Fly Screen for a Patio Door: Measure Before You Choose
Updated: 15.10.2026
You step through the patio door with a tray, and the midges follow you in. A fly screen for a patio door has to close again after that walk-through, while a window sheet stays a panel you hold aside. The comparison's top pick and best value are window sheets, and both are the wrong product once people walk through. This guide is from the Products Compared editorial team. It uses three amazon.co.uk door listings captured on 15 October 2026, with no laboratory test of the mesh. A commission on our links does not change what you pay. Window kits sit on the [insect screen comparison](/hub/garden-supplies/windhager-insect-screen).

A sheet is the wrong product
A patio door you walk through needs a swinging leaf, or a frame you cut and then pass. A peel-off net has no hinge and no floor brush.
Three door listings are in this capture. B09JLFYYZ9 is the fixed swing door, B01CYIWNQ4 is the aluminium kit titled Rhino with Windhager in the brand field, and B00V0H8UMC is the Expert clamp door. Leave window sheets on the fly screen buying guide. Only 100 by 210 centimetres puts the ready-made swing size in play.
The 100 x 210 cm swing door
B09JLFYYZ9 is a swing screen door of 100 x 210 cm. On 15 October 2026 it was about £155.36. It opens both ways, with magnets and Velcro or screws. The item type also says clamping frame.
Use it when the opening is already that size. None of the 50 review blocks were from the United Kingdom. The swing door is the fixed-size choice only.
Two kits you shorten yourself
B01CYIWNQ4 was about £63.64, titled Rhino, with Windhager as the brand, model 03758, and 04311 also in the item type. Mesh of 1.26 x 1.44 mm is printed only here, as a hole size, and it is not a midge test. Of 50 review blocks, 26 were from the UK and mention broken corners, short mesh and missing parts.
B00V0H8UMC, model 03903, was about £80.56 at 3.09 kg, with a 16 mm figure and adjustable hinges. Only 3 of 50 review blocks were from the UK. On exterior uPVC the handle hit the mesh: a 60 x 30 mm packer left a gap insects can use. The Rhino-title kit has more UK review text. If 03758 and 04311 still disagree, order the ASIN you opened.
Before you cut or screw
Open the carton before you mark a cut. UK notes on both kits mention missing parts, and a short rail cannot be restored. Stop if a corner, a screw or the brush is absent, and stop again if the opening is out of square.
If cutting worries you, or rented uPVC must not be drilled, leave the screws packed. Use the how to fit a fly screen page for clear size, reveal and handle clearance. The mesh is not the guarding in Approved Document K. That document is England's guidance on falling, collision and impact, and not the building regulation in Scotland, Wales or Northern Ireland. On a balcony, fit the screen only where a real barrier already covers the drop.
Common questions
Will a window net work on a patio door?
A window net will not serve as a fly screen for a patio door you walk through. It has no hinge and no floor brush, so you hold the mesh aside on every trip. Use a swinging leaf, or a frame you cut to the opening. Match the 100 x 210 cm swing door only when the opening is that size.
Does the swing door fit every UK patio door?
B09JLFYYZ9, model 03241, is 100 x 210 cm, about £155.36 and 4.2 kg in the 15 October 2026 capture, opening both ways with a foot tread, magnets, and Velcro or screws. The item type also says clamping frame. It suits that one opening size. A wider, narrower or shorter UK patio door needs a kit you shorten. None of the 50 review blocks were from the UK.
What is the difference between the £63.64 kit and the £80.56 kit?
B01CYIWNQ4 at about £63.64 is aluminium, 2.04 kg, with self-closing hinges, a brush, and mesh of 1.26 x 1.44 mm on that page only. The title says Rhino, model 03758, and the item type also cites 04311. B00V0H8UMC at about £80.56 is the Expert, model 03903, at 3.09 kg, with clamp or glue and a 16 mm figure. UK review blocks were 26 of 50 against 3 of 50. The mesh figure is not a midge test.
What if the existing door handle hits the mesh?
A UK review of B00V0H8UMC describes an exterior uPVC door where the handle hit the mesh. A 60 x 30 mm packer left a gap, and the same notes mention soft screws and missing parts. A gap you build in so the handle can turn is a gap insects use. Measure the projection before you cut. Daylight at the handle means this kit is the wrong shape for that door.
Is the screen child-safe on a balcony?
Use the screen as an insect barrier, and keep the drop as a separate question. Windhager's FAQ covers children, fall protection and fitting location. Approved Document K deals with falling, collision and impact for building work in England, and a mesh is not that guarding. That document is not the building regulation in Scotland, Wales or Northern Ireland. Fit a proper barrier before you rely on the screen at a balcony.
Why do the title and the model field disagree?
On B01CYIWNQ4 the title says Rhino, the brand says Windhager, the model says 03758, and the item type also cites 04311. On B09JLFYYZ9 the model is 03241 and the item type also says clamping frame. Those pairs are amazon.co.uk fields from 15 October 2026, and this page does not choose a winner between them. Order the ASIN you checked, then reread the model line if the listing has changed.
