This research is an experimental research aimed to compare the performance of thermal insulation produced
from the rubber tree with thermal insulation commonly used. The study conducted using laboratory size
3.50 m. long, 5.00 m. height 2.50 m. in a laboratory size 1.00 x 2.00 m. Number four lab
laboratory was the heat shield on the north, east and west. The south side is only one side
to install experimental material. Laboratory environment similar and no air conditioning laboratory first install
insulation rubber leaves 1 inch thick and three laboratory install fiberglass insulation, 2 inches thick wool insulation CELLOCRETE 1 inch thick
and insulated posts. Lee polyurethane foam one inch thick in order to keep the thermometer. Collect data every two minutes,
two days or 48 hours from the experiment. Insulation manufactured from the rubber tree. Effective in
preventing heat transfer is similar to fiberglass insulation at a thickness of 2 inches from this research can be applied
to guide the production and development of thermal insulation from the rubber tree or materials agricultural residues other. so
to save energy in buildings by the farmers. And people generally interested can produce up personally.
