Development of an Effective and Eco-friendly Thermal Insulation for Thermal Comfort

Abstract

Thermal Insulation is defined as a material or combination of materials, which retard the flow of heat .Thermal insulations, can play an important role in regulating the building temperatures for human comfort, thereby substantially lowering the energy demands and associated greenhouse gas emissions. Environment friendly insulations can be built. when there is an increased usage of biodegradable renewable resources. In residential and industrial buildings and offices, substantial energy consumption occurs due to space cooling and heating requirements for process or for comfort conditions.For reducing the building energy demand, it is necessary to increase the energy efficiency of complex element in envelopes both in their production and operational conditions. Energy saving is essential because of an increasing amount of usage of the limited non-renewable fossil fuels as well as an increased environmental pollution caused due to an increased usage of the non-renewable energy resources for the generation of electricity in power plants. For instance,in 2005, structures emitted 8.3 Gt carbon dioxide every year representing more than 30% of the nursery gas discharges in numerous created nations.In the present study the relative contribution of various eco- friendly materials in preparation of thermal insulation was established. It was observed that the presence of paper pulp in thermal insulation lowered the thermal conductivity and density, while increased the compressive strength and horizontal burning rate. The horizontal burning characteristics can improve by adding boric acid to the sample.The optimum sample was prepared by mixing paper pulp with wood ash for overall performance.
