Why is fiberglass mesh needed?

якісну скловолоконну сітку high-quality fiberglass mesh

Starting repairs in our home, taking care of its insulation, we want to complete construction work “for centuries”. So that the walls are strong, the plaster does not crumble, and cracks and crevices do not form. It turns out that success in this matter does not require large expenditures: your repair will remain beautiful, smooth and not cracked for at least 25 years, if choose a high-quality fiberglass mesh!

Everyone who is professionally engaged in construction knows: fiberglass mesh is an integral element for strengthening the surface during plastering. If plaster is applied without the use of a fiberglass mesh, then soon it will begin to crack and fall off. The plaster itself is not able to cope with atmospheric pressure, sudden changes in temperature, humidity and, moreover, reinforce the walls. Fiberglass mesh takes on the load, giving a fortress to the finish layer.

But it is not enough to use any fiberglass mesh.

A good result is determined only by the excellent quality characteristics of the fiberglass mesh.

Many importers, in order to remain competitive in this segment, seek by any means to reduce the selling price, and go along the path of purchasing the lowest quality mesh. The one that dilapidates right in the hands when working with it. Very often, cheap fiberglass mesh manifests instability in an aggressive environment – it simply dissolves in the plaster. On average, the price of a LATYMER professional facade fiberglass mesh is no more than 5-7% of the cost of the insulation system itself. However, it is precisely its quality characteristics that guarantee the durability of the entire energy-saving design.

What are the main parameters of the LATYMER fiberglass mesh?

Meets the world mass per unit area standards.

LATYMER fiberglass mesh meets international EAD quality standards and is marked with the CЄ marking. It is available in the range from 125 g/m2 to 165 g/m2. It is the indicators of this mass per unit area with a mesh size of 5×6/5×5/4×5 mm that are most often used to perform facade works. This requirement is spelled out in the technical documentation ETAG 004. You should not save and buy goods of lower mass per unit area, as you will certainly reduce the reliability and strength of your facade.

Resistant to stretching

The quality weaving and impregnation of fiberglass mesh LATYMER is easily checked using the following test: a small piece of material must be crumpled like a “snowball” and released – the mesh will completely restore its original shape. In addition, the features of weaving are visually easy to see if weaving is folded in half and controlling the size and alternation of cells.

Tensile strength of mesh for plaster

This indicator in the normal (as-delivered) state should be at least 30 N/mm on the warp yarn direction and within 40 N/mm on the weft yarn direction. Weft yarns are almost always stronger than the warp yarns; therefore, when testing mesh, some importers indicate in the Product Quality Certificate only one indicator of tensile strength, which does not reflect the real picture. The tensile strength of the fiberglass mesh LATYMER Professional is over 32 N/mm on the warp yarn direction and more than 44 N/mm on the weft yarn direction. This data complies with European quality standards!

Alkali-resistance of mesh for plaster LATYMER

The most important indicator of fiberglass mesh is alkali resistance. Alkali resistance of mesh is its ability to maintain its tensile strength properties in an alkaline environment. The fact is that plaster mixtures and mortars based on cement have an aggressive alkaline environment with a pH factor > 11. In such an environment, the tensile strength of mesh decreases, while for cheap, mainly Chinese, it drops In conclusion, we would like to give advice: strengthen the facades only with high-quality fiberglass mesh.
