Panel Joint System for Insulated Wall Panels

Product Specifications

Technical details and manufacturing context for Panel Joint System

Definition

The Panel Joint System is a critical component within Insulated Wall Panels that provides the interface between individual panels. It ensures proper alignment, load transfer, weatherproofing, and thermal continuity across panel boundaries. This system typically includes interlocking mechanisms, gaskets, and fasteners that work together to create a seamless, energy-efficient building envelope while accommodating thermal expansion and structural movements. The system is designed for use in fabricated metal product manufacturing, specifically for insulated wall panels. It is a component-level product, meaning it is part of a larger assembly. The system's primary function is to join and seal panels, maintaining the integrity of the building envelope. It must accommodate panel thicknesses ranging from 50 to 200 mm, with joint widths of 10 to 30 mm to allow for thermal expansion. The load capacity is specified per linear meter of joint, ranging from 500 to 2000 kg/m, ensuring structural support. Thermal conductivity is low, between 0.02 and 0.04 W/(m·K), providing effective insulation. The system operates within a temperature range of -40 to 80°C, suitable for various climates. Sealing pressure is maintained at 0.5 to 1.5 MPa to ensure watertightness. Fabrication tolerance is ±0.5 mm, ensuring precise fit. Materials used include galvanized steel, aluminum, EPDM rubber, and polyurethane foam, with material grades for corrosion resistance specified as 304–316 stainless steel. The weight per meter of joint is 2 to 8 kg. Fire resistance classification ranges from A2 to B1 per DIN 4102. These parameters are reference ranges and must be verified for specific models and applications. The system is designed to maintain thermal and structural integrity, but actual performance depends on correct installation and adherence to specifications. Always consult the manufacturer for model-specific data and compliance with relevant standards.

Working Principle

The system operates through mechanical interlocking of panel edges combined with compression seals. When panels are joined, the interlocking profiles engage to provide structural connection, while elastomeric gaskets compress to create air and water barriers. Fasteners secure the connection while allowing for thermal movement. The design ensures continuous insulation across the joint while maintaining the panel's load-bearing capabilities.
