Metal window-systems with synthetic bridges are no longer up to date
In conventional metal windows the outer metal shell is connected to the inner one (aluminium or
steel) by synthetic bridges. Regarding thermal insulation this technique is no longer up to date
(illustration 1). It is no longer possible to lower the heat transfer coefficient to an acceptable level
with this technique or by increasing the gap between the profile shells to cover the synthetic
bridges. Even inserting additional, complicated and expensive measures at a latter point such as
inserting insulating materials for example or special sealing profiles into the profiles delivered by
the manufacturer cannot lower the U-value to under 1.8 W/m²K. Also these additional measures
cannot be thoroughly checked by the investor.
The better window-system by PURAL
PURAL GmbH & Co. KG has found a much more efficient way to cope with the increasing
demands of thermal separation and the relevant thermotechnical qualities of the metal profile
frame with its products PURAL ALUMINIUM, PURAL eco ALUMINIUM and PURAL STAINLESS
STEEL (illustration 2 and 2b).
This efficiency can be achieved using a polyurethane integral hard centre as the heat shield, which
thermally separates the outer and inner profile shell with an appropriate volume and keeps them
firmly together. The related thermotechnical qualities of this profile frame are comparatively
unmatched.
Only in connection with the heat shield all advantages of a metal-window/door system compared
to other materials become apparent. The systems PURAL ALUMINIUM, PURAL eco ALUMINIUM
and PURAL STAINLESS STEEL do not require any thermal insulation measures. With the
outstanding calculated low thermal transmittance value for a blind frame/window sash combination
of only 1,0 W/m²K and 1,4 W/m²K not only a vast amount of energy can be saved, but also the
people living and working in these rooms experience a superior comfort level.
PURAL-INFO 2
The isothermal characteristics of PURAL ALUMINIUM, PURAL eco
ALUMINIUM and PURAL STAINLESS STEEL windows prevents building
damage
In conventional thermally separated metal windows (aluminium or steel) the thermal insulation
value of the window frame is considerably lower than the glazing´s and the insulated transitions to
the building. Therefore these systems tend to condensate on the inner window profile surfaces
and at the transition points. This can lead to damage and furthermore be the cause of mildew and
germs, which is a serious hygienic concern in buildings, where people live and work. Low Ufactors combined with the metal profile´s inner surface temperature matching room temperature,
can ensure that frame and glass surface are structural-physically homogeneous and of nearly the
same insulation quality. This prevents condensation and naturally the cause of mildew and germs.
Due to the favourable isothermal characteristics within the heat shield (illustration 3 and 3b) the
window systems with the polyurethane centre can be fitted facade flush without objection unlike
other metal window systems with insulation bridges. Residue on the window sills and the
connected fouling of the facade can be avoided. Through this, cleaning and maintenance can be
kept to a minimum. It is only logical to conclude, that the amount of cleaning required in the room
can be reduced, due to the lack of condensation and dirt.
PURAL ALUMINIUM, PURAL eco ALUMINIUM and PURAL STAINLESS STEEL
windows ensure more comfort
With conventional thermally separated metal window profiles the measurable temperatures on the
inner profile surfaces differ from the room temperature in the winter. Through this a chill emerges,
that can be perceived as a pseudo draught and cause people living and working in those rooms
great discomfort.
With the window and door systems PURAL ALUMINIUM, PURAL eco ALUMINIUM und PURAL
STAINLESS STEEL the metal shells rest firmly and without a cavity on the heat shield. In
conjunction with the high thermal insulation value of the polyurethane centre the inner surface
temperature matches room temperature even at low outside temperatures. Therefore no chill
emerges. - No pseudo draught. Even being near the window feels comfortable.

PURAL ALUMINIUM, PURAL eco ALUMINIUM und PURAL STAINLESS STEEL
profile manufacturing
Manufacturing sandwich profiles, 6 m long, outer and inner shells of aluminium and stainless steel
are joined with CFC-free polyurethane foam in the profiles. The resulting massive, rigid and highly
insulating heat shield contains all the functional slots to take seals and fittings. The metal shells of
the thermally insulating window and door systems are coated with the desired colour before the
joining, whereas it is possible to choose different colours for inner or outer profiles. The aluminiumand stainless steel profiles can also be ground decoratively, also with a colour coating of course.
