The Right Windows Bring the Best Out of PTAC Units

Packaged Terminal Air Conditioners, commonly referred to as PTAC units, are widely used in commercial buildings due to their convenience and cost-effectiveness. These units provide both heating and cooling capabilities and are commonly found in hotels, hospitals, senior residential facilities, apartments, and even residential add-ons like sunrooms.

To maximize the benefits of PTAC units, it is crucial to choose the right windows that complement their functionality. In this guide, we will explore the advantages of using louvered windows in conjunction with PTAC units, as well as provide insights into selecting the appropriate louvered windows for your needs.

What is a Louver Window?

Louvered windows, also known as jalousie windows, are windows that consist of multiple horizontal slats, or louvers, that can be tilted open or closed to control the amount of airflow and ventilation. These windows are typically made of glass, aluminum, or uPVC (unplasticized polyvinyl chloride), and they offer various benefits when used in conjunction with PTAC units.

Materials for Louvered Windows

When considering louvered windows for your PTAC unit, it is essential to choose the right material that suits your needs. Here is a comparison table of the different materials commonly used for louvered windows:

Fixed vs Adjustable Louvers

When selecting louvered windows for your PTAC unit, you have the option to choose between fixed louvers or adjustable louvers. Understanding the difference between the two will help you determine which type is best suited for your specific requirements.

Fixed Louvers: Fixed louvers are stationary and cannot be adjusted. They provide a constant level of ventilation and are suitable for areas where a consistent airflow is desired. Fixed louvers offer simplicity and ease of installation, making them a cost-effective option.

Adjustable Louvers: Adjustable louvers, on the other hand, can be tilted open or closed to control the airflow and ventilation. This allows for greater flexibility in adjusting the amount of air entering the room. Adjustable louvers are ideal for areas where precise control over ventilation is required, such as in rooms with varying occupancy or changing weather conditions.

Benefits of Louvred Windows for PTAC Units

Using louvered windows in conjunction with PTAC units offers numerous benefits, enhancing the overall performance and efficiency of your cooling and heating system.

Ventilation / Airflow

One of the primary advantages of louvered windows is the enhanced ventilation and airflow they provide. The adjustable louvers allow you to control the direction and amount of air entering the room, ensuring proper air circulation and reducing the reliance on the PTAC unit alone.

By promoting natural ventilation, louvered windows can help improve indoor air quality and create a more comfortable environment.

Installation Costs

Louvered windows can be an economical choice when it comes to installation costs. Compared to other types of windows, such as double-hung or casement windows, louvered windows are relatively simple to install. Their design and functionality make them an attractive option for retrofitting existing buildings or incorporating into new construction projects. The ease of installation can result in cost savings, especially when considering a large-scale installation of PTAC units in commercial buildings.


In addition to their functional benefits, louvered windows also offer aesthetic appeal. The horizontal slats provide a unique visual element, adding a modern and contemporary touch to any space. Louvered windows can complement various architectural styles and interior designs, making them a versatile choice for both residential and commercial applications.

Adjustability / Fixed Ventilation

The adjustability of louvered windows allows for precise control over the amount of ventilation and airflow. This feature is particularly useful in rooms where individual preferences or varying weather conditions require flexible ventilation options. The ability to tilt the louvers open or closed provides the opportunity to create a comfortable and customized indoor environment. Alternatively, fixed louvers offer consistent ventilation without the need for adjustments, making them suitable for areas where a constant airflow is desirable.

Additional Considerations

When selecting louvered windows for your PTAC unit, consider the following factors:

Energy Efficiency: Look for windows with high energy efficiency ratings to minimize heat transfer and reduce energy consumption. Low-emissivity (low-e) glass or uPVC frames with thermal breaks can help improve energy efficiency.

Noise Reduction: Louvred windows can provide effective noise reduction, particularly when equipped with soundproofing features. Consider windows with acoustic insulation properties if noise reduction is a priority.

Security: Ensure that the selected louvered windows offer adequate security features, such as multi-point locking systems or laminated glass, to protect your property and provide peace of mind.

Maintenance: Evaluate the maintenance requirements of the louvered windows, considering factors such as cleaning accessibility, durability, and resistance to environmental elements.

Building Codes and Regulations: Familiarize yourself with local building codes and regulations to ensure compliance when installing louvered windows and PTAC units.

By carefully considering these factors and selecting the right louvered windows, you can optimize the performance of your PTAC unit and create a comfortable indoor environment.


Choosing the right windows for your PTAC unit is crucial to maximize its benefits and ensure optimal performance. Louvered windows offer enhanced ventilation, cost-effectiveness, aesthetic appeal, and adjustability, making them an excellent choice for use in conjunction with PTAC units.
