Technical specifications of our fly screens

At Moskera we don't just fight insects: we install peace and quiet. And it all starts with the mesh, the heart of a fly screen. It is the mesh that stops what you don't want while letting air, light and the view through. Here, in full transparency, is what it is made of.

The same premium mesh goes into all three models (door, large opening and window): a PVC-coated E-glass fibreglass fabric, tightly woven, with flame-retardant filaments.

Technical specifications of the mesh

From the most important to the most secondary, here is the full spec sheet of our fabric.

Specification Value What it changes for you
Mesh density 18 × 16 threads per inch (per 2.54 cm) A tight weave, the reference standard: the right balance between protection, air and light.
Hole size ≈ 1.1 to 1.5 mm Fine enough to block common flying insects, open enough to breathe.
Insects stopped Mosquitoes, flies, wasps, hornets, bees, moths, large spiders A genuine mechanical barrier, with no chemicals at all.
Material PVC-coated E-glass fibreglass The strength of glass with the flexible protection of PVC: durable and stable.
Filament treatment Flame-retardant (M2 fire rating) The mesh slows the flame and does not catch alight like an ordinary textile.
Colour Black, light grey or white Black absorbs light: the most transparent and most discreet mesh. White reflects it: more opaque, more privacy.
Visibility outwards Black ≈ 90 to 95 % · Light grey ≈ 75 to 85 % · White ≈ 60 to 75 % With the black mesh the view stays almost unobstructed. Light grey comes close; white preserves more privacy.
Air and light ≈ 59 % open area (≈ 65 % of the airflow preserved) The room stays cool, ventilated and bright.
UV resistance Anti-UV, S1 rating It does not yellow or grow brittle in the sun, year after year.
Durability Does not rust, rot-proof, keeps its shape Ideal outdoors, in the rain and by the sea alike.
Mechanical strength 90 to 2000 daN / 5 cm A tough fabric that will not tear in use.
Fabric weight 122 g/m² A dense, quality mesh, not a bargain-bin fabric.
Glass thread diameter 0.02 mm A fine, discreet thread, but tightly woven for strength.
Standards and certifications ISO 9001:2015, NF EN 13561, M2 fire, anti-UV S1 Controlled quality, compliant with manufacturing standards.
Safety Non-toxic, insecticide-free Safe for children and pets alike. Meow. Woof.
Care Sponge or damp cloth (no washing machine, no abrasives) A wipe with a sponge and it is clean: no hassle.
Fitting No drilling, no screws (magnetic system and self-adhesive hook-and-loop) Fitted in around 10 minutes, without damaging your walls or joinery.
Service life 8 to 20 years A purchase that lasts: peace and quiet for the long run.
Worth knowing: for the vast majority of homes, 18 × 16 remains the best compromise between protection and comfort.

One mesh, three formats

Whichever model you choose, you get the same PVC-coated fibreglass fabric, flame-retardant and tear-proof. What changes is the format and the use.

Door model

For front, garage and back doors. A central magnetic opening that closes itself behind you.

Door size guide

Large opening model

For sliding glass doors, patio doors and wide openings. Designed to cover the most generous openings.

Large size guide

Window model

For all your windows. Fitted without drilling, ideal whether you rent or own.

Why E-glass fibreglass?

  • Against aluminium: it does not rust, does not dent, does not hold creases, and stays flexible (perfect for a magnetic system).
  • Against bare fibreglass: the PVC coating locks the weave, protects the thread, stabilises the colour and makes cleaning easier.
  • Against polyester: it is more stable in heat, does not slacken, and has a non-combustible glass core.

Frequently asked questions about the mesh

Which insects does an 18 × 16 mesh stop?

Mosquitoes, flies, wasps, hornets, bees, moths and large spiders. 18 × 16 remains the ideal standard for the vast majority of homes.

Does the mesh let air and light through properly?

Yes. About 59 % of the surface is open, preserving close to 65 % of the airflow. The room stays cool, airy and bright.

Which mesh colour should I choose?

Black absorbs light instead of reflecting it: it is the most transparent mesh, with about 90 to 95 % visibility to the outside, less glare, and it stays discreet seen from outside. Light grey comes close behind (about 75 to 85 %). White is the most opaque (about 60 to 75 %) and preserves more privacy during the day.

Does the mesh rust or lose its shape over time?

No. Fibreglass does not rust, does not corrode, is rot-proof and keeps its shape, unlike aluminium, which dents and holds creases.

Is the mesh fire resistant?

Yes. Its filaments are flame-retardant and the fabric is rated M2 (hard to ignite): it slows the flame and does not catch alight like an ordinary textile.

How do I clean the fly screen?

A wipe with a sponge or a damp cloth is enough. Avoid the washing machine and abrasive products, which damage the PVC coating.

Is it safe for children and pets?

Yes. The mesh is non-toxic, flexible (no sharp metal edges) and works as a mechanical barrier: no insecticide, no chemicals.

How long does the mesh last?

From 8 to 20 years depending on use: anti-UV coating, stable and hard-wearing fibreglass. A purchase that lasts.
