Insulation Board for Container Houses

Commonly used insulation board materials for container houses mainly include rock wool boards, polyurethane foam boards, and polystyrene boards. Here is a detailed introduction:

Rock Wool Boards

Rock wool boards are made from natural ores such as basalt as the main raw materials. After being melted at high temperatures, they are formed into inorganic fibers through high-speed centrifugal equipment, and then processed into finished products with an appropriate amount of binder added and cured. They have good thermal insulation performance, with a low thermal conductivity coefficient, effectively blocking heat transfer, reducing heat exchange between the indoor and outdoor environments, and maintaining a stable indoor temperature. At the same time, rock wool boards also have excellent fire resistance, belonging to Class A non-combustible materials. In the event of a fire, they will not burn or produce toxic smoke, buying valuable time for personnel evacuation and firefighting and rescue operations. In addition, rock wool boards also have a certain sound-absorbing and noise-reducing function, reducing the impact of external noise on the indoor environment. In the residential container house companies in Hohhot, rock wool sandwich panels are often used for box assembly, with an 80 to 100 mm thick layer of rock wool filled in the middle as the main insulation layer, effectively improving the thermal insulation performance of the houses.

Polyurethane Foam Boards

Polyurethane foam boards are a type of insulation material made from polyurethane raw materials through a foaming reaction. They have the characteristics of low density and light weight, facilitating transportation and installation. Their thermal insulation performance is excellent, with a low thermal conductivity coefficient, effectively reducing heat loss. Polyurethane foam boards also have good waterproof performance, with a high closed-cell rate and low water absorption rate, preventing moisture penetration and protecting the house structure from moisture damage. In the design, construction, and installation of insulation boards for residential container movable houses and cold storages in Golmud, Xining, Qinghai, a unique polyurethane foaming integrated forming technology is adopted to create composite boards with many superior properties in terms of thermal insulation and sealing performance.

Polystyrene Boards

Polystyrene boards are rigid foam plastic boards manufactured by heating and mixing polystyrene resin with other raw and auxiliary materials and polymers, injecting a catalyst simultaneously, and then extruding and molding them. They have the advantages of good thermal insulation effect and relatively low price, and are also used in some container house projects with not particularly high thermal insulation requirements and limited budgets.
