This processing guideline describes the individual steps for the manufacture of ECONTROL® insulating
glass with ECONTROL® laminated glass panes.
This processing guideline is based on the process of a normal insulating glass production for the manu-
facture of solar control insulating glass units and heat protection insulating glass units. It describes, in
particular, the process steps deviating from the standard process, which must be considered for the
manufacture of ECONTROL® insulating glass units.

2 Delivery, storage, preparation of ECONTROL® laminated glass
2.1 Terms and definitions
EControl-Glas provides the insulating glass manufacturer with a laminated glass, which is referred to as
either EC9 or EC11 - depending on the total thickness. Each ECONTROL® laminated glass consists of
2 glass panes, which are interconnected with a conductive film (1 mm thick):
EC9 4 mm glass / 1 mm film / 4 mm glass
EC11 6 mm glass / 1 mm film / 4 mm glass
The ECONTROL® laminated glass has a step of 4 mm at one of the two narrow edges. At this step, the
two contact tabs (so-called Polyflex contacts) protrude.
The positions 1 and 4 are uncoated float glass surfaces.
The ECONTROL®
laminated glass has 2 circumferential
seals. Together, the two seals have a width of 8 mm on
the step edge and a width of 12 mm on the other edges
The external visible seal is a sealant made of Polyisobu-
tylene, PIB, (in the insulating glass industry simply re-
ferred to as “butyl”). The second internal sealing com-
pound is transparent.
As a rule, EControl-Glas delivers the sealed ECON-
TROL®
laminated glass with an edge cover to the insulat-
ing glass manufacturer. This edge cover consists of a
dark green PET adhesive tape. The adhesive tape pre-
vents the carryover of butyl sealing compound to the
machines of the insulating glass manufacturer.

Attention!
The ECONTROL®
laminated glass units must always be put down, stored or transported in such a way
that the step edge is never the standing edge. Otherwise, there is the risk of damaging the contact tabs.
Depending on the requirements or preferences of the customer, the ECONTROL® laminated glass can
be refined with another glass pane and PVB film to form an ECONTROL®
laminated safety glass.
2.2 Delivery, storage
ECONTROL®
laminated glass units are delivered to the customer in the following condition: on glass
racks, wrapped in black film1, heat-sealed, packed on wooden frames or crated.
Attention!
ECONTROL®
laminated glass units on glass racks must not be stored outdoors. Direct sunlight to the
ECONTROL®
laminated glass units (with or without partial shading) must be avoided by all means.
Attention!
ECONTROL®
laminated glass units on racks without lightproof film may only be transported in closed
trucks.
Basically, EControl-Glas delivers the ECONTROL®
laminated glass units in bright (decoloured) state to
the insulating glass manufacturer.
In addition, EControl-Glas provides the insulating glass manufacturer with all cable harnesses required
for the manufacture of the ECONTROL® insulating glass units. A testing device for determining the cor-
rect polarity (ISOPOL testing device) and associated insulating glass test reports are also provided by
EControl-Glas.
The scope of supply of EControl-Glas includes:
ECONTROL®
laminated glass (one or more)
Cable harness

2.4 Test report
EControl-Glas requires the insulating glass manufacturer to test the ECONTROL® insulating glass. The
test must be performed after laying and soldering the cable harness, but before carrying out the sealing
process. For the test, EControl-Glas provides the insulating glass manufacturer with the testing device
ISOPOL on loan.
The testing device ISOPOL answers the following questions:
Is the polarity of the cable harness correct?
Does the temperature sensor provide a plausible value?
Is the total resistance of the ECONTROL®
laminated glass within the plausible range?
If the polarity is correct and the measured values are plausible, a green indicator light is illuminated on
the ISOPOL testing device and a 6-digit checksum is shown on the display. This checksum must be
entered manually in the form Test report.
If the polarity is reversed, or the measured values for the temperature sensor or the measured values of
the total resistance are not within the plausible range, the indicator light on the ISOPOL testing device is
illuminated in red.
Further information are provided by EControl-Glas in the operating manual of the ISOPOL testing device.
Figure 3 shows an example of a test report that contains the following information:
Order number, customer, commission
Item number, dimensions, pane number
Measured values Ip, Im and R (are shown on the display of the ISOPOL testing device)
Checksum (is also shown on the display of the ISOPOL testing device)
Comments, date
Name and signature of the tester

