1. INTRODUCTION
The purpose of this Technical Manual is to indicate the most suitable method
to optimise the Emmedue building system during installation.
These pages will enable the erection of buildings having standard features
using panels and other elements that are normally employed in the Emmedue
building system.
Pag. 2
2. DESCRIPTION OF THE EMMEDUE BUILDING SYSTEM
2.1. FUNDAMENTALS OF THE EMMEDUE SYSTEM
The basis of the Emmedue construction system is based on a series of
foam polystyrene panels and steel wire meshes, whose shape has been
especially designed to apply structural plaster during panel installation.
The aim is that of providing a system of industrialized modular panels
that, besides requiring shorter erection time compared to the conventional systems, permit to copy with structural and load-bearing functions,
offering in the same time a fast assembling and laying, high thermal and
sound coefficients and a wide range of shapes and finishes that may be
achieved during the building process.
2.2. COMPOSITION OF THE EMMEDUE PANELS
The basic element is made as follows:
A) A foam polystyrene core that is atoxic, self-extinguishing and
chemically inert with varying density and thickness depending on panel
type.
B) Electrowelded steel wire meshes made of galvanised drawn steel
wires placed on both sides of the polystyrene sheet and connected by
means of joints of the same material. The wire gauge of the net varies
according to panel type and mesh direction.
2.3. PLASTERING
After the panel assembly, structural plaster should be sprayed and/or
poured on the panel - depending on panel type.
Pag. 3
2.4. ADVANTAGES OF THE EMMEDUE SYSTEM
• High heat and sound insulation
• Easy to move, rapid assembly and high durability
• High structural capacity and resistance
to earthquakes and
hurricanes
• No skilled labour is required
• Lower costs and erection time

ne systems, etc.
• Panels of customised length and thickness
• Solid panel connection
• Panel surface and Emmedue plastering machines are especially desi-
gned for a smooth plaster spraying
• Emmedue panels’ meshes also include connection flanges
• The polystyrene core can avoid the thermal bridges
• Emmedue panel does not change following exposure to weather
conditions
• Ecological in all its parts.

3. CLASSIFICATION OF THE EMMEDUE PRODUCTS
The various types of Emmedue panels, their fields of application, standard
sizes and complementary Emmedue products are described below.
The thickness of the polystyrene sheets as well as the length of the panels
may be customised, according to the different project requirements of the
customers.
Generally speaking, the thickness of panels is usually determined according
to its different conditions of heat insulation and required structural
behaviour. In the latter case, infact, a greater moment of inertia may be
achieved by increasing the interval between the two concreted or plastered
surfaces.
As far as the degree of heat insulation of polystyrene is concerned, a
finished panel of a 10-cm thickness with a 4-cm thick polystyrene core
(density 15 kg/m3) corresponds to an ordinary brick wall 64-cm thick.

compressive strength.
This panel is generally used for buildings of no more than 4 storeys, also in seismic
areas, for floor slabs and covering slabs whose spans are 4 m. at maximum. However,
in such cases, the panel should be further reinforced with additional meshwork and a
greater amount of concrete layer on the upper side - from 4 to 6 cm - in keeping with
the calculations made.

This type of panel enables the use of the Emmedue system for floors and roofs by
inserting reinforced ribs in the special spaces and subsequent concrete casting on site.
Infact the reinforcement of the panel is integrated during the panel assembly by the
insertion of additional reinforcement bars – to be substantiated by calculations –
inside the panel ribs.
It is an ideal solution for floor slabs having spans up to 6.5 m. and overloading up to
400 daN/m2. Furthermore, where the assembly sequence needs to be maximised, as
far as the erection schedule is concerned, it is possible to use iron stiffening ribs in
the pods of the panel.

This panel consists of an expanded polystyrene block shaped according to designing requirements and reinforced by a dual steel mesh joined by several steel wire
connections welded in electro-fusion across the polystyrene core.
Suitable reinforced and finished with casting on site in the suitable spaces, it is
used, for the construction of flight of stairs up to a maximum span of 6 m. having
an accidental overload of 400 Kg/m². The additional reinforcement to be placed
inside the holes is formed by a lattice of ribbed bars.

