French doors – double doors that open inwards or outwards – are a beautiful feature in many UK homes, from Victorian terraces to modern extensions. But they are also a major entry point for insects. A single‑leaf screen doesn’t work. The answer is a bi‑parting folding screen (concertina).
Why a Single Screen Fails for French Doors
A standard retractable screen mounted on one side only covers one door leaf. When you open the other door, insects fly straight in. A hinged screen on the outside is impractical – it blocks handles and looks ugly. You need a system that covers both doors simultaneously, with no centre post.
How Bi‑Parting Folding Screens Work
Two folding panels (concertina style) are mounted on the inside of the door frame – one on the left, one on the right. Each screen can be pulled toward the centre, and they meet in the middle with a magnetic or overlap seal. You can open one side or both. When completely open, both screens fold back to the sides, leaving the doorway entirely clear – no centre post, no obstruction.
This design works for both inward‑opening and outward‑opening French doors.
Mesh Material Choices
- PET polyester: Affordable, nearly invisible, good airflow. Suitable for low‑traffic French doors.
- 304 stainless steel: Recommended for high‑traffic doors, pet owners, or homes where children push against screens. Also best for coastal areas.
Frames are powder‑coated aluminium – white, grey, black, or wood grain to match your doors.
Installation Overview
Each folding screen mounts with top and bottom tracks. A low‑profile bottom rail (approx 5mm high) is required. For tiled floors or heritage homes, ask about our top‑hung hanging system that has no floor track at all – the screen hangs from an overhead rail and glides without touching the floor. This is ideal for listed buildings or where you want to preserve original floor tiles.
Installation requires a drill and spirit level, but it’s manageable for a confident DIYer. MBORMC provides detailed instructions and video support.
Cost Range (Custom)
Bi‑parting folding screens are priced by total width and height. Expect £300‑800 depending on mesh material and size. Request a free quote with your door dimensions.
