nom + 0” Calculating Open Area of Modular Synthetic Screen Media


Synthetic screen media manufacturers of standard border screen panels often claim their screen media has “the highest open area in the industry”. Since it’s obviously impossible for more than one company to make that claim, make sure your supplier is using the formula below to ensure that “true open area” is being evaluated.


Make sure the calculation is based on the ENTIRE surface area of the screen panel, not just the area where the holes are.


37,125mm2 (165 holes x 225mm2 / hole)


92,903mm2 (304.8mm (12”) x 304.8mm) Yields 39.96% open area (165 holes)


Once the open area of each screen panel is calculated based on the entire screen panel surface, it becomes obvious that Polydeck’s Maxi screen panel design has more open area than competitive designs of identical dimensions.


Or, if you prefer, when comparing panels with the same size opening, a simpler, yet equally effective measure is to COUNT THE HOLES!
