The mesh, more than the frame, determines how an insect screen performs. We examine the differences between fibreglass, polyester, pet mesh and pollen mesh in terms of visibility, durability, airflow and resistance to sea air.
When choosing an insect screen, the conversation is usually about frame colour and opening style, yet the part that makes the biggest difference in daily use is the mesh. The mesh determines how clearly you see the view, how much air comes in, how resistant the screen is to tearing and how it reacts to the sun. In this guide we compare the two most common materials, fibreglass and polyester, and briefly touch on special-purpose meshes.
Fibreglass Mesh
Fibreglass mesh is made by coating glass fibre yarns with PVC and weaving them. It is the most widely used material in the screen industry. It has a low tendency to stretch, so it stays smooth for a long time in taut frames. It is unaffected by moisture, does not rust and resists sea air. In grey or black, it is almost invisible when seen from outside.
The weakness of fibreglass is its limited resistance to sharp objects and claws; a hard knock or a cat’s scratching can tear the mesh. It can also leave marks at fold lines over time, so it is generally not used in pleated systems.
Polyester Mesh
Polyester mesh is woven from synthetic polyester yarns and is mostly used in pleated systems, because it can fold without creasing and holds its pleat shape well. Thanks to its flexibility it tolerates impacts better than fibreglass. Good-quality polyester meshes are made UV-resistant; cheap meshes without UV additives can stiffen and change colour within a few seasons on sunny facades.
The limitation of polyester is that it may stretch slightly over time when used under tension. For this reason, good-quality fibreglass often looks smooth for longer on large fixed screens.
Special-Purpose Meshes
- Pet mesh: Made of thick, PVC-coated polyester yarns; many times more resistant to scratching than standard meshes. Visibility is reduced somewhat.
- Pollen mesh: Very densely woven, it traps a large share of pollen and fine dust. Suitable for allergy sufferers, but airflow drops noticeably.
- Invisible (high-transparency) mesh: With finer yarns, this mesh interrupts the view the least; it is popular in homes with lake or sea views.
- Solar mesh: Blocks part of the solar radiation and reduces heat gain indoors; useful on west-facing facades.

Recommendations for Our Region
Around Ortaca, Dalyan and Köyceğiz, summers are long, hot and humid, and mosquito numbers are high because of the nearby lake and wetlands. In these conditions the following criteria matter when choosing a mesh:
- Meshes with openings fine enough for mosquitoes, with a weave density such as the standard 18x16,
- UV-resistant material on sunny facades,
- Fibreglass or PVC-coated meshes that resist moisture and salt in homes near the coast,
- Dark, high-transparency meshes on openings with a view.
Why Does Mesh Colour Matter?
Mesh colour is often seen as a purely aesthetic choice, yet it directly affects visibility. Dark meshes (black, anthracite, dark grey) reflect less light, so the view looks clearer and more vivid when seen from inside during the day. Light-coloured meshes (light grey, white) can shine in the sun, creating a slight haze effect, and are more noticeable from outside.
Even with white window frames, choosing a grey or black mesh usually gives better results; the frame matches the windows while the mesh almost disappears. This difference is especially noticeable in homes with lake or sea views.
Factors That Affect Mesh Lifespan
Whatever material is chosen, the life of the mesh depends on the conditions of use. West- and south-facing facades that receive direct sun for long periods age the mesh faster than north-facing ones. In homes near the coast, wind-blown sand particles can abrade the mesh surface. Stiff brushes and chemical cleaners damage the coating. Regular, gentle cleaning and keeping the mesh taut extend its service life whatever the material. A worn mesh can often be renewed without replacing the frame, which makes a screen an economical long-term investment.
If you cannot decide, the most practical method is to try mesh samples in front of your own window in daylight. The same mesh can look different under showroom lighting and on your home’s facade. This way you can judge both the transparency and the colour match with your own eyes and make a choice you are happy with.
Conclusion
Fibreglass mesh is a long-lasting, transparent choice for taut systems and humid, salty air. Polyester mesh is indispensable for pleated systems and stands out for its flexibility. If you have a cat, suffer from allergies or want to protect your view, special meshes come into play. During a free site survey our team shows you mesh samples on site to make your decision easier.
