PROSOCO’s Thru-Wall Flashing is an extra-tough, abrasion-resistant flashing designed for easy installation and long-term durability. Thru-Wall Flashing is perfect to use for:
- Transition membranes from below-grade waterproofing to above-grade air barriers.
- Parapet applications, especially when connecting to roofing membranes.
✅ Step 1: Apply your air barrier
The process of installing Thru-Wall Flashing is done after the primary air barrier has been installed to the field of the wall. The flashing is designed to adhere directly to the air barrier.
✅ Step 2: Peel half of the film backing off the Thru-Wall Flashing
Peel off the film from the vertical portion of the flashing.
✅ Step 3: Place the Thru-Wall Flashing on the vertical surface
Use hand pressure to tack it into place. Follow up with a J-roller to secure the bond.
✅ Step 4: Peel other half of film backing
✅ Step 5: Place the Thru-Wall Flashing onto horizontal surface
Use hand pressure to tack it into place. Follow up with a J-roller to secure the bond.
✅ Step 6: Counterflash with FastFlash
To complete the installation, apply FastFlash as your counterflashing. This is the go-to detail to ensure a watertight and reliable seal.
