Standard Specification for Exterior Solar Radiation Control Coatings on Buildings
ABSTRACT
This specification provides the general physical and mechanical requirements for liquid-applied exterior solar radiation control coatings designed for exterior application on buildings or other structures for the purpose of reducing thermal loads on buildings by reflecting solar radiation from roofs and walls. The specification also includes the testing procedures by which the acceptability of the material may be determined. The physical and mechanical properties to which the coatings shall be tested and accordingly adhere to are total solid weight, solid volume, solar reflectance, infrared emittance, elongation, adhesion, water vapor permeance, flame retardancy, fungi resistance, water absorption, cured sample thickness, and outdoor durability.
SCOPE
1.1 The purpose of this specification is to provide general requirements for products used to reduce solar gains on buildings by reflecting solar radiation from roofs and walls. Radiation Control Coating (RCC) is a liquid applied material that cures to form a solid coating having a solar reflectance of at least 0.8 and an ambient temperature infrared emittance of at least 0.8.
1.2 This specification covers the physical and mechanical properties of liquid-applied RCCs designed for exterior application for buildings.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM C1483/C1483M-17(2022), Standard Specification for Exterior Solar Radiation Control Coatings on Buildings, establishes comprehensive requirements for liquid-applied coatings designed to reflect solar radiation from the exterior surfaces of buildings. The goal is to reduce thermal loads by controlling the amount of solar energy absorbed by roofs and walls. The standard details the physical and mechanical properties required for exterior solar radiation control coatings (RCCs), as well as the test procedures to assess their quality and effectiveness. Developed by ASTM International, this standard aligns with globally accepted principles for the creation of international standards, supporting the reduction of energy use and improving building performance.
Key Topics
Purpose and Scope
The specification covers the criteria and test methods for liquid-applied RCCs intended to reflect solar radiation, with a minimum solar reflectance and infrared emittance of 0.8.Material Properties
The coatings must be elastomeric or resinous materials, suitable for brushing, rolling, or spraying, with added pigments and additives to achieve required performance metrics.Performance Requirements
The standard specifies key properties and the corresponding test methods, including:- Total solids (by weight and volume)
- Solar reflectance and infrared emittance
- Elongation and UV durability
- Adhesion to substrates
- Water vapor permeance
- Flame retardancy
- Fungi resistance
- Water absorption
- Cured sample thickness
- Outdoor durability
Testing and Quality Assurance
Detailed methods are included for sampling, curing, and evaluating coatings to ensure they meet performance expectations under real-world conditions.
Applications
Exterior solar radiation control coatings have significant practical value in modern construction and building maintenance. The primary applications include:
Energy Efficiency
By increasing solar reflectance and thermal emittance, RCCs help reduce interior cooling loads, leading to lower energy consumption and utility costs in residential, commercial, and institutional buildings.Urban Heat Island Mitigation
Applying these coatings helps diminish heat absorption in urban environments, contributing to lower city-wide temperatures.Roof and Wall Protection
These coatings protect exterior surfaces from weathering, UV degradation, and fungal growth, extending roof and wall lifespans.Compliance and Sustainability Initiatives
Using RCCs that meet ASTM C1483/C1483M is often part of green building programs and supports sustainability certifications.Climate Adaptation
In hot climates, RCCs are an effective adaptation strategy to address rising temperatures and enhance building occupant comfort.
