This research Local knowledge is the second thing is to use natural materials like bamboo roofs with upturned keel Coating bamboo powder mixed with oil, chemical applications. To enhance waterproofing and preserving meat bamboo from insects and air pollution. Adjust the installation of roofing material provides an easy-to-use device with a common roof to roof. The choice of natural materials, roof replacement, roof tiles damaged by natural disasters. Roof tiles are two kinds of material mixed with asbestos cement type Roofing. Bamboo roofs and upturned keel Topped by a 30-degree slope on the roof steel boxes with screw fasteners are used in rubber roofing generally facing slope to the south, the direction of the sun throughout the year. Set outdoors in natural surroundings of Bangkok. Tests comparing the temperature and humidity occurring in test box. Install equipment to measure and record temperature and humidity. Continuously for 90 days,
test results showed that bamboo roofs coated with a layer of paint mixing oil. Effectiveness of different insects and topsides permeate the meat rather than split bamboo canes that do not apply the coating. And study the climate of the two types of roofing materials that bamboo roofs are prone to supine low mass material is transmitted through the heat and humidity than asbestos roof tiles with a mass medium. There conductivity and low heat reflection. This makes bamboo roof, heat and cooling is not much faster. The time delay of heat (Time leg) less daytime average temperature of the central roof bamboo house upside down facing the house under roof tiles Roofing 1-2 degrees Celsius in the average temperature at night the roof of bamboo upturned face. above the roof tiles and Roofing 1-2 degrees Celsius maximum temperature of the outer surface and the inner surface of the bamboo turn upside down under the roof tiles and Roofing at a prominent place (in the range of 3-4 degrees. c) plus the amount of moisture absorbed into the body over the bamboo at night and released during the day. Resulting in better thermal comfort inside the building.
