INTRODUCTION INTRODUCTION
The composition of a sealed unit is shown by three figures (in mm) representing the following thicknesses:> The pane of external glass> The air or gas space > The internal pane of glass.
Example: 6/12/4 indicates a pane of external glass 6 mm thick, a spacer measuring 12 mm and an internal pane of glass 4 mm thick.
▼ DouBLE-GLAZING coMpoNENtSDouble glazing comprises the following elements:> Two panes of glass> A spacer to determine the width of the space between the
two panes of glass; this may either be assembled with corner mechanisms, bent or welded. The spacer may be made of steel or aluminium. Spacers made of synthetic or composite materials (“warm edge”) are also available. A synthetic spacer is used for specific applications
> The space between the two panes of glass may be filled with air or with another gas injected during the manufacturing process (argon or krypton)
> An initial waterproof barrier made of butyl and positioned on the side of the spacer which is in contact with the glass. It is designed to prevent moisture from entering the air or gas space
> A second waterproof barrier or seal linking the panes of glass and the spacer. This is designed to ensure that the assembly is mechanically stable; the seal is made of either polysul-phide, polyurethane or silicone. Only silicone is suitable if the seal will be exposed to solar radiation or in some specific applications
> A desiccant placed in the spacer to dry out (adsorb) the gas trapped at the point at which the glass touches and to adsorb steam which may enter the unit over time through the outside seal.
▼ INSuLAtING GLAZING ASSEMBLIES – GENERALThese are sealed units comprising two panes of glass which, having been assembled and sealed in the factory, are separated by a closed hermetic space containing air or an insulating gas. The main aim of such assemblies is to use the insulating prop-erties of the air or gas space to lower the thermal transmittance (Ug value) of the glazing. The latter’s insulating properties can be further enhanced in various ways (low-emissivity coatings, gas and so on). The unit may be double- or triple-glazed.

INTRODUCTION
How well the desiccant and the waterproof barriers function will determine how the long the unit lasts; if the desiccant becomes ineffective or if the seal is no longer hermetic, condensation will form inside the unit and it will have to be replaced.
AGC offers all possible joint technologies (PU,PS, Silicone) and spacer bar types (alu, steel Warm E). AGC also offers the unique possibility to combine silicone with an argon filling or even a Warm E spacer.
▼ tHE AGc GuARANtEEWhen provided by AGC Glass Europe, DGU are branded Ther-mobel. The guarantee specifies that vision through its insulating glazing will not be affected by condensation or dust on the inside of the unit. This guarantee does not cover breakage or cracks in the glass or replacement windows which have become defective once the guarantee period on the original glazing has expired. Please see duration, terms and conditions of the guarantee.
▼ HEIGHtDouble-glazing units to travel through or to be fitted 800 m higher in relation to the production location will either be lev-elled out in advance in the workshop or will be fitted with a levelling mechanism. It is important to specify this when placing your order.
▼ MuLtIpLE FuNctIoNSBy varying Thermobel’s components, other functions can be obtained which will complement the glazing’s thermal insula-tion properties: enhanced thermal insulation, solar control, sound insulation, safety and decoration.
THERMAL INSULATION
▼ INtRoDuctIoNThere are two types of assemblies providing thermal insula-tion: standard thermal insulation (Ug > 2) and enhanced thermal insulation (Ug ≤ 2):> standard thermal insulation: consists of two panes of Planibel
glass > enhanced thermal insulation: in double glazing or triple
glazing with one or two coated glasses.
In all cases, the overall Ug-value of the glass can be enhanced by:> using neutral and transparent coatings applied to the glass.
These coatings are called “low-emissivity” or “high-perform-ance” coatings
> making the spacer as large as possible> adding a Warm-E type interlayer between the two panes of
glass> adding a noble gas.
In double or triple glazing, the space between the panes of glass is filled with air or a thermal gas.