3.7. EMMEDUE PLASTER SPRAYERS FOR WALLS & CEILINGS
The use of these devices easily enables a time saving by 50% and with no need for
skilled labour. Thanks to Emmedue plaster sprayers, the plaster may be applied with
a degree of adherence that could not be achieved manually.
In one hour, one worker using a plaster sprayer with a continuous flow of material
placed nearby can apply a plaster layer of about 1 cm. over an area of up to 60 sq.m.
Emmedue plaster sprayers are available in two versions: W for walls and C for
ceilings. Both models feature four holes for different types of plaster and come with
all the necessary tools to clean the machine after use.
User’s instructions
1. The air pressure should be kept constant within a 70-120 pound (500-800 kPa)range.
2. No special plastering-machines are needed and the panel to be plastered requires
no previous preparation.
3. For the plaster to be applied to the wall, the container should be placed at a
distance of 10-20 cm.
4. For the plaster to be applied to the ceiling, the upper edge of the container should
almost touch the panel at a maximum distance of 2-3 cm.
Plaster Sprayers Maintenance
1. During the usual interval between the application of two layers of plaster, we
recommend to place the empty container in a bucket filled with water and make it
work two or three times.
2. Remove lateral bolts and wash the inside of the machine at least once a week.
Compressors:
Either electrical or internal-combustion engine compressors may be used keeping in
mind the following data:
Engine power (HP)
From 3 to 4
From 5 to 6
From 8 to 10

Note 2: When only one
plastering-machine is used, the
ideal cubic capacity of the
compressor container is 220
litres (not lower than 130 litres,
but with pressure regulator).

4.1. EMMEDUE HOUSE
This chapter deals with the utilisation of Emmedue single panels PSME in
the building walls and floors.
4.1.1. Foundations
The work made with Emmedue Panels starts from the foundations. This
might be a concrete bed, a raft foundations constituted by moderate
dimension beams or a connection beam supported on piles. Such foundations
should be sized up according to classical criteria keeping in mind the geomechanical characteristics of the ground.
The recommended foundations provides for anchoring bars (corrugated iron)
whose dimensions, quantity and length will depend on the degree of stress at
the base of the panel (just like an indication, it could consist of bars ∅ 6 mm
placed at 40 cm intervals 50 cm. above the level of the beam).
Pag. 18
4.1.2. Assembly of PSM Single Panels for Walls
At the beginning of assembly operations Emmedue panels are anchored to
the foundations bars by pliers and steel wires. In order to guarantee the continuity among the elements, the Emmedue panels are equipped, on both sides,
with an overlapping mesh wing that enables to join each panel to the mesh of
the closer panel.
During this stage, to achieve proper heat
insulation, no empty spaces should be left
between the joints of polystyrene cores. In
addition, special attention should be paid
to the panels being placed in a perfectly
vertical position and well aligned so to avoid any possible structural weakness of
the structure.
During assembling the main
openings for doors and balconies
have to be considered as foreseen in
the design. Minor openings might
be obtained after assembling panels
by using cutting instruments, such
as circular saws, shears and even
knives and pliers.
Pag. 19
4.1.3. Bracing meshwork installation
All the building internal and external edges, either vertical or horizontal, are
reinforced with angular mesh (RG1), which gives the structural mesh greater
continuity.

Horizontal section
The openings’ vertex are all braced, on both sides, thanks to the positioning
of a flat meshwork (RG2) at 45° as to the edge to be reinforced.
The window and door lintels, according to their lenght and the window sills
whose span is longer than 1.20 m. can be integrated with additional reinforcements on both sides.
Pag. 20
For the assembling of the frames, the polystyrene should be reduced in the
areas of the fastening points in order to enable the correct insertion of the
metallic clamps inside the panel meshes.
Pag. 21
4.1.4. Installation of Single Panels for Coverings
Basically, the same instructions as for the installation of vertical panels
apply. The panels should be first joined together and then anchored to the
wall by means of steel wire and/or meshes.These panels work as floor frames
so that the panel wave runs along the shorter span of the area to be covered.
The wall edges and angles, both interior and exterior, will be strengthened by
RG1 bracing meshworks or any other reinforcements to be calculated each
time.

