Upon building your home you may come up with the question, do I install single-hung or double-hung windows? Single-hung windows have one stationary sash and one moveable sash, while double-hung windows have two moveable sashes, one at the top and one at the bottom. These windows can be opened from both the top and the bottom sashes. This feature provides better ventilation due to the ability to move both top and bottom parts of the window. Additionally, this feature gives owners more versatility and even makes the cleaning process easier because window motion isn’t as limited. Double-hung windows may be more expensive, but the advantages offered outweigh the extra expense.