The combination of its solar factor and its Ug value makes Planibel Top 1.0 an excellent glazing solution for the residential market in southern Europe, as it provides good solar protection in the summer and effective domestic insulation in the winter.
Planibel Top 1.0 is also a solution that is recommended in the commercial building sector, since some “cooling” is needed because of overheating inside such buildings (due to heat from the human body, office equipment, etc.). Combined with a solar control glass (Stopsol, Sunergy), Planibel Top 1.0 glazing can enhance solar protection in this type of buildings.

▼ REcoMMENDAtIoNS To achieve the best appearance and ensure optimum perform-ance:> The external high-performance glasses must be the same
thickness> The two spaces between the sheets of glass must be the
same width> The middle glass must be Clearvision extra clear glass.
▼ BENEFItS> New Planibel Tri coating – the best choice for low-energy or passive houses
Planibel Tri has been specially developed for triple glazing assemblies that meet the special requirements of passive or low-energy houses (where a Ug value of less than 1 and a solar factor of over 60 are recommended). As well as a high-performance U value and a high level of light transmission, neutral Planibel Tri glazing offers the benefits associated with a high solar factor and so promotes major free solar gains, optimising the overall energy efficiency of the house and reducing heating bills. For an accurate calculation of potential fuel gains that can be made in new buildings or in renovation, see the IFT Rosenheim study*
on www.yourglass.com.

> Surface temperature at near-ambient temperatureSince triple glazing has very low U values, the temperatures of the glass facing the inside of the building are very close to the ambient temperature inside the building.
This is shown in the table below:
Types of triple glazingSurface temperature of the inside pane
- 10°C / + 20°C* 0°C / + 20°C*

0.7 or 0.7 Kr 17.4 18.3
0.6 or 0.6 Kr 17.8 18.5
* Int. T° / Ext. T°.
> Reduced risk of condensationThanks to triple glazing’s high-performance Ug value, the inside pane of the glazing assembly has a temperature close to the ambient temperature. The risk of condensation is therefore even lower than with high-performance glasses with Ug values of 1.1 and above.
At the same relative humidity, triple glazing slows down the for-mation of condensation on the glass facing the inside of the building.
▼ coMMENtS> Given the high performances of triple glazing, this glass must
be used in a building for which the various parameters (such as insulation of all elements, thermal bridges and natural or mechanical ventilation) have undergone prior evaluation in order to obtain an optimal quality construction providing a healthy and pleasant atmosphere inside the building
> Since triple glazing is a highly insulating glass, it is possible that condensation will appear on the glass facing the outside of the building at certain times of the year. This occurs in very specific humidity and temperature conditions. The condensa-tion will disappear of its own accord during the day as condi-tions change.

STOPSOLGlass with a solar-control reflective pyrolytic coating In single panes or insulating glazing
STOPSOL
Tasmajdan, Belgrade, Serbia Montenegro - Architect: Partner Inzenjering - Stopsol Silverlight PrivaBlue
▼ DEScRIptIoN > Glasses with a hard A-type pyrolytic coating according to
EN 1096-1, which can be used in a variety of processing options including toughening, bending and silk-screen printing
> The Stopsol brand comprises three types of coatings: Classic (amber look), Supersilver (silvered look) and Silverlight (bluish look). These coatings are generally available on clear glasses and some coloured glasses
> The coating may be applied in position 1 or 2. This will affect how the glass looks, particularly coloured glass
> Can be assembled in insulating glazing with a low-emissivity Top N+ glass
> Range of spandrels available in monolithic glass and double glazing
▼ BENEFItS > Reflective glasses providing privacy and visual comfort> Multiple combinations of solar-control and light-transmission
levels and various colours> These glasses offer architects limitless creativity: one range
can be used for all applications.
▼ coMMENtSCoating #1 Coating #2
Aestetics exterior
On clear glass: always reflective
On coloured glass: very reflective On coloured glass: not reflective
In #1 for heat-strengthened, toughened or enamelled Stopsol, optical distortions due to thermal treatment are more visible than would be the case with non reflective glasses
Aestetics interior
The reflection of the glass and its “mirror” aestetics are important when the coating is in #2
Look Look of the glass stands out Colour of the base glass stands out
Absorption Higher if the coating is applied in #2 and if the base glass is coloured. Can be toughened if necessary
Maintenance Maintain regularly – see mainte-nance guide at www.yourglass.com
> Stopsol coatings are not low-emissivity> We recommend using the same thickness of glass throughout
a façade, especially when the Stopsol coatings are applied in position 2.

