IsoVent DOUBLE Hung window
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.
Common features of IsoVent© windows
IsoVent window section
  • An inclined and welded sill, typical of Fenplast windows, ensuring
    easy cleaning as well as remarkable waterproof performance.
  • A stainless steel coil counterweight system to ensure easy sliding
    of the sashes. A simple and proven system.

  • Inside glazing stop for increased security and practicality in case
    of glass replacement.

  • A handle that is especially designed and punched for easy and
    safe handling.

  • Two ventilation locks located on the frame (single hung) or on the
    upper sash (double hung), ensuring ventilation of the window
    while restraining access from outside.

  • Several parts in moulded PVC to improve efficiency and
    esthetics.

  • May be ordered with a 5 ¾” frame for a non-assembled window,
    or you can simply use the inside and outside mouldings unique to
    the Iso© series..
IsoVent window lock
Profiled and esthetic locks arranged so that it is easy to see if the cam is in an opened or closed position, even from a certain distance from the window. In addition, a symbol clearly shows the position of the cam. 
IsoVent window mechanism
Easy to operate tilt latches allow the sashes to tilt inwards for cleaning that is surprisingly easy.
