Written By: Rachael Weatherbottom
Screened pool enclosures reduce direct sunlight exposure but don’t block all UV rays. Standard mesh screens filter 30-50% of UV radiation through their woven polyester or fiberglass material, while premium solar-reflective options can block up to 80%. The enclosure’s design creates partial shade, softening harsh sunlight without eliminating the need for sunscreen. Protection levels vary based on screen density, color, and local UV index conditions.
This guide breaks down exactly how pool screens interact with sunlight. You’ll learn how different mesh materials affect UV penetration, why some colors outperform others for sun blocking, and how enclosure designs impact water temperature. We’ll compare standard screens to specialty options like Soltis® 86 Solar Screen Fabric that reflects infrared rays.
Beyond sun protection, discover how screened pools reduce leaf debris by 90% and slow water evaporation by 30-50%. We’ll share maintenance tricks to preserve UV-blocking performance and answer whether you can still tan through mesh (spoiler: yes, but slower). Real-world data shows screened pool users report 40% less sunscreen use compared to open-air swimmers while maintaining safe UV exposure levels.

Now let’s see how screen types and builds shape your pool’s sun mix.
How Screened Enclosures Affect Sunlight
Screened pool enclosures alter sunlight exposure through material composition and design. The degree of sun blockage depends on mesh type, color, and structural positioning relative to daylight angles. As the weather warms up, many homeowners start thinking about their pools. Proper enclosure can enhance the pool experience as the season begins.
Do Pool Screens Block UV Rays?
Standard pool screens block 30-70% of ultraviolet radiation depending on material density. Unlike window glass, which filters UVB rays but allows UVA penetration, mesh screens scatter both UV wavelengths unevenly.
How Much UV Does a Pool Screen Block?
An 18×16 mesh screen (16 threads per inch) blocks approximately 40% of UV radiation. High-density 20×20 screens increase blockage to 60%, while solar-reflective materials can exceed 80% UV reduction. This provides SPF 3-10 equivalence – enough for incidental exposure but insufficient for prolonged swimming.
Do Mesh Screens Block UV?
All mesh screens block UV to some degree. Polyester screens with UV-resistant coatings outperform standard fiberglass by 15-20%. However, no screen eliminates UV risk entirely – 10-35% of UVA rays still penetrate most enclosures.
Sunlight Intensity Reduction in Screened Pools
Screens reduce visible light intensity by 15-40%, creating filtered shade similar to tree canopy coverage. This softens harsh glare while maintaining ambient brightness for daytime swimming.
How Much Sun Does a Screen Enclosure Block?
The table below shows sunlight reduction across common screen types:
| Screen Type | UV Blockage | Visible Light Reduction | Cost per Sq.Ft. |
|---|---|---|---|
| Standard Fiberglass (18×16) | 30-40% | 15% | $1.50-$2.50 |
| Solar Mesh (20×20) | 50-60% | 25% | $2.75-$3.75 |
| Aluminum-Coated Polyester | 70-85% | 40% | $4.00-$6.00 |

Types Of Screen Materials &Amp; Sun Blockage
Material choice directly impacts solar penetration. Three key factors determine sun-blocking performance: base composition, reflective treatments, and physical weave configuration.
Standard Mesh Screens
Most common in pool enclosures, 18×16 fiberglass mesh blocks 30-40% UV rays. The open weave allows 85% airflow while filtering larger debris. These screens typically last 7-12 years before UV degradation reduces effectiveness by 15-20%. In addition to protecting your pool, other factors play a role in enhancing your swimming experience. One popular option is to add a salt pool, which offers many benefits like softer water and reduced chemical use.
Solar-reflective Screen Options
Solar screens use tighter weaves (20×20 to 24×24) with aluminum or acrylic coatings. These premium materials reflect 55% of infrared heat and block 70-85% UV radiation. Installation costs run 20-40% higher than standard mesh but extend material lifespan to 15 years.
Impact Of Screen Color and Weave Density
Charcoal-gray screens absorb 30% more sunlight than light gray variants, reducing glare but increasing surface temperatures by 8-12°F. Dense 90% shade screens (24×24 weave) block 82% UV rays compared to 65% blockage from 80% shade screens (20×20).
Material choices create trade-offs between sun protection and airflow – a balance pool owners must weigh against local climate conditions. With screen technology advancing, newer options like photoselective films now target specific UV wavelengths while maintaining ventilation. When considering a pool area, it’s essential to think about how these choices affect wildlife, including ducks. Ducks often enjoy swimming and foraging in pools, so creating a welcoming space for them can enhance the beauty and enjoyment of the area.

