Invention on Instagram: "Foam insulation begins as a liquid that is sprayed into wall cavities where it quickly expands to fill every gap and seam. This expansion allows it to reach areas that traditional insulation cannot touch creating a continuous thermal barrier that reduces air leaks and improves energy efficiency. Because it conforms to the shape of the space it helps create a tighter and more consistent building envelope. As the foam expands it often grows slightly past the face of the st