2.5 Marking the ECONTROL® laminated glass units
ECONTROL®
laminated glass units are marked with an EC pane label on the side directed towards the
outside in the insulating glass (position 1) between the contact tabs. The EC pane label contains the
information on order number, item number and pane number as well as the dimensions [in mm].
Figure 4: Sample of an EC pane label with company logo, dimensions, customer name (here:
sample), pane number (here 20000_1_1) and Data Matrix Code. The first five digits correspond to
the order number (20000). Then, the item number (_1) and the serial pane number (_1) are shown.
2.6 Marking the ECONTROL® insulating glass units
The insulating glass manufacturer is responsible for the information given on the pane label of the fin-
ished ECONTROL®
insulating glass. The pane label contains: Commission, customer name, order num-
ber, item number, pane number and information on the pane size.
Attention: (see also figures in Section 13.3; Packaging and shipment)
The label and the note “Inside” must be affixed to the inner pane (counter pane) of the insulating glass
in order to avoid shadowing effects on the ECONTROL®
laminated glass.
It is not allowed to affix labels to the outside (position 1) of the ECONTROL®
insulating glass.
2.7 Preliminary cleaning of the ECONTROL® laminated glass
Before starting the production of the ECONTROL®
insulating glass, strongly adhering contaminants (e.g.
edge sealing material) on the ECONTROL®
laminated glass must be removed using suitable aids.
Edge sealing residues on the ECONTROL®
laminated glass and along the edges must be carefully re-
moved using a razor blade (or other suitable aids).
Attention: There is the risk of damaging the glass surfaces by scratching!
During the manufacturing process concerning ECONTROL®
insulating glass, the EC pane label (see
Figure 4) must remain on the ECONTROL®
laminated glass. The EC pane label and its lettering are
waterproof and suitable for standard glass washers.

3 Provision of the counter pane (with low-e coating)
3.1 Quality and selection of the counter pane
Regarding its quality (glass thickness, toughened safety glass, heat-strengthened glass, laminated
safety glass, emissivity), the counter pane can, basically, be freely selected according to the technical
regulations of the insulating glass production. The insulating glass manufacturer is responsible for the
quality of the counter pane. In general, the insulating glass manufacturer can freely select the manufac-
turer of the counter pane (PILKINGTON, GUARDIAN, TRÖSCH, AGC-INTERPANE, SAINT-GOBAIN
and others). However, if the end customer wants a defined counter pane, EControl-Glas passes this
request on to the insulating glass manufacturer (obligatory).
For the selection of the counter pane, the requirements of the customer, the structural engineers and the
relevant building regulations must be observed.
The standard structure of the insulating glass laminate provides for the use of 4 mm float glass with a
low-emission coating (low-e coating) with an emissivity εn ≤ 0.04, a black spacer for a gap between inner
and outer pane of 16 mm and a gas filling with argon.
The insulating glass manufacturer is solely responsible for ensuring the required Ug values pursuant to
DIN EN 673.
If deviating structures are produced (gap between inner and outer pane, gas filling, glass thickness,
glass type, εn), the technical values (Ug values and g values in particular) must be checked according to
the standards DIN EN 673 and EN 410 and corrected, if necessary.
Comment: For the useful operation of an ECONTROL® insulating glass pane, the counter pane must
definitely be provided with a low-e coating. Without this low-e coating, the variation of the g value is low.
As a result, the sun protection function is insufficiently fulfilled in dark state. An ECONTROL® insulating
glass without low-e coating does not meet the specification of EControl-Glas.

