Jalousieglas

Detailed Product Dscription Louver glass that overlap one another form the panes of a jalousie window. Operated with a crank or turu-screw,the louver glass tilt to open, permitting air flow. Besides the fact that they dont obstruct the view, their biggest advantage is they allow ventilation. A wall of jalousie windows can be opened to let breezes flow, making the indoors feel like outside. This advantage however is also their great disadvantagethey allow ventilation so well they are almost impossible to steal. When closed, each glass louver rests against the one below it, rarely if ever making an air tight seal, and the hinges along the sides are almost impossible to seal without covering the entire window.
