cking wall. Normally four types of joints are used between the panels. 1. Open joints in which there is a clear open gap between the edges of adjoining panels. 2. Overlap joint in which the bottom of one panel overlaps the top of the lower panel. Shiplap is an example of this. This is only suitable for narrow panels. 3. Covered joints where an expressive feature is used over the joints to highlight the pattern. 4. Baffled joints where a joint profile is positioned behind the panels to block the direct line through the opening, while not sealing it. Consider colour choice of support frame, insulation and backing wall as these may be seen. Joint Size Many years of practice have shown that the optimum width of the joints between large panels is 10mm. A 10mm joint is the best, aesthetically. 10mm also offers the installer a good level of tolerance when installing the panel. Minimum joint – 8mm. Maximum joint - 12mm OPEN JOINTS Arch.: Bo.2 architectuur en stedenbouw

Face Fixings EQUITONE panels can be face fixed using EQUITONE UNI-rivet for metal support frames or the EQUITONE UNI-screw when a timber support frame is used. All fixings are available with colour match heads to blend in with the panel. The rivets and screws are both low profile heads. The fixing systems are designed to accommodate the expansion and contraction of the support frame without putting excessive stresses on the panel. The fixings are positioned at centres to suit the wind load the façade will be subjected to. Normally centres are up to 625mm and will reduce as determined by the wind calculations. The corner position of the fixings should be located within the red box. 100 mm 100 mm 70mm 100 mm 30mm Corner rivet 30 mm 80 mm 100 mm 70mm Refer to Uni rivet and screw fixing guides for full in

formation. 20mm Corner screw 25 mm 80 mm 5.0 Fixings 2. Hidden Fixings For hidden fixings a mechanical system is possible. Please note that this is a precision fixing system and a good knowledge of fabrication and installation is critical to ensure a successful facade. Mechanical Secret Fix The mechanical hanging system utilises an undercut anchor which is secured in the rear of the panel in specially drilled holes. To this a hanger bracket is fixed. This hanger then interlocks with a horizontal rail. * Refer to the individual mechanical hanging systems installation literature for details. This system is suitable for EQUITONE [tectiva], EQUITONE [linea], and 12mm EQUITONE [natura], EQUITONE [natura PRO], EQUITONE [pictura], EQUITONE [textura] and EQUITONE [materia]. 6.0 Support frame EQUITONE panels are strong yet light, which reduces the amount of supporting frame needed compared with other materials. Certification for the structural stability of any supporting frame should be

in accordance with local building regulations and must be obtained by the building’s owner or his representatives namely the project engineer. Common Support Frame Materials Aluminium Galvanised Steel Timber 7.0 Backing wall Structural Wall The backing wall is critical to the performance of a ventilated facade system. If air movement through the backing wall is too great then the risk of water penetration is increased. Air leakage through the backing wall also presents a path for energy loss, and so must be limited. Joints in metal support frame must coincide with a panel joint. 8.0 Special applications General While EQUITONE panels are used as a facade cladding, they can also be used in other applications. 1. Perforations Perforations may take the form of round holes, slots, square, rectangular holes or random shaped holes. 2. Extreme cuttings 3. Milled surfaces 4. Curved Walls EQUITONE panels are flat. However it is possible to ease them around a curved facade. Note that t

he orientation of the panel is also critical. A horizontal panel bends easier than one placed vertically. The minimum radius that an 8mm EQUITONE panel can be UNI-rivet or UNI-screw fixed to a curving facade is 12.0m. Please contact your local EQUITONE Service team for more assistance.

Roof applications EQUITONE [textura] and [pictura] can be considered for applications on a roof. Please bear in mind that the panel is only decorative and there must be a suitably designed water-proof construction under the panels. Please contact your local EQUITONE Service team for more assistance. 6. Weatherboard / Shiplap Pattern An alternative to the flat facade is the shiplap appearance which emphasises the horizontal lines. This consists of narrow panels fixed to the facad

Brise soleil and shutters EQUITONE can be used as a Brise Soleil, shutter or architectural feature of a building. To be installed both horizontally and vertically.The Brise Soliel or shutter gives the feature of a continuous façade and can also be perforated if required to give a unique visual aspect to the façade. Not all materials are suitable for this application, please contact your local technical support for additional information. 8. Curtain Walling The post-and-beam or stick system is normally assembled on site. The vertical members are fixed to the floor slab and then connected with horizontal transoms. Into this frame will fit the glazing or panels. 9. Internal Use The use of EQUITONE panels internally is possible, please contact your EQUITONE service team for more assistance. ROOF APPLIC

Principles: Protect the top of the cavity against water ingress. Ensure sufficient air flow is maintained out under the coping. For wider gaps a perforated profile can be used to prevent entry of birds. Where a parapet is desired without an overhanging coping it is important to; For EQUITONE [materia] the following capping dimensions should be followed. A minimal 20mm (50mm in case of copper) should be left between the front of the panel and rear of the capping. The front edge of the capping must offer adequate cover to the panels and provide a minimum of 50mm by buildings up to 8m and a minimum of 80mm by buildings up to 20m and a minimum of 100mm by buildings over 20m protection.

als can be used for a soffit application either as a small soffit and fascia or a large soffit/ceiling. When used in this application it is recommended to ventilate the rear of the material and to reduce the framing/fixing centres. Please contact your local EQUITONE Service team for more assistance. A clear ventilation path must be provided at the head of any façade panel/framing where it abuts a soffit. Depending upon the soffit type and finish this may require ventilation as well.

Then, unnecessary and high costs are avoided in the long term. The building also retains its continuous and attractive appearance. If one the allows the soiling to work into the materials for too long, it is possible that it will have penetrated so deeply into the pores of the material that simple cleaning is no longer possible The building should be designed with access in mind so all panel areas can be inspected and maintained. There are two methods of cleaning façades, mechanical cleaning and chemical cleaning. In principle, p

erform the cleaning of the facade over the entire surface, because partial cleaning can result in colour tone differences. Normal stains can be removed with a sponge and water. The use of abrasive materials such as scourer, steel wool, etc. is not allowed, as they leave irreparable scratches on the surface. THE SOILING PROCESS AND METAL FLASHINGS Dust, soot, oils, greasy substances, etc. are present in the air and rainwater and can be deposited on a façade. If care is taken through considerate design and application, local soiling and runs can be avoided. This can be achieved by having adequate drip-moulding, good sealing and attention to combat corrodible materials such as zinc, copper, aluminium, steel, etc. The degree and speed at which materials become soiled largely depends on the surface, chemical stability, hardness, porosity, ability to become electrostatically charged or not. Consideration should be given to how the building may weather and the how the water run-off from mat

erials affects other materials below. GRAFFITI The UV-cured EQUITONE [pictura] and EQUITONE [natura pro] surface coating provides superior protection against common colours and spray paints. It is smooth and cleanable. The [pictura] and [natura pro] surface coating meets the requirements of the placement test and test cycle 2 of the Quality Association for Anti-Graffiti eV for surface-protective anti-graffiti systems (ILF 4-013/2006 report of the Institute for paints and inks eV). Note that when an on-site graffiti protection is applied to the panels the appearance of the panel may change as the protection effects the light reflectance of the panel’s colour. EFFLORESENCE Lime scumming can be avoided by handling the sheets in the correct way. The sheets must be stacked in a dry ventilated space. The sheets must always be protected from rain. During storage the synthetic film may not be removed; the foil is only removed with use. If the sheets do become wet in the packing, all packag