3.2 Edge stripping
The insulating glass manufacturer is responsible for performing the edge stripping of the low-e glass
units used. The edge stripping of the low-e coatings is necessary to avoid corrosion of the silver-based
coatings that is caused by air (oxygen and/or moisture). If no edge stripping is performed, the low-e
coating may corrode (starting at the edges). As a result, the adhesion to the insulating glass adhesive
and the butyl seal is reduced. This may lead to the destruction of the insulating glass laminate.
Figure 5: Schematic representation of insulating glass constructions with different depths of the
edge stripping of the low-e counter pane: on the left with 10 mm edge stripping, on the right with
13 mm edge stripping; the edge stripping of a depth of 10 mm corresponds to the minimum re-
quirement by EControl-Glas
The edge stripping of the low-e glass must be at least 10 mm all round. For the production of insulating
glass with EControl laminated glass, EControl-Glas recommends to make an edge stripping at such a
depth that the dividing line between low-e coating and decoated zone is approximately centrally below
the primary seal (butyl, polyisobutylene) - see Figure 5. At a depth of the spacer of 6 mm, an edge
stripping of 13 mm is optimal.

4 Spacer production
4.1 Spacer materials
Materials made of metal (stainless steel and aluminium), plastic and metal/plastic combinations can be
used as spacers.
The use of thermoplastic spacers (TPS) is forbidden and not approved by EControl-Glas.
The standard structure provides for a spacer made of stainless steel in a width of 16 mm. Deviations
relating to the dimensions of the spacer are possible. However, such deviations have to be checked by
the insulating glass manufacturer regarding the practicability of the connection technology (see Section
9) und the influence on the Ug value. EControl-Glas recommends the use of black spacers.
4.2 Positioning the spacer
The spacer must be positioned in such a way that it overlaps the transparent edge sealing at the step
edge by approx. 2 mm in the edge area of the ECONTROL® laminated glass (see Figure 6: red circles).
For this, the all-round distance from the inner edge
of the spacer to the glass edges must be 16 mm. On
the non-step edges, the overlap of the spacer to the
transparent edge sealing is 4 mm.
Attention:
The insulating glass manufacturer is responsible for
the correct dimensioning of the spacer.

nated glass [EC9] and insulating glass with in-

5 Washing the counter pane and the ECONTROL® laminated glass
The counter pane is edge-stripped and washed according to the instructions of the manufacturer or the
supplier.
The ECONTROL® laminated glass is placed - with the step edge - in such a way on the inlet section of
the washer that the step of the ECONTROL® laminated glass is directed towards the inside to the gap
between inner and outer pane in the insulating glass, and that the Polyflex connections are arranged
against the running direction of the washer (see Figure 7). Otherwise, there is the risk of damaging the
connections during the washing process.
The ECONTROL® laminated glass can be washed just as ordinary laminated glass.
Figure 7: Direction for the entry of the ECONTROL® laminated glass into the washer.
IMPORTANT:
During the washing process, attention must be paid to the correct position of the step edge and the Poly-
flex connections: see sketch in Figure 8.
The EC pane label with the EC serial number remains on the laminated glass during the washing proc-
ess.
After the ECONTROL® laminated glass has passed through the washer, the ECONTROL
® laminated
glass must be dried. Subsequently, the step edge must be free of water drops. If this is not the case,
adhering drops must be removed manually using an absorbent cloth.

6 Butyling of the spacer
The butyling of the spacer is performed according to the plant configuration and is the responsibility of
the insulating glass manufacturer.
With regard to the ECONTROL® laminated glass, the following particularities must be considered when
butyling the spacer.
The butyling must be applied all round and without interruption(s) to both sides of the spacer. It has
to be complied with the system description of the licensor.
The butyling is performed with the thermoplastic resin polyisobutylene (PIB). In everyday speech, this
plastic is referred to as butyl. EControl-Glas recommends polyisobutylene by FENZI or Kömmerling.
The plastic polyisobutylene (PIB = butyl) is also referred to as insulating glass sealant and fulfils the func-
tion of sealing the gap between inner and outer pane to the environment (if performed correctly) since
the permeability of water vapour, noble gases or air is very low. The terminological counterpart to the
insulating glass sealant is the insulating glass adhesive. The insulating glass adhesive may be made of
polysulphide, polyurethane or polysilicones and has - compared to the insulating glass sealant PIB - a
significantly reduced sealing function, but a significantly increased adhesive function.
When using insulating glass adhesives based on silicones for a UV-resistant edge compound (e.g. Dow
Corning 3362 or Kömmerling GD 920), special attention must be paid to the quality of the spacer butyling
since silicone adhesives have a high gas permeability for noble gases such as argon and krypton.
7 Fixation of the spacer on the ECONTROL® laminated glass
When fixing the spacer, it must be ensured that it is positioned on the smaller pane of the ECON-
TROL® laminated glass in such a way that the transparent sealing tape at the inner edges is completely
covered (see Figure 8, red circles).
For information on the dimensions of the spacer, see chapter 4.
Attention:
After positioning the spacer and pressing it into position, the transparent sealing tape of the ECON-
TROL® laminated glass must no longer be visible. Due to the fact that the area of the transparent seal-
ing tape is not dimmable, a bright streak would otherwise be visible on the finished insulating glass from
the outside when the ECONTROL® insulating glass is coloured.

