Doors, windows or the like for buildings having means for increasing their insulation

摘要

The woodwork has a right dihedral shaped frame rabbet (13) equipped with a L or square shaped integrated thermal insulation section (15), which covers a part of lateral and bottom surfaces (13a, 13b) of the rabbet. Coefficient of thermal conductivity of the section is less than the coefficient of thermal conductivity of the material of structured sections (10, 11) of a frame (2). The insulation section has a structure element (16) extended parallel to the structured sections, where the element is made of thermoplastic material.
