Reflectance, Reflectivity, and the Solar Reflectance Index
WebOur lab is SAC-SINGLAS (ISO 17025) accredited and our customers are from around 30 countries. Solar reflectance index (SRI) is an indicator of material surface temperature under solar radiation. It is useful in urban heat island (UHI) effect mitigation.

Roof paint measured by the SRI index would normally be a figure between 0-100. However the scale goes beyond, so a very hot material can actually have a negative figure and very cool materials can have values greater than 100. bisho hospital contact number

WebOct 16, 2024 · SIST EN 12691:2024. This European Standard specifies a test for puncture by impact on sheets for roof waterproofing. Mechanical stress on waterproofing sheets ranges from static long-term loads to dynamic short-term loads. This method represents the dynamic category of load where puncture may be caused by impact. WebSolar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or resist the radiation.
