Only One Front Door? Why a Security Screen Door Is a Practical Upgrade

Many new homes are handed over with a single solid front entry door. There is nothing inherently wrong with this arrangement, but it limits how the entrance can be used.

When the solid door is closed, the house loses a potentially useful source of natural airflow. When it is open, flies, mosquitoes and other insects can enter freely, and there is no physical barrier between the interior of the home and anyone approaching the front entrance.

In many cases, the solution does not require replacing the existing front door or rebuilding the entrance. A separate screen, barrier or security screen door can be fitted externally over the existing door, provided the frame, dimensions and clearances are suitable.

Standard-sized screen and security doors are available from retailers such as Bunnings, including models with insect mesh, metal grilles, locks and left- or right-hand opening configurations. Custom-sized and adjustable products are also available for entrances that do not match standard dimensions.

How the additional door works

The original solid entry door remains in place and continues to provide privacy, weather protection, insulation and the main visual appearance of the entrance.

The new screen door is installed outside it. The two doors operate independently:

• the solid front door normally opens inwards;
• the screen door normally opens outwards;
• the screen door can be closed and locked while the solid door remains open; and
• both doors can be closed and locked when additional privacy, weather protection or security is required.

A practical screen door may include flyscreen mesh, a steel or aluminium grille, a keyed lock, an internal snib and a door closer. The mesh helps keep insects outside, while the grille and lock create an additional physical barrier at the entrance.

This does not make the home burglar-proof. However, it means that an intruder cannot simply walk through an open doorway, and it provides a visible obstacle that may discourage an opportunistic attempt to enter.

Better ventilation without inviting insects inside

One of the greatest advantages is the ability to leave the solid front door open while keeping the screen door closed.

The front entrance is often connected to a hallway, living room or open-plan kitchen area. When the front door is opened together with windows or a rear door elsewhere in the house, it may create useful cross-ventilation.

Fresh air can move through the home instead of entering through only one small window. This can be particularly helpful on mild days when the weather is comfortable but the house feels warm or stuffy.

During cooler evenings, the screen door may also allow outside air to enter while the solid door remains open. Depending on the house design, orientation and surrounding conditions, this may reduce the need to operate air-conditioning simply to refresh the indoor air.

At the same time, the flyscreen mesh helps prevent flies, mosquitoes, moths and other insects from entering through the open doorway. For the best result, the mesh needs to be intact and the gaps around the sides, top and bottom of the door must be properly controlled.

Particularly useful when cooking

An additional screen door can be surprisingly useful in a home with an open-plan kitchen.

Cooking steak in a very hot pan can produce smoke even when the food is not burning. Bacon, fish, stir-fries and other high-temperature cooking can also create steam, odours, heat and airborne grease.

If the kitchen rangehood does not remove the fumes quickly enough, smoke can move into the living area and towards a smoke alarm. Opening the solid front door may help create a stronger airflow path through the house, while the locked screen door continues to keep insects and unexpected visitors outside.

Fire and Rescue NSW advises occupants to operate available fans and vents and, where possible, open windows before cooking to reduce unwanted alarm activations. It also emphasises that cooking must not be left unattended. A screen door can assist with ventilation, but it does not replace an effective rangehood, safe cooking practices or working smoke alarms. Smoke alarms should never be disabled merely because cooking sometimes activates them.

A more comfortable way to answer the door

A locked screen door also creates separation between the occupants and a visitor.

The solid door can be opened while the screen door remains closed. This allows the occupant to speak with a delivery driver, salesperson or unfamiliar visitor without immediately providing unrestricted access to the home.

This can be convenient for families with children, people working from home and anyone who regularly receives deliveries. It may also help prevent a pet from running through the front entrance when the main door is opened, although a screen door is not a substitute for proper pet control or child supervision.

It can be used during the day or at night

A suitable screen or security door can be locked independently during the day or at night.

During the day, the solid door can remain open to provide airflow and natural light while the screen door is closed. At night, some owners use the same arrangement to bring cooler air into the home.

However, the appropriate level of security depends on the type of door. A lightweight flyscreen door is primarily intended to control insects. A basic barrier door with a grille and single lock provides a more substantial obstacle, but it may not provide the same level of protection as a tested security screen door.

Anyone planning to leave the solid door open for long periods, particularly overnight, should select the product according to its actual security performance rather than its appearance or marketing description.

Not every screen door is a security door

The terms flyscreen door, barrier door and security screen door are sometimes used as though they mean the same thing. They do not necessarily provide the same level of protection.

A basic flyscreen door usually consists of a lightweight frame and ordinary insect mesh. It can improve ventilation and keep insects outside, but the mesh is not intended to resist forced entry.

A grille or barrier door generally adds a metal grille, stronger frame and lock. This creates a visible physical obstacle and may be sufficient for an owner whose main priorities are ventilation, insect protection and basic separation from the entrance.

