Heat Reflective Roof and Wall Coating
Incorporating cool roofing and wall coatings is an essential design element when aiming for energy efficiency in building construction or renovation. Astec Energy Star’s heat reflective coating systems are designed to reflect infrared heat, significantly reducing the amount of absorbed heat in a building.
Key Benefits
Infrared Heat Reflection: Astec Energy Star coatings reflect up to 50% of solar heat through infrared reflection, even in dark colors. This reduces the heat absorbed by the building envelope, leading to cooler indoor temperatures and energy savings.
Environmental Impact: A reduction of just 1°C in temperature can lead to a 10% saving in power consumption, contributing to overall energy efficiency [Macquarie University].
Durability: Lowering the solar absorptance of a roof by 0.25 per square meter can equate to removing 64 kg of CO2 emissions from the atmosphere over the roof’s lifespan [Department of Climate Change].
Application Areas
Industrial Metal Roofing
Astec's system seals and waterproofs seams, flashings, and fasteners using polyester mat embedded between liquid waterproofing materials. This creates a monolithic seal that resists UV degradation and wind-driven rain, ensuring watertight integrity.
Asbestos Roofing
The Astec Asbestos System stabilizes and rehabilitates weathered asbestos roofs without high-pressure cleaning. It uses mould retardants, sealers, and elastomeric topcoats to lock into the asbestos matrix, providing a safe and cool surface.
Flat Deck Waterproofing
A seamless membrane is applied during construction or retrofitting to prevent water transmission and moisture accumulation. It remains flexible at low temperatures and resists UV degradation, extending its lifespan.
Concrete Tiles
The Astec System replaces weathered finishes with heat reflective elastomers, forming a waterproof seal that resists UV degradation and wind-driven rain.
Advanced Coating Technologies
Textures and Renders: Astec Energy Star textures reduce absorbed heat by reflecting infrared light, even in deep tone colors. This minimizes thermal shock and may eliminate the need for additional insulation.
Elastomeric Wall Finishes: These coatings provide crack-free protection against water and carbon dioxide ingress while maintaining flexibility over time. They bridge substrate cracks effectively, ensuring long-term durability.
Compliance and Certification
Astec Energy Star coatings are independently tested for absorbance and emittance values, ensuring compliance with the Building Code of Australia (BCA). These coatings are integrated into energy efficiency compliance software like Accurate and Energy Plus. Their low absorptivity results in reduced construction costs, enhanced energy ratings, and positive environmental impacts.
