(57) Abstract:Usage: the invention relates to window constructions with single, paired or separately-coupled covers with double or triple glazing installed in window openings of buildings. The inventive between the glasses of the window block, forming a vertical air layer, placed a screen of translucent sheet material mounted on the cover and fill the lower part of the height of the air gap in the window opening. Following formulas to calculate the magnitude of the air gap blocked by a screen, which is determined from the conservation of optical properties in the checking points of the premises and of increasing thermal resistance of the window with the screen. 1 Il. The invention relates to window constructions with paired, separate or separately-coupled covers with double or triple glazing and can be used in construction for installation in window openings of buildings.Known glass to improve thermal zone which layer in its lower zone separated by a screen of translucent sheet material, zakreplennye 0,2 height glazing and the distance between the screen and the glass, not exceeding 10 mm, the heat-shielding properties window was increased by 2-5%
Higher thermal properties of the glazing unit, comprising parallel spaced glass and spacer frame between them, equipped with a screen of translucent sheet material mounted on the spacer frame between the glass along one of its sides and filling the lower part of the height of the glass in the window opening. A sealed cavity filled with gas.Such a glass is closest to the invention to the technical essence and the achieved result.The disadvantage of this design is the low efficiency of thermal insulation due to the low height of the screen and the impossibility of reconstruction of existing double-glazed Windows.The technical result from the use of is increasing thermal resistance of window units with single, paired and separately-coupled covers with double and triple glazing.This technical result is achieved due to the fact that between the glasses of the window block, forming a vertical air gap, the screen of translucent sheet material ustanavlivaetsya from the condition of conservation of the normalized SNiP values of the coefficient of natural illumination at the settlement points of the premises by the formula

The cover 2 has a screen 3 of the translucent sheet material filling the lower part of the height of the air gap. The screen is attached to the binding point in the air gap fixture or by the spacer frame.Increasing thermal resistance of a window screen is determined by the formula:
< / BR>where RRPROSin(2)the above heat resistance of the translucent part of the window without a screen;

To the proportionality coefficient depending on the material of the screen, the width of the air gap, the binding type.When performing a screen from a sheet of window glass with a height of 0.6 of the height of the window unit with double glazing and double aspect heat resistance is increased by 22% while reducing the transmittance of 3% when running the screen in the form of a film from triacetylcellulose o= 0,94 height of 0.7 of the height of the window by 25% while reducing light transmission to 2% when the execution screen of the shrink filmo= 0,68, o= 0,68 0.5 of the height of the window by 30.5% while reducing the transmittance of 4%
The use of window unit with a screen significantly reduces the intensity of convective and radiant heat transfer and increases thermal resistance of the translucent fence virtually reducing its lighting characteristics. Window with high heat-shielding properties of the containing window unit with single, paired or separately-coupled pereplavlenny in its lower part, characterized in that the screen is mounted to the cover, and the value of the lower part of the air gap of the window opening, in which is placed a screen is determined from the condition of conservation of the normalized values of the coefficient of natural illumination in the reference points of the premises by the formula
