Louver Aesthetics - Form, Shape, Color

Learn how to turn boring, square louvers into works of art.

Louvers have many different uses. They can allow air to pass in or out of a building or protect its interior spaces from rain and severe weather conditions.

Louvers can also enhance a building’s aesthetic.

For a detailed explanation of louvers and their uses, consider taking our self-paced course on louvers: "An Introduction to Louver Selection." Visit the MCDLG Campus portal for more information.Visit AEC Daily to see MCDLG Online Courses


Architectural Louvers

Architectural louvers are commonly referred to as thin line louvers.Architectural louvers – also known as thin line louvers – are designed to accent a building’s face. Their light weight and thin design make it easy to place architectural louvers on any surface, using special vertical blade supports. This creates a continuous blade look that accents the lines of a structure.

Architectural louvers are only meant to enhance aesthetics, and don’t serve the typical functions of a louver. For the purposes of air movement (intake and exhaust), these louvers are considered non-functional. However, architectural louvers can be connected to intake or exhaust louvers to extend the louver past the opening.

But architectural louvers aren’t the only way to make your building look good.

 

Hidden and Recessed Mullions

For many standard louvers, you can choose a recessed or hidden mullion option. These options can remove the visible divisions between louvers, creating the same continuous lines for louvers linked together.

A recessed mullion has a support member hidden behind the conjoined blades. This style still shows a small bit of mullion, which may be noticeable as a viewer gets closer to the louver. A hidden mullion will have supporting members behind the conjoined blades. Hidden mullions are entirely hidden behind the blades of the louver, but this design may affect the louver's wind load capabilities. The blade supports will not have the same structural integrity of a standard frame louver, and thus will be affected by high winds.

Consider where your louver will go and what will be required of that louver before making your choice. And if you have any questions, you can always consult the manufacturer.

With recessed and hidden mullions, a series of intake louvers can look like a single unit. And even better, these changes won’t affect the louver’s air performance.

Custom shapes

Louvers can be built into a custom shape to fit any design.Many louvers are also available in custom shapes. Louvers can be more than just squares and rectangles. A custom shape louver can be any shape you want. Need an arch shape? Or a circle? How about a nice triangle for your entry way?

With custom shapes, you can make your louvers fit your design; not the other way around.

AMCA-rated louvers will lose their rating when built into a custom shape.

 

In general, wind driven rain and hurricane louvers are not available with these options. Because of their specific purpose – to withstand heavy storm conditions – their design cannot be changed. But that doesn’t mean you’re stuck forever with a bare-metal severe weather louver. There are other ways to spruce up a louver.

 

Finishes and Color Options

Louvers can come in a variety of colors, or can be color matched to fit the project's aesthetic.Louvers can also come in different colors, thanks to powder coatings. These finishes are available in a variety of colors and finish types, from standard powder coat to the long-lasting Duranar 500 and Duranar XL coats. You can also choose an anodized coating for your aluminum louvers, giving them a smooth metallic sheen.

If you don’t see a color you want, you can also request a color match to achieve that perfect shade for your building’s accents.

Your building’s aesthetic is important. Your louvers don’t have to be square, metallic eye sores on your building. You have a variety of options available. Make them work with your design!

Louver aesthetic is important. Should the louvers match the project or is it better if they clash? What would you add to your louvers? Tell us in the Comments section. MCDLG wants to know what you think!
