There are a variety of factors that can cause a thermal stress break, including the type of glass used, the type and location of the coating, shading patterns, and technological devices.

Glass, for all of its versatility and performance, requires the application of a number of specific considerations when it is being worked with. In commercial construction, it is common practice to specify large glass panels in order to make a dramatic visual impact. A thermal stress break is a type of thermal stress break that can be used.

A thermal stress break occurs when the center of a window unit's glass is hotter than the edge of the glass within the unit's framing, resulting in an expansion thermal stress break in the glass. Glass edges may be broken at a 90-degree angle from their original position due to the increased tensile tension caused by the increased tensile tension on the glass edges.

Vitro Architectural Glass (previously PPG glass) recommends that close collaboration with the fabricator be established at the outset of the design phase, as well as the completion of a thermal stress analysis of the glass. Using the free thermal stress analysis tool provided by Vitro Glass, anyone can assess their own thermal stress. As a result of this fundamental investigation, the appropriate glass is selected for the project's anticipated thermal stress loads.

The following are additional factors that influence the resistance of glass to thermal stress breaks:

Colors ranging from ultra-clear to dark gray are available in a wide variety of glass types. As a result of absorbing solar radiation, these glasses become hot to the touch. Shaded glasses are more susceptible to heat stress than clear eyeglasses as a result of this heat absorption.

Reflective or low-e coatings on the outer (or inner) pane of an IG can alter the amount of solar radiation that is received by the pane, thereby altering the thermal stress concerns that are associated with it.

Outdoor Shading Patterns Change with the Seasons: This is a dynamic aspect that changes with the changing of the seasons. As an alternative solution, it is possible to reduce the amount of space where less than 50% of the glass panel is shaded by lowering the ceiling height. As a result of this, temperature gradients will be less pronounced.

Glass temperature can be raised by the use of indoor shading devices such as blinds or drapes in the same way that it can be raised by using exterior shading patterns on a window. The phenomenon occurs when a window blind or shade reflects the sun's rays back through the window glass, thereby limiting convection and conduction inside of a building.

Placing the Heating Registers Properly: The registers in every structure must be properly placed in order to avoid hot air being directed onto the glass, which can cause damage to the building.

Additionally, the use of a framing system with a low heat capacity will reduce the likelihood that a break will occur in the structure.

Vitro Glass strongly recommends that a thermal stress analysis be performed early in the design process, and that you collaborate closely with your glass fabricator throughout the process. Vitro Glass has made a free thermal stress analysis tool forinsulated glass unit  available to anyone who wants to use it.

When it comes to thermal stress breaks in the glass units that you specify, it is a straightforward calculation that can help reduce the likelihood of thermal stress breaks in the units that you specify. To reduce the likelihood of thermal stress breakage, you can either modify your design or use heat-treated glass to reduce its impact.
