Louver Free Area Calculator

Are you wondering how to calculate the free area of a louver for your building’s ventilation system? Look no further! Our Louver Free Area Calculator is a handy tool that will help you determine the free area of your louvers with ease. Read on to learn more about louvers, their importance in ventilation systems, and how our calculator can assist you in achieving optimal airflow.

What are Louvers?

Louvers are slatted devices installed in buildings to allow for ventilation while keeping out rain and direct sunlight. They are commonly found on rooftops, walls, and windows, and play a crucial role in maintaining indoor air quality and temperature control. Louvers come in various shapes and sizes, and their effectiveness largely depends on their free area – the open space between the slats that allows for airflow.

The Importance of Louver Free Area

The free area of a louver is essential for determining the amount of air that can pass through it. A louver with a larger free area will allow for more airflow, leading to better ventilation and improved indoor air quality. In contrast, a louver with a smaller free area may restrict airflow and hinder the effectiveness of the ventilation system.

How to Calculate Louver Free Area

Calculating the free area of a louver can be a complex task, as it involves measuring the total area of the louver and subtracting the area occupied by the slats. Our Louver Free Area Calculator simplifies this process by providing a straightforward way to input the dimensions of your louver and instantly calculate its free area.
