Total PerformanceHigh performance is an essential ingredient for
all building components nowadays it is demanded by users and
required by current building regulations. Throughout ourhistory we
have kept ahead of both themarket and regulatory requirements to
offerglazing solutions that surpass even the mostdemanding
specifications, and our productsmeet or exceed all required
standards ofthermal performance. We have developedleading-edge
production techniques toensure that manufacturing efficiency
isoptimised, and environmental impact isminimised, and our
right-first-time qualitymanagement systems have been devised
tominimise waste and exceed the requirementsof current ISO 9001
standards.
Why Aluminium?Kawneer has been producing advanced glazing
solutions in this versatile material formany decades. Aluminium is
a near-perfectmaterial for architectural glazing products, and has
practical advantages over all otheravailable choices, including
inherentresistance to corrosion and very low whole-life costs.
Aluminium is also anenvironmentally friendly material and
possiblyone of the best options for energy savingwithin the
construction industry. In thebuilding sector vast amounts of
aluminiumare collected for recycling, with rates as highas 92-98%,
and more than 50% of the energyused in aluminium production comes
fromhydro-electric schemes.

PF Curtain Wall
IntroductionThe PF System is a mullion drained modularcurtain
wall system, which has beendesigned so that, when viewed
externally,the opening vents and the fixed lights havethe same
visual appearance.
The system consists of panellised frames thatare attached, as
either fixed lights, openinglights or panel areas, to the curtain
wallgrids. Each glazed panel has a visible faceof 28mm in width
which in combination witha 14mm recess between the panels, gives
anoverall sightline of 70mm. Alternatively, a
structurally glazed version of the system isavailable, giving
the facade an all glassappearance when viewed from the outside,with
only a 14mm recessed gap betweeneach pane. This thermally insulated
systemoffers many possibilities, with a wideselection of mullions
and transoms to suitmost practical requirements.
All this makes the PF System an attractiveand practical option
for many curtain wallingrequirements.

performance and designflexibility. The AA201 offers exactly
that.
It offers the advantage of unitised assembly givingthe building
team a unique set of benefits. Theseinclude factory fabrication to
ensure additionalquality control, rapid on site installation
withslimline design and flexibility. Unitised constructionenables
it to meet the demands of fast track workschedules and restricted
working conditions.Weathering is achieved by zone drained
pressureequalisation. The glazing provides a positiveweather seal
for high performance. The systemalso features the exclusive, high
performanceIsoPort thermal break.
The AA201 unitised system gives the specifier a
wide choice of styles to create individual andexciting building
facades. The AA201 canaccommodate spandrel infill materials

The Marine Operations Centre on Scotlandswindswept North Sea
coast is situated justtwo metres from the edge of the harbourwall.
The building has to withstand highwinds, cold winter temperatures
and a wet,salt-laden climate. And if that were notenough, the faade
was a complex, facetedoutward-sloping design.
The designers of this landmark building werethe Dundee office of
SMC Parr Architectswho opted for a striking modern take on
thetraditional Scottish lighthouse. The externalenvelope is partly
white reconstituted stonebut the greater part and the most
exposedpart is a bespoke glazed curtain wall.
We had come up with a bold concept and itwas essential to
progress the detailed designwith input from all parties the
installer and
the supplier as well as Sir Robert McAlpine,the main contractor,
said project directorDerek Reid of SMC Parr Architects.
This teamwork, with Kawneers specialprojects team supplying
design drawings andfabrication of the curtain wall, resulted in
aglazing solution that would accommodate thearchitects challenging
specification anddeliver the 270 visibility demanded by theclient,
Aberdeen Harbour Board.
The complex shape, and the fact that thewind-swept building
would be subject tohigher-than-average building movements,meant the
curtain walling had to be flexible inmore ways than one. Not only
did it need toaccommodate the curvature of the faade, ithad to be
capable of flexing with the rest ofthe structure.
The only solution was the Kawneer CWCTapproved AA110 curtain
wall system.
One of the biggest challenges for todaysarchitects and building
contractors is thereconciliation of material interfaces. Whereasin
traditional build the interactions betweenbrick, mortar and timber
are simple andpredictable, todays buildings incorporate afar
greater variety of materials that must bejoined without
compromising overall buildingperformance.
The most basic interface and often one ofthe most challenging is
that between thestructural frame and the building envelope.And the
biggest headache for designers andbuilders is how to cope with
differentialmovement.
The trend in prestige commercialdevelopment today is very much
towardshigh-rise steel framed buildings with a fullyglazed
curtain-wall faade and the pressureis therefore on system
manufacturers to riseto the challenge.
Kawneers solution to the increase in buildingmovement has been
to design and developa curtain-walling system in which each
glazedpanel can move more freely to a specifiedlimit within its
frame. The new AA110system features a deeper 65mm box sectionwhich
adds about 7.5mm to the rebatedepth. This extra depth has two
benefits:firstly, there is enough depth to increase theoverlap
between the aluminium frame andthe glazed unit, thereby meeting
therequirements for barrier loadings (that is, theamount of lateral
load the assembled systemcan withstand) and secondly, it
leavesenough extra space between the frame andthe glass to permit
movement within thesystem.
50mm systems are still very much theindustry norm that contains
the glass within a20mm-deep rebate with standard glass coverof
13mm.
Kawneers 50mm system, the AA100, is asuccessful example of this.
However, webelieve that is set to change with 65mmcurtain wall
systems becoming the norm withthe industry moving more and more
towardslightweight structures and larger expanses ofclear glass. If
the requirement is toaccommodate the inevitable buildingmovement,
and deliver the necessary barrierloadings, you simply wont be able
to use a50mm-wide box section.
The Marine Operations Centre is both aniconic structure for
Aberdeen and afunctional solution to the harbours
practicalrequirements. And although complex andchallenging, the
design has already won thebuilding a Civic Trust Award and
theadmiration of the architectural community.
