Reflect more sun.
Reduce more heat gain.

SunShield Pro is a solar-reflective acrylic coating for exterior walls and roofs — third-party tested at SRI 102, with 0.82 solar reflectance and 0.86 thermal emittance. Measured performance most exterior paints simply don’t publish.

One coating. Three kinds of buyer.

Whether you live in the house, build it, or specify it, SunShield Pro is engineered around measured solar performance.

Tested performance

Three numbers that define a cool surface.

The most objective way to compare cooling coatings is measured radiative properties. Here are SunShield Pro’s third-party tested values, in plain English.

102
Solar Reflectance Index
A single combined “coolness” score. It tells you how hot a surface gets in full sun — higher is better, and the industry uses it to compare products fairly.
0.82
Solar Reflectance
The share of solar energy the surface bounces back instead of absorbing. More reflection means less heat soaking into the surface.
0.86
Thermal Emittance
How efficiently the surface releases the heat it does absorb. High emittance helps the surface shed heat rather than hold it.

For reference, California Title 24 Part 6 requires aged SR ≥ 0.63, TE ≥ 0.75, or SRI ≥ 75 for low-slope roofs in regulated climate zones. SunShield Pro’s initial values exceed these thresholds. Real-world results always vary by climate, exposure, texture, color and installation.

Why it’s different

Most exterior paint isn’t built for solar performance.

Premium exterior paint protects color and stands up to weather. That’s a different job.

Standard exterior paint

Engineered for color & weather

Great at hide, adhesion and durability. But the technical data sheet usually has no solar reflectance, no thermal emittance, no SRI — because cooling isn’t what it’s designed to do.

SunShield Pro

Engineered for measured solar performance

Formulated and third-party tested against the radiative metrics that define cool wall and cool roof performance: reflectance, emittance, and SRI — all published.

If a gallon of exterior paint doesn’t list these numbers, it isn’t a cool wall or cool roof product — regardless of marketing language around “reflective” pigments or “cool” color collections. Those are excellent paints for what they do. SunShield Pro is simply a different category.
Where it works

Proven across real-world surfaces.

Recommended for exterior stucco, concrete and masonry walls, plus a wide range of roof substrates — especially sun-exposed elevations.

How it works

The science, in three steps.

Sun-exposed surfaces absorb solar energy that moves into the building envelope. Reflectance and emittance work together to reduce that heat gain.

1

Sunlight hits the surface

Sun-exposed walls and roofs are constantly loaded with solar energy through the day.

2

The coating reflects more energy

High solar reflectance (0.82) sends most of that solar energy back instead of absorbing it into the surface.

3

Heat is released, not stored

High thermal emittance (0.86) helps the surface shed the heat it does absorb — so less heat moves into the building envelope.

Color options

Not just a white roof coating.

SunShield Pro uses its own color names and is available in multiple shades. Custom colors are available for bulk orders.

Performance note: Darker colors usually reflect less solar energy than lighter colors. For maximum cooling performance, choose lighter shades — and always test a sample on the actual surface, since screens emit light while paint reflects it.

Coverage depends on porosity, texture, and the film build needed to achieve uniform hide and performance. Plan a small test area on highly absorbent surfaces.

Enter your surface area and texture to get an estimate of gallons and 5‑gallon pails for your project. Coverage estimates use the published SunShield Pro data.

Most projects use 1 coat. Choose 2 for highly porous surfaces, dark substrates, or maximum hide.

Standards & documentation

Measured performance. Not just reflective language.

SunShield Pro’s radiative values are third-party tested and rated EXCELLENT against recognized ASTM methods:

  • ASTM C1549 — solar reflectance, portable reflectometer
  • ASTM C1371 — emittance using portable emissometers
  • ASTM E1980 — calculating Solar Reflectance Index (SRI)
For project documentation — permits, rebates, Title 24 submittals or LEED credit — confirm requirements against the latest available manufacturer documents (TDS / SDS in production).

Questions

Frequently asked.

Short, factual answers for homeowners, builders and specifiers.

A water-based, 100% acrylic solar-reflective coating for exterior walls and roofs. It is engineered and tested for cool-wall and cool-roof performance on sun-exposed surfaces — not as a substitute for standard exterior paint.
Standard exterior paints are built for color, hide, adhesion and weather durability. They generally do not publish solar reflectance, thermal emittance or SRI. SunShield Pro publishes all three because measured solar performance is what it is engineered for. It is a different product category.
Solar Reflectance Index combines solar reflectance and thermal emittance into one number used to compare how cool a surface runs in the sun. Higher is better. SunShield Pro’s tested SRI is 102.
Reflectance controls how much solar energy the surface sends back instead of absorbing. Emittance controls how efficiently the surface releases the heat it does absorb. Together they reduce heat gain compared with lower-performing coatings.
Yes. It is recommended for light-texture and heavy stucco, as well as concrete and masonry walls. Coverage varies with texture and porosity.
Yes. It is rated for low-slope and flat roofs, metal roofs, modified bitumen / built-up roofing (BUR), spray polyurethane foam (SPF) and concrete decks.
Yes. Reducing solar heat gain on a mobile home roof is one of the highest-value uses, since mobile homes typically have minimal roof insulation. Follow standard surface prep for the specific substrate.
Yes. It is a common choice for warehouses, metal buildings and light commercial structures, and for projects requiring Title 24 compliance or cool roof documentation.
No. High reflectance and emittance can reduce heat gain, but actual results vary by climate, building design, insulation, HVAC efficiency, orientation, surface texture, color and installation quality.
Yes. It is intended for spray or roll application and is water-based for easy water cleanup.
Interior walls (it is exterior only), vinyl or wood siding, and projects where appearance is the primary goal — a standard premium exterior paint is a better choice there.
Typically yes. Darker colors usually reflect less solar energy than lighter colors. For maximum cooling performance, choose lighter shades and test a sample on the actual surface.
The manufacturer states it meets California Title 24 cool roof thresholds for low-slope roofs, and the tested values exceed the aged SR / TE / SRI alternatives. For a project submittal, confirm with the most current manufacturer documentation.
