Light weight screen mesh has an open and porous weave that allows for great air flow and more day light.
Heavy stronger screen mesh will conversely be much more restrictive in air flow and light.
So keep it light weight unless screen strength is the bigger concern.

No screen is child proof!
Window and door screens are designed to keep insects and bugs out of your home. Screens will not stop a determined child or your pet from getting through a screen door or keep them from falling out of an open window. Keep young children and your pets away from open doors and windows.