4.1.5. Installation of Emmedue staircase PSSCE
This panel is ordinary used for the construction of flight of stairs till around 6
m. long having an accidental overload of 400 Kg/m².
Once the stairs panel is assembled and the lattice is placed inside the panel
internal channels, the latter are completed with gravel concrete (whose
particle size is < 12 mm) and its minimum strength is Rck > 250 daN/cm2
The concrete may be cast in the panel ribs contemporaneously with casting of
the upper coating.
Successively, the plaster layer (2.5 cm. thick) is applied both on the lower face and on the sides of the flight while on its upper side the flooring (marble,
ceramic tiles, etc.) can be directly laid on. an adhesive layer. This panel enables the erection of stairs of classic dimensions only. Nevertheless, it stands out
for its easy installation and its especially light structural weight.
Pag. 23
4.1.6. Laying of plumbing, electric installation and other systems
The laying of the pipes for the plumbing and electric installation as well as
heat system etc. has to be carried out after the complete assembling of the
walls and before they are sprayed with concrete. The polystyrene is melted
with a source of heat (hot-air gun or generator, etc.).
Pipes, ducts and wires (electricity, water, gas,
etc.) are easy and rapid to place under the
metal mesh by simply making a chase in the
polystyrene by means of a hot-air generator
Pag. 24
The flexible pipes are easily placed under the meshwork, whereas rigid ones
are placed after cutting the mesh. Then the meshwork area needs to be
restored by means of an additional reinforcing mesh connected to the panel
meshwork.
Note: Copper pipes could be insulated from the panels steel meshwork with felt,
PVC of similar materials.
Pag. 25
4.1.7. Details of balconies and bow-windows
The balconies can be executed by Emmedue floor panel PSSGE with
additional anchoring bars being anchored to the floor. The quantity and the
diameter of these bars depend on the length of the overhangs besides the
overload to be substantiated during the project design. Later an upper slab of
4-5 cm will be casted and a 3cm-plaster layer on the lower side will be
sprayed on.
Pag. 26
4.2. Walls structural plaster
4.2.1. Features
Emmedue panels are completed during their installation by applying cementsand structural plaster on both sides for an average thickness of 3 cm. The
panel thus obtained will form a reinforced concrete slab with an expandedpolystyrene core. The resistance of these panels will be 250 daN/sq.cm, at
least and the particles of the sand used for the concrete will measure between
0 and 5 mm.
4.2.2. Concrete mix design
The cement-sand plaster used is dosed with a volumetric ratio of 1:4.
Starting from the resistance curves obtained in relation to both the amounts
of cement and plaster settling, it may be derived that Emmedue system
concrete may be mixed with approx. 350 Kg of cement for each cubic meter
of mixture.
For each cubic meter, the dosage specified in weight for each of the
materials in the mixture will be as follows:
Cement
Sand
Water
:
:
:
350 Kg (7 bags)
1.570 Kg
180 litres
The quantity of water should vary according to the humidity of the aggregates. In any case the consistence, measured by the Abram’s cone, should be
S2 (slump 5 cm).
4.2.3. Plastering of the walls
Plaster should be applied by means of special plaster sprayers.
It is essential that plaster is malleable and applied vigorously so as to remove
the air between the underlying materials - polystyrene and plaster - and fresh
plaster and thus obtain a compact and uniform surface.
The maximum thickness of each layer should be approx. 1,5 cm while the
layer of smooth plaster with fine sand, if required, should not exceed 5 mm.
Plastering excessively large areas is a practice to be avoided.
Pag. 27
Following the panels’ alignment and their vertical assemblying, the required
bracing meshworks should be inserted while the meshworks previously cut
to install the various systems should be restored - to confer greater continuity
to the structure—and the additional reinforcement should be placed.
At this stage, structural plastering operations may be started.
On both sides of vertical panels a layer of
structural plaster (Rck = 250 daN/cm²)
should be sprayed for an average thickness
of approx. 1.5 cm.
The interval between the spraying of the first and second layer should be as
short as possible so to avoid any possibile problem of adherence between the
layers.
During this phase, it is
possible to plaster the part of
the ceiling where it joins with
the walls; this area should not
be wider than 20 cm.
On the second day, the
screeds and posts used to
align and erect panels may be
removed, leaving only those
at the weakest points, such as
a panel between two
openings and the like.
Pag. 28
4.2.4. Finishing of the floors.
