Top 5 Features of 130g Wall-Covered Fiberglass Mesh Every Contractor Should Know

Read Time:4 Minute, 0 Second

In the construction industry, selecting the right reinforcement material can dramatically influence the longevity, performance, and stability of walls and coating systems. Among the many available options, the 130g wall-covered fiberglass mesh has risen to the forefront due to its superior engineering advantages and long-term reliability.

Made from high-quality glass fiber yarn and coated with alkali-resistant latex, this fiberglass mesh provides the strength and durability needed for cement, gypsum, roofing, stone, and wall reinforcement. As a result, contractors prefer it for both new construction and renovation projects.

This article highlights the top five features that make the 130g fiberglass mesh a must-have material in modern wall systems.

1. Superior Alkali Resistance for Long-Term Durability

Cement and plaster environments are naturally alkaline, and unprotected fibers can degrade quickly under such conditions. The 130g fiberglass mesh is coated with alkali-resistant latex, creating a strong barrier that shields the glass fibers from chemical attack.

This feature ensures that the mesh:

Maintains its tensile strength over time
Avoids structural weakening
Withstands long-term exposure to alkaline coatings

When embedded in plaster or cement layers, this alkali protection ensures that the reinforcement remains effective for the entire life of the wall.

2. High Tensile Strength to Prevent Wall Cracking

Walls often encounter tension caused by structural movement, temperature variations, and material shrinkage. Without reinforcement, these forces can lead to cracking and surface defects.

The woven yarn structure of the 130g fiberglass mesh delivers high tensile strength, enabling it to absorb stress and distribute load evenly across the surface. This significantly reduces:

Hairline cracks
Surface peeling
Render delamination

In both interior and exterior applications, high tensile strength ensures a stable, long-lasting wall system.

3. Lightweight and Easy to Install

A major benefit of fiberglass mesh over traditional reinforcement materials is its lightweight construction. The 130g/m² weight strikes a perfect balance—strong enough for wall reinforcement yet easy to handle on site.

Contractors can:

Cut the mesh quickly
Embed it seamlessly into plaster or mortar
Apply it on flat, curved, or irregular surfaces

Because it is easy to roll out and install, it contributes to improved construction efficiency and reduces overall labor time.

4. Compatible with Multiple Building Materials

The versatility of the 130g fiberglass mesh is one of its strongest advantages. It works effectively with a wide range of construction materials, including:

Cement
Gypsum
Lime-based plaster
Roof coatings
Wall insulation (e.g., EIFS)
Stone and brick substrates

This compatibility allows contractors to use the same reinforcement solution across different project types. It also ensures superior bonding, smooth finishes, and improved coating stability.

5. Customizable Mesh Sizes and Weight per Square Meter

Every construction project has unique structural, environmental, and design requirements. For this reason, Changshu Jiangnan Fiberglass Co., Ltd. offers custom production of fiberglass mesh:

Different mesh sizes (e.g., 4×4 mm, 5×5 mm)
Different weights per square meter
Different roll widths and lengths

This flexibility allows contractors to choose the ideal reinforcement grade for each wall system—whether it’s a lightweight interior finish or a rugged exterior coating exposed to weather.

Real-World Use Cases of 130g Fiberglass Mesh

Reinforcing Cement Plaster on Exterior Walls

The 130g mesh has been widely used to strengthen exterior renderings. In coastal construction projects where humidity and salt exposure pose challenges, its alkali-resistant coating offers reliable protection against cracking and material degradation.

Supporting Gypsum and Drywall Joint Systems

In commercial interior applications, contractors embed fiberglass mesh in gypsum layers to prevent joint cracks and surface delamination. Its flexibility ensures smooth, durable finishes.

Enhancing Roofing and Insulation Layers

The mesh is frequently applied in roofing coatings where thermal expansion and contraction occur regularly. Its dimensional stability helps maintain surface integrity.

Why Contractors Prefer Fiberglass Mesh Over Alternatives

Compared to traditional steel mesh or plastic mesh, fiberglass mesh offers several advantages:

Feature	Fiberglass Mesh	Traditional Steel Mesh
Weight	Lightweight	Heavy
Corrosion Resistance	Excellent	Prone to rust
Alkali Resistance	High	Low
Installation	Easy, quick	Complex
Flexibility	Strong	Rigid
Bonding with Plaster	Excellent	Moderate

For wall reinforcement, fiberglass mesh is clearly more practical and durable.
