Tin roofing has a high heat transfer rates. Under direct sunlight these roofing heat quickly which in turn increases the room temperature, in cold days it allows heat to escape easily. Thermal insulation provides protective shield to reduce the transfer of heat from inside to outside and vice-versa to maintain an optimum room temperature. An insulated room is more comfortable as the temperature remains consistent over weather changes. It keeps the temperature of room cool in summer and warm in winter. It is very useful to keep the temperature of the room independent from outside temperature. People are known to suffer from heat stress, dehydration and many other heat related problems. The project deals with data collection of conditions in a classroom and study of use of thermocol as roofing material and provide false ceiling in a test site in a community school. 2 OBJECTIVES Study and installation of thermocol insulation in community schools 1. 2. 3. 4. Study usefulness of thermocol as roofing material. Data collection of temperature conditions. Indentify site in community school to test the material. Install false ceiling of thermocol in the site. SCOPE 1. 2. 3. 4. This project indentifies a problem in community and provides a solution. This project is for research grant application and funded by it. The project deals with teaching the beneficiaries with long term use and maintenance of product. The project intends to evaluate results of project by questionnaires. INTRODUCTION Thermal insulation in buildings is an important factor to achieve for comfort of its occupants. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. Insulation can be referred to as slow heat loss and the insulation materials employed for such are: cellulose, glass wool, rock wool, polystyrene, urethane foam, vermiculite, perlite, wood fiber, plant fiber (cannabis, flax, cotton, cork, etc.), plant straw, animal fiber (sheep's wool), cement, and earth or soil. Insulation provided in a building depends upon building design, climate, and energy cost and personnel preferences. In cold conditions, the main aim is to reduce heat flow out of the building. In hot conditions the main aim is to increase heat from the building. Anyone can suffer from heat related illness, but the most at risk are: People over 65 years living alone or without air conditioning, babies and young children, pregnant and nursing mothers and people on medication on illness. General Principles of Thermal Insulation • Thermal resistance of an insulating material depends on the type of material and the thickness. • Provision of an air gap is very important and useful insulating agent. • Orientation of the building has important role in thermal resistance. • The building/house design is done in such a way so that entry of solar energy in summer should be minimum and in winter it should be maximum. Choice of Insulating Materials Choice of insulating material depends on following considerations. • Cost of insulating material. • Area to be covered for insulation. • Standard of insulation to be required. 3 • Cost of energy consumed for heating and cooling. • Reasonable fire proof • Non absorbent of moisture • Not liable to undergo deformation • Resistant to attack of small insects Insulating Material •Rock wool. • Slag slabs • Mineral wool slabs • Aluminum foils • Cement concrete block with lightweight aggregate. • Gypsum board • Asbestos cement board • Clip board • ACC cement board • Chip board • Foam glass • Gasket cork sheet, foam plastic etc. Properties of thermocol are : Thermal conductivity at 10 mean temperature Compressive strength Cross breaking strength Tensile strength Application range Water absorption by % volume for 7 days in water Self ignition point Melting point 0.028-0.031 Kcalm/hr. m c 0.8-1.6 Kg/cm 1.4-2.0 Kg/cm 3-6 kg/cm -200 +80 C 0.5% 300 C 100 - 200 C 4 STATEMENT OF A PROBLEM G.I sheet is common roofing material in many parts of Nepal. Tin roofing has a high heat transfer rates. Under direct sunlight these roofing heat quickly which in turn increases the room temperature, in cold days it allows heat to escape easily. Thermal insulation provides protective shield to reduce the transfer of heat from inside to outside and vice-versa and maintain an optimum room temperature. An insulated room is more comfortable as the temperature remains consistent over weather changes. It keeps the temperature of room cool in summer and warm in winter. It is very useful to keep the temperature of the room independent from outside temperature. This project deals with study and installation of thermocol as insulating materials in roofing. The project identifies the problems faced to maintain room temperature under G.I sheet roofing. It intends to study usefulness of thermocol to maintain ambient temperature conditions in class rooms and install a false ceiling in it. Site selected for testing and installation of false ceiling of thermocol is a hall of community school Kirtipur Madhamik Vidyala ,kirtipur in which a child care center is operational. Kirtipur Madhamik Vidalaya is a public school established in 2025 B.S in Kirtipur. The principal is Mr. Janardhan Shrestha. The school holds classes from 1 to 10. It operates child care center between 10 am to 3 pm for 22 students. The child care center is operated in a hall of dimensions 9 m * 7 m. The roofing material used is G.I sheet. The hall has no false roofing. Hence the room is subjected to weather changes. The temperature is high is summer and is cold in winters. The hall has been identified as test site for use of thermol as roofing material. Calculations and budgeting is done to provide false ceiling for the hall. Hence the problems encountered are as follows: 1. 2. 3. 4. 5. 6. 7. High expenses to provide concrete ceiling in community schools. Small rooms and oversized class population in community schools. Use of G.I sheets for roofing material without false ceiling. Lack of airflow and sun exposure in G.I roofing systems. Lack of proper thermal insulation in community schools. Power cuts and inadequate devices such as fans and heaters. Dehydration leading to heat related illness includes dizziness or fainting, heat exhaustion heat stroke and worsening of existing medical conditions in summer. 5 METHODOLOGY S.N.
