What is conter flashing
Counter flashing is a technique used in construction to prevent water from penetrating into a building at joints or openings where a vertical surface meets a horizontal surface. The top edge of counter flashing is typically installed to divert water away from these vulnerable areas.
When it comes to where the top edge of the counter flashing is inserted or covered, one common practice is to insert it into masonry joints. Masonry joints refer to the gaps or spaces between bricks, stones, or other masonry materials used in the construction of a building.
By inserting the top edge of the counter flashing into these joints and sealing them with mortar or other appropriate sealants, it helps to create a waterproof barrier that prevents water from seeping into the building.
