When storing and installing windows, it is essential that the work is carried out carefully, to prevent the appearance of defects that can affect the integrity and aesthetics of the products. The party responsible for the installation, be it carpentry workshops or construction sites, must take appropriate measures to avoid accidents and defects that may occur during the handling of the windows. Next, we will detail the main causes of defects that can occur and that must be prevented.

1. Scratches on the Glass Surface

Scratches on the outer face of thermal insulating windows (#1 and #4 #6) can occur for various reasons, including:

• Moving windows on abrasive surfaces: If the glasses are moved on surfaces containing abrasive particles, they can produce fine scratches on the glass.
• Cleaning with dirty cloths or abrasive elements: Using the wrong cleaning materials can leave marks on the surface of the glass.
• Contact with mounting tools: During installation, the tools or implements used can scratch the glass if not protected or handled correctly.
• Accidents and lack of protective measures: Failure to take protective measures at the site may result in accidental damage to the glass.
• Improper cleaning conditions: Cleaning windows in unsuitable environments or with aggressive products can affect their finish.

2. Incandescent Splashes

Molten metal spatter from activities such as welding or grinding is another danger to the integrity of the glazing. They can penetrate the glass, leaving permanent marks on its surface if adequate protective measures are not taken. It is important that the glass is protected during these processes to avoid damage.

3. Traces and Fingerprints on the Glass Surface

Fingerprints and marks on the outer faces of windows can have several causes, including:

• Suction cups or handling devices: Using suction cups or other handling equipment can leave visible marks on the windows.
• Adhesive labels: In some cases, labels applied to glass can leave adhesive marks or even damage the glass surface if not removed properly.
• Fingerprints or handling with dirty gloves: Many times, the windows are handled without observing hygiene rules or without using protective equipment, thus leaving visible marks.

4. Visibility of Joining Elements on the Glazed Surface

In the case of insulating glass, joints may become visible depending on:

• Position of the window in the frame: If the glass is not positioned correctly, the joining elements can become visible, affecting the aesthetic appearance.
• Frame height: Also, the height of the folds can influence how the joining elements of the glazing are perceived.

5. Absence of parallelism of the bars of the carpentry at the edges of the carpentry

If the purlin bars are not properly aligned at the edges of the joinery, this can result in a visible flaw in the final hardware structure. This may be due to the wrong position of the glass in the folds, thus affecting the aesthetics and functionality of the entire assembly.

6. Staining the glass

In anaerobic environments, when water stagnates on the surface of glass stored without separators, spots can appear on the glass. These stains are signs of a superficial attack that can alter the optical properties of the glass. The correct storage of the windows, with a suitable separation system, is essential to prevent these defects.

7, Defect Prevention Measures

To prevent these defects from occurring, it is important that assembly and storage teams follow a set of clear rules:

• Handling with care: The windows must be handled carefully, using appropriate protective equipment (suction cups, clean gloves, etc.).
• Correct storage: The windows must be stored in a dry environment, protected from dust and dirt, on supports that prevent direct contact between them.
• Protective measures during work on the site: When welding or grinding work is carried out, guards must be used to prevent molten metal splashing onto the windows.
• Proper cleaning: Cleaning windows must be done with appropriate products and equipment, without damaging their surface.

In conclusion, by observing strict storage and installation rules, most of the mentioned defects can be prevented, thus ensuring the durability, functionality and aesthetics of the windows in the long term.
