Why use VMZINC facades?
Zinc is among the most sustainable metalsused in construction today and was first usedfor roofing and gutters in large Europeancities at the beginning of the 19th century.Batten cap zinc panels were used formansard roofs but towards the end of the20th century architects began to use zinc as away to clad facades. Over the past 20 yearsVMZINC has developed a range of facadesystems that vary in dimension, joint size and type.
All VMZINC facade systems can be used fornew build and refurbishment alike and incombination with many other buildingmaterials. As with all VMZINC productsexceptional durability, very limitedmaintenance and a wide range of beautifulfinishes are offered by VMZINC facades.

Sustainable performance
4 Facade
Facade
Low energy used in the
manufacturingprocess
VMZINC rolled zinc products are used inconstruction industries throughout the worldfor their sustainability, distinctive appearance,and low maintenance requirements. As withroofing and rainwater systems, manufacturingprocesses for our facade systems presents alow environmental impact, particularly withregard to energy expenditure.
VMZINC facade systems benefit from zinc’sself-protecting patina which develops as aresult of exposure to water and carbon dioxide.Over the last 50 years the quantity of sulphurdioxide in the atmosphere has been greatlyreduced. SO2 being the key agent of corrosionmeans that corrosion rates are now less than1μm per year on facades. With an initialthickness of 1mm, the estimated life span of azinc facade is well over a hundred years.
95% of old rolled zinc recovered every yearin Western Europe, currently estimated at100,000 tonnes, is reused. This representssavings in mining resources of between 1 and 2 million tonnes.
VMZINC undertakes Life Cycle Analysis (LCA)tests on its products and publishes Environmental Product Declarations (EPDs),such as BRE Environmental Profiles, availablefrom our website www.vmzinc.co.uk andwww.greenbooklive.com. These provideusers with comprehensive, reliable andtransparent information on relevant environmental characteristics. Theinformation is also used by VMZINC as thebasis for its eco-design approach.
Low corrosion,long life
Recycledmaterial
Comparative energy expenditure in manufacture
Compared with other metals, very little energy is needed to manufacture zinc metal from ore –less than half the consumption of copper and stainless steel and less than a quarter of that used foraluminium. CO2 and other greenhouse gas emissions are also, therefore, proportionally less.

Environmental profiles measure theimpacts of a construction material, productor building system throughout its life, notonly during its manufacture, but also itsuse in a building over an 80-year period.This includes its extraction, processing, useand maintenance and its eventual disposal.
VMZINC has been audited and reviewed byBRE Global. The Life Cycle Assessment (LCA)modelling derives a Certified EnvironmentalProfile and a Green Guide rating has beenproduced.
A wide range of zinc roofing and claddingsystems has been audited with thesystems receiving a Green Guide rating ofup to A+. These profiles can then beapplied to the BREEAM (BRE EnvironmentalAssessment Method) allowing VMZINC tocontribute to schemes such as the Code forSustainable Homes.
Since 2009, VMZINC has been OHSAS 18001certified, thus conforming to occupationalhealth and safety management systems.
VMZINC manufacturing plants haveconformed to ISO 14001 since 2004/5 soprocesses are strictly controlled to ensurethat emissions are significantly below thenational regulation threshold.
ISO 9001 is the internationally recognisedstandard for the quality management ofbusinesses and applies to allUmicore/VMZINC products and services.Certification was originally obtained in 1997and updated in November 2003 to conformto ISO 9001: 2000.

The systemsUnderlying principles
6 Facade
Facade
VMZINC has been used as a material to cladfacades for many decades. Initially traditionalroofing systems such as standing seampanels were installed as `roofs on walls`. Flat lock panels have also been installed formany decades. Both of these systems requirevented continuous substrates and arecommonly installed by traditional hard metalroofing contractors. Over the past twodecades rainscreen facades have becomevery popular and VMZINC offers a number ofthese rainscreen systems.
A raincreen facade is an outer skin that isback-ventilated by an air space that is38mm deep. The system can be used onboth new build and renovation but alwaysallows the outer layer to breathe whilst theinner layer deals with thermal insulationand air leakage. All joints are dry and do notuse any form of sealant.
VMZINC wall panels can be joined usingthree mechanical joints:
� Standing seam
� Flat lock
� Reveal
VMZINC PLUS is a unique patented productthat allows zinc to be installed on ventilatedplywood (page 10).
The product consists of VMZINC (in allfinishes) having a 60μm coating applied tothe underside thus allowing a more variedamount of substrates to be used andeliminating the risk of the formation ofwhite rust on the underside of the zincstanding seam panels. VMZINC PLUS resiststo an abrasion of 40 litres when tested inaccordance with ASTM D 968.
VMZINC offers a standardised range offlashings that can be used on the majorityof VMZINC facade systems thus makinginstallation more efficient.

VMZINC wall panels will offer very differentaspects depending on the type of panelused. Whilst standing seam panels can offera continuity from roof to wall they will notoffer absolute flatness. Flat lock panels alsooffer a more textured finish. The interlockingpanel system provides flat panels but theyare limited to 300mm in width. VMZcomposite material on the other hand canoffer excellent flatness whilst maintainingpanels of up to 1100mm wide.

