FRAME WITH IMPROVED HEAT-INSULATING PROPERTIES FOR OPENINGS OF BUILDINGS Russian patent published in 2015 - IPC E06B1/16 E06B3/263 

FIELD: construction.

SUBSTANCE: invention relates to frames with improved heat-insulating properties for openings of buildings. A frame with improved heat-insulating properties for openings of buildings includes the first tubular element that is attached to a perimetric wall restricting the opening and the second tubular shaped element interacting with the first shaped element, thus providing tight closing of the opening and acting a role of a support for one or more front panels of the boundary limit between outdoor environment and indoor environment of the building room. At least one of the first shaped element and the second shaped element includes a row of through holes creating at least in one of the tubular shaped elements a continuous flow of circulating air, which due to drop of temperatures between outdoor and indoor environment creates a natural heat barrier during any season of the year.

EFFECT: development of a frame with improved heat-insulating properties.
