What is a Louver, Where Are They Used, and How Do They Work?

Our eyes are often drawn to the blinds and shutters when it comes to window treatments. But what about louvers?

Louvers are commonly used in architecture to control the flow of air and light. Louvers are used in various applications: from regulating the temperature of a room to controlling the amount of oxygen that gets into an incubator. But what exactly is a louver?

In this article, we’ll discuss what louvers are and how they work. We’ll also cover some of their most common applications so that you can decide whether they’re suitable for your home.

What Is a Louver?

A louver is the part of the HVAC system that allows airflow into the building but blocks the rest of nature from getting in. Louver is a window treatment that allows for light control and ventilation. Louvers can be installed as a standalone window treatment or in combination with other types of window treatments.

What Is The Purpose of Louvers?

Louvers are used to control natural light, temperature, and airflow in a building. Louvers help regulate heat gain or loss by preventing unwanted solar heat gain while allowing fresh air to enter the building. 

Louvers are often installed in restaurants and other public buildings where people might not want to see inside. You can also use them in homes and businesses alike to prevent sunlight from coming in at certain times of day (like early morning or late afternoon) so that it doesn’t get too hot inside those spaces.

Where Are Louvers Used?

Louvers can be found anywhere there’s an HVAC system in place. Louvers are most commonly found on windows or doors, which means that they’re responsible for keeping cool air flowing into your home during summer and warm air flowing out during winter months.

Louvers are used in a lot of different places, including:

  • Schools
  • Residential homes
  • Hospitals and other medical facilities
  • Offices and other commercial buildings
  • Restaurants and other food-related businesses

How Do Louvers Work

Louvers are usually slanted so that the air can flow in a straight line through the opening. The louver’s construction helps create an even breeze across the whole area. Slanted vents can be made of various materials, including wood, metal, and plastic. Louvers are often combined with other cooling equipment, such as evaporative cooling pads or fans.

Different Types of Louvers

Different Types of Louvers

1. Stationary Louvers

These are the most common type of industrial louver. Stationary louvers may be fixed in place or mounted on tracks. They don’t have any moving parts; instead, they’re made of metal or plastic and use a curved design to control airflow.

Stationary louvers are affixed to an object as part of its design as sunscreens or shading devices for windows and doors.

2. Adjustable Louvers

Louvers with movable parts allow you to alter their position depending on what kind of airflow you want to achieve in a space. Adjustable louvers have hinges that allow them to be opened or closed manually; this makes it easy for users to regulate temperature levels when necessary.

3. Combination Louvers

Combination louvers have both stationary and adjustable features in one product. Combination louvers allow you to adjust the amount of airflow coming through your system while still controlling how much heat gets out, making them ideal for heating and cooling applications alike.

4. Air Measuring Louvers

Air measuring louvers have closely-spaced vertical blades that prevent water from entering the structure. Louvers with narrow vertical blades are used primarily in industrial buildings and other establishments where there is a need for ventilation and protection against rain or snow.

By Application

Louvers come in a variety of shapes, sizes, and colors. The different types of louvers are determined by their application and their specific qualities and characteristics.

Function

Industrial louvers are designed to withstand extreme weather conditions, including rain, wind, and snow. Industrial louvers are usually made of metal or wood and are installed on top of a building’s exterior wall.

Application

Industrial louvers are often used in warehouses and factories where there’s a lot of heat generated around the area.

Louvers can also be used in office buildings where there’s less chance of flooding from above ground level due to runoff from nearby rivers or streams nearby such as those located near rivers or streams.

2. Commercial Louvers

Function

Commercial louvers are generally smaller than industrial louvers but still large enough to provide adequate ventilation without being obstructed by furniture or other objects inside a room.

Application

Designed for use in high-traffic areas such as grocery stores and airports, commercial louvers are often made from metal or plastic to be cleaned quickly and last longer.

3. Architectural Louvers

Function

Architectural louvers’ primary purpose is to provide shade and privacy, allow natural light to enter a room or building, and create an aesthetically pleasing exterior wall construction.

Application

The louvers can be placed over doors, windows, or other openings in structures or facades. Architectural louvers are usually installed outside the building so that they do not interfere with interior space or function.

What Is a Louver Vent?

A louver vent helps you control airflow in your home. It can help you reduce energy costs and improve your home’s indoor air quality. Louvers are usually installed on the outside walls of your home, and they let in fresh air while keeping out warm or cold air, depending on which way they’re opened.

Louver vents come in many different types and sizes, but all work on the same principle: they direct air where you want it to go based on how much pressure is exerted against them. 

That’s it for our blog about louvers. Hopefully, this blog has provided you with helpful insights about louvers. As our blog post demonstrated, louvers can serve a variety of functions and can be found in various locations, from rooftops and attics to windows and gates. To match your needs, you can control their size and shape, tilt angle, aperture size, and material type.
