Perforated Control Cavity™
Single Wythe Moisture Control
PCC 4816, PCC 4832, PCC 2416, PCC 2432
Perforated Control Cavity Highlights
Perforated Control Cavity maintains a separation between the interior surface of a single-wythe CMU structural wall and the moisture sensitive materials of the interior finished wall. It creates a drainage system that allows moisture to travel down and out of the wall into a drainage field.
Features/Benefits
- Perforations allow cross ventilation for better drying
- Rigid and durable; will not compress behind interior finished wall
- Prevents water bridging
- 96% post-consumer recycled content
- “The Green Guard® Classic Wrap provides a layer of air resistance to increase energy efficiency, and it acts as a water-resistive barrier that breathes, allowing moisture vapor to escape and reducing the potential for condensation buildup.” (see Green Guard Classic Wrap website for specs)
Perforated Control Cavity Installation
- Install with channel pattern running up and down vertically and fabric to interior
- Overlap all edges and ends a minimum of 1”
- Overlap horizontal edges shingle fashion to outside concrete, masonry substrate (see Lap & Fastening Detail) – upper sheet laps behind (back-laps) lower sheet
- Cover entire wall surface, top to bottom, in this fashion
- Mechanically fasten with concrete nails or power fastener; fastening pattern 2’ on center (see Lap & Fastening Detail)
