Shading coefficient meaning. However, SC differs from SHGC in some important ways.



Shading coefficient meaning. 87. Sep 16, 2024 · What is the shading coefficient (SC)? The shading coefficient (SC) measures the total amount of heat that passes through the glazing system (without taking into account the frame, sash, and other window parts) compared to the amount of heat that passes through a single clear glass. Shading Coefficient (sc) is Solar Heat Gain Coefficient divided by 0. 0. This term is being replaced by solar heat gain coefficient (SHGC). However, SC differs from SHGC in some important ways. It is a dimensionless value that ranges from 0 to 1, with lower values indicating better shading performance. . Feb 3, 2020 · Is Shading Coefficient the Same as SHGC? Previously, the industry used the shading coefficient (SC) as a measure but has since transitioned from SC to SHGC. It is a measure of the solar heat gain referenced to 3 mm clear glass which has the designated value of 1. Shading Coefficients The total shading coefficient is a measure of the total amount of heat passing through the glazing (known as the total solar heat transmittance) compared with that through a single clear glass. Despite their similarities in concept, the two are different. It is an indicator of how well the glass is thermally insulating (shading) the interior when there is direct sunlight on the panel or window. May 18, 2015 · Shading Coefficient (SC) Before the development of SHGC, the industry used SC to quantify the same concept. Aug 18, 2020 · The Shading Coefficient (SC) is a measure of the heat gain through glass from solar radiation. Mar 27, 2025 · Shading coefficient The shading coefficient (SC) is an older means of assessing the total amount of solar radiation passing through a glazing system (not including the frame) and is not commonly used now and has been replaced in literature by the SHGC. Specifically, the Shading Coefficient is the ratio between the solar heat gain for a particular type of glass and that of double-strength clear glass. The SHGC rating indicates the capability of the entire window, meaning the glass and frame, to resist the heat and light from solar radiation. SHGC can be expressed in terms of the glass alone or can refer to the entire window assembly. 00. The shading coefficient depends on the color of glass and degree of reflectivity. Similar to its successor, SC is a dimensionless ratio that can theoretically range from 0 to 1. Shading coefficient defines the sun control capability or efficiency of the glazing system relative to a standard window. Apr 9, 2025 · 4) Shading Coefficient (SC) Definition: The shading coefficient is a comparison of a window film’s heat gain reduction to that of clear glass, measuring its cooling load reduction capability. Shading coefficient is an alternative measure of the heat gain through glass from solar radiation. 00 to 0. May 30, 2024 · The Shading Coefficient (SC) is a measure used to quantify the solar heat gain of glass in comparison to a standard piece of 1/8 inch (3mm) thick clear glass, which has an SC of 1. It is usually a value ranging from 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits, and the greater its shading ability. Meanwhile, the SC rating only The shading coefficient (SC) is a measure used to evaluate the effectiveness of window treatments or glazing materials in reducing solar heat gain. zz axce c0bxccu hinyc uyka5 ysro yattl wxt7bylji eo4ah1 roa2
