Roller insect screens for windows
The roller screen is the one most windows want. The mesh winds onto a spring-loaded roller housed in a slim cassette at the head of the opening, and pulls down in front of the window. Let go and it returns on its own; stop it halfway and it stays there.
How it is built
The cassette and the side channels are powder-coated aluminium, in a colour matched to your joinery — anthracite and white are the usual choices, but the range follows the RAL chart. The mesh runs in the side channels, which is what keeps it in place when a window is open and the air moves through.
The roller is fitted with an adjustable spring. That single component decides whether a screen still works properly after three seasons: too weak and the mesh sags, too strong and the handle snaps back. Ours can be re-tensioned rather than replaced.
Choosing the mesh
- Standard grey. The general-purpose mesh, the most discreet from outside.
- High transparency. A finer thread and a more open weave, when the view is the reason you bought the house.
- High contrast. Easier to read through against strong backlight, useful on a south-facing window.
- Fine mesh. A tighter weave for the smallest insects.
- Anti-pollen. Filters a large part of airborne pollen, for hay fever sufferers.
Where it is not the right answer
On a French door or a wide sliding bay, a roller screen means winding a tall drop of mesh up and down every time you go out. For those openings a side-sliding screen is better, and past a certain size a motorised screen is better still.