▼ DEScRIptIoN The level of acoustic performance of an insulating glazing depends on:
The total mass of the glass
The thickness of the glasses used
Whether laminated Stratobel or Stratophone glass is used
Laminated safety glasses In single and double glazing
▼ INtRoDuctIoN Safety as a concept covers a wide area and comprises several aspects:> Protecting persons against injuries caused by:
· Broken and sharp pieces of glass
· A fall (defenestration).
Where the risk of injury alone is to be avoided, the main factor to bear in mind is the breakage pattern of the glass. Care should be taken to avoid the glass breaking into pieces which could cause injury.
If protection against defenestration is also a concern, it is important that the glass is not obliterated completely if broken.
> Protecting goods and safety against burglary and vandalism of private homes, shops and offices. In this case, the glass should remain in place and should prevent burglars/vandals from entering
> Safety against firearms> Safety in the event of an explosion.
Only a small number of glass products meet the breakage, defenestration and resistance criteria detailed above.
There are two main families of safety products available from AGC:> Thermally toughened products and thermally toughened
Heat Soak Tested (HST) products (for details of this range please see the chapter entitled “Heat-treated glasses”)
> Laminated products such as Stratobel and Stratophone.

PVB (polyvinylbutyral) or EVA (ethyl vinyl acetate) interlayers> The structure of the assembly and the number of PVB inter-
layers determines the level of safety in terms of protection of individuals and property and protection against burglary, firearms and in the event of an explosion; can also be assem-bled with polycarbonate

▼ INtRoDuctIoN Glasses may be heat-treated to enhance their resistance to mechanical and thermal shocks.> There are three types of glass:
· heat-strengthened
· thermally toughened
· thermally toughened and Heat Soaked.> Breakage pattern:
· into small blunt pieces
– of thermally toughened glass means that they may be considered safety glasses
– of thermally toughened glass and which may or may not be Heat Soaked
· into large sharp pieces of heat-strengthened glass means that it cannot be considered safety glass.
HEAT-STRENGTHENED GLASS
Typical breakage pattern of heat strenghened glass
▼ DEScRIptIoN > Like thermally toughened glass, heat-strengthened glass is
treated using a method of controlled heating and cooling which locks the surface of the glass in a state of compres-sion
> This method produces a glass with a bending resistance greater than that of annealed glass but less than that of ther-mally toughened glass since the glass is cooled more slowly. Heat-strengthened glass does not require heat soaking
> Virtually all types of glasses in the AGC range may be heat-strengthened: clear and coloured Planibel, Stopsol, Sunergy, Imagin and so on
> Some types of glasses with magnetron coatings are also available in a heat-strengthened version; this requires a few adjustments to the thermal-toughening processes
> Heat-strengthening can be combined with silk-screen printing or enamelling.

