1. The worst exterior wall thermal insulation mesh is very cheap, and it will break when folded twice. The production process is clay crucible drawing, and the glass fiber mesh is usually made of some waste glass such as beer bottles. It belongs to the production process prohibited by the state, and the outer coating is not an alkali-resistant emulsion. From an intuitive point of view: the workmanship is relatively rough, generally sold more in Lunjuan in the market, often lacking in length, easy to shift, and easy to puncture the skin. This type of fiberglass mesh is used where the insulation quality is insufficient. The weak joint layer generally loses its strength after two months. If the mortar is knocked out and the glass fiber mesh cloth is taken out, the glass fiber mesh cloth will become powdery with light grinding.
2. There is another kind called imitation platinum exterior wall insulation grid cloth. But sometimes it is difficult to judge the authenticity, but its quality cannot meet the requirements of the external wall insulation with a real alkali-resistant glass fiber mesh cloth on the outside. The fiber diameter is relatively thin, and the glass is made of broken glass, also called mixed silk yarn. This is an imitation of often some clear flat fiberglass.
3. Standardized mesh cloth with good quality has good alkali resistance in the selection of materials. The advantage is that it has all the alkali resistance and high tensile strength in warp and weft, and the fence net is made of platinum. The woven latex is based on glass fiber. It makes the product have good hand feeling and good construction compliance and greatly reduces the amount of plastering mortar.
4. Exterior wall thermal insulation grid cloth Mesh cloth external thermal insulation system scope:
● External wall insulation grid cloth is usually used: 3 3 45 grams, 5 5 80 grams
● The insulation system of materials used in the external wall insulation grid cloth adopts: 5 5 130 grams, 5 5 145 grams
● External wall insulation grid cloth: 5 5 160 grams
● External wall insulation grid cloth or insulation layer less than two meters: 3 7 10 300 grams
