1) Hide acceptance request.

2) The quality of curtain wall materials, accessories, accessories and components, including thermal insulation materials, glass, sunshade components, unit curtain wall panels, sealing strips, thermal insulation profiles, etc.

3) Requests for witness sampling and re-inspection of documents, accessories, attachments, and components.

4) Request for air tightness of curtain wall, request for inspection by laboratory.

5) Curtain wall thermal structure request, including insulation material device, vapor barrier, joints between the periphery of the curtain wall and the wall, structural joints, structural joints, thermal bridges, thermal insulation nodes, joints between unit curtain wall panels, condensation Water collection and drainage structure, etc.

6) Requests for construction installations, including fixing of insulation materials, thermal insulation bridges, vapor barriers, ventilation devices, glass installations, shading installations, condensate collection and drainage system installations, etc. The curtain wall is composed of a structural frame and inlaid panels, and is a building envelope structure that does not bear the load and role of the main structure.


The glass curtain wall project, many people will think of it as a big project, but what we are engaged in are those small events that are forgotten by people, such as curtain wall replacement, glass replacement, door and window repair, door and window hinge replacement, replacement project, maintenance In terms of engineering, maintenance and reinforcement, the old curtain wall is basically strengthened, the aluminum alloy is basically strengthened, the stainless steel is basically strengthened, the curtain wall is treated with water seepage, the glass self-explosion repair project, the construction of the sun room, and the construction of the steel factory shed. The building curtain wall is composed of a supporting structure system and panels, which can have a certain displacement relative to the main structure, and does not share the building envelope or decorative structure that the main structure is subjected to. Our advantage: In terms of personnel, most of our engineering personnel have more than 6-7 years of construction lessons, and the average age is 27-40 years old.


Everyone knows that curtain wall repair is a difficult task. The age of our personnel was the golden stage of life. Therefore, if our insurance measures are in place, then our advantage will be known regardless of the price. Advantages, our company’s combination is very simple, unlike many companies with a very ambitious organizational structure, but in that case, it will increase your maintenance cost invisibly. For the small amount of work of the family and the company, that would not be the case. A good choice.


Maintenance is to calculate the cost. If it is too high, then there is no need to repair it. Just buy a new one. However, if someone can provide a one-stop service that is not very expensive, then I think it is the one that many people are willing to accept. event. High-quality insulating glass has good energy-saving effects on the one hand, and long-lasting and sealing life. If the insulating glass has good energy-saving performance, but the long-term and sealing life is short, it is also a low-grade insulating glass. On the contrary, if hollow The energy-saving performance of glass is good, but the durability and the short sealing life are not what we want. High-quality insulating glass should have both better energy-saving consequences and the longest sealing durability.  


The quality of insulating glass should be distinguished from the following two aspects: supporting materials and process quality. At present, most of the insulating glass on the market adopts the double-pass sealing process. For double-pass sealed insulating glass, the supporting materials include: glass, metal spacers (or composite rubber strips), and adhesive sealant (butyl rubber) , The second bonding sealant (polysulfide glue, silicone rubber or polyurethane glue), desiccant (molecular sieve), connectors. The quality of the workmanship mainly includes: the quality of the seal, the quality of the second seal, the quality of the corners and the interface. For the judgment and evaluation of process quality, we should judge a premise that no matter which sealing problem presents, the insulating glass sealing will take effect.  


To distinguish the quality of insulating glass, we must first inspect the overall appearance quality of the insulating glass. The inspection of the appearance quality mainly includes: the appearance quality inside the insulating glass, the quality of the inner and outer sheets, and whether there is any misalignment of the inner and outer sheets. , The appearance quality of the hollow spacer strips.


Place the hollow glass under good natural light or sunlight to check the cleanliness of the hollow glass, whether it is clean and free of impurities. The inside of the hollow glass must be clean and transparent and free of impurities. If the internal cleanliness is poor, there will be dust It may be judged as a failing product with impurities. 

 

First, check the edges of the inner and outer sheets of glass. There should be no obvious shell-like (larger than mung bean) bursts on the inner and nominal edges of the glass. If you want the glass to have a certain strength and safety, it is better to choose The inner and outer sheets of glass are tempered insulating glass; secondly, the thickness of the inner and outer sheets of hollow glass is selected. The choice of thickness depends on the area and size of the insulating glass. The larger glass should be thicker. The building curtain wall is composed of a supporting structure system and panels, which can have a certain displacement relative to the main structure, and does not share the building envelope or decorative structure that the main structure is subjected to.


There is no dislocation of the hollow inner and outer glass sheets, and the edges should be clean, and no obvious dislocation is allowed.