Advantages during the basic production of PURAL ALUMINIUM, PURAL
STAINLESS STEEL – windows and doors and PURAL eco ALUMINIUM
windows
One of the general advantages of this system is the further cost-effective processing of the profiles
to the elements. Assembling the window and door profiles to frame elements is quite simple and
fast, because it requires neither special machines and tools nor assembling appliances - the only
required tool is a rubber hammer (illustration 4). The low processing costs follow from the
frame´s smooth assembly via self claw-fastening corner connections, as well as the fittings´ easily
bolting into the hard polyurethane centre. The angled flat corner connections of the aluminium
systems PURAL ALUMINIUM and PURAL eco ALUMINIUM are simply pressed into the existing
cavities. The stainless steel clips embedded in the corner connections claw-fasten tightly to the
cavitiy´s aluminum wall. The round corner connections in the stainless steel system PURAL
STAINLESS STEEL are simply pushed in with adhesive into the round holes placed by a drilling
gauge and also claw-fastened with stainless steel clips in the polyurethane centre. The holohedral
mitre cut of both systems is provided with polyurethane adhesive before joining the mitre. By
bonding the holohedral mitre the corner connections are unlike all bridged profiles absolutely
airtight and free of convection. With this special mitre assembly technique - without welding - even
the stainless steel profiles´ surface can be ground decoratively in an economical manner before
further processing into bars of 6 m in length.
PURAL-INFO 4
Furthermore welding is obsolete, as is the welded mitres grinding and dressing, which is normally
required with all steel and stainless steel systems. This makes the system PURAL STAINLESS
STEEL especially economical.
The profile joints look impeccable unlike the conventional welded stainless steel mitres and do not
display the common unappealing reflections resulting from the retouching as described above
(illustration 5).
The thus manufactured frame elements PURAL ALUMINIUM and PURAL eco ALUMINIUM
guarantee a high technical standard, long life-cycle and easy serviceability.
Furthermore, with conventional metal window systems a considerable amount of energy can only
be saved by using expensive, energy efficient glazing. Depending on the building requirements,
this is often superfluous with the PURAL systems. Yet saving energy is not the only parameter:
PURAL ALUMINIUM, PURAL eco ALUMINIUM and PURAL EDELSTAHL
window systems combine all required qualities
Altogether in commercial and public buildings such as hospitals and schools where many people
live and work, following qualities in window systems are of vital importance.
• energy saving
• long life-cycle
• little maintenance
• hygiene
• cleaning
• comfort
The systems PURAL ALUMINIUM, PURAL eco ALUMINIUM and PURAL STAINLESS STEEL
fulfill these qualities unlike conventional metal window systems to its full extent.

General qualites of PUR - hard stuctural foams
Rigid polyurethane foam is a thermosetting synthetic, which can be processed at a packing factor
of > 2 into hard structural foam – formed components. Due to the structural density allocation,
starting from a foam centre to a nearly compact outer layer, this possesses outstanding
consistency despite a comparatively light weight, and can therefore be used in many ways,
especially as casing and frame elements.
At the same time, the polyurethane´s excellent material properties such as
•
•
•
•
optimal durability
good chemical and biological resistance
physiological harmlessness
mainly odour-free
Come into use as do the good formed component properties of PUR- hard structural foam
•
•
•
•
high rigidity
excellent resistance to thermal distortion
good surface quality
superior insulation property
Basic raw materials
Polyurethane hard foams are usually manufactured from to liquid components by the PU-fabricator
in an existing mould.
Firstly pure MDI, which is industrially offered on the global market as polymeric MDI, and secondly
an MDI isomer mixture is used. On the other hand a polyol mixture including catalysts, stabilizers
and other processing aids are added in order to finally achieve the required component properties.
Normally, processing takes place in a 2-K high-pressure factory, mixing the components into the
desired mix ratio and batch dose and pouring it into the particular mould.
Physiological harmlessness
Rigid polyurethane foam, manufactured according to regulations, does not give off physiological
relevant chemical substances. In particular, they are free from formaldehyde and heavy metals.
PURAL-INFO 6
Fire
With the appropriate adjustment the rigid PU foams can be classed as B2 according to the
German fire code DIN 4102. In the case of a fire, the fume discharge is of a similar composition
comparable with the burning of wood, along with a matching oxygen supply.
The PURAL-profile´s metal finish, towards the inner and outer area, makes it possible to use in the
combustion zones across the floors.
Rigid polyurethane foam and environment, ecological aspects
In the „Life-cycle-analysis“ a product is regarded "from the cradle to the grave".
Applying this to PUR-hard foam the criteria energy input, energy conservation and pollutant
releases crucial in the three phases of a product: manufacturing, utilization and recycling.
Production
Crude oil or renewable resources such as sugar beets, maize, potatoes and recently also
recyclates from synthetics are usually the raw the material base in the production of rigid
polyurethane foam insulants. Here from the two main components polyol and isocyanate are
manufactured.
