How to Select the Perfect Sliding Screen Doors for Your Home

Sliding Security Doors

Sliding security doors are a tried and true way to secure your home. However, knowing the ideal options for your requirements can take time and effort with so many manufacturers, installers, types and door styles. We have developed this guide to help speed up your decision process without making costly errors.

Here are the main factors you should consider when selecting your sliding screen doors –


Most sliding screen doors are now manufactured from stainless steel or aluminium. Stainless steel offers superior strength; however, it’s essential to understand the different grades of stainless steel. Check out our recent article on security mesh doors, which explains this in more detail.

Perforated aluminium security doors can still offer excellent security and provide an affordable, attractive and lightweight solution. KNA Security can supply and install a variety of 316 marine-grade stainless steel and perforated aluminium doors to meet just about any requirement.

If you live near the coast or in cyclone-prone areas, you’ll need to select materials that are resistant to corrosion and/or designed to withstand cyclonic conditions. Our Invisi-Maxx option is the most formidable security door on the market, and its 1.2mm mesh is rated for Region D: Cyclonic Areas with wind speeds up to 324km per hour!

Our steel security doors are available as alfresco enclosures, hinged security doors, sliding security doors, double security doors and security window screens. You can even add a pet door to allow your cats or dogs an easy entry and exit point to your home.

The ideal configuration for your requirements will generally be dictated by the size of your door or entry point; however, it’s essential to keep this in mind and select a style that suits your needs.

Sliding Security Screen Doors


Security is the primary reason that most people install sliding screen doors. As a starting point, your doors and screens should meet, if not exceed, Australian Standards.

If security is paramount, we recommend a 316 marine-grade stainless steel door with a robust triple lock, which offers the highest security/strength rating on the market.

Sliding Security Doors - Ratings


Many of our customers select screens with a high level of airflow because it allows them to enjoy Perth’s afternoon sea breeze while keeping their homes secure.

On the other hand, some people elect for a low airflow rating because they want to keep out the hot air or neighbouring odours. Make sure you select a screen that offers the ideal level of airflow for your requirements.


Sliding screen doors also offer various levels of visibility and privacy. You may want to prevent visitors or intruders from seeing into your home from the outside, whereby you’ll want a screen with a high level of visibility and privacy.

You can even select a screen that allows you to “see out but not in”. Again, be sure to select a door and screen with the ideal level of privacy and security to meet your needs.

At KNA Security, we have developed a grading system to take the guesswork out of rating each door type. You’ll see a star rating next to each type of door and screen, which rates the security, airflow, visibility and privacy out of five stars.
