Glass fiber gridding cloth is mainly woven with medium alkali or alkali free glass fiber yarn and coated with alkali resistant polymer lotion. Fiberglass mesh cloth has the characteristics of light weight, high strength, temperature resistance, alkali resistance, waterproofing, corrosion resistance, crack resistance, and dimensional stability. It can effectively avoid the overall surface tension shrinkage of the plaster layer and cracking caused by external forces. Lightweight mesh cloth is often used for wall renovation and wall insulation.

Grid fabrics can be divided into four categories according to their types: interior wall insulation fiberglass grid fabric, exterior wall insulation grid fabric, GRC product reinforced grid fabric, fiberglass tape, etc.

Dimensions of external wall insulation mesh fabric: 5x5mm, 4x4mm, weight: 80g, 130g, and 160g, width: 1000mm, 2000mm, length: one roll of 50m, 100m, or 200m, color: white (standard), blue, green, or other colors, packaging: according to customer requirements

The standard for fiberglass mesh cloth is the current national standard for external wall insulation technology (JG149-2003): the tensile strength of fiberglass mesh in the warp and weft directions shall not be less than 750N/50mm, and the retention rate of tensile strength in the alkali direction shall not be less than 50 per square meter of weight.

High quality alkali resistant mesh fabric has three main indicators, namely alkali resistance, tensile strength, and fracture strain, among which the most important is alkali resistance. The glass fiber mesh cloth used in the polystyrene board thin plastering external wall insulation system is required to have excellent alkali resistance because it is buried in cement mortar.

The surface of the high-quality mesh cloth is coated with a layer of polymer coating, which has a faint latex smell and is not pungent. The fake and low-grade mesh cloth is mostly made of urine glue, PVC lotion and vinyl acetate lotion, which has a pungent taste. Good mesh fabric has good toughness, stable chemical properties, and is resistant to alkali, acid, water, cement erosion, and other chemical corrosion. It is safe to use. The polystyrene board external wall insulation system can achieve a service life of 40-50 years. If alkali resistant glass fiber mesh cloth is used, it will pulverize and fracture in the alkaline environment of cement, greatly shortening the service life of the entire system. Therefore, alkali resistant glass fiber mesh cloth must be selected.