A)Before casting the floor. Place posts and boards at 1.1-m. intervals, slightly
increasing the height of posts at the centre of the floor slab. Panels hog should
measure approximately 0.50 cm for every metre of span.
B) In case the Emmedue single panels are emploied, before casting the
slab, the first plaster application to
the ceiling slab has to be carried out.
C) Concrete casting of the ceiling
slab. If the PSSE floors are emploied, the workers should take care
to walk exclusively on the wooden
bridge boards laying on the posts.
D) The designer should verify the floor
panel reinforcement and, if needed,
should integrate it with additional reinforcement rods - to be substantiated by
calculations—inside the panel ribs (see
detail below).
E) We recommend the
use of concrete Rck=
250 daN/cm² whose
maximum particlesize measures 12 cm
for a thickness from 4
to 6 cm.
Pag. 29
F) Once the ceiling slab concrete has reached the right cure degree, the posts
should be removed starting from the centre outwards so as to gradually
transfer the load to the floor slab. Subsequently, the unplastered areas left by
the supporting boards may be completed. Both the ceiling and the overhangs
are plastered in the same way as the walls.
4.2.5. Plaster cure
A regular plaster cure process is crucial to obtain the necessary structural
resistance of the elements. In order to avoid an excessive evaporation from
the plaster layer, after the surface is completed, keep constantly wet the walls
and the ceilings for at least 3 days from the application of the plaster layer or
the casting execution.
This procedure allows the completion of the natural hydration process of the
cement by guaranteeing the cure of the plaster and reducing cracking due to
shrinkage.
In case chemical curing membranes are used, any possible adherence
problems with either the other layers or finishing materials should be
identified for the following laying of the plaster finishing.
4.2.6. Finishes
Coverings should be laid on the plaster as late as possible. The longer the
intervals between plaster cure and the laying of the coverings, the more will
be plaster shrinkage. There will also be greater certainty that the covering
will remain well adherent, and the remaining plaster micro-cracks will be
more stable and will be covered with satisfactory aesthetic results.
Considering the above, the surface is waterproofed, the ceiling slab is
covered, the finishing works are carried out, window and door frames are
installed, walls are painted and covered, etc.
4.2.7. Other indications
• The plaster applied by the plaster sprayer is more compact and uniform
and its shrinkage level is lower. Moreover, its structural capacity is
improved and shows a higher waterproofing quality and durability.
Pag. 30
Precautions
Do not overload partition walls on one side only. Instead, plaster both
sides alternatively.
If a panel is cut during erection and its meshwork has no wire-crossing
joints, panels may be joined with flat meshwork (min. width 22.5 cm);
Additional plasticizer agents generally reduce the risk of cracks;
Highly-flexible coverings or paints prevent the creation of cracks in the
plaster;
4.2.9. Fixing objects to partition walls
A. Lightweight objects:
25 mm. screws, pins or similar devices may be used.
B. Heavy objects:
(Shelves, water-tanks, WC, etc.). We recommend the use of plastic pins
with 45-mm screws or similar devices.
C. Very heavy objects:
During erection, metal pins may be inserted in plaster pallets.
Differently, a threaded pin fastened with epoxy resin may be used.

4.3. WALLS ERECTED BY EMMEDUE DOUBLE PANELS
PDME
In buildings with more than four storeys, lower levels walls should be erected with
Emmedue double panels and any possible additional steel reinforcement.
After panels have been fastened, aligned and vertically installed, structural
concrete made with cement, sand and gravel is cast inside them.
In this way, not only the panels act as a real formwork, but they also offer solid
reinforcement and optimal heat and sound insulation.
Pag. 33
Once concrete is cast inside double panels and all the systems are installed in
the same way as for single panels, both sides of panels are plastered. In this
case, only one coat of plaster is needed - enough to cover the mesh, before
applying the selected finish.

First of all, trace the outlines of the partitions on the ground as well as along
the pillars and contact walls, if any. Take particular care with the horizontal

metal profiles which should be as long as
holes for
each panel’s thickness, and fixed to the

with a sealing epoxy resin at a distance of
40 cm. from each other. Subsequently the iron members will be fixed to the
meshes on both sides of the panel . In case of partitions or loads not covered
by normal standards, the above indications should be verified.
In case of a panel disjunction, an elastic
