Why EIFS Drainage Planes Matter

Modern EIFS performance depends on water-management details behind the finished surface, not just the acrylic texture homeowners see.

The old EIFS problem

Poorly detailed EIFS can trap moisture. Modern systems address this with drainage, sealant strategy, flashing, and correct transitions.

Details that matter

Window and door interfaces, penetrations, roof-wall transitions, and grade clearances all affect long-term performance.

  • Drainage plane
  • Moisture barrier
  • Flashing integration
  • Sealant joints

Why contractor choice matters

A good EIFS job is a wall system, not just a finish coat. Proper prep and detailing are central to performance.
