What tests are required for curtain walls
Author:
1、 Curtain wall inspection items:
1. Building energy efficiency testing;
2. Safety performance of the main structure;
3. Limit of harmful substances in materials;
4. Curtain wall air tightness test;
5. Wind pressure deformation;
6. Water leakage;
7. Rain canopy;
8. Glass;
9. Fire prevention;
10. Seismic resistance.
2、 Acceptance criteria for curtain walls:
1. Building Energy Efficiency Testing
The thermal indicators of the building enclosure structure should meet the design requirements.
2. Main structure safety performance
The bearing capacity of the frame structure should not be the design value; The strength grade of concrete components should not be c20; The strength of both masonry and wooden components shall not exceed level 10. When using prestressing, the diameter and number of prestressed steel bars should be determined based on the force calculation and should meet the structural anchoring requirements.
3. Limit of harmful substances in materials
The building materials used comply with the current national standard "Radionuclide Limits for Building Materials", and it is strictly prohibited to use building materials and products that are explicitly prohibited by the state in the project.
3、 Precautions for curtain wall construction:
1. Before installation, conduct a comprehensive inspection of the building and promptly rectify or rework any non-conforming areas.
2. Do a good job in waterproofing and lightning protection measures for concealed works (such as lightning strips).
3. Take moisture-proof measures (such as making drip lines) to prevent rainwater from entering the wall and causing mold.
4、 FAQ:
What is an aluminum alloy louver installed on a concealed frame glass curtain wall?
Answer: (1) Hidden frame aluminum alloy louvers are louvers installed on hidden frame glass;
(2) The thickness of aluminum alloy materials is generally 1.5mm-2.0mm;
(3) The surface of aluminum materials is subjected to anodizing treatment;
(4) Aluminum alloy material has the advantages of good weather resistance and strong aging resistance.

How is witness sampling conducted?
Witness sampling is one of the supervisory management methods. Witness refers to the activity of on-site supervision by the supervising engineer on the completion of a certain process by the contracting unit. Witness sampling refers to the supervision activity of on-site sampling of materials, semi-finished products, and components related to structural safety used in engineering projects, as well as the inspection of the effectiveness of process activities.

What are the main testing items for building environment testing
Environmental testing mainly detects factors such as chemical pollutants and physical and biological pollution. Environmental detection and governance is a highly technical emerging industry that utilizes GIS technology to design environmental detection networks. The information collected from environmental detection can be stored and displayed in a timely manner through GIS, and detailed site monitoring and analysis can be conducted on the selected evaluation area.

What testing is required for building curtain walls?
Building curtain walls require physical performance testing (wind pressure resistance, air permeability, rainwater leakage, and plane deformation performance testing reports), which is generally referred to as the four properties testing of curtain walls, compatibility and adhesion testing reports of silicone structural adhesives and weather resistant sealants, and on-site tensile force testing reports of embedded parts.
