Brief Description:Premium alkali-resistant fiberglass prevents wall cracking, peeling & delamination.High tensile strength, weather & ageing resistant. Multiple sizes. New & renovation.

Haochen Fibreglass Mesh, full name Alkali-resistant Fibreglass Mesh, is an indispensable core anti-crack reinforcement auxiliary material for wall finishing and external & internal wall insulation construction. It is split into two main product categories: external wall insulation mesh and internal wall decorative anti-crack mesh, tailor-made for outdoor building insulation projects and indoor domestic anti-crack works respectively. Woven from premium fibreglass rovings, the mesh blank is impregnated with polymer alkali-resistant emulsion and thermally cured and set. It features high tensile strength, ample flexibility, alkali and corrosion resistance, and excellent resistance to fraying and breakage. With consistent performance and superior on-site workability, it serves as a fundamental functional material for wall anti-crack treatment and render reinforcement in modern construction.

External wall insulation mesh delivers outstanding weather resistance and long-term protection with an enhanced thickened coating formulation. It boasts excellent UV resistance, weathering resistance and freeze-thaw resistance, able to withstand prolonged outdoor sunlight, rain exposure and seasonal temperature fluctuations without premature ageing or functional failure. It is mainly used for external wall insulation rendering, roof screeding, external wall refurbishment of aged residential estates and repair works of external insulation layers. Once embedded within anti-crack render, it evenly dissipates drying shrinkage stress and thermal deformation stress, relieving structural tension caused by temperature differences on external walls. It fundamentally eliminates frequent defects including cracking, hollowing, peeling, delamination and water seepage of external insulation layers, stabilises the structure of external wall insulation systems and greatly improves the stability and service life of external wall insulation projects.

Internal wall decorative anti-crack mesh is lightweight, soft and highly conformable, specially engineered for indoor wall finishing scenarios. It is widely adopted in full-wall rendering, plaster and putty screeding, joint treatment between old and new wall sections, ceiling panel joints and substrate preparation before wall tiling and other domestic finishing procedures. Fine cracks readily occur on internal walls due to settlement and moisture shrinkage. This mesh effectively locks the render surface layer and restrains crack propagation, thoroughly resolving common domestic finishing troubles such as cracked emulsion paint, flaking plaster and joint cracking, delivering smooth and intact internal wall finishes with longer-lasting decorative performance.

Whether for external wall insulation and roof protection of new-build structures, old building renovation, indoor wall refurbishment or whole-house render levelling, fibreglass mesh can effectively boost the overall toughness and structural strength of render coats, improve wall integrity and inhibit crack spread. The external grade features anti-ageing and high weathering performance for harsh outdoor working conditions; the internal grade is supple, easy to handle and suitable for detailed domestic finishing works. Available in a comprehensive range of specifications, the product has wide compatibility, simple laying operation and stable finished results. It is a high-quality universal wall anti-crack reinforcement material for both civil engineering and domestic decoration.

Summary The external wall mesh focuses on outdoor thermal insulation and long-term anti-crack performance with superior weather durability, while the internal wall mesh targets indoor decoration crack prevention and fine screeding. This dual-grade product fully satisfies construction demands for both external and internal walls. It effectively reinforces wall render layers, reduces the probability of wall cracking at source and substantially extends the service life of building substrates and decorative finishes.
