The versatility of the locking mechanism used in the ST70 system allows the designers to incorporate extra-large sashes into the fenestration or facade.
The ST70 parallel vent provides efficient natural ventilation to your building. The rate of air exchange can be controlled through its variable opening widths.
Providing an elegant visual effect, this system does not take up any room inside.
The ST70 parallel vent with its glazing variation of 28-42 mm provides suitable panel infill room required to suit your projects’ thermal and acoustic requirements.
