Gorell offers several types of projecting windows:
Casement windows are side-hinged to swing out vertically, right or left.
Awning windows are top-hinged to swing out horizontally from the bottom.
Hopper windows are inverted versions of awnings that are used typically in basements. They're bottom-hinged to swing in horizontally from the top. They feature a different design and hardware from standard awning windows.
Gorell casement and awning windows feature compression weather stripping and locking mechanisms that pull the sash tightly into the framefor an airtight seal you'll appreciate when you get your utility bills!
