Louver Aesthetics - Design Options for Architectural Louvers

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.

 

Architectural Louvers

Thin line louversArchitectural 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.

Looking for more? Are you more focused on the louver's function over its form? Read our article on the full range of options available, on the MCDLG Newsstand: Options for Louvers.

 

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.

Examples of recessed mullion and hidden mullionAs seen on the left side, the recessed mullion will still be visible behind the blade profile.  The hidden mullion on the right will use supports behind the blades to eliminate the mullion from the blade profile.

 

Custom shapes

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

Louver with a custom arch shape

 

There is one important thing to consider when creating a custom shape louver. Changes in louver shape will alter the louver's performance. AMCA's standardized test methods only account for square or rectangular louvers. The data and ratings from these tests will not apply to custom shape versions.

For instance, if you have a louver with an AMCA's rating seal for air performance, this seal will not apply to the louver if it is built in any shape square or rectangular.

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

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!
