Source: What Is Masonry Flashing?
Proper placement of flashing is crucial when it comes to masonry cavity walls. It should be positioned below the initial layer of masonry above the ground level to ensure effective protection. Additionally, flashing should be installed at various points of support such as structural floors, shelf angles, and lintels in cases where masonry veneers are designed as per Section R703.
Where Should Flashing Be Put in Masonry Cavity Walls?
When it comes to masonry cavity walls, the placement of flashing is crucial for ensuring long-term durability and preventing water infiltration. According to industry standards, flashing should be positioned beneath the first course of masonry above the finished ground level. This helps create a barrier between the foundation wall or slab and the masonry veneer, redirecting any water that may accumulate on the walls surface.
In order to comply with Section R703 of the building code, masonry veneers must be designed with flashing located at these key points. This not only fulfills regulatory requirements but also enhances the overall integrity of the wall system. The correct placement of flashing in these areas is vital for preventing water from seeping into the cavity and causing structural damage or compromising the insulation.
This proactive approach to moisture management helps safeguard the structures longevity and minimizes the potential for costly repairs in the future.
It’s essential to understand the significance of flashing when it comes to protecting buildings from water damage.
