Security Window Screens: The Forgotten Element of Home Security
A guide to security window screens as part of a complete home security perimeter, covering screen types, 316 marine-grade mesh, child safety and fall prevention under NSW rules, cost ranges, and how they differ from fly screens.
Key product notes
- An unprotected window is one of the easiest entry points into a home, so window screens are an essential part of a complete security perimeter rather than an optional extra.
- Tested security window screens use 316 marine-grade stainless steel mesh and a fixed, hinged or sliding frame, unlike fly screens, which only keep insects out.
- Fall-prevention and child-safe screens address NSW window safety requirements for high-risk windows and add genuine protection for young children.
- Window security screens typically cost $480 to $700 per window installed; Shire Security Doors and Screens quotes them free on 0410 474 256.
Why windows are the weak point in home security
Most homeowners secure the front door and forget the windows, yet an unprotected window is one of the easiest ways into a home. Security window screens close that gap by adding a tested mesh barrier over the opening while still allowing airflow and light, which is why they belong in any complete home security perimeter alongside security doors. In Sydney, expect to pay roughly $480 to $700 per window, with marine-grade options and a 10-year warranty at the premium end.
For a typical three-bedroom Sutherland Shire home with 8 to 10 windows, full window security screening generally ranges from $4,000 to $7,000 installed, a worthwhile investment given how often windows are the overlooked entry point.
- Windows are a common, easily overlooked entry point
- Security screens add a barrier without blocking airflow or light
- Roughly $480 to $700 per window installed in Sydney
- Full home screening: about $4,000 to $7,000 for an average home
Types of security window screens
Security window screens come in several configurations to suit different openings. Fixed screens are mounted permanently over the window for maximum strength and are ideal where the window does not need to open as an exit. Hinged screens swing open, which suits windows that are also used as an escape route, while sliding screens follow the line of sliding windows.
For upper-storey windows and homes with young children, Guardian-style fall-prevention screens combine a security barrier with a robust frame designed to resist a child leaning or falling against it. The right type depends on how the window is used for ventilation, views and emergency egress.
- Fixed screens: maximum strength for non-egress windows
- Hinged screens: open for cleaning and emergency exit
- Sliding screens: follow sliding window openings
- Guardian fall-prevention screens: child safety on upper-storey windows
Why 316 marine-grade mesh matters on windows
Window screens face the same salt air, humidity and weathering as security doors, so mesh grade is just as important. 316 marine-grade stainless steel mesh is selected for corrosion resistance in aggressive coastal environments, making it the right choice for Shire suburbs such as Cronulla, Burraneer and Sylvania Waters. The same ForceField mesh used on doors carries a 10-year warranty when used on windows.
Inland or low-exposure homes can use 304 grade or quality alternatives at lower cost, but anywhere within a few kilometres of the surf the 316 grade is the sensible long-term specification.
- 316 marine-grade mesh resists coastal corrosion
- Same 10-year warranty as ForceField doors
- Best for salt-air suburbs near the water
- 304 grade can suit inland, lower-exposure homes
Child safety and fall prevention
Window safety is a genuine, regulated concern in NSW. Planning rules require window safety devices on high-risk windows in houses and townhouses, including older homes, to prevent children falling from height. The scale of the problem is significant: between 1998 and 2008 The Children's Hospital at Westmead treated 171 children for falls from windows and balconies, including two fatalities.
Fall-prevention security screens address this by providing a robust barrier that a child cannot push out, while still allowing the window to open for ventilation. Crucially, screens on bedrooms and living areas should include a quick-release egress mechanism so the window can still be used as an emergency exit by adults.
- NSW rules require safety devices on high-risk windows, including in older homes
- 171 children treated for window and balcony falls at Westmead, 1998 to 2008, with two fatalities
- Fall-prevention screens stop a child pushing out while allowing airflow
- Quick-release egress keeps the window usable as an emergency exit
What do security window screens cost?
Window screen pricing follows the same mesh and frame logic as doors. A standard hinged or fixed window screen runs about $480 to $700 per window installed, large feature or picture windows $700 to $950, and sliding window screens $550 to $800. Custom shapes such as arches, and quick-release escape mechanisms for bedrooms, add to the cost but are often essential.
Screening multiple windows in one visit is the most cost-effective approach, and bundling windows with a security door quote usually delivers the best overall value for a complete perimeter.
- Standard hinged or fixed window screen: $480 to $700
- Large feature or picture windows: $700 to $950
- Sliding window security screens: $550 to $800
- Bundle windows with a door quote for best value
Security window screens versus fly screens
The two products look similar but do very different jobs. A fly screen uses light insect mesh in a light frame and is designed only to keep bugs out; it offers no resistance to forced entry. A security window screen uses high-tensile stainless steel mesh in a strong, fixed frame and is built to resist intrusion while still keeping insects out.
If security is part of the goal, a fly screen is not a substitute. The right choice is a tested security window screen, which delivers insect protection as a bonus rather than as its only function.
- Fly screen: insect protection only, no forced-entry resistance
- Security screen: stainless steel mesh built to resist intrusion
- Security screens keep insects out as a bonus
- A fly screen is not a security substitute

Frequently asked questions
Are security window screens worth it?
Yes. Windows are one of the easiest entry points into a home, so security window screens are an essential part of a complete security perimeter. They add a tested mesh barrier while still allowing airflow and light, and on coastal homes the marine-grade mesh resists salt-air corrosion for the long term.
What is the difference between a security window screen and a fly screen?
A fly screen uses light insect mesh in a light frame and only keeps bugs out, offering no resistance to forced entry. A security window screen uses high-tensile stainless steel mesh in a strong frame built to resist intrusion, while keeping insects out as a bonus. A fly screen is not a security substitute.
Do I need fall-prevention screens for my children?
If you have young children and windows at height, yes. NSW rules require window safety devices on high-risk windows in houses and townhouses, including older homes. Fall-prevention security screens provide a robust barrier a child cannot push out, while a quick-release mechanism keeps the window usable as an emergency exit.
What mesh is best for window security screens near the coast?
316 marine-grade stainless steel mesh is the best choice within a few kilometres of the coast because it resists salt-air corrosion far better than 304 grade or aluminium. It carries the same 10-year warranty as ForceField doors. Inland homes can use 304 grade or quality alternatives at lower cost.
How much do security window screens cost?
Standard hinged or fixed window screens cost about $480 to $700 per window installed, large feature windows $700 to $950, and sliding screens $550 to $800. Full window screening for an average three-bedroom home generally ranges from $4,000 to $7,000. Bundling windows with a door quote usually gives the best value.
Can security window screens still be used as a fire escape?
Yes, when specified correctly. Screens on bedrooms and living areas should include a quick-release egress mechanism so the window can still be used as an emergency exit while remaining secure day to day. We confirm which openings need egress hardware during the on-site measure.
