"Security vs. Barrier Doors: The Impact of Pet Flaps"

FAQ: "Is it still a Security Door?" No. Under Australian Standards (AS5039), adding a pet flap reclassifies a "security door" as a "barrier door."

Key Points

  • Loss of Certification: It no longer meets official security standards.
  • Reduced Protection: The opening creates a structural weak point.
  • Voided Warranty: Modification typically cancels manufacturer guarantees.
  • Summary: It remains a strong barrier, but loses its legal status as a certified security door.

"Best Ways to Upgrade that Barrier Door"

1. The "VIP"
(Microchip Doors)
If you're worried about the local stray cat or a particularly motivated carpet snake moving in, these only open for your pet's microchip.Brands: SureFlap or Aussie Pet Doors (High Tech series).Why it helps: It stays locked until your pet approaches. It won't stop a human with a sledgehammer, but it stops the "uninvited wildlife" house party.
2. The "Heavyweight Champ".
Top Picks: Petway or Prowler Proof 'compatible doors'.The Benefit: They use a 32mm wide fully welded aluminium frame. While it won't pass the official Australian Standard test anymore, it’s significantly harder to kick through than a standard flap.
3. The "Size Matters"!
The Fix: Install your pet door as far away from the lock and handle as humanly (and dog-edly) possible. You want convenience for your Rupert — not for burglars.
Size matters: If you have a tiny pup, buy the tiny door. Don’t future-proof for a hypothetical Great Dane you might adopt someday. Your current dog shouldn’t need a ladder to get through their own entrance.

Invisi-Gard Stainless Steel Security Solutions: Is It Right for You?
The Coastal Homeowner
Since 85% of Australians live within 50km of the sea, the Marine Grade 316 Stainless Steel High Tensile Wire (900MPa) is the biggest hook. We have all seen cheap screens "tea stain" and rust; Invisi-Gard is the cure.
The Outdoor Room
With the rise of alfresco living and "staycations," we find that homeowners are investing heavily in patios and pool enclosures. They want protection from bugs and intruders without losing the view with Invisi-Gard Window Security Screens, and Security Doors.
The Design Conscious
Many of our customers have spent $20k+ on a beautiful timber front door. They don't want a "diamond grille" cage hiding it. They want the "invisible" security of high-clarity mesh with Invisi-Gard.
The Buy Once Consumer
Millennials and Gen Xers who are tired of "disposable" products, the 15-year warranty appeals to their desire for long-term value with Invisi-Gard screens and doors.
