FIELD: chemistry.
SUBSTANCE: invention relates to method of manufacturing heat-insulating, foamy materials. Pieces of glass are melted, melted mass is degassed by keeping it at temperature 1450°C for 10-60 minutes and are cooled to 950-1200°C. Overheated water steam, obtained from degassed water is passed through melted mass for blowing of great number of bubbles of different diameter from melted glass. Glass bubbles are cut off into form with formation of blocks, baked at temperature 450-600°C and cooled.
EFFECT: manufacturing of foam-glass with low values of heat-conductivity, acustic permeability and good light transmission, which last out for many years.
