The EIFS system provides a durable, weather-resistant primary barrier.
EIFS with Drainage uses a secondary air/weather barrier to provide a cost-effective, added level of protection to the sheathing and cavity against moisture and air intrusion.
This space between the foam and the substrate, creates a drainage cavity.
This type of exterior insulation finishing system is intended to help water that may get behind the EIFS to follow a safe path back to the outside.
