Vermiculite와 각종 건축재료와의 단열성(斷熱性)에 대한 비교 연구 = Study on Insulation by Comparing Vermiculite with Various Building Materials

다국어 초록 (Multilingual Abstract)

Building and heat have a close connection with eaca other. The latter has a great influence upon making up the surroundings in our daily lives.
Drawing up plans for protection against the cold and the hot is a matter of consequence in building.
So we must give careful consideration to the choice of matterials for making the wall.
For this, by comparing insulation of vermiculite with that of various building materials. thermal conductivity of Vermiculite is 0.05(k cal/m·h·℃), and on the condition of wall Fig 10, K, total heat transmission coefficient, and Q, total transmission calorie are as follows:
K = 0.552(K cal/m^2·h·℃)
Q = 5.52(K cal/h)
Thus Vermiculite, a mineral matter, of which total transmission coefficient is low, is an insulating material never spoiled and deteriorated. Moreover as it is easy for us to purchase the material, Vermiculite is very useful for the wall material.
