When would a membrane wall with studs and a layer of refractory be used?

A membrane wall with studs and a layer of refractory is primarily used in environments where there is a need to withstand high temperatures and protect against corrosive and abrasive conditions. This type of construction is particularly valuable in industrial applications, such as power plants and refineries, where the walls are exposed to hot gases and potentially harmful chemical reactions.

The refractory layer serves as an insulator, protecting the underlying structure from extreme temperatures, while the membrane design helps in maintaining structural integrity under stress. This combination is critical in preventing degradation and extending the lifespan of the equipment, making it the ideal choice for very corrosive or abrasive areas.

Other contexts such as low-temperature operations would not necessitate the robust protection that a membrane wall and refractory layer offer, and soundproofing in residential buildings or standard residential hot water boilers typically do not involve the same level of thermal and chemical stress seen in more demanding industrial applications.
