Is there really a louver window with “impenetrable security”?

Breezway Louvers

Claims of “impenetrable” security should always be met with some scepticism. After all, ‘impenetrable’ is a pretty big claim! Would it resist a crowbar, or a hammer? What about a bull-dozer, or the jaws of life?

And even if a window was ‘impenetrable’, would it offer any real advantage if an intruder could simply break in through a door or through the ceiling?

As with all security measures, a balance must be struck between the level of security required, cost and other benefits or disadvantages of the security features under consideration.

Louver Window Security Options
The customizing choices available from Breezway Louver Windows extend beyond framing, sizes, colors, handle types and blade types to include an array of security options too.
Even without any of the customizing options, security is built in to the basic design of the Breezway Louver. When closed, firm locking pressure makes it exceedingly difficult to prise the window open.

Security Screens
Available as woven metal mesh screens or metal grill screens, security screens protect the window both when it is open and when it is closed. This could be an important consideration if the windows are to be left open while homeowners are not home or asleep. There is a wide range of security screens available with most window fabricators able to supply and securely install security screens.

Tip: Always check whether the security screens being considered have passed testing to the relevant Standard, also a quality installation is critical to the performance of the screen.

Security screens have some additional benefits, but also some disadvantages.

Security screens provide some shade to the window which can help avoid homes overheating during summertime and when the windows are closed, screens reduce the movement of air next to the window which results in insulating properties better than many double glazed windows.

There are downsides to screens though, the reduced airflow caused by the mesh which improves the insulating properties of the window also reduces the desirable cooling ventilation when the window is open. Screens also obscure views through windows.
