They can look similar from across the room, but flyscreens and security screens do very different jobs. Here's how to tell them apart, and which one belongs on which opening.
The short answer
A flyscreen keeps insects out. A security screen is built to keep people out, with tougher mesh, a stronger frame and proper locking hardware. If you want to open the house up to the breeze without the mozzies, a flyscreen does the job. If you also want a barrier on a door or window you can lock, you're looking at a security screen.
What a flyscreen does
Flyscreens and insect screens use a light mesh in a slim frame. They're made to fit your window or door opening exactly, so there are no gaps for bugs to find, and they're the simplest way to ventilate a room. They aren't designed to resist forced entry and shouldn't be treated as a security measure.
What a security screen does
Our Ultra Stainless security screens and doors use woven stainless steel mesh in a strong frame, and every door comes with triple lock hardware. The mesh is fine enough to let light and air through, while the frame and locks are what make the difference if someone tries to force their way in. Our triple lock guide explains why the hardware matters as much as the mesh.
Diamond Grille is a different choice again: a classic diamond-pattern grille picked for its look. If style is your priority, our Diamond Grille vs Ultra Stainless comparison will help you decide.
Which one for which opening?
| Opening | Flyscreen | Security screen |
|---|---|---|
| Bedroom window you like open at night | Keeps insects out | Adds a locked barrier while the window stays open |
| Front door | Hinged flyscreen door | Security door with triple lock |
| Sliding door to the patio | Sliding flyscreen door | Sliding security door |
| Windows that are hard to reach | Often enough, depending on access | Optional extra layer |

Frequently asked questions
Can a flyscreen be used as a security screen?
No. Flyscreens use light mesh and slim frames that aren't designed to resist forced entry. If you want a security barrier, choose a security screen with proper locking hardware.
Do security screens keep insects out too?
That depends on the mesh. If keeping insects out matters as well as security, tell us when you request a quote so we can recommend the right product for each opening.
Which costs more, a flyscreen or a security screen?
Security screens generally cost more, because the mesh, frame and hardware are heavier duty. Your quote shows the price for each opening.
