Consider Roof Windows for Manual Operation
Due to the construction of the walls and roof, some rooms aren't suited to regular windows. Enter roof windows, a special category that can light from above, open for fresh air, and even count as a point of egress! They are similar to skylights, but you'll find different types that open from the top, side, or by pivoting at the midpoint on the frame. Be sure to consider roof windows, if you have the structure for them!
