak.
