The difference between interior wall insulation materials and exterior wall insulation materials is that in the field of building insulation, interior wall insulation materials and exterior wall insulation materials each play different roles, have different characteristics and functions.

Interior wall insulation materials are mainly used for wall insulation inside buildings. Due to the relatively stable indoor environment, the insulation materials for interior walls mainly focus on their insulation performance and environmental friendliness. Common internal wall insulation materials include gypsum board, polystyrene foam board, etc. These materials have good thermal insulation effect and low thermal conductivity, which can effectively reduce the loss of indoor heat and improve the thermal insulation performance of buildings.

External wall insulation materials are mainly used for wall insulation outside buildings. Due to the changing external environment, exterior wall insulation materials need to have better durability, wind pressure resistance, and water resistance. Common external wall insulation materials include rock wool, glass wool, polyurethane, etc. These materials not only have good insulation performance, but also have high strength and durability, which can effectively resist the influence of the external environment and protect the stability of the building structure.

In summary, there are certain differences between interior wall insulation materials and exterior wall insulation materials in terms of insulation performance, environmental friendliness, durability, and wind pressure resistance. When choosing insulation materials, a reasonable selection should be made based on the specific usage environment and requirements to ensure the insulation effect and safety of the building.
