EXECUTIVE SUMMARY: This study entitled "Development of Coco Coir Polypropylene as Thermal Insulator" was carefully designed for the purpose of producing alternative insulator using expendable materials available in the environment. Its aim was to find out the level of performance and to determine the level of acceptability of the insulator fabricated using coco coir and straws. The study utilized coco coir and straw into an alternative insulator and determined its thermal insulation capacity, fire resistance and acceptability in terms of appearance, usefulness and safety. The methods applied on this study are developmental and experimental research design. The developmental design was used to improve the products. Experimental design was used to test the effectiveness of the developed insulator. The researchers conducted specific tests and improvised methods in evaluating the output's thermal insulation and fire resistance capacity. These helped them assess the developed insulator's quality. It was determined that in terms of level of performance, the developed insulator exhibits thermal resistance that through actual comparative performance test executed shows that the developed product taking into account that it provides a much cooler inside temperature, has a slow rate of heat absorption. The output's acceptability in terms of appearance, usefulness and safety were appraised through the used of questionnaire. There are three (3) groups of respondents who were selected for the evaluation of the alternative insulator's acceptability in terms of its appearance, usefulness and safety. The first group includes five (5) professionals who are in line of civil engineering and construction industry. The second group of respondents was composed of five (5) skilled workers related in the construction industry and the third group of respondents includes five (5) end users. The result shows that the developed insulator is Very Much Accepted in terms of appearance, usefulness and safety for Professional respondents which received an average weighted mean of 4.2. Skilled workers had given the research an average weighted mean of 4.27 in terms of all category which is verbally interpreted as Very Much Acceptable. End users had given the research a weighted mean of 4.57 verbally interpreted as Very Much Acceptable also. The cost analysis shows that the production of the developed insulator was more expensive than the commercially available insulator. The principal conclusion was that the developed insulator has the ability to insulate heat therefore making it an adept thermal insulator. And for further studies, the researchers recommend the use of machine in fabrication, other kinds of binding agent and digital temperature thermometers for the improvement of the research.