A genuine security screen door should have documented performance appropriate to its classification. The current Australian framework includes AS 5039.1:2023 for the classification and performance of security door and window screens and AS 5039.2:2024 for their installation. A strong door leaf attached incorrectly to a weak or unsuitable frame will not provide the intended result, so both the product and its installation matter.

NSW Police home-security guidance also recommends that security and screen doors be designed and installed in accordance with the applicable Australian Standards.

Reinforced security mesh is another option

A metal grille is not the only way to strengthen a screen door.

More advanced products can use reinforced stainless-steel woven mesh or perforated aluminium security mesh. These systems can provide ventilation and insect protection while offering a clearer view than a traditional diamond-pattern grille.

They are sometimes described as reinforced, high-security or “invisible” security screens. The word reinforced by itself does not prove a particular level of protection. The owner should confirm the product classification, test information, frame construction, locking system and installation method.

These doors are usually more expensive than ordinary fibreglass flyscreen or a basic grille door, but they may provide a cleaner appearance and a higher level of resistance to impact, cutting, pulling or attempts to force the door away from its frame.

Check the existing entrance before buying

A ready-made screen door can be a relatively straightforward upgrade, but it is important to measure the entrance correctly.

The required measurement is not necessarily the size printed on the existing solid door. The installer must assess the external opening where the new frame, hinges and lock will actually sit.

Before purchasing a door, check:

• the exact width and height of the opening;
• whether the opening is metric or imperial;
• the required hinge side;
• whether the screen door will have enough room to open outwards;
• whether the screen-door handle will clash with the existing front-door handle;
• whether the jamb is wide and strong enough for the hinges and lock;
• the position of the threshold and any weather seals;
• whether stairs, walls, columns or landscaping obstruct the outward swing;
• the required colour and finish; and
• whether corrosion-resistant materials and fixings are required for the location.

Some newer entry designs have narrow jambs, large sidelights, oversized doors, pivot doors or architectural frames that do not readily accept a standard external screen door. In these situations, a custom-made frame or a different installation method may be necessary.

For a door intended to provide genuine security, professional installation is generally preferable. The frame, hinges, strike, fasteners and surrounding construction all need to work as one system.

The internal locking arrangement should also allow occupants to leave the house promptly during an emergency. A locking method should not create a situation in which someone becomes trapped because the required key cannot be found.

The more expensive alternative: replace the complete entry frame

It is, of course, possible to take a more comprehensive approach.

The existing front door, jamb and surrounding trims can be removed and replaced with a purpose-designed two-door entry system. This can include a matching solid entry door and a separate flyscreen or security screen door designed to operate together.

A premium system may include reinforced stainless-steel security mesh, a stronger external frame, upgraded hinges, a multi-point locking system and hardware selected specifically for the complete entrance.

This can produce a neater and more integrated result than adding a standard screen door to an existing frame. It may be the better option where the current jamb is unsuitable, damaged or poorly designed, or where the owner wants to upgrade the appearance and security of the entire front entrance.

However, replacing the complete assembly is considerably more expensive.

The cost may include:

• the new solid entry door;
• the screen or security door;
• a replacement jamb and frame;
• hinges, locks and handles;
• removal and disposal of the existing assembly;
• new architraves and trims;
• painting or staining;
• threshold and weatherproofing work;
• adjustments to flooring, cladding, render or brickwork; and
• professional installation and finishing.

For many homes, replacing the entire frame is unnecessary if the existing entrance is in good condition and can accept a properly fitted external screen door. The simpler add-on option can deliver most of the everyday benefits at a substantially lower cost.

Which option makes the most sense?

The right choice depends on what the owner expects the additional door to do.

Where the main purpose is airflow and insect control, a well-fitted flyscreen door may be sufficient.

Where the owner also wants a visible grille, lock and additional barrier, a grille or barrier door can provide a practical middle option.

Where security is the main priority, a tested security screen with appropriate locks, frame construction and professional installation is the more suitable choice.

Where the existing entrance is unsuitable or the owner wants a premium integrated result, replacing the complete jamb and installing a purpose-designed solid-door and security-screen combination may be justified despite the higher cost.

The important point is that a house delivered with only one solid front door does not necessarily have to remain that way. In many cases, a separate lockable screen door can be added without major reconstruction, making the entrance more useful every day.

How ARK Houses can help

At ARK Houses, we consider how an entrance will work in everyday life, not only how it will appear on the plans. When designing a new house, duplex or dual key property, or upgrading an existing home, we can allow for a correctly sized frame, compatible handles, suitable opening clearances and an appropriate flyscreen, barrier or security screen door. Where a home has already been built with only a single front door, we can assess whether a straightforward external screen-door installation is suitable or whether replacing the complete entry assembly would provide a better long-term result.
