Is it better to use rock wool board or foam board for movable plank house?

Movable plank houses can be insulated with rock wool boards or foam boards, but rock wool boards have higher fire resistance and are safer to use.
Rock wool board is a thermal insulation board made by high-temperature melting processing of basalt, which is widely used in thermal insulation work outside walls, as well as household appliances with specific temperature requirements such as refrigerators and refrigerators. Foam board is a kind of polymer material formed by microporous structure, which can isolate heat preservation temperature and prevent water infiltration. If you want to build a prefabricated house, it is best to use rock wool board, because rock wool board has the following advantages.
Advantages of rock wool board
1. Complex production process
Rock wool board is an inorganic fiber board structure formed by high-temperature melting processing of extracted natural ores such as basalt, and then compression molding. The production process of rock wool board is complex, which endows it with powerful performance characteristics, longer service life than foam board, safe, green and pollution-free. Moreover, during the construction process, the quality is light and easy to install and transport, which is very convenient and will not affect the environment.
2. Better performance than foam board
(1) Rock wool board is a thermal insulation material with strong thermal insulation performance, and its thermal conductivity is extremely low. Even if there is a huge temperature difference between the external environment and the indoor environment, it can prevent heat from seeping outward, ensuring the indoor temperature and usage requirements.
(2) In addition to its pure thermal insulation performance, the most popular feature of rock wool board is its fire rating. With the continuous development of science and technology, rock wool board can maximally prevent the expansion and combustion of the fire. It has great incombustibility and can avoid economic damage caused by high-temperature combustion.
(3) The use of wall materials to reduce noise is also a very important standard. The manufacturing process of rock wool board is complex and has a special structure. The porous connection formed inside can prevent the diffusion and propagation of sound.
4) Rock wool board is a green, environmentally friendly, non polluting material that will not affect the surrounding environment or harm human health. A large number of chemical testing studies have proven that rock wool boards do not poison or grow bacteria over time.
3. Simple construction process
The construction process is simple, with low requirements for workers, reducing construction costs and labor costs.
Disadvantages of foam board
Although foam board has a strong waterproof performance, it can organize water penetration and has strong hydrophobicity in the process of work. However, its special structural raw materials have resulted in its low fire resistance. During the use process, it is likely to be affected by the external high-temperature environment, causing serious incidents such as fires, causing serious harm to the personal and economic safety of consumers.
