Methods of glass fire resistance improvement with preservation of its operation characteristics are considered on the basis of foreign and Russian patents review. Trends of conducting investigations, development of compositions of glazing, providing high fire resistance and thermal effect level are reflected in the article. Ways to improve such characteristics as the ability to reflect infrared radiation, the transparency of the glass for a long time, the ability to absorb impact energy, increased resistance to aging are proposed. Elaborations providing to improve the producing process
