What style of window ( casment vs awning vs double hung vs etc) and screen best minimizes the dust blown in through a partially open window?
In a bathroom with no vent fan, there is currently a small aluminum single hung window, about 16" x 24", which will often be left partially open for ventillation. The sill is about 5 ft from the floor and also from the ground outside. The old aluminum window panel is loose and it only takes a few days for brown dirt to blow in and cover the sill even when the window is closed. What type of window would be the best replacement ? - or is there some kind of cover that could be put on the outside of the window to allow ventilation but minimze dust?
