Custom aluminum window screens are the best screen mesh choice for areas that have problem with insects such as grasshoppers and mice that eat fabric type material such as fiberglass screening mesh. Aluminum window screen will outlast fiberglass screen mesh in areas where it is left undisturbed. They are rust and corrosion resistant.
The ideal window application for an aluminum screen is a low traffic window that will not be disturbed. It might be ideal for window wells. In most low traffic applications, an aluminum window screen will last on average 30 years. Although, aluminum screening mesh is a metal, it is very delicate. Every time something pushes against the aluminum mesh, it will leave a visible mark in the mesh or even a dent.
