FIELD: construction.
SUBSTANCE: heat insulation glasing element comprises a system of glass sheets, the first of which is an external glass, the second one - an internal one, at least one third sheet arranged between the first and second sheets, spacer gaskets to adjust the distance between glass sheets, and a seal to seal the cavities between glasses from environmental impact. Glass sheets are arranged with internal surfaces. The glasing element is arranged as capable of pressure pulling in cavities below the outer atmospheric pressure. At least on one of inner surfaces at least one layer of a low-emission coating is applied, coefficients of solar radiation absorption A1, A2 of the first and second glass sheet comply with the requirement 0.3≤(A1/A2)≤4, and the third glass sheet is arranged with the coefficient of solar radiation absorption A3≤0.17.
EFFECT: invention will make it possible to increase glasing durability.
