Background technique

At present, there are more and more projects using metal roof systems in the construction field, especially in some cities' landmark stadium buildings. However, in cold regions, due to the difference between indoor and outdoor temperature and vapor pressure in winter, air water molecules diffuse from indoor to outdoor, and finally form steam permeation and condensation on a certain structural level of the roof. During the construction process, holes left by improper roof puncture positions and gaps left by improper insulation layer will cause roof air leakage and condensation when the hot and humid air is cold, causing condensation, water leakage, and corrosion on the existing metal roof. It even affects the service life of the project, and there are many engineering cases with such problems. At the same time, during the construction and use of the existing roof insulation system, fires frequently occur and are difficult to control. Since the interior decoration and roofing materials are not flame-retardant, once a fire breaks out, the fire will be difficult to suppress and bring huge economic losses. The relevant supervisor Departments are also paying more and more attention to the fire performance requirements of thermal insulation materials.
