This Hidden Roof Trick Cools Any Home By 30°F. Why Did NASA Hide It For 50 Years?
This Hidden Roof Trick Cools Any Home By 30°F. Why Did NASA Hide It For 50 Years? This video is about reflective cool roof coatings — a technology originally developed by NASA for spacecraft thermal protection. When applied to a regular roof, the coating reflects up to 90% of solar heat instead of absorbing it, dropping attic temperatures by 30-50°F and slashing AC bills. The video explains how dark roofs are silently cooking homes, how the coating works, why it's been kept out of mainstream construction for decades, and how homeowners can apply it themselves for a low cost.
