What are the contents to be done for curtain wall inspection

1、 Material testing
Glass inspection
Appearance quality
Check the glass surface for defects such as scratches, bubbles, inclusions, etc. For example, for tempered glass, serious scratches are not allowed, and there are corresponding standard limits on the size and quantity of bubbles.
physical property 
Test the optical properties of glass, such as transmittance, reflectivity, etc., to ensure compliance with building lighting and appearance requirements. At the same time, the strength of the glass, including its resistance to wind pressure, should be tested. For insulated glass, its sealing performance needs to be tested to prevent air layer leakage from affecting insulation and sound insulation effects.
Aluminum profile testing
mechanical property 
Test the tensile strength, yield strength, elongation and other indicators of aluminum profiles to ensure that they can withstand the load of the curtain wall during use. For example, based on factors such as the height of the curtain wall and the wind load in the area, the tensile strength of aluminum profiles should meet the corresponding design requirements.
Surface treatment quality
Check the thickness and adhesion of the anodized film or coating on the surface of the aluminum profile. Good surface treatment can improve the corrosion resistance and aesthetics of aluminum profiles. If the thickness of the anodized film is insufficient, it will reduce the weather resistance of the aluminum profile.
Sealing material testing
sealant
Test the weather resistance, water resistance, and adhesion of the sealant. For example, by simulating different climatic conditions, observe whether the sealant will crack, peel off, and other phenomena. The adhesion of sealant is directly related to the sealing effect of the curtain wall. If the adhesion is poor, it can lead to leakage of the curtain wall.
Sealing strip
Check the elasticity and aging resistance of the sealing strip. Sealing strips play a role in sealing and buffering in curtain walls. Insufficient elasticity can affect the sealing effect, while poor aging resistance can shorten its service life.
2、 Curtain Wall Performance Testing
Airtightness performance testing
Detect the ability of the curtain wall to prevent air infiltration. By creating a certain pressure difference inside and outside the curtain wall, measure the amount of air passing through the curtain wall per unit time. Curtain walls with poor air tightness can lead to excessive exchange of indoor and outdoor air, increasing the energy consumption of air conditioning and other equipment, and in areas with strong sandstorms, dust can also enter the room.
Water tightness performance testing
Mainly testing the ability of curtain walls to resist rainwater leakage. Observe whether there is any leakage in the curtain wall by simulating rainfall and applying certain pressure. Poor water tightness performance can allow rainwater to enter the interior of the curtain wall, damaging the structure and decorative materials inside the curtain wall.
Wind pressure resistance performance testing
Determine the performance of the curtain wall under different wind loads. Simulate wind loads of different intensities in the laboratory to detect the deformation of curtain walls and the reliability of structural connections. For high-rise building curtain walls, wind resistance performance is particularly important, as it relates to the safety of the curtain wall in strong wind weather.
Deformation performance testing within the plane
Evaluate the ability of the curtain wall to adapt to the deformation of the main structure in the plane. This is crucial for building curtain walls in earthquake prone areas. When the main structure undergoes in-plane deformation under the action of earthquakes, the curtain wall should be able to deform without damage.
Thermal insulation performance testing
Measure the insulation effect of the curtain wall. For buildings with energy-saving requirements, the insulation performance of curtain walls directly affects the energy consumption of the building. By detecting the heat transfer coefficient and other indicators of the curtain wall, determine whether it meets the energy-saving design standards.
Sound insulation performance testing
Detect the sound blocking ability of the curtain wall. According to the functional use of buildings, such as residential and office buildings, curtain walls should meet corresponding sound insulation requirements. By creating a sound difference on both sides of the curtain wall, measure the degree of attenuation of sound after passing through the curtain wall.
