Bifold fly screen doors with pleated grey mesh and a white aluminium frame. Top and bottom tracking for maximum insect protection while letting light and air through.
At £600 to £900, this is the most considered purchase we sell. The customers who choose it are usually building or renovating, often spending five or six figures on the doors themselves, and want fly protection that matches the quality of what they've installed. The aluminium frame complements modern bi-fold finishes, the pleated mesh is barely visible when extended, and the whole assembly sits in its own track so the bi-fold doors keep their full operating range.
A bi-fold flyscreen is the right choice when a magnetic or folding screen can't span the opening. The adjustable magnetic screen stops at 200cm wide; the single folding door stops at 105cm. Anything wider, and the bi-fold is the only option in the catalogue that maintains a clean, framed look. Single goes up to 400cm; double up to 800cm.
The frame is white aluminium, the mesh is pleated and runs in a top and bottom track, and the cassette is engineered to slide cleanly for years of daily use. Every screen is dispatched by courier in two to three working days, fully assembled with fixing hardware included. If you'd like the screen cut to a non-standard size before dispatch, we can do that with a one week turnaround for an extra £60 on the single or £80 on the double.

What Are They?
Bifold fly screen doors - also called bi-fold flyscreens or pleated insect screens. Stylish white aluminium frames with tightly pleated grey mesh that runs in a top and bottom track. The mesh pulls smoothly across the opening to keep flies, wasps and other insects out while letting light and ventilation through.
The single 400 × 235cm mounts on the left or right and pulls across the full opening. The double 800 × 235cm uses two cassettes - one on each side - and the screens meet and magnetise shut in the middle.
Sizes & Pricing
- Single 400 (wide) × 235cm (high) - £599.99 including UK mainland delivery
- Double 800 (wide) × 235cm (high) - £899.99 including UK mainland delivery
Cut to size: we can resize before dispatch with a one-week turnaround - £60 on the single, £80 on the double.
Easy to Use?
Pull the handle and slide the screen across the opening. On the double model the two screens meet in the middle and magnetise shut. Release the magnetic catch and the screens fold neatly back into their cassettes when not in use.
