Alkali-Resistant Fiberglass Mesh: Premium Building Material for Insulation, Crack Prevention, and Structural Reinforcement

Discover the ultimate solution for modern construction with alkali-resistant fiberglass mesh—a high-performance composite material engineered to enhance durability, insulation, and surface integrity in both interior and exterior applications. This advanced building fabric is widely used across residential, commercial, and industrial projects worldwide, offering superior resistance to corrosion, impact, mold, insects, and fire. Whether you're reinforcing plasterboard joints, insulating walls, or strengthening roofing systems, this versatile product delivers consistent performance under diverse environmental conditions.

Key Features:

• Exceptional alkali resistance ensures long-term stability in cementitious environments
• High tensile strength and dimensional stability prevent cracking and delamination
• Fire-retardant properties meet international safety standards
• Moisture-resistant and mildew-proof design enhances longevity
• Customizable specifications including mesh size, weight (55–180g/m²), width (10–150cm), and length (30–100m per roll)

Our fiberglass mesh comes in standard configurations such as 4x4mm and 5x5mm mesh sizes with weights of 120g, 145g, and 160g/m²—ideal for drywall repair, plaster reinforcement, and thermal insulation. The material can also be tailored to specific project requirements, including custom hardness levels, colors, and packaging options like woven bags, plastic wrapping, carton boxes, or palletized units for bulk shipping. A 20-foot container holds approximately 1,100 rolls (4x4mm, 160g/m², 50m each), while a 40-foot container accommodates up to 2,600 rolls—making it an efficient choice for large-scale contractors and importers.

Common Applications:

• Wall crack repair and joint finishing in plasterboard installations
• Insulation layer integration for energy-efficient buildings
• Roof waterproofing membranes using bitumen or polymer-based adhesives
• Reinforcement of concrete, mortar, and stucco surfaces
• Base fabric for grinding wheels, mosaic backing, and marble cladding
• Enhancement of plastic composites and fiber-reinforced materials

Installation Process:

1. Ensure the wall surface is clean, dry, and free of dust or grease
2. Apply the fiberglass mesh tape over cracks or seams, pressing firmly to eliminate air bubbles
3. Use a trowel to spread joint compound or plaster evenly over the mesh, embedding it fully
4. Allow drying time before lightly sanding for smoothness
5. Apply additional coats of finish coat or paint to achieve a seamless, professional appearance
6. Remove any excess tape edges and seal joints with a compatible filler or composite material

Frequently Asked Questions:

What makes alkali-resistant fiberglass mesh different from regular glass cloth?

The special coating applied during manufacturing provides protection against alkaline chemicals found in cement and lime-based mortars, preventing degradation over time. Regular glass fabrics may deteriorate quickly when exposed to these substances.

Can I use this mesh for external wall insulation?

Absolutely. Its weatherproof and moisture-resistant properties make it ideal for external thermal insulation systems (ETICS) where durability and thermal efficiency are critical.

Is it suitable for DIY home improvement projects?

Yes. With proper preparation and application techniques, homeowners can effectively use this material for repairing drywall, sealing window frames, or reinforcing weak spots in plastered walls.

How do I store the rolls before installation?

Keep them in a cool, dry place away from direct sunlight and moisture. Store vertically if possible to avoid warping or creasing.

What are the typical mesh sizes available?

We offer 3x3mm, 4x4mm, 5x5mm, and 10x10mm mesh sizes—each suited for different types of reinforcement needs, from fine detailing to heavy-duty structural support.
