Though both double-hung windows and casement windows are the best in their way, the pick here would be casement windows. There are a few reasons why casement windows are a more ideal option. Starting with the design, casement windows are aesthetically designed and easy to operate. They provide excellent ventilation, energy efficiency, sound insulation, and protection against rainwater seepage, to name a few other reasons. Adding to this, casement windows are available in single and double-pane options, making them a sturdier choice for home windows. However, with advancements, you can also find double-hung casement windows for the home that offer even better benefits and features.
