Theory Behind The Power Of The Net:

1) The most basic benefit of the net is its ability to strap down and stabilize a structure:

Take this unprotected structure. It is vulnerable to many elements of nature:

And here are some of the many ways the CAT-5 Hurricane Netting System can help:

Ground installation can be to soil or concrete. There are many installation possibilities!

2) Add to that the wind reduction benefits of the engineered fabric:

Basic pressure is the square of the velocity. the larger the wind speed, the exponentially larger the wind pressure. (qh=0.00256KhKhtKdIV^2) Ref:ASCE7 eqn 6-15

Damage to structures occur due to 'mulipliers' to this basic wind pressure formula (PRESSURE=qh((GCp)-(Gcpi)) ASCE7 eqn 6-23. Formulas from ASCE7 define how pressures are increased due to turbulent, vortex-like forces:

Excerpt from ASCE7-2002, Chapter 6, Gcp pressure multipliers, used to determine PRESSURE

Without the protection of the CAT-5 Hurricane Net, there are many vulnerable areas of a structure that are affected by these sensitive areas:

Vulnerable 'turbulent prone areas' are protected by the net as the wind blows in and out of the the net, completely disrupting any possiblity for turbulent activity to a structure. Consider these 2 scenarios to better illustrate the reducing effect of the CAT-5 Net:

The below wind reduction chart is only part of the picture. When you decrease the velocity, you exponentially decrease the pressure, AND you disrupt any of the mulipliers, resulting in an dramatic reduction of wind pressure as illustrated above. Combined with its strapping and stabilizing abilities, a properly designed and installed CAT-5 Hurricane Netting System is the engineered, logical, and undisputable choice for your storm protection needs.
