Study of Environmental Aspects of Protected Membrane Roof Structures.

Abstract

This report summarizes the results of an investigation to evaluate experimentally the thermal performance of protected membrane roofs under wet weather conditions. The objective of the investigation has been to measure the heat transmittance characteristics of protected membrane roofs during conditions of rain on the roof, during subsequent evaporative drying conditions, and for comparison, during dry weather, including different wind speeds. The results of the investigation serve to develop design information in parametric form which can be used for the preparation of construction criteria and standards, for planning and design purposes and for computer modelling of thermal performance under varying climatic conditions. The scope of the investigation has been to test characteristics protected membrane roof sections in an environmental test chamber under defined climatic conditions and recording the thermal performance characteristics.
