If your needs require high thermal performance, the solution is FEAL windows and doors with an interrupted thermal bridge.
The thermally broken bridge is a continuous barrier between the inner and outer aluminum profile. The material of the broken bridge can be PA66 GP25, PA66 GP25 Low Lambda and ABS. The broken thermal bridge creates energy loss, which reduces the passage of heat to the outside during the winter months, and to the inside during the summer months, which creates a pleasant stay inside the building throughout the year.
