Curtain walls and
doors & Windows processing
Curtain wall and doors & Windows production process
1. Material Inspection
Purpose: Ensure all incoming materials meet quality standards and specifications.
The first step in curtain wall production is to inspect the materials once they arrive at the factory. These materials typically include:
- Aluminum profiles
- Glass panels
- Sealants and adhesives
- Gaskets, fasteners, and other accessories
Key Points:
- Visual Inspection: Check for damage, defects, or discrepancies in color, size, or shape.
- Material Certification: Verify that materials conform to industry standards, such as ASTM (American Society for Testing and Materials) or ISO certifications.
- Measurement Check: Ensure the dimensions and thickness of the materials meet the project’s requirements.
- Quantity Check: Confirm that all required materials have been delivered in the correct amounts.
After the inspection, materials that pass the quality checks are sent to the next production stage.
2. Material Processing
Purpose: To accurately cut materials (e.g., aluminum profiles and glass panels) to the required sizes and shapes.
In this step, the raw materials are cut into precise dimensions to fit the curtain wall’s design specifications. This process involves:
- Cutting Aluminum Profiles: Aluminum extrusions are cut into specific lengths using CNC (Computer Numerical Control) machines or saws. The cut pieces are used for the frame structure of the curtain wall.
- Glass Cutting: Glass panels are measured and cut according to the size of the curtain wall units. Glass cutting involves precise machines that score and break the glass, ensuring smooth edges and accurate dimensions.
- Special Cuts: Some designs may require additional cuts, such as notches or holes for hardware, brackets, or drainage channels.
Key Points:
- Accuracy: Precision cutting is critical to ensure the components fit together correctly during assembly.
- Edge Treatment: Glass and aluminum edges are often treated or polished to prevent damage and ensure a clean fit.
3. Assembly
Purpose: To assemble the individual components (aluminum frame, glass panels, seals) into a complete curtain wall unit.
Assembly is a crucial stage where all components come together to form the curtain wall panels. The process typically includes:
- Frame Assembly: Aluminum profiles are connected to form the curtain wall frame. This may involve welding or using fasteners like screws and bolts.
- Glass Installation: Glass panels are carefully inserted into the aluminum frame. Gaskets or rubber seals are placed around the edges of the glass to create a secure, weather-resistant seal.
- Sealant Application: A high-performance sealant is applied between the glass and the frame to prevent air and water infiltration. The application of sealants is essential to ensure the curtain wall’s thermal and weatherproofing capabilities.
- Structural Reinforcement: Some curtain wall systems require additional reinforcements, such as structural silicone or steel supports, to ensure stability and strength.
Key Points:
- Precision Assembly: All parts must align correctly to ensure a proper fit and functionality.
- Quality Control: During assembly, continuous checks are done to avoid defects like improper fitting, misalignment, or damage to the materials.
4. Door and window sealing
Purpose: Ensure that all joints and connections are properly sealed to prevent air and water leakage.
After the curtain wall assembly, the sealant application process plays a key role in ensuring the wall’s performance, especially regarding weatherproofing. The primary steps include:
- Application of Structural Sealant: For some curtain walls, a structural silicone sealant is applied to bond the glass and aluminum frame.
- Weatherproofing: Other sealants are applied to joints and seams to prevent water penetration and air drafts.
- Curing: The sealant needs time to cure, ensuring it forms a durable, flexible bond between the glass and the frame.
Key Points:
- Proper Tooling: It is essential to apply the sealant evenly and use a smoothing tool to create a neat, consistent bead.
- Curing Time: The sealant needs adequate time to cure, depending on the type used (usually 24 hours).
5. Packaging and Shipment
Purpose: To protect the finished curtain wall panels during transportation and ensure safe delivery to the job site.
Once the curtain walls have passed inspection, they are carefully packaged to prevent damage during transport. The packaging process includes:
- Protective Wrapping: The units are wrapped in protective materials like bubble wrap, foam sheets, or shrink-wrap to prevent scratches, chips, or other damage.
- Frame Protection: Corners and edges of aluminum profiles or glass panels are often reinforced with corner protectors.
- Labeling and Documentation: Each unit is labeled with a unique identifier, and shipping documents (such as packing lists and invoices) are prepared for the delivery.
- Transport: Curtain wall systems are carefully loaded onto trucks for transport to the construction site. If the units are large, they may require specialized shipping arrangements.
Key Points:
- Secure Packing: Proper packaging is critical to ensure the curtain wall units remain undamaged during handling and transport.
- Timely Delivery: Efficient logistics are key to ensuring timely delivery to the construction site.
Conclusion
The production of curtain walls involves a series of well-coordinated steps to ensure that each unit meets quality standards, performs as expected, and arrives safely at the construction site. From material inspection to cutting, assembly, sealant application, final inspection, and packaging, each stage is carefully executed to provide a reliable, high-performance facade system for modern buildings. By maintaining rigorous quality control at every step, curtain wall manufacturers can ensure their products meet the demanding requirements of today’s construction projects.
