Panel module
Align architectural rhythm with fabrication efficiency.
Envelope Performance
High-Performance Rainscreen Cladding
Ventilated façade systems separating the exterior weather layer from the primary wall to improve durability, drainage and architectural freedom.
Performance Intent
Designed as a system, not selected as a sheet material.
HDA approaches rainscreen cladding through system geometry, support conditions, interfaces, environmental loads and installation sequence. The material is one component within a larger building-envelope response.

Technical Considerations
What must be resolved
Subframe design
Coordinate brackets, rails, tolerances and loads.
Open joints
Control visual joints while managing water ingress.
Cavity performance
Provide drainage, ventilation and fire compartmentation.
Edge conditions
Resolve corners, openings, parapets and base details.
Maintenance
Plan access, replacement logic and long-term appearance.
