Introduction
Patio doors are the perfect way to connect your indoor space with the outdoors—but when summer arrives, there’s one downside: flies and insects. Whether you’ve got elegant bifold doors, sleek sliding patio doors, or traditional French doors, you might be wondering if there’s a smart, stylish way to enjoy fresh air without letting bugs in.
In this guide, we’ll explore fly screen options for patio doors, practical alternatives you can use with GFD’s door systems, and expert advice to keep your space breezy and bug-free.
What Are Patio Doors?
Patio doors are large glazed door systems that provide access to outdoor areas such as gardens, patios, or balconies—while also letting in maximum light. At GFD Homes, we offer three main types of patio doors, each with its own distinct benefits:
Bifold Patio Doors
Bifold doors consist of multiple panels that fold neatly to one or both sides, creating a wide, unobstructed opening between your indoor and outdoor spaces.
- Great for creating a “wow” factor
- Ideal for entertaining and open-plan living
- Can open partially or fully for flexible use

Sliding Patio Doors
Sliding doors feature large glass panels that slide behind each other along a track, offering a clean, minimal look with maximum glass area.
- Excellent for limited outdoor space
- Slimline profiles mean more light and views
- Perfect for modern and contemporary homes

French Patio Doors
French doors are a timeless classic, with double doors that open outward or inward from the centre.
- Great for traditional and cottage-style homes
- Easier to add fly screens or integral blinds
- Adds charm and symmetry to rear or side elevations

Fly Screens & Modern Patio Doors – A Compatibility Challenge
When people search for the best fly screen for patio doors, they’re often thinking of traditional mesh solutions. But with today’s slimline, frameless, and wide-opening systems like bifold and sliding doors, adding a fly screen isn’t always straightforward.
Here’s why:
- Most GFD patio doors are full-glass panels with minimal frames, which may make it trickier to find a natural fixing point
- Opening styles like bifolds and sliders need full clearance to operate smoothly
- Fly screens can interfere with tracks, stacking panels, or low thresholds
- Permanent screens can spoil the clean, uninterrupted views
That’s why we don’t offer fly screens as standard—but that doesn’t mean you’re without options.
Smart Alternatives to Fly Screens for Patio Doors
While retractable fly screens or magnetic fly screens may work for smaller doors or windows, here are three smart alternatives better suited to GFD’s patio systems:
1. Integral Blinds in Glass
Instead of using mesh or curtains to create a barrier, opt for blinds sealed inside the glazing unit. These won’t stop bugs, but they provide:
- Privacy
- Shade control
- A clean, cord-free look
- No interference with doors opening or stacking
Ideal for bifold doors with side panels or French doors with glass panes.
2. External Shade Systems or Pergolas
For garden-facing patios, creating an outdoor living zone with a covered seating area can help reduce bug traffic and heat buildup—keeping doors open without attracting insects.
3. Room Zoning with Screens or Net Panels (Non-Fixed)
Use freestanding screens or curtain-style nets that can be pulled across just while doors are open—these can be removed easily and don’t interfere with door operation.
Ventilation Tips Without the Flies (Updated)
If you’re opening patio doors for airflow, there are smart ways to enjoy ventilation without letting bugs in.
Here’s what we recommend:
- Use citronella candles, essential oils, or natural repellents near open doors
- Keep nearby food and bins sealed—especially in warm months
- Try temporary net curtains or removable panel screens
- For French doors, use lightweight magnetic fly screens or retractable panels
Built-In Ventilation Options: Trickle Vents
Some of our patio door systems—such as the Smart bifold door—offer the option to add discreet, flush-fitting trickle vents. These are a fantastic way to achieve background ventilation without having to open the entire door.
- Keeps air circulating, even when the door is closed
- Helps reduce condensation and indoor humidity
- Flush fitting design maintains the door’s sleek appearance and modern aesthetic
Trickle vents are a subtle yet powerful upgrade—perfect if you want better air quality and a cleaner exterior look.
Ask our team about adding trickle vents when customising your door at checkout or during quote configuration.
Can You Put Fly Screens on French Doors?
Technically, yes—French doors are the most screen-friendly of all patio door types, thanks to their hinged, symmetrical opening.
You can find:
- Magnetic fly screens
- Sliding mesh panels
- Made-to-measure framed fly screens
However, it’s important to choose a screen that doesn’t obstruct handles, locks, or weather seals.
Top tip: Always consult your installer or supplier before adding anything to your French door frame—it could affect warranties or operation.
Conclusion
While traditional fly screen for patio doors can be difficult to fit on modern bifold and sliding systems, you can still enjoy fresh air without the insects. Many of our patio door ranges—like the Smart bifold door—come with the option to add discreet trickle vents, giving you continuous background ventilation without leaving your doors open.
