Key priorities: Code compliance, performance, and scheduling.
IECC/ASHRAE Compliance: Factory-integrated R-value (R-2.5 to R-10 CI) simplifies meeting 2024 IECC energy-code targets.
Faster Dry-In: Allows earlier window and WRB integration, enabling interior trades to start sooner.
Simplified Envelope Design: Combines a secondary WRB, insulation, and a backer for standard claddings into one system—reducing materials and subcontractor scope.
Less Trades to Coordinate: By providing a backing for standard claddings as well as insulation and a secondary WRB, Builders have less trades to manage onsite.
