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.

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.
