T/JCJJ 022-2024 Insulation Structure of Laminated Rigid Glass Wool Board for Building Curtain Walls

Scope

Scope: This collection of drawings is applicable to the design, construction, and acceptance of exterior insulation projects for the inner wall base and main structural components of enclosed curtain walls in new, expanded, and renovated civil and industrial buildings, as well as existing buildings under energy-saving renovation projects in cold and extremely cold regions. Main technical content: The insulation materials adopted in this collection—curtain wall-specific rigid glass wool boards combined with composite fireproof cladding systems—are a resilient molded material made from glass fiber filaments with a diameter of less than 7 micrometers. As a curtain wall insulation system, it features the following characteristics: - High water repellency: The water repellency rate of curtain wall-specific glass wool exceeds 99%, ensuring the material's insulation performance. - Insulation and thermal performance: The small diameter of curtain wall-specific glass wool fibers results in lower thermal conductivity and superior insulation performance. - Fire resistance: Glass wool itself is classified as A-grade fire-resistant material, and after being coated with composite fireproof cladding, it can meet A2-grade fire performance standards. - Construction and installation performance: Due to the fine fiber structure and absence of slag balls, it is easy to cut, greatly improving installation efficiency, reducing labor costs, and shortening the installation period. - Installation and usage performance: The unit weight of curtain wall-specific rigid glass wool boards can be controlled, significantly reducing the self-weight of the insulation structure and improving the efficiency and safety of the manufacturing, transportation, lifting, hanging, and usage processes of curtain wall insulation. - Structural anti-vibration performance: The fine and elongated fibers of curtain wall-specific rigid glass wool boards ensure high overall structural strength, excellent tensile and s
