If the window is left open, a lot of rain will hit the top of the sash and splash into the house, even with no wind. A good roof overhang can help a lot. In very windy weather, the wind scoop can turn into a sail and get whipped around by the wind, making a racket and potentially damaging the window. The hardware can cause trouble over time, especially with large, heavy casements. The gears that open and close the window when you operate the handle can strip. The linkage that connects the locking lever to the window locks can break. I’ve seen this happen more than a few times. The opening levers are generally easy to replace, but the locking linkage requires removing the casings to get at the guts of the window. Finally, installing a conventional window air conditioner, or a portable unit with a hose, is difficult. Typically, you’ll need to fabricate an insert to adapt the opening to the air-conditioner or hose – not a simple task.

Pros of Double-Hungs
Easy to operate, reasonably tight (with modern, high-quality window), easy to install a portable air-conditioner. With an insert, can do a pretty good imitation of true divided lites, common on older traditional windows. Tend to stay fairly dry if left open in a moderate rainstorm. Many offer easy-to-clean tilt-in sash that allow easy access to exterior surfaces.

Cons of Double-Hung Windows
Half the ventilation capacity of a casement. The meeting rail obstructs views.
Over time, the sash cords and vinyl jamb liners can deteriorate and the movable sash may not stay in the raised position. The sash cords are tensioned and can be tricky to replace.

Vinyl vs. Vinyl-Clad
Solid vinyl windows have come a long way since their introduction in the 1979s. They were originally used only for replacement windows, but were gradually accepted in the new home market. There is a wide range in quality from “builder-grade” windows to premium products. The best ones are reinforced at all their stress points so maintain good dimensional stability.

A casement is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows are often held open using a casement stay. Windows hinged at the top are referred to as awning windows, and ones hinged at the bottom are called hoppers.

Casement windows, including awning and hopper types, "generally have lower air leakage rates than sliding windows because the sash closes by pressing against the frame.

Casement windows are also excellent for natural ventilation strategies, especially in hot climates. Casements allow more control of ventilation than flush-opening windows. They can be hinged to open outward and angled in order to direct breezes into the building.
