As modern architecture rapidly evolves toward intelligence and high-density development, the increasing precision of production equipment and the high added value of stored goods demand stricter fire safety performance from building envelope systems.
Traditional sandwich panel structures often struggle to meet the fire protection needs of sensitive environments such as precision electronics plants, high-value logistics centers, and public buildings due to issues like structural collapse under high temperatures or segmented core failure.
HXY-FD-W-SHEB Four-Joint Pure Rock Wool Metal Curtain Wall Panel is a newly developed product system based on HEADSTREAM’s four-joint curtain wall sandwich panel series. Its most distinctive feature is the use of pure rock wool core material, which has already been successfully applied in various high-end industrial building projects.
The four-joint design combined with pure rock wool core creates multi-level fire barriers in both horizontal and vertical directions, effectively eliminating the fire spread risk associated with traditional curtain walls due to inadequate fire resistance.

Through directional fiber optimization and physical consolidation processes, the material performance has been systematically upgraded. The A-grade non-combustible rock wool forms a physical fire isolation zone that prevents flame propagation. This panel meets the fire protection requirements of a wide range of industrial buildings while ensuring stable thermal insulation—achieving dual benefits of fire safety and energy efficiency.
The panel adopts a non-welded assembly process using mechanical interlocks for precise connections, avoiding heat deformation risks caused by traditional welding. The standardized prefabricated components feature reinforced grooves at the system joints, significantly reducing human error and enabling highly uniform large-scale facades. This supports the rapid construction or renovation of industrial buildings.
The modular assembly approach aligns fire zoning planning with curtain wall unit segmentation. Each unit's pure rock wool core naturally forms a fire-resistant boundary, effectively containing fire spread within its module and transforming the building façade into an active defense system.
The aesthetic design of the KEWONDER® curtain wall system is seamlessly integrated with functionality. The concealed tongue-and-groove jointing technique enhances structural integrity while eliminating visual breaks caused by exposed bolts. Horizontal lines become the dominant visual element, infusing the building with a refined, orderly architectural language.
Curved corner panels enable a smooth transition from rigid lines to flowing curves, while enhancing corner wind resistance. The matte metal texture combined with horizontal joint lines produces a rhythmic visual language that brings both strength and softness to industrial architecture, imbuing it with warmth and dynamic tension.
The geometric modularity of the curtain wall system allows for a balanced approach between standardization and customization, transforming the building façade into an extension of corporate branding.
Through structural innovation, material optimization, and process upgrades, the Four-Joint Pure Rock Wool Metal Curtain Wall Panel establishes a comprehensive envelope defense system encompassing fire isolation, structural stability, easy maintenance, and energy efficiency—delivering both safety and long-term performance for modern buildings.
As an innovator in architectural metal envelope systems, HEADSTREAM is committed to delivering precise, scenario-based solutions for diverse building applications.
By continuously advancing the integration of precision construction + digital prefabrication + scenario adaptation, HEADSTREAM empowers buildings to evolve from basic protection to value-driven spaces. Looking ahead, HEADSTREAM will remain dedicated to building safer, more efficient, and more sustainable infrastructure for industrial upgrades—supporting the high-quality development of China’s construction industry.
