Technical FieldThe present invention relates to a novel multiple sandwich insulation system designed for superior thermal insulation and fire resistance in building constructions. Specifically, the invention introduces a sandwich element with integrated various insulation materials in a unique layered assembly, providing enhanced mechanical strength and improved fire protection characteristics.Background of the InventionTraditional insulation systems often face limitations in fire resistance and thermal efficiency. Existing solutions typically rely on single-material insulation, which may not provide the necessary balance of fire resistance, strength, and thermal insulation. The need for an advanced, high-performance insulation system that meets stringent fire protection standards while maintaining structural integrity has led to the development of the Next Generation Multiple Sandwich Insulation System.Summary of the InventionThe invention provides a sandwich insulation panel incorporating with an multilayered arrangement of materials to achieve superior fire protection, thermal insulation, and mechanical strength.The core innovation of this system lies in the unique combination and bonding of insulation materials into a unified, high-strength sandwich panel.Detailed Description of the InventionAs schematically illustrated in figure 1, the insulation system may comprise:1. Exterior Stone Wool Insulation (10): A 30mm thick stone wool insulation panel positioned on the outermost side of the wall sandwich panel, mechanically fastened with screws and washers for secure attachment.2. PIR Polyisocyanurate Insulation (11): A 40mm thick PIR insulation board with aluminum facings to enhance fire resistance, glued to the adjacent layer.3. Vacuum Insulation Panel (VIP) (12): A 15mm thick nano micro-porous fumed silica insulation panel, adhered to the calcium silicate plate for added fire protection and structural reinforcement.4. Calcium Silicate Plate (13): A 4mm thick high-strength fire-resistant plate bonded to the adjacent PIR insulation layer.5. PIR Polyisocyanurate Insulation (14): A second 40mm PIR insulation board with aluminum facings to enhance fire resistance, insulation is board positioned towards the interior, mirroring the properties of the exterior PIR insulation.6. Final Interior PIR Insulation (15): A 30mm thick PIR insulation board with aluminum facings to enhance fire resistance, insulation board is mechanically fastened with screws and washers to secure the complete system to structural studs (19).The core of the insulation system, identified as elements 11, 12, 13, and 14, is permanently bonded and pressed together to form a single solid sandwich panel with superior mechanical strength and fire resistance properties.• The total thickness of the central sandwich insulation element (11-12-13-14) is 100mm.• The overall wall system, including the exterior and interior insulation layers, totals 160mm, with a 1mm glue bonding coat ensuring structural integrity.• The system is adaptable to varying insulation thicknesses to comply with local building regulations while maintaining the same fundamental insulation structure.The combination of insulation materials results in a fire rating of EI 60, meaning the wall construction can withstand 60 minutes of fire exposure.Advantages of the Invention may comprise:• Superior Fire Resistance: The integration of stone wool, PIR, VIP, and calcium silicate enhances fire protection, achieving an EI 60 classification. • High Thermal Performance: The combination of PIR and VIP insulation ensures minimal thermal conductivity.• Structural Strength: Bonding the central insulation layers creates a robust and durable panel suitable for various construction applications.• Versatile Application: Compatible with wood, steel, or composite structural studs without compromising performance.• Adaptability: The system allows for thickness adjustments to meet different regulatory requirements while maintaining the same structural principles.The present invention provides the Next Generation Multiple Sandwich Insulation System represents a significant advancement in thermal insulation and fire safety for building applications. By combining multiple advanced insulation materials in a single unified panel, the invention provides superior protection against fire while enhancing mechanical strength and energy efficiency. The ability to integrate this system with various structural materials further increases its applicability in modern construction.
