Window Security Screens – Protect Your Home from Intruders

Window Security Screens

When most people think of security doors and screens, they tend to think of doors before windows. However, windows are just as essential and are often an easier target for intruders. After all, the only barrier is a flimsy fly screen and breakable window.

Although window security screens are an excellent deterrent for would-be intruders, it’s also vital that they offer an exceptional level of strength and safety should an intruder try to break in.

Long gone are the days when window security screens are an eyesore. These days, they come in various styles, colours and materials to suit most homes seamlessly. They even allow you to open your windows more often and let in the sun and fresh air, with peace of mind your home is still secure.

Security Windows

“I have just used KNA again for my front flyscreen (different house). Amazing service, friendly admin and technicians. Reasonable pricing and quick turn around (considering doors are made to order). I will always use KNA – top quality and highly recommend. Thank you to the technician who came out, he was lovely and very helpful with a good ethic.”

“To the point, fair price for the privacy door and the person who installed the door did a fast and clean job. Very happy with the service. Also good communication and speaking with a real person when you ring up the office. KNA was highly recommended by the locals. I can see why.”
Grant Bartle