> Use: single glazing, insulating glazing, laminated glazing and so on – primarily for applications where:
· the risk of the glass breaking due to thermal shock (particu-larly with solar control glasses or those with a higher level of energy absorption) is too high
· the resistance of the glass to breakage by bending of a maximum of 70 N/mm² is considered sufficient.
> Once treated, heat-strengthened glasses cannot be sawn, cut, drilled or processed
> Heat strengthened glass complies with standard EN 1863.
▼ coMMENtS > Spontaneous breakingHeat-strengthened glasses do not suffer spontaneous breakage due to nickel sulphide inclusions. Heat-strengthened glasses do not need to be heat-soaked in advance.
> Optical performance· Optical distortion
The thermal toughening process causes the surface of the glass to distort in two ways:
- overall bend of 3 mm/m* - localised bend of 0.3 mm/300 mm* * values for heat-strengthened glass using the horizontal process.
· Interference Heat-strengthened glasses cause interference in the same way as thermally toughened glass.
▼ pERFoRMANcE> Heat-strengthened glass:
· is more resistant to thermal stress than annealed glass. It can withstand differences in temperature of approximately 100°C
· more resistant to breakage due to bending (70 N/mm²) than annealed glass
· breaks into large sharp pieces which can cause injury.
Accordingly, heat-strengthened glasses are not safety glasses. Heat-strengthened glasses break in a crazed pattern.> Magnetron coatings which can be thermally treated must be
heat strengthened to achieve the stated performance (frag-mentation, optical, Ug value)
> The light, thermal and energy performance of thermally toughened glasses is exactly the same as that of the same annealed glass.
▼ FINISHING > Edge finishing The following edge finishings are available for heat-strength-ened glasses:
· Arrissed edges
· Ground edges but some bright areas permitted
· Ground edges but – no bright areas
· Polished edges.
For buildings, the heat-strengthened glass will be supplied as standard with arrissed edges but depending on the require-ments of the particular application, a different finish may be possible.
Ground polished edges are normally only destined for non-building applications.

THERMALLY TOUGHENED GLASSES
Typical breakage pattern of thermally toughened HST glass
▼ DEScRIptIoN> Thermally toughened HST glass treated using a method of
controlled heating and cooling which locks the surface of the glass in a state of compression. Once it has been tough-ened, the glass is placed in a furnace where it undergoes a specific heating cycle which causes some glasses containing inclusions or impurities to break prematurely. This is known as heat-soak treatment
> Virtually all the glasses in the AGC range can be thermally toughened and heat-soaked: clear or coloured Planibel, Stopsol, Sunergy, Imagin, etc.
> Certain types of magnetron-coated glasses can also be toughened; this requires some adjustment to the tough-ening procedures
> Thermally toughened heat-soaked tested glasses can be combined with silk-screen printing or enamelling
> Use: in single glazing, insulating glazing, laminated glazing and so on – primarily for applications where the following are required:
· Greater resistance to mechanical shocks (glass doors, glass units with punctual settings, etc.)
· Greater resistance to thermal stresses (glasses exposed to solar radiation with possible shadows which cause stresses in the glass, etc.)
> Breaks into small, blunt pieces as per the relevant require-ments. Thermally toughened glass is always a safety glass in certain applications. Its usage always depends on the applica-tion and local regulations
> Please contact your local supplier for the relevent classifica-tion
> Toughenable Magnetron coatings should be toughened to achieve the desired performance (fragmentation, optical, Ug value)
> The light, thermal and energy performance of thermally toughened glasses is exactly the same as that of the same annealed glass.
▼ FINISHING> Edge finishing Toughened glasses can be supplied with several edge finish-ings such as:
· Arrissed edges· Ground edges but some bright areas permitted· Ground edges but no bright areas · Polished edges.
In buildings, toughened glasses will be delivered with arised edges as standard but depending on the type of application, other finishings can be supplied on request.
> Other possible finishings· Holes· Notches· Cutting.

· Greater protection against the glass breaking, thereby reducing the risk of injury.
There is still a risk that a thermally toughened glass which has not been heat-soaked may spontaneously break. It is up to the client to assess whether heat-soak treatment is required depending on the type of application in which the glass is to be used.
> Glass which has been thermally toughened and heat-soaked is much less likely to break spontaneously
> Once toughened, heat-soaked glasses cannot be sawn, cut, drilled or processed
> Thermally toughened glass complies with EN 14179.
▼ WHY cHooSE tHERMALLY touGHENED HSt GLASS?The glass may contain nickel sulphide inclusions (NiS) which can vary in size from a few microns to a few millimetres. These inclusions have a special crystalline structure which is different at low (larger volume) and high (smaller volume) temperatures. In the case of a thermally toughened glass, the NiS acquire their stable structure at a high temperature when the glass is heated to approximately 650°C. The rapid cooling involved in the toughening process does not give the NiS time to acquire their stable low-temperature structure before the glass solidi-fies. The glass is therefore processed at its operating tempera-ture. During this time, the increase in the volume of the NiS inclusions can cause the sheet of glass to break spontaneously once it has been installed.
To limit the risk of breakage, thermally toughened glasses can be heat-soaked. This entails placing the glass in a furnace at a constant temperature for a specific period to process the NiS. Any breakage caused by critical NiS crystals will therefore occur during heat soaking.

