Masonry Cavity Wall Door Details

Exterior Masonry Door Details in Cavity Walls require attention to closing off the cavity and controlling any water that may have entered the wall above the door. 
The key features of the detail are the:

• a cavity vent that prevents mortar droppings from clogging the bottom of the cavity
• masonry flashing to direct any moisture to the exterior
• weep vent to let moisture out of the cavity and to equalize air pressure in the cavity with the outdoors (a similar vent is often placed at the top of the cavity)
• identifying the method for closing off the cavity above the door.
• reference to the structural lintel needed.
