Insect Critical Dimensions

and Screen Recommendations


A screens hole size is one of the most important considerations when it comes to selecting an effective insect control solution. While most screens may appear to have consistent hole sizes, microscopic analysis' often reveal irregular hole sizes, shapes and diameters which can limit complete pest exclusion.

All Svensson Econet screens are designed with hole sizes based on measurements of real insects. Thanks to our uniform weaving process, hole sizes are consistent across the entire screen.
