The HAHN Louvre Windows S9 was developed for optimized, controlled ventilation. It combines good tighntess with attrative architectural effect when insulated glazing is not necessary. Appearance is dominated by overlapping glass louvres.
Use of other fillings such as timber, aluminium or even stone panels will result in interesting appearance with selective light control.
The S9 is certified for use as NSHV (Natural Smoke and Heat Ventilation) device according to EN 12101-2
