The distinctive look and durability of brick, stone, and stucco
cladding systems have made them extremely popular in recent
years. However, they're not waterproof. Moisture will find its
way into these wall systems by way of hairline cracks in the
mortar joints, broken sealant joints, splashing from horizontal
surfaces, such as the ground, and projecting horizontal surfaces,
such as windowsills. Once this moisture penetrates the outer
wall surface, it will become trapped in the wall system with
nowhere to escape, creating the perfect environment for toxic
mold growth. That's why Advanced Building Products has created
Mortairvent
®
, a two-ply mortar deflection and ventilation system
specifically designed for use with manufactured stone, stucco,
EIFS, and brick applications.
Why Mortairvent
®
?
Our innovative rainscreen technology equalizes the air-pressure
within the wall system by creating a ventilation cavity between
the weather resistant barrier (WRB) and the exterior wall.
The polymer-core mesh creates the airspace while the filter fabric
blocks mortar from seeping into the newly formed cavity while
still allowing the moisture to drain, not remain, in the wall system.
The constant draining and convective fashion ventilation
greatly reduces the threat of toxic mold for generations to come.
These moisture issues are more common in areas with frequent
freeze-thaw cycles that allow wind-driven rain to penetrate the
mortar and collect in the wall. They are also found in areas with
low rainfall and high humidity.
Results From Moisture Infiltration
1. Exterior surfaces such as stucco and EIFS will crack and
peel unless damaged substrates are repaired. Moisture
trapped behind manufactured stone could dislodge the
stone due to various freeze thaw cycles.
2. Structural damage will take affect, which will cause an
unsafe environment to work and live in.
3. Mold, mildew and rotting will begin to take place.
Wet wood and gypsum products
create a food source for mold to
thrive in. This will eventually lead
to Sick Building Syndrome.
