PalmSHIELD Louvers

PalmSHIELD louver is 100% direct visual screening. 

 

As a matter of fact, PalmSHIELD louvers standard design uses a ½” overlap based on direct visual screening.  Direct visual screening is the standard measure for determining the percentage of visibility.  It is exactly as it is described.  Based on looking head on at a perfect horizontal plane to a louver that is installed plumb, can you see through the louvers?  Any visibility at this vantage point is a percentage of visibility.    

 

PalmSHIELD’s standard design uses a ½” overlap of louvers.  This guarantees 100% direct visual screening under any circumstances.  We are happy to modify our louvers to provide a lesser percentage of direct visual screening for our customers which would require we space the louvers farther apart.

 

Our 100%  direct visual screening is directly related to our percentage of openness.  The percentage of openness is the actual openness between the louvers over a specific area.  The smallest opening between two louvers is the greatest factor impacting the percentage of openness.  PalmSHIELD louvers typically louver opening based on 100% direct visual screening is 2 ¼”  In other words, with 4” tall louvers spaced 3 ½” on center, the smallest opening is 2 ¼”.   Boiled down, every 3 ½” of travel, there is a 2 ¼” opening.  This ultimately translates into approximately a 64% free area.
