What kind of insulation material is used in the construction of the north?
According to the functional requirements of Party A or plant to choose the type of roof sandwich panels, such as you want to set fire, then generally use rock wool; insulation, then with the composite board, as is the general insulation or important insulation (for cold storage) According to his weight. As for the upper and lower board general Party has a request, if the party did not ask hunger to see satin gripping and so on,
In other words, if the wall on both sides of the waterproof performance, it is necessary to use flexible waterproof casing; if only to consider the pipe through the wall, without considering the wall, the wall on both sides of the waterproof performance and displacement of the pipeline deformation You can use rigid waterproof casing Steel waterproof casing for the pipeline through the wall does not withstand the vibration and telescopic deformation of the structure (construction) buildings, suitable for pipe wall through the limited space or pipeline installation before the building (building) or the renewal of the pipeline For areas with seismic fortification requirements, such as the use of steel waterproof casing, should be in the pool wall or the external walls of the building on the pipeline near the flexible connection A type for steel pipe, B, C type for ductile iron pipe and cast iron pipe
At this point the insulation material should be deposited in the lower temperature side of the room to prevent moisture insulation. When the brick wall thickness of only 1/2 bricks, the higher temperature side, must lay the moisture-proof cement mortar surface layer. In addition, the installation of the refrigeration unit, according to product description. Attached: DD in the temperature of the ceiling cooling fan 1 . outside the balance expansion valve 1 .
