A Casement window provides the much-required energy efficiency in a room and is regarded as the second most energy-efficient window. Fixed-pane windows remain the most energy-efficient window on the market. The sash prevents air leakage and entry by pressing against the frame when closed, creating an airtight seal. This gives the homeowner a comfortable temperature in their home throughout the year, even in the coldest of winters. This allows the homeowner to reduce their reliance upon their central heating, saving money on energy bills and reducing their property's carbon footprint.

The types of casement windows include:
