Joinery for bay e.g. fixed bay, of building, has thermal bridge rupture profile whose body has external surface covered partially by heat insulator covering, where covering and body are formed into monoblock in heat insulator material

摘要

The joinery (1) has structure profiles (4, 5) and a thermal bridge rupture profile (6) associated together by edging profiles (10) and grooves (11). The thermal bridge rupture profile comprises a body (7) made of heat insulating material, where external surface of the body is covered partially by a heat insulator covering (12). The covering and the body are formed into monoblock by another heat insulating material whose heat conductivity coefficient is lower than constitutive material of the body. The covering of a thermal bridge (24) is made of cellular thermoplastic material.