Standing seam
Overview VMZ Standing Seam is a ventilated cladding system that can beused for both renovation and new build. As the name standingseam implies, the system consists of seams that can be crimpedin a single or double lock (for greater flatness single lock seamssometimes referred to as angle seams are recommended). Thesystem has a traditional look with the seams being 25mm high.The trays can be installed horizontally, vertically and at an angle.
This facade system offers the possibility to clad all types of walls:flat, curved or complex forms. Another great advantage of thiszinc facade system is that it can be used on both walls and roofs,thus allowing roof and wall to blend as one (standing seam roofsrequire double lock seams). The cladding panels can be varioussizes but we would not recommend that they be more than 4m inlength and 430mm in width. All aspects of VMZINC can be usedwith 0.8mm being the recommended thickness for facades.

Structure
Installation
Fixed clip
The system is very lightweight as the panels weigh no more than7kg/m2 and can be fixed back to both soft wood open gapboarding and plywood. Both substrates require the use of 18mmthick wood and a vented airspace should be left behind thetimber of at least 38mm. The plywood must be weather and boilproof. WBP plywood is more precisely described as EN314-3 (gluebond) and EN636-2 (timber performance).When soft wood opengap boarding is used it is possible to omit every other board,however a fully boarded substrate should be used in accessibleareas. The substrate must be flush to within 2mm and all screwsand nails must be countersunk. VMZINC PLUS must be used onplywood substrates.
The panels are installed in a sequential order from either left toright or right to left for vertical panels. Horizontal panels must beinstalled from bottom up. For panels less than 2m in length fixedclips can be used. For longer panels sliding clips must be usedtowards the bottom on vertical panels and to the left and right ofthe centre for horizontal panels. VMZINC clips are made from 304stainless steel and each clip must resist a pull-out force of 50daN.It is recommended that screws be used to secure the clips withthree being used per sliding clip. The use of nails offers significantly less resistance, but in the event of using nails,contractors are advised to use ring shank nails.
The panels should be installed with the protective film in place.

Overview VMZ Flat Lock panels, sometimes known as shingles, are installedon a continuous vented substrate on both renovation projects andnew build alike. The system consists of panels with 180 degreehems approximately 25mm wide that interlock and are held on thesubstrate using cleats. The system allows a great deal of flexibilityas flat lock panels can be made to many shapes and sizes. Thepanels can be square, diamond shaped and rectangular. Themaximum recommended visible width for a panel is 600mm withthe maximum length being 3000mm. The thickness of the zincused will depend on panel dimensions with small panels using0.7mm zinc whereas the larger panels will require 1mm thick zinc.Increased zinc thickness will offer a flatter panel, howeverincreasing panel dimensions will have the opposite effect and mayinduce some unevenness.

The system is very lightweight as the panels weigh no more than8kg/m2 and can be fixed back to both soft wood open gap boardingand plywood. Both substrates require the use of continuous 18mmthick wood and a vented airspace should be left behind the timber ofat least 38mm. VMZINC PLUS must be used on plywood substrates.
The panels are installed in a sequential order from bottom up. Thepanels are held in place using cleats which can be stainless steel, zincor galvanised steel. For larger panels galvanised steel cleats arerecommended. The cleats should be fixed at a maximum of 330mmcentres. For small diamond shaped panels the hems should be slightlynotched thus allowing the cleat to sit securely. When installing largerectangular panels the short side should be fixed with a long fixingstrip. It is recommended that screws be used to secure the cleats. Theuse of nails offers significantly less resistance, but in the event ofusing nails, contractors are advised to use ring shank nails. The panelsshould be installed with the protective film in place.

Aluminiumrails are 2mm thick with both timber and aluminium railsrequiring a supporting face of at least 40mm. All panels that areover 2m in length must allow for thermal expansion andcontraction by using stainless steel clips. The fixed point being atthe top of the panel for vertical installation and in the middle forhorizontal installation.
The panels are installed in a sequential order from top to bottomfor horizontal panels. The upper edge of each panel is engagedinto the lower edge of the panel above. The panels are mechanically attached using screws and/or the panel fixing clipthat allows for thermal movement. The panels should be installedwith the protective film in place.
VMZINC PLUS must be used on all non-vertical flashings if opengap soft boards are not being used.

VMZ Sine Wave is a corrugated profile inzinc that can be fixed to a wooden or ametal framework. Along with face fixedVMZ Composite sheets this is one of thefew VMZ facade systems that relies onvisible fasteners. The standard profile forthe panel is an 18/76mm module which isavailable in both 0.8mm and 1mmthicknesses. The system can be used toclad walls both horizontally and vertically.

The system is fixed back to timber or metal (galvanised steel atleast 1.5mm thick or aluminium at least 2mm thick) rails that aretypically at centres of between 0.8m and 1.2m (depending onloading). The rails must have a supporting face width of 40mmand should allow a minimum vented space between the VMZ Sinewave panel and the insulation/sheathing of 38mm.
The panels are installed in a sequential order from bottom up.Panels are fixed in place with stainless steel screws on everyother wave. The maximum length for the panels is 6m. For panelsover 3m in length slotted or over-size holes must be pre-drilled toallow the thermal expansion and contraction of the panels to take place.
The panels should be installed with the protective film in place.

