Casing For Openings Of Buildings With Enhanced Thermal Insulation Capacity

Abstract

A casing (1; 50) for openings of buildings with enhanced thermal insulation capacity comprising a first tubular section (2; 51) which is fixed to the perimetrical wall delimiting the opening, and a second tubular section bar (3; 52), cooperating with the first section bar (2; 51) in order to hermetically close the opening and capable of supporting one or more front panels (4, 5) of interface between the inner environment and the outer environment of the building. At least one of the first section bar (2; 51) and the second section bar (3; 52) presents a plurality of through openings (6; 53) which create within at least one of the tubular section bars (2, 3; 51, 52) a continuous flow of circulating air which, due to the temperature difference between the inner environment and the outer environment, forms a natural thermal barrier in any astronomical season.

Description

technical field [0001] The present invention forms part of the field of construction and more particularly relates to a frame with improved thermal insulation properties for openings belonging to any building, such as windows, doors, facades and the like. [0002] More specifically, the invention relates to frames of the so-called "closed joint" type with improved thermal insulation properties, provided with double gaskets, one external and one internal, in the frame-like profile of the frame. [0003] Said frame comprises a welded or open tubular profile, with opposite attachment frames and one or more decorative elements. Background technique [0004] As is known, frames or frames for closing openings in buildings have always existed on the market in the field related to this document, capable of maintaining in a more or less efficient manner within the environment defined by the perimeter walls in which the frame is installed. of thermal insulation. [0005] Indeed, one...

Problems solved by technology

[0014] On the other hand, the aforementioned thermal insulation frames have the recognized disadvantage of being subject to the so-called "bimetallic effect": the outer and inner tubular profiles, which are at different temperatures from each other, inevitably suffer from a non-homogeneous thermal expansion which causes Dangerous deformation of the profile itself, especially if it is made of aluminum, since, as is known, this material is a good conductor of heat

[0020] But in the case of conventional thermal insulation frames, it is not possible to perform such a polishing process, since a large pressure is provided on the metal tubular profile, which would then seriously jeopardize the safety of the connection between the insulating material element and the tubular profile
