A customer in Smithfield rang us after getting roller shutters fitted to every window on the house. He was thrilled with them. The rooms were cooler, quieter and darker when he wanted them to be. Then he asked a question we hear often: “What about the doors?”
His front door was a standard timber door with nothing in front of it. The back slider opened onto a patio. On warm evenings the family wanted those doors open for the breeze, and they weren’t comfortable doing it with nothing between the house and the yard.
That’s the gap security doors fill. Roller shutters and security doors are often compared as if you have to pick one. In practice they do different jobs on different parts of the house, and a lot of Adelaide homeowners end up with both.
At Shutter Plus SA we manufacture and install roller shutters, and we make security doors and screens to measure, all in South Australia. This guide explains what each product does best, where each one falls short, and how to decide where your money should go first.
Key Takeaway: Roller shutters protect and insulate your windows. Security doors protect your doors while letting you keep them open for airflow. They solve different problems, so the question is rarely “which one?” and more often “which one first?”
What Each Product Actually Does
Roller shutters
A roller shutter is an external, slatted barrier that rolls down over a window or door opening. The foam-filled aluminium slats give you a physical security barrier, plus insulation against summer heat and winter cold, noise reduction of up to 50%, and strong light control. When it’s closed, it’s a solid wall in front of the glass.
Security doors and screens
A security door is a hinged or sliding door frame fitted with a tough mesh or grille and a quality lock. It sits in front of your existing front, back or patio door. You can leave your main door open for fresh air and light while the security door stays closed and locked. Security screens do the same job for windows and openings, and fly screen options add insect protection.
Put simply: a roller shutter is a wall you lower in front of an opening. A security door is a see-through, breathable barrier you can stay behind with the main door open.
Security Doors vs Roller Shutters – Side by Side
| Feature | Security doors | Roller shutters |
| Main job | Secure doorways while allowing airflow | Secure and insulate windows and openings |

| Visibility through it | Good – you can see out | None when closed |
| Heat reduction | Minimal | Strong – up to 90% summer heat reduction |
| Winter insulation | Minimal | Up to 70% heat loss reduction |
| Noise reduction | Minimal | Up to 50% |
| Blackout | No | Yes, when closed |
| Insect protection | Available with fly screen options | No |

Where Security Doors Win
- Doors you want open on warm nights – the single biggest benefit. Adelaide summer evenings make this a daily reality for many households.
- Front doors – a security door adds a second, locked layer in front of the main door, and lets in light and air.
- Sliding and patio doors – a security slider lets the main glass door stay open while the screen stays locked.
- Pets and kids – a closed security door keeps pets in and little ones from wandering out. We’ve installed security screen doors with pet door options for customers.
- Insects – a fly screen option keeps mozzies and flies out, something a roller shutter can’t do.
- Visibility – you can see who’s at the door and what’s happening outside without opening anything.
Where Roller Shutters Win
- Heat and cold – external foam-filled slats stop heat before it reaches the glass. This is the big one for west and north-facing Adelaide rooms.
- Noise – noticeable near busy roads and flight paths.
- Blackout and privacy – bedrooms, nurseries, shift workers and media rooms.
- Large windows – a roller shutter covers big glass areas that a security screen alone can’t insulate.
- Whole-house energy savings – the thermal benefit applies to every window you cover.
Tip: Think about how you live, not just what you want to protect. If you want your doors open on hot evenings, you need a security door. If you want cooler, quieter, darker rooms, you need roller shutters. Most households want both.
Why Many Adelaide Homeowners Use Both
A house has two kinds of openings: windows and doors. They’re threatened differently, used differently and need different solutions.
Windows are mostly closed. You want them to block heat, cold, noise and light, and to be hard to force. That’s a roller shutter’s job. Doors are opened and closed constantly, and in summer you want them open. That’s what a security door is built for.
Using only one leaves a gap. Shutters on every window but nothing in front of the doors means your doors are either shut (stuffy) or open (unprotected). Security doors only means your windows still bake in summer and are protected only by the glass and latch.
Together, the two cover the whole envelope of the house: the shutters handle the windows, the security doors handle the doors, and you can live in the house the way you actually want to.
Real Adelaide Scenarios – What We’d Recommend
Scenario 1: Family home in Smithfield, hot west-facing bedrooms, kids in and out all day
Roller shutters on the west-facing bedroom windows for heat and sleep. A security door at the back slider so the family can leave the glass door open while kids and the dog play in the yard. Front security door as a second step.
Scenario 2: Retiree couple in Tea Tree Gully, home most days, love fresh air
Security doors on the front and back first – they want breeze and light without worrying about the doors being open. Roller shutters on the bedroom windows next, for heat and a better night’s sleep. Electric operation on the shutters makes daily use effortless.
Scenario 3: FIFO worker in Two Wells, away for weeks at a time
Both, and both properly. Roller shutters on all accessible windows. Security doors on the front, back and patio doors. Timer-controlled electric shutters help the home look lived-in while the owner is away. Layering matters most when a home is empty.
If You Can Only Do One First, Which Should It Be?
It depends on your biggest problem.
- Hot rooms, poor sleep, noise, or high energy bills – start with roller shutters on the worst rooms (usually west and north-facing).
- You want your doors open for airflow safely – start with a security door on the door you open most.
- Your priority is overall security on a limited budget – look at which entry points are most exposed and least visible from the street. Often that’s a rear door or a back window. Cover the weak point first.
- You’re about to go away for an extended period – secure the doors and ground-floor windows that are easy to reach.
A site visit usually makes this clear. We look at which openings are most exposed, which rooms get the heat, and how you use the house, and suggest an order that makes sense for your budget.
What to Check Before You Buy Either Product
- Is it made to measure? Off-the-shelf doors rarely fit Adelaide homes properly. Gaps weaken both security and appearance. Our security doors and screens are made to measure.
- How is it locked? Ask what lock the door uses and how it’s fitted to the frame. A strong door on a weak lock isn’t strong.
- Is the product tested to the relevant Australian Standard? Ask the supplier to confirm what standard the product is tested to.
- What’s the warranty? Make sure the warranty covers both the product and the installation.
- Who installs it? A good product installed badly performs badly. Ask whether installers are in-house or subcontracted.
- Where is it made? Local manufacture means faster repairs and easier parts access.
Key Takeaway: A well-made product that’s measured and installed properly is worth more than a cheaper product that isn’t. Ask where it’s made, how it’s locked and who installs it.
