Which is better: casement or sliding windows?

Here are some factors to consider when choosing between casement and sliding windows:

Climate: Casement windows are the best option in a hot climate as they offer better ventilation. Sliding windows may be a better choice as they are easier to seal tightly against drafts in a cold climate.

Security: Casement windows are generally considered to be more secure than sliding windows, as they have multiple locking points.

Maintenance: Casement windows require more maintenance than sliding windows, as the moving parts need to be cleaned and lubricated regularly.
