Pyongyang, October 13 (KCNA) -- The Branch Institute of Construction and Building-Materials under the Academy of Sciences of the Democratic People’s Republic of Korea has developed lagging materials with foam from plant-steeped water.
It’s some type of thermal insulation, I guess. Looks like somebody discovered it while making grass soup.
Its heat conduction is 0.08 watt per meter kelvin. It does not break under the pressure of five mega Pascal. It has been widely used in the newly built factories, dwelling houses and stockbreeding farms including the recently face-lifted Yonggwang Street.
That’s nice, Yonggwang Street was looking a bit shabby.
Its raw material is inexhaustible in the country.
We got plenty of grass!
Its production cost is low but the quality is good.
Quick, call the Nobel Committee! |
