ProGuard™: The Next Generation of Glass Mat Sheathing from Mada Gypsum

At Mada Gypsum, we’ve built our reputation on delivering innovative, high quality building solutions that meet—and exceed—modern construction demands. ProGuard™, our advanced glass mat sheathing board, continues this tradition by offering unparalleled performance, versatility, and ease of installation. Below, we take a closer look at why ProGuard stands out as an essential choice for today’s architects, contractors, and builders.

The Advantages of Glass Mat Technology

• Enhanced Mold & Moisture Resistance

Glass mat–based boards are known for their superior resistance to mold growth, dampness, and humidity. With <5% water absorption (compared to significantly higher rates in traditional boards), ProGuard helps maintain the structural integrity of walls and exteriors—especially in climates where moisture can compromise a building’s lifespan.

• Lightweight & Easy Handling

One of the biggest challenges in construction is managing heavy boards that slow down projects. ProGuard boasts a notably lighter density (about 848 kg/m³) than common fiber cement boards, making it easier for crews to cut, carry, and install. This translates directly into faster build times and reduced labor costs.

• Robust Fire Performance

ProGuard meets ASTM C1177 standards and delivers reliable fire protection. With potential fire endurance of up to 120 minutes (ASTM E119) in the right system configurations, it provides peace of mind for designers and building occupants alike.

• Structural Flexibility & Crack Resistance

Traditional boards can be prone to cracking or shrinkage when subjected to temperature swings or shifting substrates. By contrast, ProGuard’s glass mat core allows for a certain degree of flex without compromising its structural strength, providing long term dimensional stability and helping keep surfaces smooth.

Why ProGuard? A Quality Comparison

When stacked up against other board options—such as generic fiber cement boards or our own ProCem boards—ProGuard excels in several key categories:

• Weight: At 10.6 ± 0.2 kg/m² (for 12.5 mm thickness), ProGuard is significantly lighter, improving on site efficiency.
• Water Absorption: Under 5%, ensuring minimal swelling or warping over time.
• Mold Resistance: Rated at 10, demonstrating excellent performance in both humid and wet conditions.
• Ease of Cutting & Installation: Can be cut and snapped quickly, eliminating the need for specialized equipment.
• Warranty & Standards: Compliant with ASTM C1177, plus Mada Gypsum provides a 10 year system warranty on ProGuard based assemblies.

ProGuard’s Unique Selling Points

• Superior Mold & Moisture Resistance

Protects projects from microbial growth and structural damage—ideal for high humidity regions or external sheathing applications.

• Weather Resistance with Extended Exposure

Engineered to endure challenging climates and reduce the risk of degradation over time, providing extended coverage during construction phases.

• Thermal Performance & Fire Resistance

Effective thermal conductivity (0.25 W/mK) and robust fire ratings ensure a safer, energy efficient structure for occupants.

• Smooth Surface & Aesthetic Appeal

Creates a perfect substrate for a variety of finishes, giving architects and designers the freedom to achieve any desired aesthetic without compromise.

• Sustainability & Environmental Friendliness

With a lightweight design and extended lifespan, ProGuard helps reduce waste, shipping emissions, and resource consumption—aligning perfectly with greener building initiatives.
