Vacuum insulating glass manual

Vacuum glass is new type of architectural glass and is applied in more projects,especially windows restoration,refirgerators,and new buildings.Different from laminated glass or insulated glass which has PVB or sealant that is soft materials to work as buffer and relief the shocks and deform, vacuum glass has rigid connection between two glass panels,whether it’s glass solders or metal sealing.So many problems will happen if improper handling,transportation and installation,here is a vacuum insulating glass manual to avoid breakage .

Tempered vacuum glass will break into fragments after serious impact,the fragments counts in a area of 50 50mm is 65

Vacuum insulating glass has been well packaged and protected before leaving the factory:Glass are packed with firm and high-quality wooden box. Glass is separated by foam or other soft materials to ensure the safety during  long term transportation. Please read the “Vacuum Glass Installation and maintenance Manual” in detail upon receiving the glass and operate according to the requirements.

Vacuum Glass Installation and maintenance Manual

1. Packing listis stick on wooden crate side,marked with case number, customer name, project name, product configuration, ref remark, size, quantity , area, well with rain-proof, fragile, direction markings.

      2.Transportation:Avoid squeezing and shocks during transportation, and handle it carefully. Avoid raining on glass & crates directly. When transporting, the glass length direction should be consistent with the vehicle  driving direction,Keep balanced weight to prevent falling down. Horizontal transportation is prohibit .

     3.Storage:The vacuum glass that has not been installed should be stored in a clean, cool and dry room, and free from shocks. Keep ventilation in high humidity and high temperature conditions.It is forbidden to store glass together with chemical products. The glass and wooden boxes should be kept upright, and their angle should be 5 degrees from the vertical. Glass should be covered with plastic film when installation is not finished, avoid glass get wet or crashed .

    4.Installation:During the installation process, pollution and crash should be avoided. Vacuum glass must be handled vertically (the angle with the horizontal direction is greater than 45 degrees), and it is forbidden to handle glass in horizontal direction. Do not let ropes and other construction equipment directly contact the glass during installation; it is recommended to stick a protective film on the glass surface during the gluing process; Acid sealant is forbidden.

Vacuum glass should be handled in vertial direction

When installing glass to the window frame, the edge of the vacuum glass should not be in direct contact with the hard-surfaced profile such as aluminum and metal, and a soft support materials(such as sealant or rubbers) should be added, and the glass load-bearing edge (mostly the bottom edge) should have uniform force. Appropriate space should be reserved to work as buffer space between glass &windows frame.

The installation operation should use non-metallic and rubber-like tools for auxiliary installation. Workers should operate gently, avoid impact on the glass. The contact force between the glass sides and the window frame should be uniform to avoid the windows deforming. The vacuum glass should be fixed with the window frame in time, and when the vacuum glass is installed in the opening fan, the opening fan and the window frame must be locked or fixed to avoid potential damage caused by wind.

5. Further processing:Vacuum glass can be further processed into hybrid insulated glass or hybrid laminated glass. Glass cleaning must be done with a soft brush and neutral detergent (deionized water is recommended).

Other further processing-Cutting,Holes,bending,tempering process is strictly prohibited.

6. Maintenance:Avoid using solvents that contain acids, fluoride salts, or hydrogen fluoride when cleaning glass. Indoor heating and cooling devices should keep a certain distance from the glass. Avoid direct blowing of hot and cold air to the glass surface, which may cause the glass thermal breakage.

Please follow above storage and transportation, and installation, further processing and daily maintenance rules according to above manual. We are not responsible for quality complaints beyond the scope of normal use and processing.
