2.Limited use of wood as construction material
3.Higher speed of structure building
4.Saving 100% of funds spent for improvement of sound-proofless, heat-proofness,fireresistance and resistance to earthquakes. The material already possesses the above qualities because of its structure. The detailed description of the building material can be found in the attached copy of United States Patent #5,47 1,806.
demonstrate firmness of structure of the new material for in the case of external walls a harder material should be used as plates instead of drywalls.
When the panels are assembled as shown in FIG.1 (see the patent), with their ends facing one another a space 5 is retained due to the wedge-shaped recesses 4 between the ends of the panels, which space can be filled with a binding material such as foam gypsum, cement, plastic etc. In that way, structures are formed which bear most of the vertical loads. Therefore, there is no need for a skeleton of a building which eliminates using of wood.
