Thickness Requirements for Prefabricated Houses

The thickness requirements for prefabricated houses vary depending on specific components and application scenarios, with common specifications as follows:

I. Thickness of Prefabricated Wall Panels The thickness of prefabricated wall panels is primarily determined by functional requirements, with common specifications including 75mm, 90mm, 100mm, and 120mm.

• 75mm Wall Panels: Primarily used for interior partitions, meeting basic space separation needs while saving material costs. Suitable for non-load-bearing areas with low requirements for sound insulation and thermal insulation.
• 90mm Wall Panels: Commonly used for exterior wall insulation layers, enhancing thermal insulation performance by increasing thickness. Suitable for buildings in mild climates or with general energy consumption control requirements.
• 100mm Wall Panels: Balance exterior wall insulation and lightweight house construction needs, achieving a balance between thermal insulation performance and structural strength. Suitable for low-rise residential buildings or temporary structures.
• 120mm Wall Panels: Mainly applied in heavy industrial buildings or scenarios with high structural stability requirements, such as multi-story factories and warehousing facilities. Their thickness can bear greater loads and enhance impact resistance. In practical applications, the thickness of prefabricated house wall panels popular in rural areas of Henan is mostly 120mm, consistent with industrial building standards, reflecting an emphasis on durability and safety.

II. Thickness of Prefabricated Floor Panels The thickness of prefabricated floor panels is determined by material type, load-bearing requirements, and span, with common ranges as follows:

• Ordinary Cement Prefabricated Floor Panels: Typically 60mm-120mm thick, suitable for low-rise residential buildings or light-load scenarios, such as balconies and corridors, which are not primary load-bearing areas.
• Steel-Frame Lightweight Prefabricated Panels: Thickness ranges from 80mm-150mm, enhancing structural strength through built-in steel frames. Suitable for mid-rise buildings or spaces requiring larger spans, such as office areas in commercial buildings.
• Reinforced Truss Prefabricated Floor Panels: Thickness can reach 100mm-300mm, using high-strength reinforced trusses to enhance load-bearing capacity. Suitable for high-rise buildings, large-span factories, or scenarios requiring heavy equipment installation.

Design Principles: Floor panel thickness must be comprehensively calculated based on load, span, and material properties to ensure cost control while meeting functional requirements. For example, floor panels in residential bedrooms typically adopt a thickness of 100mm-120mm, while heavy-load areas like parking lots may require thicknesses exceeding 200mm.
