Alitherm 700 (Parallel) is an innovative solution for enhanced natural ventilation. The system allows for a balanced, effective airflow whilst maintaining security and safety.  Alitherm Parallel is ideal for insertion into curtain wall facades in both low and high rise commercial buildings. The system is suitable for use as either replacement windows in existing buildings, or for installation into new builds. Alitherm Parallel incorporates internally beaded vents suitable for either cockspur or shoot-bolt locking. The system is also suitable for use with chain-operators, operated either individually or as part of an integrated automated solution for building climate control.
