Abstract:
1. A casing for an opening in a building with enhanced thermal insulation capacity, comprising: a first tubular section bar made of metallic material, suitable for being fixed to a perimetrical wall which delimits said opening, a second tubular section bar made of metallic material, which cooperates with said first tubular section bar in order to close said opening and supports one or more front panels of an interface between an outer environment and an inner environment of said building, one or more covering elements, placed firmly and externally close to an outer portion of at least one of said tubular section bars, and one or more shaped bodies made of insulating material coupled with an inner portion of at least one of said tubular section bars, wherein at least one of said tubular first section bar and said second tubular section bar presents one or more through openings which create within at least one of said tubular section bars a continuous flow of circulating air which, due to a temperature difference between said inner environment and said outer environment, forms a natural thermal barrier in any season, first sealing means interposed between said first tubular section bar and said second tubular section bar, at least one punched spacer interposed between said outer portion of at least one of said tubular section bars and at least one of said covering elements, thus creating an interstitial air zone communicating with the outer environment, forced ventilation means, suitable to create an air recirculation between said inner environment and said outer environment, placed inside at least one of said tubular section bars and communicating by means of said through openings with a central compartment defined between said tubular section bars and by means of a through slit, made in said outer portion of at least one of said tubular section bars, with said interstitial air zone defined between said outer portion of at least one of said tubular section bars and at least one of said covering elements, and at least one surface finishing element, coupled with the inner and outer portions of said second tubular section bar, said at least one surface finishing element having one or more through aeration holes.
