GLASS MESH FABRICS FOR REINFORCEMENT – APPLICATION GUIDE
Stronger ideas for a sustainable world
Saint-Gobain Adfors
SGA specializes in the manufacture and sale
of reinforcement fabrics, scrims and glass mat for
construction, engineered composites and industrial
products.
SGA combines both a weaving and a textile
transformation company, each with over 50 years
of experience, and each occupying the position of
leader and expert in their respective markets which are
advantageously complementary and global.
The following applications of SGA product can be
found in the construction sector:
– reinforcement open meshes for façade cladding and
other applications,
– multifunctional glass fibre wall coverings,
– bituminous membranes reinforcement, etc.,
– insect screening meshes,
– tapes for dry wall joints reinforcement.
SGA construction branch is constantly strengthening
its position among the worlds leading producers of
glass fiber technical fabrics. As a glass fiber mesh
producer it is considered to be the worldwide leader.
Mesh fabrics combined with specially designed
surface treatments opens the possibility of their use
in a wide range of applications. The treatment based
on styrene-butadiene assures both alkali resistance
and increased mechanical durability at the same
time, features especially required by the construction
industry. Additionally, other fabrics based on PVAc or
styrene-acrylate are also used for different applications.
Nowadays the majority of mesh fabrics for ETICS and
render reinforcement are manufactured by SG Adfors,
European branch of SGA. The quality of its products
has been assured by a quality control system according
to the latest standard ISO 9001:2000.

List of applications by types of mesh fabrics
Mesh fabrics are wound on paper tubes with inner
diameters of 45, 76 or 152 mm. The quantity of
fabric wound on the tube is determined by customer
requirements and varies from just 50 meters to the
thousands of meters needed for machine processing.
Mesh fabrics are offered in widths of between 10 cm
and 285 cm in addition to the standard 100 cm.

SGA group pays the same attention to the protection of the environment – our plants are equipped with state-of the
art technology and therefore we are fulfilling the toughest environmental requirements – Saint-Gobain Adfors have
obtained ISO 14000 certificate.
External thermal insulating composite systems (ETICS)
The Increasing price of energy in conjunction with
deteriorating environmental conditions are forcing us
to take serious measures, particular regard to energy
saving. ETICS are especially designed to fit exactly this
purpose, therefore they become a part of our every
day lives. They offer long lifetime with high durability to
aggressive weather conditions.
Variations of external temperature, mortar shrinkage
and movements of the insulating panels may cause
clefts or hair cracks on the surface of the system.
Therefore as an important part of certified ETICS
a glass fiber mesh is used, which thank to the special
alkali resistant surface treatment and excellent
mechanical properties insures required durability of all
ETICS.
Thanks to the high standard of quality of our mesh
fabrics, they become an integral part of many certified
ETIC systems offered on the market by major system
suppliers today. Particular certificates obtained by
Saint-Gobain Adfors are listed in the table on page

Application Procedure1. Attach plinth lath by means of Parker’s bolts.
Depth of lath profile should correspond with
thickness of insulating board.
2. Apply mortar as shown on picture.
3. Install boards tightly side by side so no glue is
allowed to pass between them.
4. Boards should be installed continuously.
5. If necessary, secure boards also by disk
dowels.
6. Example of dowels lay out.
7. All corners and edges should be reinforced
by special heavy mesh or special corner lath.
Reinforcement should be fully covered by
reinforcing coat.
8. Apply basic layer of reinforcing coat. When
coat is still soft, imprint the reinforcement mesh
gently into it. The mesh belts are imprinted from
the center outwards.
Individual belts should overlap each other as
minimum 10 cm on each side.
9. Immediately after placing the mesh apply the
upper layer of reinforcing coat.
10. The surface should be painted when dry.
11. Apply façade render.

External and internal render reinforcement
To reinforce exposed areas of external and internal
plaster (wall joints, windows and door corners and
the channels for water or gas pipes and electrical
wiring), an alkali resistant glass fibre mesh is highly
recommended by the majority of producers and
suppliers of construction technology (YTONG, ISO
SPAN etc). The recommended mass per area (1 m2) is
usually about 145 g with a mesh size of approximately
8 × 8 mm. However, other producers may use different
types of mesh like R117 and R131 with a mesh size of
around 4 × 4 mm.
Another circumstance in which mesh fabrics should
be used is when two materials with different coefficients
of expansion meet one other. In this case there is a risk
that the plaster coat will crack. In order to absorb the
tension, it is recommended that a strip of glass fibre
mesh is applied over the joint.
The mesh must be embedded in the material
avoiding creases and blisters.
Mesh type R267, R275 or R451 are specially
designed to reinforce areas exposed to increased
stress like a corner or a plinth.
Remarks:
a) Two mesh belts should overlap by 10 cm (minimum)
on each side.
b) The mesh should be placed at least 2 to 3 mm under
plaster surface.

Reinforced lightweight construction boards
Construction boards (made of polystyrene or
polyurethane) reinforced on both sides by glass fibre
mesh are successfully used in the building industry.
The boards are about 60 cm wide, up to 2.5 m long and
up to 80 mm thick and are useful wherever the straight
or difficult shapes of wall’s partition are required. They
can be used on different kinds of houses partitions,
walls of bathtubs and shower baths, swimming pools
walls, pipes covers and so on.
Besides application flexibility, they combine
lightness, easy handling and processing, shape
stability, thermal insulation and impermeability with
moisture vapors. Because of the reinforcing glass fibre
mesh attached to the boards with special adhesive, the
board’s surface forms an ideal substrate for thin-bed
tile laying or for the application of render finishes.
When used in combination with specially designed
installation hardware, builders have a very creative
building material at their disposal.
The possible uses are demonstrated in the pictures
herewith.
Mesh fabrics designed for the construction board
reinforcement should also comply with machine
processing requirements

Marble slab reinforcement
Another area in which glass fibre mesh fabric is used
is the large scale marble processing industry. When
a large marble slab is made or lower quality marble is
used, the glass fibre mesh is bonded on one side of the
slab. This process prevents marble slab damage during
manipulation and further processing.
In most cases, polyester resin is used to bond mesh
fabrics to the slab. To assure strong adhesion, mesh
fabrics with special surface treatment (marked A105)
are used. This treatment dissolves when exposed to
polyester resin ensuring good glass fibre soaking by
resin and therefore a strong and reliable connection.

Electrical floor heating mats
Electrical floor heating mats offer new, warm comfort
whenever the fancy but on touch cold floor tile are used.
This system offers floor heating without the complex
installation of heating bodies, exchangers and other
difficult-to-install systems. The advanced electronics
heating management and the relatively cheap heating
mat installation requires almost no maintenance
expense, making this an effective electrical heating
system.
Electrical heating mats take up very little space and
can therefore be installed directly over old flooring. New
installations require as little as 15 mm space including
new tiles and adhesive.
Electrical wiring is attached to glass fibre mesh belts
wide from 30 to 100 cm by self adhesive tape or by
hand eventually machine sewing.
The use of glass fibre belts with self-adhesive
coating on one side makes the installation of electrical
heating mats even easier.

Installation procedure1. Electrical floor heating mat. The floor must be sufficiently cleaned before the heating mat is laid-down.
2. The heating mat is unfolded on the floor. The heating mat should be laid down without any creases and then
secured so as to prevent it slipping. When laid down direction is changed, cut the glass fibre mesh belt. Be
very careful not to cut heating wire.
