Control Cavity works as a cavity weep detail in a furred-out, below-grade poured wall system because it has vertical channels throughout the wall system.
The vertical channels allow any moisture that may get into the wall to move down and out of the wall (both sides).
The sheets lay flat, provide 24 channels on both sides for every running foot of material and cannot be installed upside down or backwards.
The product may be fastened with concrete nails and is easily trimmed and field fabricated with utility knife.
