ABSTRACT:
An insect screen of increased invisibility can be created by using small wire diameter elements and/or increasing the mesh density of the screen. The combination of small wire diameter and increased mesh density provide a screen with a higher Dalquist Rating that becomes invisible at closer distances. A “sweet spot” exists at which a screen with a combination high mesh density and small wire diameter is less visible, while still providing the strength, durability, and quality desired. Further, screens with properties in proximity to this sweet spot also provide a marked increase in invisibility.
