High rise building exterior wall thermal insulation waterproof coat waterproof vapor permeable membrane city high rise buildings have sprung up and become more and more. With the continuous growth of building height, the requirements for building fire resistance, fire resistance performance and grade are constantly improving, and higher requirements are also put forward for building materials. Building materials that meet the fire protection requirements and have thermal insulation performance are gradually increasing, Rock wool board is a new type of fire prevention and thermal insulation material in cold regions. It is the fire prevention and thermal insulation clothing for high-rise buildings. The disadvantage of rock wool board is that it absorbs moisture to expand, and the expanded rock wool board will lose its thermal insulation performance. In order to ensure the rock wool

Interpretation of vapor barrier and isolation layer in building roof practice [Abstract] During the discussion on the optimization of building practice in the east area, there are different views on the choice of vapor barrier and isolation layer in roof practice. This paper will interpret these two items in combination with relevant atlas and other materials, and discuss with you, hoping to help the future work. [Key words] Vapor barrier film, vapor barrier isolation layer II. Vapor barrier film vapor barrier film is defined as the structural layer designed to reduce the air permeability of the ground, wall or roof in buildings; In roof construction, the vapor barrier is a structural layer designed to prevent indoor water vapor from penetrating into the insulation layer. In the cold

The setting of waterproof and breathable membrane of secondary waterproof material on metal roof American Canadian series 65/400 vertical locking aluminum magnesium manganese plate special plate type ensures the advantage of roof in waterproof performance. Its longitudinal length is without overlap, extending from the roof ridge to the gutter. In order to prevent the partial roof panel from losing its waterproof function due to the construction quality or some special circumstances, such as accidental damage of the roof panel, during the roof opening treatment, the project has set up a secondary waterproof layer, which means that the waterproof breathable membrane secondary waterproof layer is a flexible material, which is laid under the metal roof panel. The secondary waterproof layer of this project uses advanced waterproof and vapor permeable membrane materials

Definition of metal roof: metal roof generally refers to the roof enclosure system that uses profiled metal plates or metal sandwich plates to connect with the support system through fixed supports and fasteners, and transmit the roof load to the main structure through the support system, and the angle between the roof panel and the horizontal direction is less than 75 °. According to the principle of condensate generation, corresponding structural layers are set to prevent the air flow containing water vapor from moving between the structural layers of the roof system. In the above structural layers, the vapor barrier (vapor barrier film) and waterproof breathable film (waterproof vapor barrier) are extremely important structural layers. Definition of vapor barrier: vapor barrier (vapor barrier): prevent water vapor from entering the insulation layer

Solution I of Kedebang waterproof and breathable film in profiled steel sheet wall. Scheme 1 of profiled steel sheet wall. In areas with hot summer and cold winter (hot summer and warm winter), Kedebang thermal insulation reflective foil is set on the outside of the wall insulation layer, and Kedebang waterproof and vapor permeable film is set on the inside of the insulation layer to prevent rainwater from invading the wall structure. When indoor cooling is centralized in summer, Effectively prevent outdoor high-temperature and high-pressure water vapor from infiltrating into the structure to form condensation, and protect the thermal performance of the insulation layer. Kedebang thermal insulation reflective foil provides superior thermal insulation effect and effectively reduces building energy consumption. 2. In severe cold (cold) areas, the inner side of the wall insulation layer is provided with a Kedebang vapor barrier film. When indoor heating is conducted in winter

Cold storage is a low temperature building. During the operation of cold storage, there is always a temperature difference between inside and outside the cold storage. Therefore, water vapor is bound to migrate and diffuse from the high temperature side to the low temperature side. The general rule and trend in China, except for high latitude areas, is that the migration and diffusion of water vapor from the outside to the inside of the cold storage. The migration process of water vapor will inevitably lead to the decline of insulation performance of the insulation body due to moisture, Increase the energy consumption of the cold storage. If it is not handled well, it will also cause the structure and structure of the cold storage to frost heave due to the condensation of water, damage the strength of the structure and structure, and affect the service life of the cold storage. It is also because of this, the problem of moisture isolation of the cold storage is an extremely important problem in the construction and operation of the cold storage, and it must be emphasized to add

The waterproof air barrier film has good waterproof performance, can effectively block the invasion of wind and rain to the room, can effectively block the invasion of cold air, and has the effect of protecting the insulation layer to save energy. When used together with other thermal insulation materials (glass wool, rock wool), it can effectively prevent moisture from entering the thermal insulation layer, form an integrated protection for the thermal insulation layer, ensure the effectiveness of the thermal insulation layer, so as to achieve the role of continuous energy conservation and improve the durability of the building. The function of the vapor barrier membrane is vapor impermeable, waterproof, moisture-proof and other functions. The vapor barrier film is laid between the roof base course and the insulation layer, which can strengthen the air tightness and water tightness of the building, and slow down the
