Generated explanation

Three wall cross sections illustrate insulation voids and the convective air circulation that can occur within them. The left section shows shrunken insulation separated from the surrounding wall assembly, with arrows indicating air movement above and alongside the insulation. The middle section shows loose-fill insulation settlement leaving a void at the top of the cavity. The right section shows loose-fill insulation hung up on electrical wiring, leaving a void below the obstruction. Each assembly includes exterior siding and sheathing, wood wall framing, and interior drywall.
