Periodically Shutter Medic ® receives questions concerning louvers that have a raised pronounced grain surface.
Some manufacturers in an effort to distinguish themselves from competitors offer this type of louver to customers. This has become less common in the past decade due to lack of demand, and the requirement of an added step involved with the fabrication process of this type of louver.
In order to attain the raised grain texture, the louvers are passed through a drum sander that contains a rotating wire brush. This wire brush removes the softer wood fibers between the grain, producing the raised grain surface as depicted in the photos.
Shutter Medic® offers Brushed Raised Grain Louvers in both 2 1/2 and 3 1/2 Elliptical profiles which are 7/16 inch thick. Thickness is measured at pin location.
