Jointing System for Insulated Panels

Product Specifications

Technical details and manufacturing context for Jointing System

Definition

The jointing system is a critical component within insulated panel assemblies, providing structural integrity, thermal continuity, and environmental sealing at the junctions between individual panels. It ensures the overall performance of the insulated envelope by preventing air and moisture infiltration while maintaining alignment and load transfer. This directory entry covers jointing systems used in fabricated metal product manufacturing, typically for insulated panels in building envelopes, cold storage, or industrial enclosures. The system comprises interlocking profiles, gaskets, and fasteners, often made from galvanized steel, aluminum alloy, or EPDM rubber. It accommodates panel thicknesses from 50 to 200 mm, with joint widths of 10–30 mm to allow for thermal expansion. Operating temperature ranges from -40°C to 85°C. Tensile strength is at least 20 kN/m per ISO 527, and compression set is ≤25% at 70°C for 24 hours per ISO 815. Water tightness meets EN 12865 with no leakage at test pressure ≥0.5 bar, and air permeability is ≤0.5 m³/(h·m) at 50 Pa pressure difference per EN 12114. Fire resistance class ranges from A2 to B1 per DIN 4102. Material grades for corrosion-resistant parts are 304–316 stainless steel per ASTM A240. Weight per meter of joint length is 2.5–4.0 kg/m, and installation tolerance is ±2 mm. These values are reference ranges; verify model-specific parameters with the legal manufacturer or supplier. The jointing system's design ensures a continuous, airtight, and watertight barrier while establishing a rigid mechanical connection, critical for the longevity and efficiency of insulated structures.

Working Principle

The system typically employs interlocking profiles, gaskets, and fasteners. Panels are aligned, and their integrated male/female joints are engaged. Fasteners are then applied to draw the joints tightly together, compressing the sealing gaskets to create a continuous, airtight, and watertight barrier while establishing a rigid mechanical connection. The interlocking profiles guide alignment and distribute loads, while gaskets accommodate minor irregularities and thermal movement. Proper installation requires correct torque on fasteners to achieve the specified compression set and seal integrity. The system's performance depends on the compatibility of materials and adherence to installation tolerances. Regular inspection of gaskets and fasteners is necessary to maintain sealing and structural performance over time.