In the case of rigid PU foam crude oil is not burnt for heating purposes, but used to
manufacture an insulant, helping to save energy over the course of 30 to 50 years.
One cannot imagine a more sensible way of using oil than using it to "save oil".
Yet looking at today´s crude oil consumption,
about 70 % are used for heating purposes and only
about 4 % for the production of synthetics
about 12,5 % for fuel
about 3,5 % for chemicals and
about 10 % for other purposes.
From the synthetics only a very small fraction (about 5 %) are used for the production of rigid PU
foam insulants.
Nowadays, water is used as a propellant, which produces CO2 as an encased cell gas during the
chemical reaction with isocyanate.
PURAL-INFO 7
Emissions during the production of rigid PU foam
The industrial polyaddition procedure is applied in the production. The very low MAC value for this
MDI of 0.005 ppm isn´t under-run at any point. This has been confirmed by various
measurements.
Production of rigid polyurethane foam boards
During sawing, grinding and milling, physiologically harmless rigid polyurethane foam dust is
produced. Working on an industrial scale, the manufacturer has to protect himself – as is done
against all kinds of dust – by putting on an appropriate dust mask. (inhalation protection leaflet by
the chemical industry´s government safety organization). The airborne dust concentration (general
dust threshold according to the technical regulations for dangerous substances TRGS Nr. 900 and
901) must not go beyond these values.
Ø 10 mg/m³ (measured as inhaled fraction)
Ø 3 mg/m³ (measured as alveolar fraction)
Extraction systems are also required to prevent dust deposit in enclosed rooms avoiding dust
explosion safely (as with saw dust).
Health criteria
Rigid PU foam produced following regulations doesn´t give off any physiological relevant amounts
of chemical substances, esp. formaldehyde dispense hasn´t been observed.
Recycling
Rigid PU foam can be recycled. Nowadays adhesive hard board can be made from process
waste. Some manufacturers use waste also to make recyclate polyols by means of glycolysis,
which are directly used again in manufacturing.
PUR hard foam waste that can´t be recycled is put in household waste combustors for thermal
recycling.
PURAL-INFO 8
Consistency
Rigid PU foam is resistant to substances that usually occur in building. It is resistant to age and
biologically non-degradable, for example by mildew.
Rigid polyurethane foam is resistant to solvents in practical applications such as adhesives,
bitumen coatings and pastes, wood preservatives and liner sheets. It has no affinity to softening
agents, therefore monomeric softeners from roof sheetings for example don´t move into the foam.
Furthermore rigid PU foam is resistant to fuels, mineral oils, diluted acids and alkaline solutions
and also not affected by emissions or an aggressive industrial atmosphere.

Construction instruction
Post-latch - facade (width perspective 50mm)
Thermally insulated post-latch constructions of extruded aluminium profiles with a width perspective of 50 mm.
System: PURAL pro Plus F50
Classification / Grading:
Uf - Werte according to prEN 10077 - 2
Exposure class C according to DIN 18055
Airtightness according to DIN prEN 12152, class A 4
Resistance to driving rain according to DIN prEN 12154, class R 4
Applicable to vertical or slanted aluminium glass facades on one floor or multistorey up to 100 m installation height.
Layout executed straight or polygon, furthermore used for manufacturing glass roofs, pyramids and conservatories.
The post-latch facade is construed in such a way, that post and latch are made from the same profile cross-sections.
It´s not necessary to catch the latch profiles, while the patented glazing rebate drainage takes place via the latch´s
synthetic insulant into the drainage slot of the vertical bolt. The latch is attached via an especially patented joint
technique. This is laid out in such a way, that the latch is automatically pressed on to the post, closing the connection
joint between latch and bolt.
Processing advantages
Post and latch profiles with inner edge radius of maximal 0,5 mm for a visually flawless latch attachment at the same
building depth. At the same time the inner surface of the latch profile displays the exact same level section.
The inner glazing seal with post and latch profiles have the same width perspective.
The aluminium post and latch cavities are prepared for the insertion of half-finished profiles (pipe - or longitudinal
cross section) in order to create joint and fix points and to raise the static properties.
Glazing rebate air ventilation respectively steam pressurization via the bilateral drainage slots in the posts, ventilation
takes place via each of the four field corners.
Outer glazing seals are available as single seals alternatively with vulcanized end pieces.
Outer pressure strips optionally bolted visibly or hidden; visibly bolted pressure strips are available as U-profile or
longitudinal profile. Cover jackets for masked bolting are available for different installation heigth.
