Fibreglass Mesh is an essential component of our render systems. It helps provide strength and flexibility to our thin coat render systems ensuring that the render doesn&#;t crack in the years to come.

The fibreglass Mesh is made of neatly woven fibreglass thread. This type of mesh is widely used in plastering and rendering for wall reinforcement, external wall insulation and roof waterproofing. We offer different weights of mesh depending on the intended use. Typically, heavier mesh provides more impact resistance within the render system. At EWI Store the heaviest mesh we sell is our Orange Fibreglass Mesh at 165g/m2 . As a result of the weight, this is often used in areas that are likely to endure heavy impacts e.g. a wall where a football is kicked against it.
All of the mesh we sell is alkali-resistant, and this helps prevent it being broken down by the chemicals in the other mortars and adhesive materials. Fibreglass Mesh is also used to create reinforced stress patches around windows. Small squares are cut out and embedded in the basecoat to protect the edges of reveals. Corners in construction are inherently weaker, therefore Fibreglass Mesh can secure these areas. In combination with beading, these features can greatly enhance the strength of the system. Fiberglass mesh is also used in construction for its fire-resistant properties. When used in conjunction with fire-resistant materials, it can help prevent the spread of fire.
Where do you put the fibreglass mesh in render systems?
Within both render systems and external wall insulation systems, the fibreglass mesh is embedded within the basecoat layer. The mesh needs to be embedded within the basecoat while it is still wet. We always recommend getting the mesh embedded within the middle of the layer of the basecoat, rather than too close to the surface or sitting right next to the wall.
In thin coat render systems, the basecoat thickness is normally between 4-8mm, so installers tend to have different embedding techniques.
A notched trowel can be used to apply the basecoat to the wall at the required thickness. Following this, the mesh can be tapped into the basecoat. A straight edge trowel can then be used to &#;pull&#; the adhesive through the mesh by applying pressure to the basecoat.
Other installers will apply a thinner, first pass of adhesive, then tap the mesh in mesh in place and then apply a second layer of the basecoat. Either method is absolutely fine. However if you do go with the second method, ensure the first pass of basecoat has not dried before applying the second pass of mesh &#; the mesh needs to be embedded within fully wet product.
Overlapping mesh in basecoat
During weather and temperature changes, the external walls of your home expand and contract minutely due to the heating and cooling processes. Mesh is used to help the system &#;flex&#; with these building movements to help prevent cracking.

All of our mesh comes with markings 100mm from each end. This marking illustrates the overlap of the mesh required when installing it. Each strip of mesh needs to overlap the last by 100mm otherwise cracks can appear in this area over time.
The mesh provides additional strength to all thin coat render systems. The additional strength also helps prevent cracking so we would always recommend it.

Fiberglass mesh fabrics are mainly used as building materials in constructions and engineering projects. We use quality glass fiber materials for making of fiber mesh and fibre products. The glass fiber yarn / filament and its finished mesh products have good tensile strength.
As building material, Fiberglass mesh is mainly used for reinforcing render and plaster, ETICS ( (External Thermal Insulation Composite Systems), facade paster, render reinforcement. Most popular mesh, 160g/m2, mesh size 5x5mm, leno weaving.
Our major products include EIFS fiberglass mesh, fiberglass mesh for plaster reinforcement, fiberglass mesh for stucco, fiberglass window screening/insect screening, fiberglass tape, geogrid. We also supply fiberglass mesh machines to help our customers to set up fiberglass mesh production lines from glass fibre yarn drawing, yarn winding, warp arranging to fiberglass mesh production.
Fiberglass Mesh has excellent tensile strength, small elongation (3%), high elasticity and rigidity, large shock resistance, good chemical resistance, small water absorbent, the scale stability, heat resistance are good, low cost, not easy burn and forming glassy beads at high temperature. Black vinyl powder coated fiber glass meshes are specially treated fabrics with special benefits of durable uses and fire retardant property.
Alkali-resistant Fiberglass Mesh for Construction has excellent properties including water-resistance, alkali-resistance, flexibility, softness and resistance to aging. It is widely used in reinforcing walls, natural marble, plaster board, artificial stone materials and EIFS exterior insulation finishing system.
Adhesive or Non Adhesive Fiberglass Tape can be widely used in jointing plaster plates and mending drywall racks. The fiber mesh tapes enable faster joint, better adhesion without pasting or stapling.
Fiberglass mesh tape can be made with or without self-adhesive PET film backing. The durable water-proof alkali resistant mesh tapes are widely used in jointing plaster plates, drywall stucco netting, piecing together and making them join faster and adhering better. Also known as joint tape, drywall tape, plaster tapes.
Fiberglass Screen Mesh Netting is mainly used as fiberglass insect screen or sunshade fabrics for windows, doors, pool and patio. It can be made into window screen for window or door shield, pet screen, fiberglass reinforced geogrid fabrics, fiberglass solar screen and other forms for a wide range of applications. Plisse mesh and pleated fiberglass mesh panels are supplied for retractable window screen. Single layer fiberglass mesh woven with selvages is used for normal window screen. Fiberglass screen mesh can be made into alarm screens for security screening uses in addition to insect proofing.
Fiberglass Geogrid is a kind of alkali-free planar mesh material coated with high quality modified asphalt. It is warp knitted with oriental structure which gives full play of yarn strength and improves its mechanical property to make the product high tensile, tearing and creep-resistant. Moreover, the composite property of coating with asphalt makes full protection of the fiberglass matrix and greatly improves its wear resistance. Fiberglass geogrid has a good performance in pavement strengthening, track cracking and solving difficulties of strengthening the bituminous pavement.
Illustrations of Applications:
Our fiberglass mesh / screen / netting / fabrics are finding popular applications in cement construction, insulation system, geo engineering and various buildings.
Fiber mesh fabrics are used as ventilation, insect proof, geotextile, construction reinforcing and self-adhesive bonding materials. For reinforcing walls, insulation finishing system, marble tile, weld backing, plaster board, pipe wrapping, artificial stone materials bonding, etc.
Commonly used in the following fields:
&#; Wall Constructions and reinforcement
&#; Road Construction and Engineering Projects
&#; Ranch, Orchard, Farm Ventilation and Shading Screen
&#; Windows, doors and various different insect proof facilities and security alarm systems
