EnduRE30C ValueShield — Steel Roofing
EnduRE30C ValueShield is a rare-earth enhanced Passive Daytime Radiative Cooling (PDRC) coating engineered as a simplified two-layer system focused on pure reflective thermal performance. Designed for Colorbond steel and steel sheet roofing where heat reduction is the primary requirement — and waterproofing or hydrophobic functionality is not critical — ValueShield delivers the same rare earth radiative cooling mechanism as the broader EnduRE30C range at a more accessible price point.
By removing the waterproofing and hydrophobic layers from the system, ValueShield reduces material cost and application complexity without compromising core PDRC thermal performance — making it the practical choice for large-area steel roofing projects on a constrained budget.
EnduRE30C ValueShield works through two complementary mechanisms:
1. High Solar Reflectance — Reflects solar energy across the full spectrum, blocking UV and infrared radiation before it heats the steel surface.
2. Infrared Atmospheric Window Emission — Rare earth compounds actively re-radiate absorbed heat through the 8–13 µm atmospheric window directly to the cold sky, even during peak daytime hours.
Best For
- Colorbond® steel roofing — residential, commercial, and light industrial
- Steel sheet roofing where heat reduction is required but waterproofing is not critical
- Large-area steel roofs where cost efficiency and fast deployment are priorities
- Warehouses, sheds, farm buildings, and rural structures
- Animal barns and livestock shelters where air conditioning is not practical
- New builds or re-roof projects specifying PDRC performance within a constrained budget
Key Benefits

- Typically 25–40% reduction in cooling load (project dependent)
- Same rare earth PDRC technology as the full EnduRE30C range
- Simplified two-layer system — no waterproofing or hydrophobic layer required
- Lower cost than waterproofing-grade EnduRE30C systems
- Direct-to-steel application — fast deployment on large-area roofing

- Water-based, low VOC — safe for occupied buildings during application
- Coverage: approximately 50 m² per set
- Available in white and custom colours including Arctic Mist, Silver Cloud, Graphite Grey, Red Earth, Stone Bark, and Midnight Charcoal
ValueShield vs Gen 5 Metal vs Gen 7 — Which to Specify?
All three products deliver rare earth PDRC performance on metal and steel substrates. The right choice depends on budget, functional requirements, and service life:
- ValueShield — Simplified two-layer system, pure reflective thermal performance. No waterproofing or hydrophobic functionality. Best for dry climate applications and budget-conscious projects where heat reduction alone is the goal.
- Gen 5 — Metal — Silicone-acrylic three-layer system with rust-inhibitive epoxy primer and hydrophobic topcoat. Higher durability, broader substrate compatibility including galvanised and zinc-alum steel.
- Gen 7 — Fluorocarbon (PVDF-based) premium three-layer system. Highest SRI in the range, oleophobic topcoat, extreme UV and chemical resistance. Preferred for industrial assets, coastal environments, and long-service-life specifications.
Recommended Application System
Simplified two-layer system — direct to prepared steel
Dry Film Thickness: 130–180 µm total
Application method: Airless spray, roller, or brush
Surface preparation: Clean, degrease, remove loose rust — neutral pH (7–9)
Sustainability
By reducing steel roof surface temperatures and cutting air conditioning energy loads, EnduRE30C ValueShield supports reduced electricity consumption and carbon emissions across residential, commercial, and rural building types. Water-based and non-toxic, it supports NCC energy efficiency compliance and green building outcomes at a price point accessible to a wider range of projects.
Pure rare earth PDRC thermal performance, simplified and cost-effective — EnduRE30C ValueShield delivers passive daytime radiative cooling on Colorbond and steel roofing where heat reduction is what matters most.

EnduRE30C ValueShield for Steel Roofing
This page provides practical guidance for applying EnduRE30C ValueShield Radiative Cooling Coating for Steel Roofing, a cost-effective rare earth–based reflective cooling system designed for corrugated steel roofing sheets and steel roofing tiles, including steel and Colorbond®-type profiles. For detailed procedures and project-specific requirements, always refer to the official Construction Manual.
1) Application Methods
- Airless spray (recommended for uniform film build and coverage)
- Air spray
- Roller or brush (limited to small areas, edges, touch-ups and repairs)
2) Drying & Recoat Time
Drying and recoat times depend on temperature, humidity, airflow and substrate condition. Under standard conditions, typical guidance is as follows:
- Surface dry: approximately ≤ 1 hour
- Hard dry: approximately ≤ 24 hours
- Minimum recoat time: 4 hours
- Maximum recoat window: up to 24 hours
Reference conditions: ambient temperature 5–35°C, relative humidity ≤ 75% RH.
3) Application Conditions
- Steel roofing substrates must be sound, clean and dry, free from oil, grease, salt, dust and loose coatings.
- Remove rust, scale and oxidation by mechanical cleaning or abrasion prior to coating.
- Substrate moisture content: ≤ 10%
- Substrate pH: neutral range (pH 7–9)
- Application temperature: 5–35°C
- Relative humidity: ≤ 75% RH
- Ensure adequate ventilation in enclosed or confined spaces during application and curing.
4) System & Dilution Guidance
EnduRE30C ValueShield is a two-layer coating system consisting of a primer and a functional reflective layer. No protective topcoat is included in this system.
Dilution may be required depending on application method and environmental conditions. Where dilution is used, it should be carried out with deionised water.
Important: Exact dilution ratios and layer-specific guidance vary by component and application method. Always follow the Construction Manual and project specifications to achieve the intended performance.
5) Professional Use Notice
- EnduRE30C ValueShield is designed for professional application.
- Surface preparation quality is critical to adhesion and performance.
- This product provides reflective cooling performance only and does not include waterproof or hydrophobic protection.
- Actual coverage, drying time and thermal performance may vary depending on substrate condition, environment and application technique.
- Always conduct a small-area test and comply with site safety requirements, including appropriate PPE and ventilation.
EnduRE30C ValueShield is a practical solution for steel roofing applications where heat reduction is required and water repellency is not a critical requirement.
Radiative Cooling Principle for Coatings
Stay Cooler, Naturally with Rare Earth Technology
Easyto’s EnduRE30C™ Rare Earth Coatings use advanced radiative cooling to keep building surfaces dramatically cooler under the sun. Unlike traditional paints that only reflect visible light, our coatings combine thermal barrier, solar reflection, and natural radiative emission for all-round heat control. This results in lower indoor temperatures, reduced HVAC loads, and improved energy efficiency.
How Radiative Cooling Works
The coating structure consists of multiple functional layers: a protective surface, a rare earth radiative cooling layer, and a heat-insulating substrate. Together, these layers reflect, block, and re-radiate solar energy — ensuring surfaces stay cooler without compromising durability or aesthetics.
Three Key Mechanisms
1. Thermal Barrier
Heat conduction is reduced by using rare earth materials with low thermal conductivity, preventing excess heat from transferring indoors.
2. Thermal Reflection
The coating reflects solar radiation energy across a wide wavelength range (200–2500nm), reducing the amount of heat absorbed by the building surface.
3. Thermal Radiation
Any absorbed solar energy is re-emitted as harmless far-infrared radiation (8–13μm) back into the sky through the atmospheric window — a natural, maintenance-free cooling process.
Why Rare Earth Makes the Difference
Unlike conventional titanium-based paints, Easyto’s rare earth coatings maintain high stability, strong solar rejection, and long-term weather resistance. This ensures performance does not fade with time and continues to deliver measurable energy savings year after year.
Real-World Benefits
