Althaus Security Screens & Doors

Four Generations. One Town.

One Standard.

My grandfather on my mother’s side built homes in Toowoomba. My father painted them for 45 years. I have been manufacturing and installing Crimsafe security screens and doors for 30 years. Now my son Brodie is building his own business in the same town.


Two sides of my family. Same town. Same standard — never written down, just lived.


Althaus Security is built on that foundation. Toowoomba’s first authorised Crimsafe manufacturer and installer — since 1996.

Frequently Asked Questions About Crimsafe Security Screens

  • Q: What is a security screen?

    A: A security screen is a specialised physical barrier to entry that allows airflow while keeping insects and intruders out. To be called a security screen, these products must pass strict testing to Australian Standard 5039 and be fitted with compliance labels. 

  • Q: Do security doors need 3-point locks?

    A: Yes - to comply with Australian Standards. Security doors must pass strict testing to Australian Standards and this almost always means being fitted with a 3-point lock, which secures the door at the top, middle and bottom. 

  • Q: What is the best security door?

    A: The best security door is one that has passed testing to Australian Standards and is fitted with a compliance label. Be on the lookout for fakes. If it's not labelled, it's not a security screen.  

  • Q: What is a Compliance Label?

    A: The AS 5039 Compliance Label is an official label applied to a security door or screen that indicates it has been manufactured and tested in accordance with the Australian Standard AS 5039.

    This label provides peace of mind that the product you have bought meets specific requirements for materials, construction and locking system.  If your security screen product is not installed with a Compliance Label, it's not compliant - it's that simple. 

  • Q: Does my security screen installer need to be licensed?

    A: In many states, security screen installers need to be licensed. Check the NSSA website for details on licensing in your state. 

  • Q: Can I fit my own security door?

    A: Compliant security screen doors are made and installed to very tight tolerances with specialised fixings. While you may be able to put a screen up and make it operate, the product may not provide proper security. The NSSA always recommends installation by an NSSA Member - Don't DIY.

  • Q: Why buy from a member of the National Security Screen Association?

    A: The NSSA provides education, training, and accreditation to its members to ensure they provide the best outcomes for consumers. NSSA members must meet compliance obligations and provide transparent product information to homeowners.

  • Q: Are barrier doors the same as security doors?

    A: No. The term “barrier door” is often used to describe a screen that won’t pass the Australian Standard testing process. These inferior products may also be called safety screens and similar terminology to avoid scrutiny. Don’t get ripped off. Ensure your Security Screen has an AS5039 Compliance label. 

  • Q: Should I get security cameras or security screens?

    A: Security screens provide a physical barrier to entry. While cameras can be good for monitoring what has happened, they cannot stop a break-in. 

  • Q: How do I know I am buying the right screen.

    A: It's simple - Buy a compliant security screen product with a compliance label from an NSSA Member. This is the easiest way to know you are buying real security.

Called Wayne to have a crimsafe door installed.Excellent service from Wayne and Rodney who fitted the door. Door looks and feels solid, perfect fitment into the jamb and well finished. I regret not getting Althaus to do all our screens and doors when we built, absolute quality, worth every cent.

We've recently had Crimsafe security installed by Althaus here in Kearneys Spring. Althaus Security worked very efficiently form day one. Wayne was quick to reply to my text and came on the same day to have measurements done, and you could see that Rodney never rushed and was precise when it came to installation. Very pleased with the job overall .

Just had the pleasure of dealing with Wayne. Better than good service. Brilliant service more like. Sometimes people go right out of their way to help and Wayne is definitely one of those. Can not recommend this business quality, knowledge and service high enough. Thank you and what a relief to get the door fixed.
