- Blocks moisture-- hinders mold development and wood rot.
- Limitations noise transmission-- contributes to a quieter living environment.
- Safeguards structural parts-- keeps framing and drywall from water‑related degeneration.
When the seal deteriorates, each of these advantages erodes, causing discomfort and possibly pricey repairs.
