• Workmanship: Standards for design, fabrication, and installation to ensure durability, aesthetics, and performance.

25.2 Structural Glazing

• Components: Key components include glass panels, aluminium frames, structural silicone sealants, and gaskets.
• Design: Consideration of factors such as wind loads, thermal expansion, and building movement in the design of the glazing system.
• Fabrication: Precision cutting and fabrication of glass panels and aluminium frames to specified dimensions.
• Installation:
  • Framing System: Installation of aluminium framing systems, ensuring proper alignment and structural integrity.
  • Glass Panels: Fixing glass panels to the framing system using structural silicone sealants and gaskets.
  • Sealants: Application of structural silicone sealants to bond glass panels to the frames and ensure weatherproofing.
  • Testing and Quality Control: Conducting tests to ensure the strength and adhesion of the sealants, and inspecting the installed system for any defects.

25.3 Aluminium Composite Panels (ACP)

• Components: Key components include aluminium composite panels, sub-frames, fixings, and sealants.
• Design: Consideration of factors such as wind loads, thermal expansion, and building movement in the design of the ACP system.
• Fabrication: Precision cutting and fabrication of ACPs to specified dimensions.
• Installation:
  • Sub-Frames: Installation of aluminium sub-frames, ensuring proper alignment and structural integrity.
  • Panel Fixing: Fixing ACPs to the sub-frames using mechanical fasteners, adhesives, or a combination of both.
  • Joints and Sealants: Ensuring proper alignment and spacing of panels, and applying sealants to joints for weatherproofing and aesthetics.
  • Testing and Quality Control: Conducting tests to ensure the strength and adhesion of the fixings, and inspecting the installed system for any defects.

Examples:

1. Installation of Structural Glazing System:

   • Design: Develop a detailed design for the structural glazing system, considering factors such as wind loads and thermal expansion.
   • Framing System: Install aluminium framing systems on the building facade, ensuring proper alignment and structural integrity.
   • Glass Panels: Fix glass panels to the framing system using structural silicone sealants and gaskets, ensuring even spacing and alignment.
   • Sealants: Apply structural silicone sealants to bond glass panels to the frames and ensure weatherproofing.
   • Testing and Inspection: Conduct tests to ensure the strength and adhesion of the sealants, and inspect the installed system for any defects.

2. Installation of Aluminium Composite Panels (ACP):

   • Design: Develop a detailed design for the ACP system, considering factors such as wind loads and thermal expansion.
   • Sub-Frames: Install aluminium sub-frames on the building facade, ensuring proper alignment and structural integrity.
   • Panel Fixing: Fix ACPs to the sub-frames using mechanical fasteners, ensuring even spacing and alignment.
   • Joints and Sealants: Apply sealants to joints for weatherproofing and aesthetics, ensuring proper alignment and spacing of panels.
   • Testing and Inspection: Conduct tests to ensure the strength and adhesion of the fixings, and inspect the installed system for any defects.

3. Repair and Maintenance of Structural Glazing:

   • Inspection: Conduct a thorough inspection of the structural glazing system to identify any defects or damage.
   • Cleaning: Clean the glass panels and frames to remove dirt, debris, and any biological growth.
   • Sealant Repair: Replace any damaged or deteriorated structural silicone sealants, ensuring proper adhesion and weatherproofing.
   • Glass Panel Replacement: Replace any damaged or broken glass panels, ensuring proper alignment and bonding with the frames.

4. Repair and Maintenance of Aluminium Composite Panels (ACP):

   • Inspection: Conduct a thorough inspection of the ACP system to identify any defects or damage.
   • Cleaning: Clean the ACPs and frames to remove dirt, debris, and any biological growth.
   • Sealant Repair: Replace any damaged or deteriorated sealants, ensuring proper adhesion and weatherproofing.
   • Panel Replacement: Replace any damaged or deformed ACPs, ensuring proper alignment and fixing with the sub-frames.
