NATURA PRO, TEXTURA & PICTURA

Transcription

1 Natura Pro, Textura and Pictura façade systems are architectural cementitious boards installed onto a specifically designed Benchmark. NATURA PRO, TEXTURA & PICTURA FAÇADE DATA Materials The cementitious boards are fibre reinforced cement boards that satisfy the requirements of Category A Class 2 to BS EN (Fibre-cement flat sheets). Panels are manufactured on a hatschek machine, compressed and air cured. The boards are available in a variety of colours with a choice of a smooth, granular or matt finish. A UV cured top layer (excluding Textura) offers good protection against many types of staining, against mechanical damage and against graffiti. Dimensions Typical standard panel sizes are 2500mm x 1250mm, 3100mm x 1250mm Textura can achieve 3100mm x 1500mm. Sizes indicated exclude 10mm joint. Face Panel Thickness : 8mm* or 12mm. *This thickness for visible fixed applications only. Please Note: Dimensions are restricted to 1196mm x 596mm or 1000mm x 1000mm maximum with the alternative secret fix method of vertical straps on rails (please see page 3). All sizes indicated above exclude 10mm joint. Please be advised the sizes stated are maximum sheet sizes available after trimming by a fabricator. Sizes can be tailored to the build option- please contact Benchmark Technical Services for more information.

For Project Specific weights, please contact Benchmark Technical Services Department. Benchmark SF System The cementitious boards will be fixed invisibly by attaching metal hanging brackets with undercut stainless steel expanding anchors.the cementitious boards are then attached to aluminium rails. Each panel has two adjusting points and a fixed point at the top of the panel through the attached brackets. The aluminium rail attached to vertical tophats which are in turn attached to the. Alternative secret fix method Invisible Fixing with Vertical Straps on Rails The cementitious boards will be fixed invisibly by attaching straps to the façade which fix back to a horizontal rail which is attached to the. The extruded aluminium straps (tested to BS 1474 in 6063/T6 grade alloy) are secured to the façade panel using undercut stainless steel expanding anchors. The straps are secured to the aluminium secondary rail system (tested to BS 1474:1987 and powder coated black) using self drilling/ self tapping stainless steel coated black screws. The secondary rail system is then attached to the. *Please see page 1 for information on dimension restrictions when using this attachment method. SYSTEM ATTACHMENT There are three different types of system attachment options which are as follows; Benchmark FF System The cementitious boards will be fixed with rivets to vertical aluminium omegas and/or zeds which are, in turn attached to the Karrier panel system.

5 STRUCTURAL LOAD/SPAN TABLE FOR KARRIER PANEL (To be checked against unfactored design wind-loads) Notes: 1. Values have been calculated using the limit state method in the European Recommendations for the Design of Sandwich Panels (ECCS document No ), taking imposed loads, temperature and creep into account. 2. For each value individual and combined load cases with appropriate load factors and temperatures have been considered. These are detailed under Structural Performance in Building Design Section. 3. The table is for dark coloured panels. 4. The following deflection limits have been used: Pressure Loading L/100 Suction Loading L/ For intermediate values linear interpolation may be used. 6. The actual wind suction load resisted by the panel is dependent upon the number of fasteners used and material of the rail. The fastener calculation should be carried out in accordance with the appropriate standard. For further advice please contact Benchmark Envirocare Technical Services. 7. The allowable tolerance between bearing planes of adjacent supports is L/600, where L is the distance between supports. 8. Load span tables for spans outside of those shown are available from the Benchmark Technical Services department.

6 PACKING AND STORAGE Cementitious Boards The packing and storage of cementitious boards varies slightly dependent upon the attachment method. Cementitious boards should be stored and transported on a flat, dry surface which gives support over the entire area. Stack to a maximum height of 1.0 metre, preferably on pallets, or on dry wooden slats placed sufficiently close to avoid sagging. The panels should be covered, for example with a heavy-duty tarpaulin, to protect against dampness, weather and dirt. The covering must remain in place at all times for stacked material. For visible fix, cementitious boards will be laid flat on pallets which have supports at not more than 600mm centres. The packs will be wrapped in a waterproof membrane. For invisible fix, cementitious boards will have brackets or straps attached (dependent on secret fix option) so will be laid on a pallet face to face and back to back with supports in between at maximum of 600mm centres. The pallets will have supports at not more than 600mm centres. Packs will be wrapped in a water proof membrane. The boards should be stored horizontally on level firm ground with sheets on timber bearers. If the cementitious boards are stored outside, the polythene hood should be removed and the sheets should be covered with a tarpaulin on bearers. This is to allow free air movement. If the panels are allowed to become wet before installation efflorescence could occur. Individual panels should be stored on edge with air circulation on both sides. If only one side of a panel dries out or becomes damp this can lead to deformation. Paper or foil is inserted between front surfaces to protect the high quality finish, and this should be kept in place when restacking. Stack the panel s front face to front face or rear surface to rear surface. The Benchmark s are stacked horizontally. Removable hot melt adhesive is laid between each panel. The top, bottom, sides and ends are protected with polystyrene and timber packing and the entire pack is wrapped in polythene. To ensure panels remain in prime condition while stored onsite, the panels need to be stored in a safe, clean and trade free area. Personnel should not walk over packs. Store the panels on a slight slope ensuring any penetrating rainwater drains off and ensure regular inspection the panel packs. Should panel s need to be stored for a period of time in excess of 3 months, please contact Benchmark Technical Services. The number of panels in each pack depends on panel length and weight. Typical pack height is 1100mm (based on 100mm thick panel). Maximum pack weight 1500kg. For information regarding the number of panels per pack, please contact Benchmark Technical Services. Sea Freight Fully timber crated packs are available on projects requiring delivery by sea freight shipping, at additional cost. Alternatively, steel containers can be used. Special loading charges apply.

7 HANDLING Off loading of heavy loads should be carried out with care, to avoid unnecessary strain on the handler and accidental damage to the product. Mechanical handling equipment to be used if available. Each board should be lifted from the pile by two workers, removed without scraping the other boards and then carried vertically. Natura Pro board should always be carried upright. QUALITY & DURABILITY Benchmark components are manufactured from the highest quality materials to rigorous quality control standards, complying with ISO 9001:2000 standard, ensuring long-term reliability and service life. GUARANTEES & WARRANTIES Benchmark will provide external coating and product guarantees on an individual project basis. DELIVERY AND OFF- LOADING Transportation of Benchmark packs to site is by road transport (unless indicated otherwise). It is the customer s responsibility to check the site for restrictions (i.e. entrance to site, power lines etc.) and agree a storage area to be used, also to identify the correct type/methods of off-loading/hoisting facilities to be used i.e. crane, crane forks, lifting beam/ slings and airbags, forklift or specialist lifting equipment. Always check the current certification of the crane, crane forks, lifting beam, slings, forklift, or specialist lifting equipment prior to carrying out offloading/hoisting operation (i.e. with correct current SWL Certification).
