All Prowler Proof Diamond design security screens come with a high quality fibreglass insect screen. But you can take it even further. Aluminium or stainless steel insect screens offer extra strength as well as protection from bushfire. With 18 x 30 strands per inch, a micro fibreglass insect screen will keep out even the smallest insects. And our pet safe polyester mesh is an economical solution if your pet likes to test the strength of the mesh with its claws. With Prowler Proof you can choose your own level of protection.