Attention:
Attention must be paid to an accurately fitting positioning.
Attention:
The spacer must always be positioned on the smaller glass pane of the ECONTROL® laminated glass.
Figure 8: Fixation of the ECONTROL® laminated glass: The
distance from the inner edge of the spacer to the edges of
the larger glass pane is always 16 mm. The overlap of the

8 Joining and pressing the ECONTROL® laminated pane to the counter pane
The joining and pressing of the ECONTROL® laminated glass and the counter pane is performed ac-
cording to the specification of the insulating glass manufacturer.
Attention:
It must be ensured that the ECONTROL® laminated glass and the counter pane are always placed in
such a way that - after the bonding - the step edge of the ECONTROL® laminated glass is directed to-
wards the gap between inner and outer pane, i.e. towards the inside. The EC pane label (see Figure 4)
with the EC pane number is located on the outside on position 1.
Attention:
Further labels may only be affixed to the inside of the ECONTROL® insulating glass! Labels on the out-
side of the ECONTROL® insulating glass result - when exposed to the sun – can lead to colour differ-
ences in later operation.
9 Connection technology (cable harness)
9.1 Appearance and shape of the cable harness
EControl-Glas uses 2 different types of cable harnesses (see Figure 9):
GV 07 “Small” plug with “thin” cable
SVG 04 “Large” plug with “thick” cable
For each insulating glass to be produced, EControl-Glas defines the type of the cable harness depend-
ing on the glass dimensioning and the length of the pane cable (cable from the insulating glass to the
control unit).
The cable harness with the “small” plug is symmetrical. Thus, there is no reverse polarity protection. In
order to distinguish the front from the back, however, one side is marked with a white dot (see Figure 9
left).
The “thick” plug is not symmetrical. It has 2 different sides. Thus, there is a reverse polarity protection
regarding the “thick” plug.
In general, i.e. for most applications, EControl-Glas uses the cable type SVG 04. However, in some spe-
cific cases, the cable type GV 07 must be used.

symmetrical regarding front and back; one side is marked with a white dot for distinction (left);
the front and back of the “thick” plug are different; thus, there is a reverse polarity protection
regarding the “thick” plug
The cable harnesses of both types consist of a 4-wire cable with white cable sheath and a 4-pin plug
(see Figure 10), which is preassembled by EControl-Glas and delivered to the insulating glass manufac-
turer both suitably for the respective ECONTROL® laminated glass pane and in coiled form.

The cable harness with its 4-wire cable is
partially stripped. The part that is not stripped
has a length of 20 cm. With regard to the
finished insulating glass, 15 cm of the 20 cm
are outside the insulating glass adhesive and
5 cm are inside the insulating glass adhesive.
The border is marked with a black line (see
Figure 11).

9.3 Positioning the temperature sensor
The position of the temperature sensor is fixed and must be strictly observed. In the standard case, the
white pane cable with the cable plug is located centrally at the step edge. The temperature sensor is
positioned centrally with the grey cable at the standing edge (see Figure 16). Here, the temperature sen-
sor is to be positioned in such a way that it has to be in direct contact with the ECONTROL® laminated
pane (for details and sketches, see Section 10.4)
The position, where the temperature sensor is to be positioned, is marked with a sticker on all ECON-
TROL®
laminated panes. This sticker comprises black letters (T-Sensor) on a red background (see Fig-
ure 15). The sticker can be found on position 1 of the ECONTROL® laminated glass.

With regard to models, EControl-Glas specifies the position of the temperature sensor and informs the
insulating glass manufacturer about this position in the form of a model drawing (see e.g. Figure 17).