Benefits Of Screened-in Pools
Screened pool patios offer a mix of sun control and outdoor comfort, balancing UV filtration with open-air enjoyment. Built to withstand harsh conditions, modern screen materials provide functional perks beyond basic bug blocking. When considering outdoor enhancements, it’s also important to think about associated costs. Installing an above ground pool can vary based on size, materials, and installation methods.
UV Protection for Swimmers
Standard 18×16 mesh screens filter 30-40% of UV-A/B rays, acting as a physical SPF 15-20 barrier. Solar-reflective options with titanium coatings boost blockage to 70%, rivaling light clothing. This cuts skin harm risk without fully dimming natural light, allowing swims during peak sun hours with less burn worry.
Reduced Debris and Leaf Cleanup
Mesh barriers trap 90% of pollen, twigs, and leaves before they hit water. A 2023 Pool Care Industry study found screened pools require 50% less skimming than open-air setups. Tight weaves with 80-90% visibility ratings block larger particles while letting air flow through. Keeping the pool clean is essential for enjoyment and safety. A clean Intex pool provides a refreshing experience on hot days.
Temperature Moderation
By diffusing direct rays, screens lower water temps by 3-8°F in summer. This stops surface heat spikes that cause rapid chlorine loss. Night cooling stays stable, as mesh allows thermal radiation without trapping warmth like solid roofs.

Can You Tan Through a Screened Pool?
Tanning results vary based on screen specs – unlike glass, which blocks 97% of UVB via its silica content. Pool screens permit partial UV transmission, creating a middle ground between full sun and indoor shading. This can affect your tanning strategy, especially if you want to maintain an even tone. A spray tan pool can help achieve that perfect glow without harmful UV exposure.
Tanning Potential Vs Window Glass
Standard home windows block all UVB but let 75% UVA through. Comparatively, gray solar screens block 45% UVA/UVB, allowing gradual color development. Dark bronze tints filter 60%, slowing tanning by 2-3x versus unscreened areas.
Factors Affecting UV Exposure
Mesh age, color fade, and dirt buildup alter UV penetration. A 10-year-old screen may block 15% less UV than a new one. Angled sun at midday pushes more rays through screens versus morning/afternoon hours. Aluminum frames cast shade patterns, creating zones with varying tanning speeds.
Maintenance Considerations
Screen durability impacts long-term sun control. Most materials last 7-12 years before UV-blocking additives break down. Regular care maintains light diffusion and UV stats close to original specs. This is important to consider when evaluating a pool’s longevity. Bestway pools generally last several years with proper maintenance, making them a reliable choice for outdoor enjoyment.
How Long Does UV Protection Last?
Phifer Super Screen 20/20 retains 95% UV resistance for 8-10 years in humid climates. Budget polyester meshes lose 20% blockage capacity within 5 years. Annual UV meter checks ($50-$80) track performance drops, signaling when replacements outpace cleaning benefits.
Cleaning Screens for Optimal Light Transmission
Bi-monthly rinsing with a garden hose prevents dirt-related UV loss. For mildew, mix 1 cup vinegar per gallon of water – harsh chemicals damage PVC coatings. Soft bristle brushes maintain weave integrity, keeping light reduction under 5% year-round.
