Crimsafe security doors: keep your home safe and breezy

When it comes to safeguarding your home while enjoying the breeze, Crimsafe Security Doors are the ultimate choice. Not only do they allow you to keep your doors wide open day and night, but they also provide unmatched protection against intruders. Crimsafe screen doors are designed for security and peace of mind, ensuring that your home remains safe from all kinds of threats. Let’s delve into what makes Crimsafe doors the top pick.

This is likely your top concern, and the answer is reassuring: the only way a Crimsafe door will fail to protect against intrusion is if you leave it unlocked. But seriously, Crimsafe doors are crafted from materials specifically designed to withstand cutting, impacts, and even storm-driven debris with wind speeds up to 392 kph. When potential intruders see a Crimsafe door, they won’t even bother trying to break in—they’ll just keep walking.

While there are many ways criminals might attempt to enter a home, Crimsafe doors eliminate one of the most vulnerable entry points. One crucial tip from law enforcement for break-in prevention is installing a security screen door. Among the many options available, Crimsafe stands out as a proven leader. It not only meets but exceeds the stringent levels of strength, safety, and performance set by Australian Standards.

But has this been independently verified? Absolutely. In 2018, the University of New South Wales researched the impact resistance of various wire mesh security screens. The results showed that Crimsafe doors had the highest resistance to impact, confirming the effectiveness depicted in Crimsafe’s classic ads of intruders failing to breach Crimsafe doors.

Not only do Crimsafe doors allow you to enjoy the breeze, but they also provide peace of mind with their exceptional security features. Crimsafe Security Doors not only meet but exceed the stringent Australian Standard AS5039-2023 for resistance to forced entry. Here’s why Crimsafe stands out as a proven and reliable choice for Australian homes, backed by 25 years of research, development and unique safety technology.

Crimsafe’s Tensile-Tuff® stainless steel mesh is 26.5% thicker than competitors’, providing superior resistance to cutting and impact. This robust construction makes it the toughest security screen on the market.

The innovative Screw-Clamp™ Technology offers unparalleled strength. This system absorbs and disperses impact around the frame, ensuring the screen can withstand significant force without giving way.

Crimsafe doors feature tamper-resistant stainless steel screws that are virtually impossible to remove with conventional tools. The precision-engineered clip-in cover adds another layer of security by preventing access to the screws and protecting the hardware from environmental damage.

Crimsafe has  conducted numerous tests to prove its reliability and well-earned safety ratings, making it the best on the market. From strength and security to environmental resilience, here’s a closer look at the research backing Crimsafe’s claims.

Crimsafe doors can endure multiple impacts ranging from 550 joules (Crimsafe Regular) to 1200 joules (Crimsafe Heavy-Duty), tested under Australian Standards conditions. This is equivalent to withstanding the force of weights between 56 kg and 122 kg, respectively. No opportunistic criminal could apply that much force without drawing attention.

Intruders often carry small knives, considering them effective tools for slashing screens. However, Crimsafe’s structural-grade Tensile-Tuff® mesh passed every simulated knife attack, proving impenetrable under such conditions.

Apart from specialized license-held tools, no conventional tool can successfully tamper with Crimsafe Security Door technology. Even as a jemmy, Crimsafe’s lever-defiant design and clip-in cover offer no leverage, easily passing these tests.

The combination of Screw-Clamp™ technology and Tensile-Tuff® mesh withstands brute force from all angles. During simulated conditions, Crimsafe doors proved unyielding, effectively preventing any attempt to pull them down.

In real-world scenarios, Crimsafe screen doors face numerous challenges—from intrusion attempts to environmental conditions and pesky insects. Crimsafe doors have proven their durability and resilience against all these tests:

Corrosion Resistance: Withstands harsh coastal environments.

UV Radiation Exposure: Remains robust under intense sunlight.

Wind Gust and Storm Debris Impact: Holds firm against severe weather conditions.

Fire Attenuation and Bushfire Flame Zone: Provides protection in fire-prone areas.

Insect Protection: Effectively keeps out mosquitoes, one of the most persistent intruders.

When it comes to security doors, Crimsafe is our top recommendation at My Security Door. With over 35 years of innovation, unique design, and rigorous testing, Crimsafe doors have earned their reputation as the most trusted security screen doors available.

Keeping in mind Crimsafe’s Tensile-Tuff® mesh and Screw-Clamp™ technology provide unmatched strength.
