Development of Roof Insulation Material from Low Density Polyethylene (LDPE), Kapok Fibre and Maerogel

Abstract

The roof thermal performance exerts a strong influence in controlling the building’s interior temperature. In Malaysia, people are suffering of the hot weather throughout the year especially during daytime. This research aims to develop the most effective roof insulation materials. In order to achieve that, three types of composite roof insulation samples are created through compression molding. Besides, tensile test and thermal conductivity test are conducted. Also, simulation of the thermal performance of the composites are done by using Autodesk Ecotect. All of the composites are found to be effective as they capable to maintain the indoor temperature at lesser than 34°C which is the limit of acceptable thermal comfort temperature limit (Makaremi, Salleh, Jaafar, & GhaffarianHoseini, 2012; Wijewardane & Jayasinghe, 2008)
