SIP Panel Prefabricated House
SIP panel prefabricated houses are a type of panel-type wooden structure house that uses SIP panels for prefabrication and on-site installation. They are characterized by simple construction and superior performance, and are widely used in various building types.

I. Structure and Materials
SIP panels typically consist of two outer panels and a layer of insulation core material. The outer panels are commonly made of OSB (Oriented Strand Board), but can also be replaced with magnesium oxide boards or cement fiber boards. The core material is primarily polyurethane (PU), but can also be EPS (Expanded Polystyrene) or rock wool for insulation. The structural principle is that the outer panels primarily bear the normal stress caused by bending deformation, while the core material provides sufficient sectional moment of inertia to bear shear stress. The two are bonded together with an epoxy resin adhesive layer to form an overall load-bearing structure. The panel thickness ranges from 4 inches to 12 inches (approximately 10.16 cm to 30.48 cm), with greater thickness providing stronger insulation performance, easily meeting the insulation standards for passive houses.
II. Application Scenarios
SIP panel prefabricated houses are suitable for single-family villas, multi-story apartments, low-rise commercial buildings, and public buildings. Their modular design allows for disassembly and reassembly, making them suitable for temporary or movable building needs, while also meeting the long-term use requirements of permanent residences.
III. Performance Advantages
- High Construction Efficiency: Prefabricated components are produced in factories, and only assembly is required on-site, shortening the construction period by more than 30% compared to traditional buildings.
- High Space Utilization: All pipelines are embedded within the walls or floors, with no protruding pipelines indoors, achieving a utilization rate of 85% to 90%.
- Energy Efficiency and Environmental Protection: They offer significant sound and thermal insulation, with energy consumption 20% to 30% lower than traditional buildings; the material recyclability rate exceeds 80%, meeting green building standards.
- Strong Earthquake Resistance: The overall structure resists earthquakes up to magnitude 8 through the coordinated load-bearing of the core material and panels, making it suitable for earthquake-prone areas.
IV. Design Flexibility
SIP panels can be customized in size and thickness according to building needs, supporting complex designs such as curved walls and high-ceiling spaces. Their lightweight nature (with a unit area weight only one-fifth that of concrete structures) also reduces foundation load requirements, expanding the range of building site options.
