Abstract
Traditional roofs can be effectively substituted by reinforced concrete roof slabs while gaining multiple advantages such as cyclonic resistance, possibility of future vertical extension and possibility of utilizing as an extra working space or a rooftop garden. Further, it adds a significant economic benefit from land regaining. However, the immediate space beneath the roof slab results in thermal discomfort and hence the inventions related to insulated roof slab systems have been increased recently. Although the expected thermal comfort could be achieved, most of the inventions use artificial thermal insulation materials such as polystyrene. This paper introduces a novel roof slab insulation system which uses the natural material of transversely cut bamboo layer as the thermal insulator. The proposed system minimizes the negative environmental impacts induced by the use of artificial insulation materials. The optimum insulation layer thickness is found to be 25 mm, which has acquired a 53% peak heat gain reduction with a decrement factor of 0.61 and a 3-h time lag.

Summary
Countries like Sri Lanka, located close to the equator, experience tropical climatic conditions having a higher humidity level with low seasonal temperature variations. Most of the Asian countries with such climatic conditions are rapidly developing countries with challenges such as energy crisis and scarcity of usable land for construction [1]. As a result of the damages caused by this development, global. The world is on its path of facing far worse consequences of global warming such as ice melting and rapid rising of sea level, abnormal precipitation, hurricanes and storms, floods and droughts [3]. According to the recent studies, failure to take necessary actions against global warming would result in a 1.1–6.4 °C rise of earth surface temperature by the end of the twenty-first century [4]. Countries like Germany have determined to reduce the emission of CO2 by 80% by 2050 [5]
