Pivot windows are a suitable replacement window choice if you wish to include maximum ventilation in a room.
The pivot window sash is secured to the window frame by a pivot mechanism, located mid-way along opposing window sashes which attach the window sash to the frame. The window can then swing inwards either horizontally or vertically, depending on the location of the pivot mechanisms. This leaves the sash suspended in the middle of the frame, held by the opposing pivots.
The pivot window is a good choice for attics, cupolas, lofts and other challenging or unique spaces. In addition, you could choose pivot windows for pool rooms, porch areas, conservatories and staircases.