10 Connection technology: Attaching the cable harness
10.1 Attaching the butyl adhesive strip
In order to attach the cable harness, the insulating glass laminate is positioned - with the ECONTROL®
laminated glass facing down - on a level surface (roller table, cutting table or similar), as shown in Fig-
ure 18.
If the step edge is at the front facing the processor, the step edge can be viewed directly. In this case,
the Polyflex contact to the positive terminal (+) is on the left and
the Polyflex contact to the negative terminal (-) is on the right.
Figure 18: Positioning the ECONTROL® laminated pane (bottom) with a look at the step edge and
the contact tabs; the positive terminal is on the left and the negative terminal is on the right. The
shown black strips on the spacer consist of pre-cut butyl strips for fixing the cable harness; the
stickers with the plus and minus are below the contact tabs on the glass pane at the bottom
For easy distinction between positive terminal and negative terminal, stickers are attached to the outlets
of the Polyflex contacts. These stickers are located in the immediate vicinity of the Polyflex contacts on
the surface of the glass pane4 at the bottom (position 1). The stickers with the plus and minus can be
seen easily using a small mirror.
4 The stickers with the plus and minus cannot be fixed to position 4. Otherwise, they would interfere with
the placement of the spacer.

Figure 19: Sticker for the positive contact: Red PLUS with red circle on a white background
Sticker for the negative contact: Black MINUS with black circle on a brown background
In order to fix the cable harness, pre-cut butyl adhesive strips (Gerband 622; length approx. 6 cm; width
8 mm) are applied to the spacer (approximately in the centre) - see Figure 20. In case of “small” pane
dimensions, the distance between the butyl adhesive strips should be about 5 cm. In case of large
panes, the distance between the butyl adhesive strips can be increased to e .g. 10 - 15 cm.
It is necessary to ensure that the left adhesive strip goes 2 cm around the corner. Subsequently, the
white silicon paper can be removed from the butyl adhesive strips using a removing aid (e.g. tweezers).
10.2 Soldering the positive contact
First, one drop of tin solder is applied to the contact point of both Polyflex connections.
Following this, a heat shrink tube is pulled over the red wire (regarding cable type GV 07) or the white
wire (regarding cable type SVG 04) of the cable harness (positive contact). Then, the metal end of the
red or white wire is soldered to the left Pollyflex connection (positive contact). By pulling the cable gently,
the connection of the cable to the Polyflex connection can be checked.

Subsequently, the heat shrink tube is positioned centrally above the solder joint of the positive contact
and shrunk using a heat gun. Afterwards, the cable of the positive contact is fixed to the left butyl strip,
so that it is parallel to the spacer. Then, the left Polyflex connection is bent by 90° to the right, so that it
can be put in the step edge of the ECONTROL® laminated glass (see Figure 21).
10.3 Soldering the negative contact
Subsequently, the black wire of the connection cable (regarding cable type GV 07) or the brown wire
(regarding cable type SVG 04) is tin-plated. Afterwards, a heat shrink tube is put over the cable and
it is soldered to the right contact.
By pulling the cable gently, the connection of the cable to the Polyflex connection can be checked. The
heat shrink tube is pulled centrally over the solder joint, and shrinking is performed using the heat gun.
Subsequently, the right Polyflex connection is folded by 90°to the left (inverted L) and bent towards the
inside in the direction of the spacer, so that this connection is also positioned in the step edge of the
ECONTROL® laminated glass.
Attention:
Always applicable:

A taut cable routing is achieved by slightly pulling apart the two ECONTROL® connecting lines on the
cable. After soldering and shrinking the heat shrink tube, this cable part is fixed to the butyl adhesive strip
as well (see Figure 21).
The 4-wire cable with the connecting plug is fixed - towards the centre - to the butyl strips in such a way
that it protrudes approx. 15 cm from the insulating glass (see Figure 21 and Figure 22). For this purpose,
approx. 5 cm of the cable harness must be fixed to the butyl strips on the spacer. For the strain relief, a
butyl strip should be affixed over the cable.
ATTENTION:
The individual wires must be strung together in parallel and straight.
10.4 Fixing the connection cable and the temperature sensor
In order to fix the connection cable and the temperature sensor, the insulating glass laminate is rotated
counter-clockwise by 90°. Pre-cut butyl adhesive strips (Gerband 622; length approx. 6 cm; width 8 mm)
are applied to the centre of the spacer (see Figure 22). Again, the distance between the butyl adhesive
strips should be about 10 - 15 cm. It is necessary to ensure that some cm (e.g. 3 cm) are always led
around both edges at one corner of the butyl adhesive strips. Now, the white silicon paper can be re-
moved using a removing aid (e.g. tweezers).

