Samheri A. Redha Almuradi, Ameera Amer Hameed,

Abstract : Countries are spending a big share of their budget on energy consumption to sully heat during winter and cool during summer, particularly in the intermediate climate places. Disadvantages of traditional thermal insulation materials in addition to their cost, the health risks (wool glass), carbon dioxide emissions, and fire unsafe (petroleum polymers). Therefore, inspection of new insulation materials to overcome the above disadvantages becomes extensively needed. This study develops experimentally and numerically the disposable waste of tires as fibers, plastic bottles as grains, and agricultural wood waste as sawdust fibers for thermal insulation and compares it with air between 40cm x 40cm x 90cm inside dimensions of non-bottom double glazing box. The box is made of 4mm and 6mm thickness transparence glass sheets, separately, and supported by aluminum frames. The temperature property is measured inside, outside, and at interferences between waste material or air and glass. A heating source fixed at the box inside the central space of 60, 80, and 100W bulb lights is used. Thermal insulation performance is examined at three different waste material gap thicknesses of 8, 10, and 12mm to investigate its effect. Experimental results show that plastic waste grains gain the highest temperature difference and air has the lowest temperature difference, while other waste fibers graduate between them. It is noticed that temperature difference increases as material gap thickness increases except air. The results obtained from the present work nominate the examined waste types as cheap, clean, and sustainable environment, low carbon dioxide emission, fire safe (except sawdust) thermal insulation materials.
