FIELD: chemistry. ^ SUBSTANCE: invention relates to a double-glased window structure with high thermal efficiency. The insulated double-glased window has two glass sheets. The space between the glass sheets is filled with a low thermal conductivity gas. There is a cured sealing composition between the glass sheets and the element which seals the gas. Said composition is obtained by hardening a composition containing: a) at least one polydiorganosiloxane which ends with silanol; b) at least one cross-linking agent for the polydiorganosiloxane which ends with silanol; c) at least one intercrosslinking reaction catalyst; d) at least one organic nanoclay; e) at least one solid polymer whose gas permeability is less than the permeability of the cross-linked polydiorganosilixane. After hardening, the cured sealing composition has argon permeability coefficient of not more than approximately 900 Barrer. ^ EFFECT: high viscosity of the composition and low gas permeability of the sealing composition. ^ 17 cl, 1 tbl, 11 ex, 3 dwg |
