Hopper Windows

Typically utilized in basement applications, Mercury Excelum Hopper windows are like a casement window that is hinged at the bottom and tilts open at the top, instead of the side.

Hopper windows help prevent leaves, dust, and trash that might be blown along the ground from blowing right into your basement. Another benefit of hoppers, like casement windows, the entire window area can be opened.
