Potentially the glass is a very durable material. However, its strength to a large degree reduces in the presence of small, invisible surface defects which are called micro-cracks. These micro-cracks serve as points of stress concentration in the glass and source of spread the cracks. In addition, the strength of glass can also be weakened by visible defects.
Most breakage occurs for one or more of the following reasons:
- Defects on the surface/ edge
- Welding splashes
- Items flown by air
- The contact of the glass with metal
- Thermal stress
- Foreign impurities
- Acts of vandalism
To minimize the risk of breakage, before processing, you must follow certain rules:
- Analyze thermal stresses.
- Comply with the rules of storage of glass: in a dry and ventilated place protected from direct sunlight or high humidity.
- Observe precautions for transportation and storage of glass
In the process of glazing you should:
- Not put a frame with glass so that the edge was in contact with foreign objects
- Avoid contact of the coating with other materials except certified sealants
- Not install glass in non-heated premises
- Avoid dark, absorbent layers on glass
During operation of the building:
- Curtains, shades or visors, located adjacent to the translucent structures, potentially can cause thermal shock. Overheated and cool air acting simultaneously on the glass can cause its destruction. There should always be space for air circulation.
- Do not point the fan or air conditioning directly on the area of glazing.
How to avoid destruction?
In the section characteristics of products provides information on the exposure glass, the effects of thermal shock. When you determine the type of glass, we recommend you to contact the representative of our company for consultation and calculations for thermal shock.