▼ AppLIcAtIoNS Colorbel must be installed in front of a dark, unlit or slightly lit opaque surface so as to ensure regularity of appearance across the entire surface. For light colours, the underlying base must be uniform. For assemblies that involve gluing, it is necessary to check that the glue does not show through.
Interior Yes
Exterior
Yes – All applications in architecture and construction or renovation for spandrels.- Colorbel lends itself to various glazing methods: rabbets, clamping, gluing
(structural glazing), bolting (point-fixed structural glazing).- It can be used in ventilated or non-ventilated spandrels.- Enamelled glass is not meant to be backlit.- The enamelling can show deformations in reflected images typical of all
types of toughened glazing.- The colour may vary slightly depending on the thickness of the glass. Con-
sequently, it is preferable to use a single thickness across the entire façade.

STRUCTURAexternal point-fixed structural glazing system for glazings and structural components
System of single, monolithic or laminated glazings allowing maximum light transmission and a low level of exterior light reflection. Very large sheets of glass can be used safely and securely depending on external constraints.
Structura Vision has three variants:> Vision G: knee-jointed system: capable of bearing heavy
weights and stresses and significant differential movements – for façades and roofs
> Vision R: knee-jointed system: capable of bearing average stresses – for roofs and facades
> Vision V: simplified system: capable of bearing light stresses – mainly for interior vertical partitions.

▼ StRuctuRA DuoInsulating double-glazing systems with monolithic or laminated components. Recommended when a high level of thermal and solar performance is required.
Full manufacturing process handled by AGC to ensure optimum quality.
▼ StRuctuRA SuppoRtThe logical back-up for Structura Vision and Duo point-fixed structural glazings, in Structura Support the metal and opaque structures are replaced with transparent ones: Structura Sup-port allows glass fins and beams to be incorporated safely and securely into structural glass.
This can be used to create real “all-glass” façades.
Zepter, Warsaw, Poland - Architect: Zinosco and Gader - Stopsol Supersilver Dark Blue structural glazing
▼ DEScRIptIoNThis technique can be used to create an “all-glass” façade in which the actual structure is hidden behind the glass.
Glazing in which the silicone seal is designed to transfer the stresses and to be resistant to UV radiation since there is no rebate on the edges.
The structural glazing façade technique can be used with single panes of glass, coated or non-coated double glazing enamelled glass, etc.
▼ BENEFItS Structural glazing can be used to create all-glass façades.
Due to its design, structural glazing also provides: > a good level of waterproofing> excellent sound insulation> an easy-to-clean surface> protection for the load-bearing structure.

▼ GLASS coMpoNENtS We generally recommend using glasses at least 6 mm thick. The glasses used are either single or double glazing in which at least one edge remains visible and exposed to radiation. For this reason, the seal must be made of silicone.
Float glass – single glazing Yes – See Planibel and Planibel coloured
Coated float glass – single glazing
Yes – See solar-control glasses with a pyrolytic coating which can be used in single glazing units - Stopsol – Sunergy. Edge stripping is not necessary.
Insulating glazing
- The height of the silicone seal is higher than that of ordinary insulating glazing and will be calculated to resist depression to wind on the glass
- For safety reasons, the interior glass must never be toughened. This is to avoid the second pane of glass disintegrating if the interior pane breaks
- Where necessary, the interior glass will be strengthened- When using Magnetron coatings (Stopray, Top N+,
Energy N), the coating must be edge-stripped to a higher level than that of a traditional glazing since the silicone structural glazing seal is positioned higher than a normal seal. This will cause a larger dark edge to be visible from the outside
- When dealing with ”stepped” glasses, the visible height must be edge-stripped
Spandrel/enamelled glass Yes – Check with the silicone supplier that the structural seal adheres to the enamel
