How Infrared-Blocking Roofing Works to Reduce Heat Gain #309644 (License: Personal Use)

The image depicts a simplified cross-section of a building under sunlight, where wavy lines labeled “visible” enter through the roof, while another set labeled “infrared blocked” are stopped at the surface. The illustration emphasizes passive solar design principles-using material properties to selectively filter solar spectrum components for thermal regulation. It serves as an educational tool for architects, builders, and homeowners exploring energy-efficient construction.

Used on sustainability, green building, or HVAC education pages; supports content about cool roofs, low-emissivity coatings, and passive cooling strategies. Matches user intent to understand how building materials interact with solar radiation.