Overview VMZ Composite material consists of two layers of 0.5mm thickpre-weathered zinc and a fire rated 3mm polyethylene core. The material is available in QUARTZ-ZINC, ANTHRA-ZINC and the 4 PIGMENTO colours. The stiffness of VMZ Composite allows verylarge and exceptionally flat panels to be manufactured andinstalled. However the nature of composite material also allows itto be folded into complex and yet rigid shapes. Standard panelscan be up to 3900mm x 900mm in size, however it is possible toextend this to 5900mm and 1100mm. It should be noted that1100mm wide panels are only available in QUARTZ-ZINC.
VMZ Composite is always installed using the rainscreen principalwith a vented air space of at least 38mm between the back of thepanels and the insulation or solid structure. Panels can be installedboth horizontally as well as vertically. The panels can also be fixedwith visible fasteners or using a cassette system with hidden fixings.VMZINC Composite can also be fixed using a structural bond (verticalpanels only) thus providing another secret fix option.

The system is lightweight as the panels weigh no more than13kg/m2 and are generally fixed to aluminium cladding rails witha thickness of at least 2mm. The zone behind the panels must bevented and at least 38mm deep.
The panels are installed on cladding rails. The exact dimensioningof the rails and brackets will depend on loadings and panelorientation. Vertical panels are generally installed using a hookand pin principal whereas horizontal panels rely on a continuousrail. Depending on the system used, individual panels may beindependently removable. Standard panel installation is bottomup with the standard joint width being 20mm.
The panels should be installed with the protective film in place.
VMZINC PLUS must be used on all non-vertical flashings if opengap soft boards are not being used.

Overview A number of other zinc rainscreen panelsystems exist ranging from foldedcassettes in 1mm or 1.5mm thick zinc topanels with aluminium honeycomb backingas well as bespoke perforated panels.These panels have various dimensions butall follow the rainscreen principal of nonsealed joints, being fixed to cladding railswith a 38mm vented air space behind.Although other joint sizes are possible15mm or 20mm reveals are the mostcommon sizes. Timber battens can be usedto support the panels but metal rails aremore commonly used (2mm aluminium or1.5mm galvanised steel). Centre to centrespacing of the rails will vary depending ontype and size of the panels being installed.

Zinc aesthetics Zinc is a material that requires almost no maintenance as the rinsingeffect of rainwater performs this task naturally. However when zinc isused on a non rinsed surface such as a protected facade or soffit it ispossible that the zinc may exhibit some superficial stains. Thesestains will not affect the integrity of the zinc itself. It is for this reasonthat the very dark grey ANTHRA-ZINC should be carefully consideredbefore being designed on a non rinsed facade or soffit. In marinelocations the risk of superficial staining in these areas increases.Whilst stains are possible on QUARTZ-ZINC and the PIGMENTO rangethe visual effect is greatly reduced and therefore these finishes maybe more appropriate for some specific locations.
Zinc can be installed adjacent to limestone. The run off fromlimestone onto zinc material is acceptable. However, limestone dustand gypsum dust generated during cutting operations can react withzinc in the presence of water and form a superficial layer of whiterust. No dust should be in contact with unprotected zinc. To preventwhite rust, good construction practices should be used to limit theamount of dust that comes in contact with the zinc.
VMZINC manufacturing uses a colour management system basedon the Y-Factor. The Y-factor ranges from 0 to 100: 0 is black and100 is white. The range for ANTHRA-ZINC is 5 to 7 and the rangefor QUARTZ-ZINC is 22 to 25. Variations are possible within thisrange when different production batches are used.
All VMZINC facade systems are supplied with a protective film. Werecommend that the film be left on the panels during installation.The film should only be removed when other trades are no longerworking in the vicinity of the completed zinc facade. The filmmust not be partially removed as this will lead to unsightly stains.Panels adjacent to one another must not be left with one filmedand the other unfilmed. The zinc facade panels should bedelivered to site with the film completely covering panel faces butnot so as to obstruct film removal in joints. The protective film canleft on the panels for up to 2 months after panel installation.
VMZINC Membrane is a breather layer that allows water vapour topass through it but is water proof to liquid water (up to a columnof 2m). VMZINC Membrane should be used to protect the internalleaf of the rainscreen wall which is often the insulation.
Whilst zinc has a fire performance rating ‘AA’ - BS 476: Part 3 (`lowvulnerability` class in Scotland) when used on a vented wall it may benecessary to address fire risks created by the vented cavity. This canbe dealt with by creating flashings that compartmentalise the ventedcavity or by using intumescent fire barriers that maintain theventilated cavity in normal conditions, leaving the 38mm continuousfree air space, but, in the event of fire, the intumescent ventilated firebarriers quickly expand to seal off the cavity to prevent fire spread.Not all fire retardant materials are compatible with zinc, thereforeplease contact us should you require project-specific information.
