What is the Best Wall Thickness for Prefabricated Houses?

The choice of wall thickness for prefabricated houses should be determined based on specific uses and structural requirements. Common thicknesses and their applicable scenarios are as follows:

75mm Wall: Primarily suitable for interior partition scenarios. In the interior space planning of a house, if different functional areas need to be divided, such as separating the living room from the dining room, a 75mm wall thickness is relatively appropriate. It can effectively divide the space while not occupying too much interior area, ensuring an open and transparent feel in the interior space, making each functional area relatively independent yet interconnected, enhancing living comfort and space utilization.

90mm Wall: Commonly used for exterior wall insulation. In house construction, the insulation performance of exterior walls is crucial as it directly affects the energy efficiency of the house. A 90mm wall thickness can provide a certain degree of heat insulation and insulation, reducing the transfer of heat between the interior and exterior, lowering the energy consumption of air conditioning and heating equipment, thereby saving energy costs and improving the energy efficiency and environmental friendliness of the house.

100mm Wall: Suitable for exterior wall insulation and light-duty house construction. For light-duty houses, in addition to ensuring insulation performance, certain structural requirements also need to be met. A 100mm wall thickness can better balance these two aspects, providing necessary insulation for the house while meeting the structural stability requirements of light-duty houses, ensuring the safety of the house during use.

120mm Wall: Mostly applied in heavy-duty industrial buildings. These types of buildings have high requirements for structural stability and load-bearing capacity, such as large factories and warehouses. A 120mm wall thickness can better meet the needs of heavy-duty industrial buildings, providing sufficient structural support to withstand large loads and pressures, ensuring the safety and stability of the building during long-term use.

In addition, walls prefabricated from Portland cement and steel studs generally have a thickness between 120mm and 150mm, suitable for brick-and-mortar buildings. However, these walls have drawbacks such as poor insulation performance, relatively weak load-bearing capacity, and stability, limiting their application in extremely cold or hot regions and areas prone to natural disasters. Load-bearing walls generally require a thickness of more than 240mm to provide sufficient structural support and ensure the overall stability of the building.
