Security Window Screens


To improve the level of security around the home, many people choose to install security window screens. The reality is, windows can be an easy target for intruders as often the only barrier is a flimsy fly screen and a breakable window. It’s not enough of a deterrent for intruders, you need to protect your home with a product that has proven strength.

Just like our security doors, security window screens from KNA will provide a premium level of strength and safety, not only meeting the Australian Security Standards but exceeding them.

Installing window security screens won’t shut you off from the outside world. In fact, you’ll find that you’ll leave your windows open more and let in more sun, more fresh air more often.

Unfortunately, you can’t control external factors. If someone decides they want to target your home and break in, all you can do it protect yourself as best as possible. Securing your windows with KNA Security screens is the ultimate deterrent and will keep you safe in your home without making you feel like you’re trapped in a fortress. KNA is the safe and stylish option for security screen windows throughout Perth.

Security Window Screens


One of the main concerns people have about door and security window screens is how they will look. Just as the technology behind security screens has advanced, so too has the designs and styling.

There are also over a 100 frame colours to choose from, so matching your current colour scheme is no issue. If you have a home that has a unique look and you can’t find a window security screen to match it, remember you can choose to have your screens custom made in our quality-controlled Perth factory.
