Motorized Screen Fabric & Mesh Guide
The system is the same at every opening. The fabric is what changes, and it is where most of the decisions that matter actually get made.
Five Categories, Doing Genuinely Different Jobs
People often talk about "screens" as one thing. Manufacturers do not — they publish separate categories because the materials are engineered for different outcomes, and one will not do another's job well.
What follows describes each category and what it is chosen for. It deliberately contains no openness percentages, no UV-block figures and no exclusion rates, because those numbers belong to the fabric manufacturer, differ by product and color, and change. We bring current manufacturer data to the consultation and specify against it.
What Each Material Is Actually For
Solar mesh
An open weave chosen for light control. It intercepts direct sun and glare before it enters the space while keeping a usable view through it. Chosen where the complaint is heat and washed-out light. Not designed to exclude insects.
Insect mesh
A tighter weave chosen for aperture. The opening in the weave has to be smaller than the insect being excluded, while still letting air move. Chosen where the complaint is mosquitoes and the evening. Does relatively little for heat.
Privacy weave
A denser fabric chosen to reduce how much detail is legible through it. Still woven, still breathes, still not a wall. Performance depends heavily on which side is brighter, which is why it behaves differently after dark.
Clear vinyl
Not a mesh at all — a flexible clear panel. Chosen where the opening needs to be genuinely closed against wind-driven rain and cold air while staying visually open. Stops airflow, so it is a weather-side material rather than a summer one.
Storm-specific fabrics
Storm protection is a separate product and specification class with its own structural and product requirements. These materials are not an upgrade to an everyday screen and should not be treated as interchangeable with one — see storm protection screens.
Openness Factor, and Why We Will Not Quote One
The shade industry commonly uses "openness factor" to describe roughly what proportion of a woven fabric is open space rather than yarn. Lower means tighter and darker; higher means more open and more view.
Two cautions. It is an industry convention rather than a standards-body definition, so it is not something you can rely on to compare products from different makers on equal terms. And fabric product names frequently contain numbers that are not openness figures — they are the manufacturer's model designations. Converting a product name into a performance percentage is a common mistake, and not one we will make on this site.
Where insect exclusion is concerned there is at least a physical anchor. The US Environmental Protection Agency publishes reference body widths for common insects — around 0.078 in. for the Asian tiger mosquito and about 0.059 in. for biting midges — in a document written for water-tank screening. Those dimensions explain why aperture matters and why a no-see-um problem needs a finer mesh than a mosquito problem. They are not a patio screening recommendation, and we do not present them as one.
What we will do at specification: put the manufacturer's current data sheet for the actual fabric in front of you, in the color you are choosing, and explain what the figures on it mean. What we will not do is publish those numbers here where they will go out of date and get quoted back at us.
Four Questions That Decide the Fabric
Which direction does the opening face? A west elevation takes low afternoon sun and often wants a solar weave. A shaded north opening is less often a heat problem and more often an insect question.
What is the actual complaint? Heat, insects, sightlines or weather. Each points to a different category, and it is worth being honest about which one drives you indoors first.
What is on the other side? A view worth keeping argues for openness. A fence line does not. Color matters here too — darker fabrics generally read as more transparent from inside, lighter ones reflect more but can glare.
When do you use the space? A patio used at midday and one used after dark want different things, particularly where privacy is concerned.
Openings on the same patio routinely end up with different answers. Solar, insect, privacy and weather protection can often be configured within a coordinated motorized screen system; storm protection is a separate product and specification class with its own structural and product requirements. Configuring the everyday layers together is the whole idea behind the four-layer approach.

Fabric FAQ
Can one fabric do everything?
No. A weave open enough to keep a view will not exclude mosquitoes, and a weave tight enough to exclude them costs you light and airflow. That is why we specify per opening rather than per patio.
Which color should I choose?
Darker fabrics generally give a clearer view out and less internal glare; lighter fabrics reflect more heat but can be brighter to look at. Frame and fabric color may also be relevant to an architectural review submission — in The Woodlands, see the design review guide.
Can I change the fabric later?
Refabrication of an existing screen is sometimes possible, and it is a manufacturer question rather than a general one. It is much cheaper to get the choice right at specification, which is why we push for sample review on site.
How long does screen fabric last?
Exterior fabrics are made for sustained sun exposure and the manufacturer publishes warranty terms for them. We go through the current terms and care requirements before you order rather than summarizing them here, because they differ by material.
Is there a standard for insect screening?
ASTM publishes a specification covering insect screening and louver cloth woven from vinyl-coated glass yarns, so the category is formally recognized. We have not reproduced its contents here, and we would not quote a standard we have not read in full.
Judge Fabric in the Space, Not on a Screen
Samples held up in the actual opening, at the time of day you use it, settle this faster than any specification sheet.