Figure 23: Fixing the temperature sensor to the standing edge
The two cables connected to the temperature sensor are pressed parallel and tightly along the spacer
against the butyl adhesive strips. (ATTENTION: The formation of loops is not allowed).
Subsequently, the insulating glass laminate is rotated once more counter-clockwise by 90°. More butyl
adhesive strips are applied to the spacer at the standing edge (approx. up to the centre of the insulating
glass pane).
As a final step, the temperature sensor is pressed centrally (see Figure 23) into the angle between
spacer and ECONTROL® laminated glass and fixed using a butyl strip. A handling device made of plastic
(Teflon) may be useful for fixing the temperature sensor.
Attention!
In the angle between spacer and ECONTROL® laminated glass, the temperature sensor is to be at-
tached closely and fixed with a piece of butyl strip (see Figure 24).

10.5 Test of the temperature sensor and the connections
In order to test the ECONTROL® insulating glass, the ECONTROL
® pane testing device (hereinafter
referred to as ISOPOL testing device) is used. This device tests the temperature, the connections and
the polarity of the contacts. See: Operating manual ECONTROL® pane testing device.
Attention
Prior to the final assembly of the cable harness, an intermediate test must be performed using the ISO-
POL testing device.
If the test was successfully completed, the green LED of the testing device is illuminated. In this case,
wiring and sealing can be continued. If the test indicates an error (the red LED is illuminated and an error
is shown in text form on the display of the ISOPOL testing device), this error must be corrected before
continuing with other work steps.
Possible errors: Reverse polarity error, cold solder joint, defective temperature sensor
If the error cannot be corrected by the insulating glass manufacturer on his own, EControl®-
-Glas must
be contacted: Phone: 03741 / 148 20-100

11 Insulating glass adhesive
11.1 Material selection regarding the insulating glass adhesive
For reasons of compatibility with the ECONTROL® edge compound, only polysulphide, polyurethane and
silicone adhesives approved by EControl-Glas may be used as insulating glass adhesive (often also
referred to as insulating glass sealing).
In particular, this includes:
Insulating glass adhesives based on polysulphide:
THIOVER F by FENZI
NAFTOTHERM M82 by Kömmerling
GD 116 by Kömmerling
Insulating glass adhesives based on polyurethane:
GD 677 by Kömmerling
Insulating glass adhesives based on silicone:
DC 3362 by Dow Corning
DC 993 by Dow Corning
GD 920 by Kömmerling
Ködiglaze S by Kömmerling
11.2 Performance
The sealing must be performed in accordance with the plant specifications and the manufacturing speci-
fications of the insulating glass manufacturer.
The insulating glass bonding is to be carried out neatly and tidily according to the recognised rules. Par-
ticular attention must be paid to ensuring that the pane cable lies within the sealing compound and that
no air bubbles become visible (neither in the corners nor elsewhere). A bubble-free integration of the
temperature sensor must be observed in particular.
In order to avoid subsequent cleaning work, prevent insulating glass sealant from reaching the glass
surfaces.
The pane cable (type: AGV by LINK company) is to be lead out of insulating glass sealant centrally (see
Figure 25 and Figure 26) between the contacts.
When using insulating glass adhesives
based on silicones, it is essential to
consider that only the adhesives of
EControl-Glas mentioned on the left are
approved. Other adhesives based on
silicone or materials containing silicone
must not be used.
The processing information or process-
ing regulations of the adhesive manufac-
turers must be considered by all means.
In particular, this applies to the use of
the above-mentioned insulating glass
adhesives based on silicones which
were approved by EControl-Glas.

