Security Doors: What you Need to Know Before Making your Next Purchase!

When buying a security door, most people will assume it’ll be strong and durable. However, you might be surprised that the strength and durability of a security door can differ considerably from one brand to another.

Safety and security is important to everyone and in many cases security doors are the only thing standing between you and the potentially dangerous areas of society.

Western Australia sees almost 30,000 homes broken into every single year. With this being more than 50% above the national average, West Aussies need to take our security seriously.

Therefore, it is extremely important that your security door meets all of your safety needs, without creating a gaping hole in your budget.

The following is a comprehensive list of things you should look for before making your next security door purchase.

Does it Include a Warranty?

Being the frontline defender of your home, security products have the potential to face serious damage. Aim for security doors with a minimum 7 year warranty.

How Does it Look?

Most brands of security screens come in a wide range of colours and finishes. Subsequently, you should be able to prioritise your safety without compromising on the beauty of your home.

Does the Style Suit your Door & Home?

It is also important to consider the look of your house and the material that your door is made from.

For example, timber-look security doors are now available from most home security companies which are a great fit for timber doors, while still being strong and durable. Similarly, colonial and federation style security screens are also  available for older style homes and businesses.

Is the Installer Licensed with a Police Clearance?

Without being licensed and holding a current police clearance, there’s no real way to know if you’re dealing with a trustworthy and ethical home security company. Within Western Australia, all reputable home security companies will hold the following –

  • Police Clearance
  • Security Agents License
  • Security Installer Licenses
  • Security Consultant Licenses

Do They Meet Australian Standards?

This is obviously the most important factor to consider.

Security doors and screens must withstand the force of 100 joules. For reference, that’s the same amount of force that an intruder would apply if they kicked the door 5 times. For Australian standards to be met, this force must not succeed in penetrating, or pushing the screen out or away from the frame.

Here are 3 popular residential stainless-steel security screens that pass Australian Standards:


Invisi-Lite security screens are designed for the average homeowner and pass all Australian security standards. Invisi-Lite screens offer maximum light and airflow, meaning you can be safe and secure without compromising the features of your front door. Invisi-Lite is backed by a 7-year warranty.


This screen uses a higher grade of stainless-steel mesh and comes backed by a 15-year warranty. Invisi-Gard screens are corrosion resistant and highly secure. They are perfect for larger doors that may require more strength by way of structure.  Invisi-Gard screens not only pass, but exceed Australian Standards.


Designed to withstand the most extreme weather including category 4 cyclones. Invisi-Maxx has the largest gauge frame of the Invisi range of security screens.

What Type of Lock?

A security door is only as secure as the lock that accompanies the door. As a rule of thumb, if you select a reputable brand you can rest assured you’re in good hands. Some trusted options in Australia include Lockwood, Austral, Whitco and Yale.

Can the Mesh be Cut with a Knife?

This is another important factor to consider. Some intruders will carry a knife and if they’re unable to kick in the door they may try to penetrate the mesh with the knife.

Can you see Inside Your House from the Outside?

Several leading security door manufacturers now produce screens that can be seen out from the inside, but not in from outside of the house. This allows you to see who is at the door without having to open the screen, while also preventing potential intruders from seeing inside your home.

Does the Security Screen Come in a Configuration that Suits Your Needs?

There are several configurations that could suit what you need for your home security screen including:

  • Single slide
  • Single centre slide
  • Double slide
  • Stacking
  • Double stacking
  • Single
  • Single 1200
  • Double door
  • Double cat & kitten
  • Single & sidelite

Consider your requirements and whether there is an appropriate configuration for your needs, for example – do you have a pet?
