Where houses were once made primarily from wood, plaster, stone, and natural materials, today they are filled with plastics and synthetic building products. In this video, I break down how modern building materials changed, why plastics became dominant in construction, and how these materials affect indoor air quality and daily chemical exposure inside homes. Many homeowners experience headaches, brain fog, poor sleep, or persistent chemical smells without realizing their house itself may be contributing. We’ll look at common plastic-based materials used in modern construction, how off-gassing works, and why airtight homes can trap pollutants indoors. This video is for homeowners, builders, and anyone interested in healthier building practices and understanding what’s actually in the materials around them.
