Heat-absorbing glass
Energy efficiency in the construction industry is now the basis for the selection of materials, mainly glazing and windows. The low heat transfer coefficient of insulated glass Ug allows for high thermal insulation of the glass partition. Its value depends on the type of glass, spacer and the gas filling the air space. Heat penetrating through glass coatings is transported by infrared rays, which is why low-emission coatings, which do not limit natural sunlight, are so important. Heat-absorbing glass has unlimited use in modern construction due to the economics of modern buildings.
