What type of windows are usually found in older warehouse or commercial buildings?

Projected windows are a common feature in older warehouse or commercial buildings. These windows are designed to open outward and typically have a pivot point at the top or bottom, which allows for easy ventilation while still providing security and protection against the elements. Their design facilitates airflow into large spaces, which was particularly beneficial in warehouses and commercial settings before modern HVAC systems became widespread.

In older construction, projected windows were often used for their ability to provide natural light and ventilation, making them ideal for large manufacturing or storage areas. Their functionality and aesthetic fit with the architectural style of the time contribute to their prevalence in older structures.

In contrast, other types of windows like awning, horizontal sliding, and casement have different operational mechanisms or design purposes, making them less common in such older buildings. For instance, awning windows provide ventilation but are generally found in residential settings or places where water drainage is crucial, while horizontal sliding windows are often utilized in contemporary designs for convenience and ease of access. Similarly, casement windows are typically used in more modern residential designs due to their efficient sealing properties and ease of operation.
