Awning windows are a favorite of architects and designers trying to achieve a wall of large glass sheets with a minimum frame and where fresh air venting is desired or required. A classically contemporary setup is the large fixed glass panel set above an awning window that is kept low in the wall. This setup allows for expansive, unobstructed views to the outside while making sure that it’s possible to get fresh air into the room.
Cost. Awning windows will be much the same price point as casement windows. Depending on size, features and materials, expect to pay about $300 to $500 for an awning window.
A hopper window is much like an awning window except that the bottom of the sash is hinged to the frame so the top tilts in. While the traditional hopper would only function this way, titling in from the top, today most hopper windows are made as tilt-and-turn windows.
This window will either tilt in at the top (being hinged at the bottom) or swing in (hinged along one side). A lever is used to engage or disengage the hinging system so that either the window tilts in at the top, as a hopper, or swings in from the side, as an inswing casement.
These windows are an excellent choice where there’s a desire for an easy-to-clean window that can meet building code requirements and just be open a slight bit when some fresh air is desired. Some extra care will have to be taken when designing a room due to the swing feature. Furniture, lamps, etc. will all have to be placed so the windows can be easily opened and closed.
Cost. It wasn’t long ago that most tilt-and-turn windows were imported, as these windows have long been common in continental Europe. In the past few years, many domestic manufacturers have been making these windows. Just keep in mind that the extra mechanical pieces and dual operation will typically make these the priciest of made-to-order windows.
