Solar reflectance index metal roofing

WebRoofing products with high solar reflectance and thermal emittance are referred to as "Cool Roof", which refers to an outer layer or exterior surface of a roof. As the term implies, the temperature of a cool roof is lower on hot sunny days than for a conventional roof, reducing cooling loads and energy required to provide air conditioning. WebKynar 500 ® based painted metal roofing can achieve solar reflectance of over 70%. Reflected solar energy allows the roof surface to remain cooler, which means less heat is transferred into the building. Cool metal roofing coated with Kynar 500 ® based resin is one way to limit the urban heat island effect. Urban Heat Island - a built environment where the …

WebSince roofs receive a significant concentration of incident solar radiation and are typically difficult to shade, they provide a natural focus to attempts to improve building solar reflectance. Other studies have identified solar reflectance as a primary property responsible for surface heat gain reductions (Anderson et al., 1991, Bretz et al., 1992). WebAug 23, 2024 · SRI = Solar Reflectance Index. Solar Reflectance Index (SRI) provides a guide of a surface’s ability to reject solar heat, on the basis of the relative temperature of surfaces with respect to a reference black (SRI=0) and white surface (SRI=100). The SRI value of a surface is calculated from its solar reflectance and thermal emittance.

This … WebAug 2, 2024 · Solar reflectance is the amount of solar energy or UV rays that is reflected away from the building, back into the atmosphere. The higher the solar reflectance is of a coating, the less heat the building has a chance to absorb. Thermal emittance is the relative ability of a roof to emit (or release) heat that has been absorbed.

WebOct 6, 2024 · Materials that absorb and retain solar radiation (which become hotter in the sun) have a lower SRI number. These tend to be darker colors, including black and dark browns. Highly reflective materials (which remain cooler in the sun) have a higher SRI number. These tend to be lighter colors, such as white or light gray. WebSolar Reflectance and Solar Reflectance Index measurements consider the amount of solar heat reflected from a roof and offer a way to compare different colors, coatings, and styles to see what fits your home best. These values are critical to understanding your roof’s performance in the heat.
