White Hopper Replacement Window By Zen Windows St. LouisHopper windows are similar to casement windows as both types are hinged at the bottom and tilt open at the top rather than at the side. The only main difference between the two is that the hopper windows open inwards whereas casements open outwards. Because of this, the screen on hopper windows is attached outside.

Hopper windows are commonly ideal for basement and bathroom applications or in any small areas that require lots of ventilation. For ease of operation, hopper windows come with a small lever handle, which is also designed to serve as the units’ locking mechanism.

The most significant benefit of a hopper window is that it offers excellent ventilation given that its window area can be opened up completely. This also allows a hopper window to invite a significant amount of natural light into the room. Also, it prevents dust, dried leaves, and other trash to get right into your home. Plus, its design eliminates any possibilities of someone being hit by its sharp corners whenever you open it.

Largely because of their small dimensions, hopper windows are often used as transom windows, installed above doors or much larger sized windows.
