Moisture is the enemy of any building’s longevity. Without proper protection, water infiltration can lead to mold growth and structural damage, costing thousands in repairs. Enter Mortairvent rainscreen, a cutting-edge solution designed to safeguard exterior walls. In this article, we’ll explore how Mortairvent, one of the best rainscreen products, prevents mold and structural damage, ensuring your building stays dry, durable, and healthy.
Why Moisture Management Matters in Exterior Walls
Exterior walls are constantly exposed to rain, humidity, and temperature changes. Without a proper moisture management system, water can seep into walls, leading to:
- Mold and Mildew: Damp conditions foster mold growth, posing health risks and degrading indoor air quality.
- Structural Damage: Water weakens wood, corrodes metal, and compromises insulation, reducing a building’s lifespan.
- Cladding Failure: Moisture trapped behind siding causes staining, peeling, or cracking of materials like stucco or brick.
A high-quality rainscreen product like Mortairvent creates a protective barrier, ensuring walls stay dry and resilient.
What Makes Mortairvent the Best Rainscreen Product?
Mortairvent, offered by Spycor Building Products, is a two-ply mortar deflection and ventilation system engineered for superior moisture management. Here’s why it stands out:
Advanced Ventilation Cavity: Mortairvent’s 95% open polymer-core mesh creates a pressure-equalized airspace behind cladding, allowing moisture to drain and air to circulate, drying walls quickly.
Mortar Deflection Fabric: The integrated filter fabric prevents mortar from clogging the drainage cavity, making it ideal for stucco, brick, and masonry veneer projects.
Durability and Sustainability: Made with 40% recycled content, Mortairvent is LEED-eligible, resistant to corrosion, and does not support mold growth.
These features make Mortairvent a top choice for architects, builders, and homeowners seeking the best rainscreen for stucco or other exterior cladding.
How Mortairvent Prevents Mold in Exterior Walls
Mold thrives in damp, stagnant environments. Mortairvent’s innovative design tackles this issue head-on:
- Rapid Drainage: The ventilation cavity channels water away from the weather-resistant barrier (WRB), preventing pooling that leads to mold.
- Continuous Airflow: By equalizing air pressure, Mortairvent promotes drying, eliminating the moisture mold needs to grow.
- Capillary Break: The open mesh design stops water from wicking into wall components, keeping interiors dry.
Unlike traditional furring strips, Mortairvent’s consistent airspace ensures no moisture traps form, offering unmatched mold prevention in exterior walls.
Protecting Against Structural Damage with Mortairvent
Water infiltration doesn’t just cause mold—it can destroy a building’s framework. Mortairvent’s rainscreen system prevents structural damage by:
- Shielding Sheathing: The drainage cavity keeps water away from sheathing boards, preventing rot and warping.
- Preserving Cladding: By venting moisture, Mortairvent reduces stress on exterior finishes, preventing cracks or blisters.
- Enhancing Longevity: Its durable polymer material resists degradation, ensuring long-term protection for your building.
With a Class A fire rating and integrated insect screen, Mortairvent offers comprehensive protection, making it a reliable choice for both residential and commercial projects.

When searching for rainscreen products, Mortairvent stands out for its ease of installation and cost-effectiveness. Unlike bulky alternatives, Mortairvent is lightweight, available in 6 mm (Mortairvent 202) and 10 mm (Mortairvent 203) thicknesses, and compatible with siding like wood, stone, and fiber cement. Its proven performance has earned rave reviews, with contractors noting fast delivery and seamless installation.
