Profitable Lag Developed
Pyongyang, November 17 (KCNA) -- The complex lag developed by the Research Institute of City Management Science under the State Academy of Sciences is highly appreciated by the users for its economic effectiveness.

The lag is helpful to the protection of environment as it is made with various sorts of plastic wastes as raw materials.

It raises the lagging effectiveness two times or more, its production cost being low.

According to researchers, the application of the lagging materials to buildings and dwellings raises the indoor temperature by over six degrees centigrade as against the pre-application and increases construction tempo remarkably.

The lag was used as roof and wall lagging materials when the Taedongmun Cinema was reconstructed.
