Assessment of the Temperature of Waterproofing Membrane When A Recycled Crushed Glass Finish Layer Is Used on Flat Roofs to Protect from Sun Radiance

Abstract

The aim of this research was to determine the impact of the use of a recycled crushed glass finish coat on flat roofs to reduce the transmission of heat from sun radiance to indoor spaces in the buildings. This research forms part of previous studies carried out by LiTa on the application of cool roof products to reduce the energy required for air-conditioning inside buildings. Many flat roofs are finished with crushed stone aggregates of natural or artificial origin. The use of recycled crushed glass as a cool roof is potentially a double opportunity to reduce the environmental footprint: it is a recycled material and it may reduce air-conditioning demand. In order to evaluate the real efficiency of recycled crushed glass, this research compared the results with other technical alternatives that are generally applied in real conditions. © 2017 The Authors.
