“Doing the right thing by our clients isn’t rocket science and it is what has built KNA Security Screens Perth to where it is today.”

KNA Security Founder, Wayne Wright

Why install security screens?

Every year in WA, almost 30,000 homes are broken into and surprisingly this is more than 50% more than the national average per capita.

The most popular items stolen include jewellery, laptops and mobile phones. Items that are most precious or hold important personal information.

The days of the flimsy old fly screens are over, they offer no deterrent for would-be criminals. You need to protect your home with the strongest and most reliable security screens on the market.

Security screen doors have also come a long way in terms of decorative appeal. AT KNA Security, we have hundreds of powder coat colours and timber look frames that will not only compliment your home in terms or colour, they will actually add an element of style.

What is KNA Security’s secret weapons on crime?

Whilst most companies have only one residential stainless steel security screen system that passes Australian Standards, we have three.

These include:

Invisi-Gard – This is the absolute premium in security screens and comes backed by a fifteen-year warranty. Using a superior grade stainless steel mesh, we are able to produce a security screen that looks great, is highly secure and corrosion resistant. Invisi-Gard is also well suited for larger screens that require more structural strength. This product passes and exceeds Australian Standards.

Invisi-Maxx – A commercial style frame that is designed to withstand severe weather. It has the largest gauge frame of our range and can be used in category 4 cyclone areas. It will offer maximum impact protection from wind-borne debris and can protect your premises in wind speeds of up to 356km/hr. It is well suited for extremely large doors or sliding doors.

We also offer three aluminium mesh security systems and a grille system. Grille security screens, like the popular Diamond Grille, provide a barrier against intruders and bugs and can be custom made to suit any hinged doors, sliding screen doors or windows.

Whilst the main focus of our security screens is the screen itself, we also take a lot of care to ensure our security screen locks are of premium quality. Locks are often forgotten about during the buying process, but a cheap lock will succumb to wear and tear much quicker and will no doubt cause plenty of frustration.

Our locks are made by Swedish Lock manufacturer Assa Abloy. Not only is Assa Abloy the world’s largest lock manufacturer by sales volume, it is also the parent company behind Lockwood, Whitco and many other brands.

Security Screen Configurations

There are a number of layout options to consider when installing a security screen door.

Choosing the right option will all depend on the design of your home and your own personal preference. The standard configurations include hinged doors, sliding doors, double doors and stacking doors.

Window screens are available as fixed and fire escape.

Security Screen Pricing

The price of your security screen is determined by a number of factors. These include type, colour, configuration, size and whether any framing is required.

As you will see below, a higher security rating or any additions like framing will attract a higher price.
