What is the shading coefficient?

In general, the shading coefficient is a scale of how well the glass windows or panels are thermally insulated. This is particularly important in determining how well the glass protects the interior of the building from heat generated by direct sunlight. The coefficient is influenced by several factors, including color, thickness and reflectance of glass. The shading coefficient indicates the ability of a particular glass pane to minimize the solar heat measured against 0.13 inches (about 25 mm) of the clay panel of clear glass. The coefficient is usually expressed as a number between zero and once. The lower the evaluation, the less solar heat is transmitted through and the greater its shading ability.

The coefficient is influenced by several factors. One such factor is glass color. Generally, darker colors or coatings on a glass are shading coefficient. This means that darker or tinted windows usually allow the transfer of less solar heat to the protected area.

Another factor that affects the coefficient is the reflectivity of the glass. There are some glazing that can be used to cover a glass that provide exterior reflective, mirror quality. This means that part of the solar heat is reflected from the window, increasing the coefficient. Glass thickness can also affect its ability to transmit solar heat and often stronger glass will have a higher shading coefficient, especially if a combination of toning or glazing is used.

Correct measurement of the shading coefficient of glass panels is particularly important in solving the problem with larger buildings. In general, there is a large building, such as a height office tower or the Indoor shopping center, has a lot of exposed glass in its design. As a result, there is a concern about the impact of solar heating on the interior cooling. If the glass panels used do not have a high shadow coefficient, it is likely that the interior of the building will be incredibly difficult to keep cool, especially runningEm hot summer months.

There are times when a lower shading coefficient is required. In other words, certain structures such as greenhouses or closed areas of the pool are trying to use glass panels that transmit solar heat rather than block them. In such cases, glass is used to have an extremely low shading coefficient to highlight generated solar heat.
