Thermal bridge rupturing device for fixed windows casement, has reinforcement unit made of steel having elasticity and expansion coefficients different from aluminum used to fabricate sections of inner and outer bodies of device

摘要

The device has a connection unit (4) for breaking a thermal bridge between inner and outer bodies (2, 3). A reinforcement unit (7) is connected to the outer or inner body by a rigid connection. The reinforcement unit is made up of steel having an elasticity coefficient and an expansion coefficient different from that of aluminum used to fabricate sections (5, 6) of inner and outer bodies of the device.
