What is a Grille in an HVAC system?
A grille is a metal or plastic panel with a series of parallel slits that helps to regulate and direct airflow in a ventilated space.
What are grilles used for?
Grilles are commonly used in heating, ventilation, and air conditioning (HVAC) systems to protect against the passage of large objects and help to distribute airflow evenly. In some cases, grilles may also be used for decorative purposes.
Are there different types of the grille in HVAC?

- surface-mounted,
- recessed,
- floor,
- and ceiling grilles.
Each type has its own advantages and disadvantages that should be considered before installation.
What materials are grilles made from?
Grilles are typically made from metal or plastic. Metal grilles are more durable and often used in commercial applications, while plastic grilles are lightweight and easier to install.
How are grilles installed?
Grilles can be installed in various ways, depending on the type of grille and the application.
- Surface-mounted grilles are attached directly to the wall or ceiling, while recessed grilles are mounted flush with the surface.

What’s the difference between a grille and a diffuser?
A diffuser is a device used to control and disperse airflow. Unlike grilles, diffusers do not have openings and instead rely on vanes or louvers to direct airflow. Grilles are usually more aesthetically pleasing than diffusers and are often used in public spaces such as offices and hotels.