When carrying out the sealing (usually manually), the pane cable can be fixed to the counter pane (to
the outside surface) using a piece of crepe tape. In doing so, it must be ensured that the pane cable is
not fixed tautly, but slackly (without tension). After the hardening process of the sealant, the pane cable
is to be adhered to the dry sealing compound. This prevents the pane cable from being damaged at a
glass edge during subsequent process steps (e.g. packaging or transportation).
Note!
During the hardening of the sealing compound, the glass units must be stacked on a rack (Pay attention
to sufficient clearance between the glass units). When stacking and storing glass units on a rack, it must
be ensured that the outer and inner panes of the insulating glass does not slip or shift. When using sili-
cone as insulating glass adhesive (e.g. Dow Corning DC 3362 or DC 993), the instructions of the manu-
facturer (Dow Corning) must be followed.

With its thickness of 5.5 mm, the plug of the pane cable is thicker than common cork pads which are
used as spacers by many igu manufacturers. It must be ensured that the plug of the pane cable is not
jammed between two ECONTROL® insulating glass units and thus damaged when stacking the insulat-
ing glass units. This procedure also ensures that the insulating glass units, which are not yet fully cured,
harden in the 90° angle prescribed.
12 Gas filling
The gap between inner and outer pane is filled with a noble gas according to the plant specifications and
the standard operating procedures of the insulating glass manufacturer.
Note!
The standard ECONTROL® double insulating glass structure provides for a filling with argon.

13 Packaging, transportation, storage, shipment
13.1 In-house transportation
The in-house transportation and storage can be made on clean and dry usual glass racks (A- or L-
racks).
Attention!
Pay attention to edge damage. Edge cracks and serious conchoidal fractures impair the thermal stabil-
ity of the insulating glass units.
If the edge sealing of the insulating glass unit has not yet completely hardened, the insulating glass
structure must be secured against slipping of the individual panes!
If the ECONTROL® insulating glass pane is provided with a step at the standing edge, the ECONTROL
®
unit must necessarily be protected against shearing forces by means of suitable substructures!
Clean racks that are free from defects must be used.
13.2 Storage
Storing ECONTROL® insulating glass panes on usual glass racks in a hall is also possible, unless there
is the risk of direct sunlight.
Outdoor storage is not permitted!
Comment:
Due to different temperatures or light and shadow effects, direct sunlight may give rise to structures in
the ECONTROL® laminated glass, which may lead to irregular colouring. Such structures have to be
avoided.
13.3 Packaging and shipment
The shipment should preferably be made on standard glass racks (panes protected against falling and
standing on the edge) or in wooden crates.

When transporting and shipping with glass racks, the ECONTROL® insulating glass units must always
be covered or wrapped (with rear ventilation) with non-transparent tarpaulin or film. It must be possible
to remove this film from the glass units again without leaving residues. EControl-Glas recommends
the following film (see Figure 28):
Stretch film HSC standard, 20µm, black
(cast film, adhesion inside);
Supplier: Antalis Verpackungen GmbH;
http://shop.antalis-verpackungen.de
The ECONTROL® insulating glass units must be
transported with a closed truck.
Attention!
Direct sunlight to the insulating glass panes must
be avoided by all means.
Figure 27: ECONTROL® label (written in two
languages: German and English) which must
be filled in by the insulating glass manufacturer
and affixed to the internal glass pane, i.e. to the
inner pane of the insulating glass. The ECON-
TROL® label contains important information for
the subsequent identification and notes on the
installation of the insulating glass unit.
If the finished insulating glass units are delivered to the customer directly after the insulating glass pro-
duction, the ECONTROL® label must be affixed to the inner pane. The pane number and the dimensions
must be entered in the label!
At the building site, the ECONTROL® label serves as a unique identifier for the control of the ECON-
TROL® panes by the electrician.

When stacking the ECONTROL® insulating glass units, it is particularly important to ensure that the ca-
bles and their plugs are not situated between two ECONTROL® insulating glass units. As shown in Fig-
ure 28, the cables are fixed to the adjacent edge of the insulating glass using a piece of adhesive crepe
tape.
ECONTROL® insulating glass units must NEVER be stacked in such a way that the cable exits at the
standing edge. Otherwise, there is the extreme risk that the weight of the insulating glass unit damages
the cable and thus prevents the ECONTROL® insulating glass unit from functioning properly.
