DOUBLE Hung window

This window, with two movable sashes, ensures excellent ventilation. The exceptional results obtained in the various waterproofing tests show this window has a distinct advantage. You may choose from a full size screen or a halfscreen (as illustrated).
IsoVent SINGLE Hung window
Single Hung window
Still the same type of window but built so that only the bottom part of the sash is movable. This window, which is more economical without making any compromise in performance, surprises by its integrated aspect. The horizontal mullion, which is simple and straightforward, is mechanically assembled to ensure structural rigidity.
