Comparative Analysis of Various Insulation Materials for Building Envelope Components

Due to growing environmental and economic concerns in recent years there has been a renewed interest in building energy efficiency as building contribute a huge consumption of energy across world. Among the effective and compatible ways of energy conservation technologies available today, insulation of buildings is most relevant as it also reduces negative environmental impacts and annual energy costs. The building envelope comprises of different components which are pre-dominant in evaluating thermal performance of a building. A proper selection of insulation materials results in a low energy demand process. In any material selection procedure, the ultimatum is of addressing material properties, parameters, criteria and performance characteristics. Hence this study aims to provide a knowledge base on identified insulation materials for corresponding building components with respect to material properties and performance parameters and recommend best material. Study presents comparative analysis of insulation options available for various building components.
