REDTRON DIY Window Screen with Zipper Opening (150cm x 180cm) – Black self-adhesive mesh

The essentials

If you want insect protection without taking your window fly screen down every time you want fresh air, a zipper opening is the kind of detail that actually matters. This REDTRON DIY window screen uses a fine mesh designed to help keep mosquitoes and other bugs out, while still letting air move through and maintaining an outside view.

On paper, it’s a straightforward “measure, cut, stick” solution: you confirm the window size and installation position, trim the mesh to fit, then apply the self-adhesive hook tape. It’s aimed at people who want something practical for everyday ventilation rather than a complicated installation.

Key features

The standout is the zipped opening design. There’s a 32 cm zipper opening in the netting, made so you can open and close your window more easily without removing the whole screen or lifting the edge. For many households, that’s the difference between a fly screen you’ll use consistently and one that stays half-installed.

It’s also adjustable in the sense that the mesh is cut-to-fit: the roll is 150cm x 180cm, and it’s described as suitable for windows of 150cm x 180cm or smaller. That gives you room to match the shape of your window once you’ve chosen where it will sit.

The mesh is paired with a strong self-adhesive hook tape. The description notes it holds the window netting well, and that if you remove the tape there should be no residue and no damage to your window frame.

What stands out in everyday use

The practical value here is pretty clear: you get a physical barrier that’s meant to keep insects out, while the fine mesh still allows air in and keeps the view unobstructed. That makes it more livable than thicker covers that can feel “blocky” or restrictive.

A quick micro-scenario: imagine you’re making breakfast, the kitchen window is slightly open, and you’re trying to avoid flies or mosquitoes getting in. With a zipped opening in the screen, you can ventilate without having to remove the whole mesh—zip, open your window, then close again once you’re done.

Where it might fall short

It’s a DIY, self-adhesive setup, so it’s not the same as a rigid, permanently framed fly screen. Depending on your window surface and how carefully you align the tape, you may find that the fit needs a bit of patience—especially if your window is an awkward shape.

Also, because the described suitability is for windows of 150cm x 180cm or smaller, it may simply not be the right scale for larger frames. If you’re not within that size band, you’ll have to look for a different approach rather than trying to force a cut that doesn’t really fit.

Should you buy it?

It makes sense if you want insect protection with a ventilation-friendly design, and you’re happy with a cut-to-size project. The 32 cm zipper opening is particularly useful if you regularly open and close the window and don’t want to remove or lift the screen each time.

You may want to skip it if your window is larger than the stated 150cm x 180cm limit, or if you prefer a fully fixed screen system rather than self-adhesive tape. It also might not be your best match if you’re expecting a completely “set and forget” install with no measuring and trimming involved.

If you do buy, double-check your window size and where the screen will be installed before cutting. That small step will save you a lot of hassle.
