Short answer: solar screen is not a thicker insect screen — it is a denser weave of heavily PVC-coated fiberglass yarn, positioned by manufacturers for sun control: heat reduction, glare control, UV blocking and daytime privacy. The market is organized around two shading classes, commonly sold as 80% and 90%, names that come from manufacturer-stated shading figures for their own fabrics — Phifer’s SunTex 80 and SunTex 90 being the most cited examples. The 90% class is denser: more heat and glare control, less light and outward visibility. The category sits next to insect screening in roll format and installation, but the specification fields that decide the purchase are different.
| Comparison | Standard insect screen | Solar screen (80% class) | Solar screen (90% class) |
|---|---|---|---|
| Primary job | Insect exclusion | Heat, glare, UV control | Maximum heat and glare control |
| Weave | Open nominal counts (18×16, 18×14) | Dense, heavy vinyl coating | Densest, heaviest coating |
| Outward view | Clear | Reduced | Further reduced |
| Daytime privacy | Minimal | Moderate | High |
| Common formats | Rolls, same as fabrication needs | Rolls, comparable width ladder | Rolls, comparable width ladder |
What solar screening actually is
Solar screening is woven from vinyl-coated fiberglass yarns into a much denser, darker construction than insect screen. The standard reference for the family is ASTM D4028/D4028M — Standard Specification for Solar Screening Woven from Vinyl-Coated Fiber Glass Yarn — a separate product standard from the insect-screen specification D3656, which is worth knowing when a tender names one or the other.

Because the weave is dense, the fabric does what open insect mesh cannot: it intercepts a large share of solar energy before it enters the glass. Manufacturers position these fabrics for exterior shades, porches, patios, sun-exposed windows and screen rooms — and describe them as also excluding insects, since nothing small passes the dense weave.
What “80%” and “90%” mean — and what they do not
The percentage names are manufacturer shading figures for their own fabrics. Phifer describes its SunTex 80 and SunTex 90 fabrics with approximately 80% and 90% sun-control figures, and Super Solar Screening with up to 90% — those numbers belong to Phifer’s products and constructions.

The practical reading for a buyer:
- the percentage is a positioning class, not a universal measurement;
- actual heat, glare and UV performance for a specific fabric comes from that product’s data or agreed testing;
- two fabrics in the same class can differ in yarn, coating weight and openness — which is why the sample, not the number, closes the comparison.
Where solar screen is bought instead of insect screen
- Sun-exposed windows where heat and fading are the complaint and the customer wants to keep the window open;
- porches, patios and gazebos used during high-sun hours;
- west-facing facades in hot climates, where glare control drives the purchase;
- daytime privacy applications — the dense dark weave limits the view in from outside during the day;
- distributor ranges that already carry insect screen and add solar as the natural premium line.
Installation and fabrication are close to insect-screen practice — spline channels, roll format, same tool families — which is why screen contractors and fabricators add solar work without new equipment.
The fields that decide a solar-screen inquiry
| Field | Why it matters |
|---|---|
| Shading class (80% / 90%) | The first fork in the comparison; visibility trade-off follows it |
| Reference fabric | If replacing a branded fabric, name it — matching beats re-describing |
| Roll width | Solar rolls follow a width ladder like insect screen; width drives panel economics |
| Color | Charcoal and black dominate; stucco and gray exist in some ranges |
| Data requirements | Heat/glare/UV figures for the specific fabric, if the sale depends on them |
| Volume and destination | Commercial terms, packing and freight |
The roll-width guide covers how width classes map to panel programs; the quotation-comparison logic in how to compare screen mesh quotations applies unchanged to solar.
Quick FAQ
Does solar screen block UV?
Manufacturer materials for solar fabrics emphasize UV and heat reduction as the core benefit — Phifer positions its sun-control products around blocking heat and UV before they enter the glass. The specific UV figure for a specific fabric is product data; treat category-level percentages as positioning and confirm the number that matters to your sale.
Can solar screen replace insect screen?
In practice, the dense weave excludes insects, and manufacturers position solar screen as an insect-plus-sun product for shade applications. What it costs you is openness and view — so it substitutes where sun control is the priority, not where a clear view is the point.
Is solar screen the same as “privacy screen”?
They overlap: the 90% class delivers strong daytime privacy from the outside. But privacy mesh and solar mesh are positioned differently in catalogs, and the shading figure is the solar category’s defining spec. Buy by the fabric’s data, not the label on the category.
