How do bespoke fly screens differ between French doors and sliding patio doors?

Fly screens for French doors typically use a dual-cassette central magnetic closing system that mounts opposite the door swing (internally for outward opening doors, or externally for inward doors) with an ultra-slim 3mm threshold. In contrast, fly screens for sliding patio doors use large single-span lateral pleated mesh systems or dedicated parallel sliding tracks engineered with heavy-duty tension cords to span expansive glass widths up to 6 metres.
Key Engineering Characteristics:
  • Opening Direction: French door screens feature twin side cassettes meeting in the middle with a magnetic seal; sliding door screens pull across the active sliding pane.
  • Span Capacity:
    French door screens cover standard 1.2m–2.4m double openings, while sliding patio screens support massive openings up to 6.0m with zero centre sagging.
  • Mounting Clearance: French door screens must fit opposite the door handle swing; sliding door screens mount directly onto the outer frame without obstructing sliding tracks.
  • Threshold Profiles: Both systems utilize ultra-low 3mm caterpillar floor guides ensuring zero trip hazards and 100% wheelchair / pram accessibility.

How Bespoke Fly Screens for French Doors Work?

Bespoke fly screens for French doors are custom-fabricated with a dual-part meeting system. A slim powder-coated aluminium cassette is mounted on each side jamb of the doorway reveal. When drawn together, both pleated mesh wings latch securely in the centre via a full-length magnetic strip.
Opposite-Swing Fitment
Fitted internally for outward-opening French doors, or externally for inward-opening doors, ensuring 100% handle clearance.
Single or Double Door Flexibility
Open just the primary active door for quick access, or open both doors for full garden parties.
Ultra-Low 3mm Floor Guide
Flat caterpillar track ensures flush thresholds without tripping children or snagging pram wheels.

How Bespoke Fly Screens for French Doors Work?

Sliding patio doors feature large, continuous panes of glass (often spanning 2 to 6 metres wide). A bespoke patio door screen uses a single-span lateral pleated glide system with heavy-duty Kevlar tension cords running horizontally through the mesh folds.
The screen parks discreetly against the wall jamb or fixed glass mullion in a slim 45mm housing. When you slide the glass patio door open, you simply pull the screen across to cover the active walk-through area. The internal tension cords prevent the mesh from sagging, flapping in coastal gusts, or popping out of top and bottom tracks.

Architectural Comparison

Door Swing Action vs Lateral Slide Clearance
French doors swing through a 90°–180° arc with projecting lever handles, requiring the screen to sit on the opposite frame face. Sliding patio doors move on parallel tracks, allowing the screen to fit flush on the doorway reveal with zero physical handle interference.
Span Width & Tension Reinforcement
Open just the primary active door for quick access, or open both doors for full garden parties.
Zero-Trip Thresholds & Accessibility
Flat caterpillar track ensures flush thresholds without tripping children or snagging pram wheels.
High-Density Mesh & Cross-Ventilation Airflow
Our bespoke pleated polyester mesh blocks 99.8% of UK flying pests while allowing unobstructed fresh garden airflow. The pleated design also provides optical visibility to prevent birds and pets from walking into the screen.

Frequently Asked Questions (FAQ)

Installation
Yes, bespoke fly screens for outward-opening French doors are installed internally within the doorway reveal or face-mounted to the interior frame. This ensures you can push both French doors open into the garden while the fly screen remains closed inside, keeping flies, wasps, and mosquitoes out.

Usage
For sliding patio doors, Cross Blinds & Shutters installs custom-measured single or dual lateral pleated screens with reinforced tension cords. The screen stays neatly parked beside the fixed glass pane and glides smoothly across the active sliding opening whenever the door is opened.

Safety
No. Cross Blinds & Shutters uses an ultra-slim 3mm floor track with a smooth caterpillar link chain. The threshold sits virtually flat against your existing patio sill or flooring, ensuring complete wheelchair, pram, and barefoot safety with zero trip hazards.

Insulation
Yes! Our bespoke French door fly screens feature independent twin cassettes meeting at a central magnetic strip. You can leave one screen docked in its cassette and slide the other to the middle, or open both fully for a wide panoramic garden walkway.

Motorisation
Yes. Cross Blinds & Shutters provides high-density woven polyester and pet-resistant reinforced mesh options. The pleated concertina structure absorbs light impacts from dogs and cats, popping back into place without tearing or stretching out of shape.
