tesa fly screen buying guide

Updated: October 2026

You are at a uPVC window with a tape measure, and tesa Insect Stop puts a 100 cm square beside a much taller sheet. The mistake is ordering mesh the same size as the frame, or a magnetic door curtain for a window you only trim. This tesa fly screen buying guide is the order: line, size, tape, colour, then one sheet or a pack of three. Shelf prices and star lines are the amazon.co.uk figures on our [tesa fly screen](/hub/hedges-and-privacy-screens/tesa-fly-screen) comparison. The Products Compared editorial team did not laboratory-test these sheets. A qualifying purchase can earn us a commission at no extra cost to you.

Which tesa line is for a window

A window you open on warm evenings takes a Standard sheet: mesh plus hook-and-loop, trimmed and washed at up to 30°C. Comfort is the easy-off version. The 120 cm x 240 cm Comfort is the French-window sheet at £9.51. Open/Close, 130 cm x 150 cm at £23.99, rolls aside when you use the handle every day. A door you walk through takes the magnetic curtain, which you must not cut. Who should open which listing is on best tesa Insect Stop, and fitting is on how to fit a tesa fly screen.

Buy larger than the frame

Measure width and height in more than one place, and buy a sheet larger than the biggest reading. Reviews on the anthracite 100 cm sheet, £2.56 and 4.2 from 4,396 reviews, say that size often comes up short. Step up to 110 cm x 130 cm, such as the anthracite Standard at £6.97, or to 130 cm x 150 cm. The white sheet of that larger cut is £7.20 and is the best value here for one ordinary window. The tall Comfort listing does not state cut-to-size, so do not hack it down to a small casement.

Tape length is a second measurement

The strip in the box is a different budget from the area of the mesh. Standard listings here are one net plus one hook-and-loop strip set. Reviews on the white 130 cm x 150 cm sheet, and on the anthracite sheet of that size, say the tape ran out when one sheet was split across two windows. A 90 cm by 80 cm frame needs roughly 3.4 metres of strip to go round once. That figure is geometry, not a length on the box. An overlap is a lump, and that corner lifts. Two windows need two strip sets, even when one sheet has enough fabric.

Anthracite, white, or a pack of three

Anthracite is the less obvious mesh. White is sold as light privacy, a colour name, not a blackout blind. Streme’s UK guide says white mesh shows like a net curtain. None of these tesa listings states a midge grade. The white three-pack of 110 cm x 130 cm sheets is £13.31 in the saved listing. The anthracite three-pack is £13.40 in that file. A spot check on 15 October 2026 put that listing near £14.19. Both packs print 3,690 reviews, so the figure is one line shown twice. The door rule is on window sheet or magnetic door curtain.

Which order to follow

If you only tilt a window now and then, buy a Standard sheet larger than the frame and a strip that goes round once. If you peel the mesh most days, Comfort or Open/Close is the line, not a bigger Standard sheet. If you walk through the opening, stop at the magnetic curtain and do not cut it.

Common questions

What size tesa fly screen do I need for a one-metre window?
Buy larger than the frame, not a 100 cm square. Reviews on the anthracite 100 cm sheet say that size often comes up short once the mesh is tensioned. A 110 cm x 130 cm sheet, or a 130 cm x 150 cm sheet, is the usual step up. Measure in more than one place, because a uPVC frame is rarely one exact rectangle.
Is anthracite or white easier to see through?
Anthracite is the less obvious mesh from outside. White is labelled light privacy on several listings, which is a colour name, not a blind. Streme notes that white mesh shows like a net curtain. Neither colour is a midge screen, and these tesa sheets do not state that finer grade. Two three-packs say Clear in the colour field while the titles say white or anthracite.
Does a three-pack include enough tape for three windows?
The titles say three nets, and the included lines say the screens come with self-adhesive tape. The components field on both three-packs says masking tape, so confirm real hook-and-loop sets in the parcel. A single Standard sheet is one net and one strip set, and reviews say that set runs out when a sheet is split across two windows.
Is the white sheet a privacy blind?
No. Light privacy is the colour name on white listings such as the 100 cm square and the 130 cm x 150 cm sheet. It is not blackout fabric and not a stated light-blocking percentage. You still see a pale mesh, closer to a net curtain than to anthracite.
Will a Standard sheet stop midges?
Not on any claim printed for these listings. Streme separates ordinary insect mesh from a finer midge grade, and these Standard and Comfort pages do not state that grade. Buyers describe fewer flies, wasps, moths, and spiders. They do not give you a hole size you can quote. If you need a stated midge screen, this range is the wrong product.
