If you’ve recently installed bifold doors, you already know how much they transform your living space — more light, airflow, and that seamless connection to the outdoors. But to keep bugs and mozzies out without spoiling the view, retractable fly screens are a must.

At RetractAscreen, we offer two distinct options for bifold doors: Single Retractable Screens and Dual Retractable Screens.
Both are custom-made, both look stunning, and both deliver smooth, effortless operation — but which one is right for you?

Let’s break it down.

What’s the Difference Between Single and Dual Retractable Fly Screens?

The main difference comes down to how wide your bifold door opening is and how you’d like the screen to open and close.

Single Retractable Fly Screen

A Single Screen System covers openings up to 4.5 metres wide in one continuous span.
It’s perfect for:

  • Smaller bifold door setups (typically 2–3 panels)

  • Everyday family access points

  • Homeowners who want a sleek, one-way glide

Benefits:

  • Minimalist design with only one cassette

  • Quick and simple to operate with one hand

  • Ideal for narrower openings and frequent use

Because it retracts into one side, it maintains a clean, uninterrupted look — ideal for compact alfresco areas, courtyards, or kitchen bifolds.

Dual Retractable Fly Screen

For larger openings, up to 9 metres wide, the Dual Screen System is the better choice.
This design uses two retractable screens that glide towards the centre and meet neatly in the middle with a magnetic seal.

Best suited for:

  • Wide-span bifold doors (4.5m – 9m)

  • Open-plan living areas and entertainment zones

  • Coastal or garden-view homes with large openings

Benefits:

  • Even tension across a wide space — no mesh sagging

  • Balanced, symmetrical appearance

  • Greater flexibility — open one side or both

  • Perfect for large gatherings and airflow

If your bifold doors lead to a patio or pool area, Dual Screens are ideal — they let you enjoy Melbourne’s sea breeze without the flies.

Aesthetic and Design Considerations

From a design perspective, both Single and Dual retractable screens integrate beautifully with your bifold frames.
They come in nine standard Colorbond® colours (and other custom finishes) to blend with your doors, whether they’re aluminium, timber, or PVC.

For narrow doorways, the single screen’s minimal frame can look sleeker; for wider spaces, the symmetrical meeting point of the dual system often suits the architectural balance of large bifold installations.

Ease of Use and Maintenance

Both systems are designed for smooth, one-hand operation and use durable mesh engineered for Australian conditions.
Cleaning is simple — just vacuum the track, gently wipe the mesh, and you’re done.

When professionally installed, either system will stay aligned and glide effortlessly for years.

Choosing the Right System for Your Home

Here’s a quick guide:

Door Width Recommended Screen Type Ideal Use Case
Up to 4.5m Single Retractable Screen Standard bifold doors, patios, courtyards
4.5m – 9m Dual Retractable Screen Large openings, entertainment areas, pool decks

If you’re unsure which setup fits your home best, our installation team can measure your opening and recommend the right option for both aesthetics and practicality.

Australian-Made Quality You Can Trust

Like all RetractAscreens, both our Single and Dual retractable fly screens are manufactured in Australia for durability and quick turnaround times.
With custom sizing, premium mesh options, and precision installation, you can be confident your screen will fit perfectly and last through many Melbourne summers.
