APPLICATIONS

Duracom Facade System, utilizing BGC Fibre Cement Compressed panels and Peer Industries; Cold Formed Section (CFS) steel support framing, to form a strong and durable facade cladding system. BGC Duracom panels fixed to the Peer Industries CFS steel support framing, are ideally suited for versatile architectural facades and parapet applications in industrial, institutional, commercial and multi-storey residential buildings. Duracom panels are designed for installation in a variety of patterns, including vertical, horizontal, brick-bond or diamond inclined. BGC Duracom panels are available in 9 mm and 12 mm thicknesses and may be finished with site applied acrylic paint systems or factory applied high quality polyurethane plain, metallic and special finishes.

 ADVANTAGES

  • Lightweight cladding system.
  • Readily accepts many forms of decorative finish.
  • Highly durable product.
  • Dynamic architectural style.
  • Fully sealed and balanced panels.

ENERGY EFFICIENCY CONSIDERATIONS

Energy efficiency requirements have been introduced into the Building Code of Australia (BCA) for both commercial and residential buildings.Thermal heat transfer into and out of the building envelope will effect the running cost of the building and careful consideration of thermal heat transfer needs to be addressed by the architects, engineers and building designers.Thermal bridging through steel framing will diminish the total R-Value; thermal conductance, of the wall. Thermal breaks are required for steel framed buildings and should be installed between the Peer top hat sections and the Duracom cladding. Thermal break tapes should have a minimum R-Value of 0.2.

PRODUCT INFORMATION 

BGC Duracom panels are a compressed, autoclaved, cellulose fibre reinforced silica/cement panel, specially formulated and prepared to meet the requirements for use in external applications.

Duracom panels have a smooth flat surface and a neat square edged finish, for enhanced expressed joint facades.

HANDLING AND STORAGE

BGC Compressed fibre cement sheeting must be stacked flat, up off the ground and supported on equally spaced (max 400mm) level gluts.

Sheeting must be kept dry. When stored outdoors it must be protected from the weather.

Care should be taken to avoid damage to the ends, edges and surfaces.

Sheets must be dry prior to fixing, jointing or finishing.

COASTAL AREAS

The durability of galvanised nails and screws used for external cladding in coastal or similar corrosive environments can be as low as 10 years.

For this reason BGC recommend the use of stainless steel fasteners within 1km of the coast or other large expanses of salt water.

  • Fasteners must comply with AS 3566, with a minimum Class 3 coating.
  • All screw holes must be filled with an expoxy sealer such as Megapoxy PIHilti  A125 or Hilti CA273, and sand flush to provide a flat surface for the finish coating.

DESIGN CONSIDERATIONS

It is recommended that project specific facade designs be undertaken by a consultant experienced in such detailing.

The design engineer should determine the wind pressure for the project and specify the layout, spacing and fixing of the top hats to the structure.

The deflection of the supporting structure should be limited span/250 for Serviceability Wind Load, or as limited by AS/NZS1170.

In areas where there is a probability of wind loading, care should be taken in the design detailing, especially around all openings, corners and other junctions, to ensure the weather resistance of the total system.

Before the Duracom panels and the supporting substructure is installed and fixed, particular care should be taken that all flashing and waterproofing work is complete, including all vapour permeable building wraps and damp proof coursing.

CONTROL JOINTS

In many cases, control joints will not be required as typical expressed joints permit some differential movement of the Duracom panels and the sub-framing.

It is recommended that the designer consider the need for control joints in the following cases:

  • Where the facade crosses a building control joint.
  • Where there is likelihood of movement in the sub-framing.
  • Continuous facades greater than 8 metres in length.
  • At a change in the structural substrate; eg masonry to steel framing.
  • Refer to P16-17, drawings 12, 13 & 14.

PANEL PREPARATION

For insitu paint finish applications, Duragrid panels are supplied sealed with a proprietary sealer applied during manufacture for durability.

Where it is necessary to cut sheets, cutting tools should have a dust extraction system.

Cut edges must be sealed with BGC Edge Sealer or an acrylic coating to eliminate moisture absorption.

A saw blade such as BGC Durablade with a poly crystalline diamond tip specifically designed to cut fibre cement sheets is recommended.

Ensure work area is well ventilated and wear an approved dust mask (AS/NZS1715 and AS/NZS1716) and safety glasses (AS/NZS1337).

TOP HAT SPAN / WIND LOAD PRESSURE LOAD

Structural sub-frame spacing must be installed in accordance with Peer Industries specifications. Table 4 provides guidance on the Maximum Span of Top Hat Profile.

Peer Industries Top Hat Facade System design capacities. The design capacities of Peer Facade System are in limit state format and are based on AS/NZS1170.2–2002. Wind Loads.

The Top Hat capacities have been calculated in accordance with AS/NZS4600 – cold formed steel structures.

The deflection of the Top Hats is based on serviceability factor of 0.6 x ultimate wind loads and is limited to Span/250.

The Peer Industries Top Hat section can be used for Cyclonic wind areas – region C & D based on wind pressures. (For further information, refer Peer Industries Top Hat Facade Design Manual).

It is the responsibility of the Project Engineer to specify the connection of top hats to the support structure. Minimum 12g screw on each leg of Top Hat i.e. two 12g screws at each crossing of Top Hat & purlin.

INSTALLATION

Before commencing, ensure that all proceeding trade works, including flashing and waterproofing are complete. This includes all vapour permeable building wraps and damp proof coursing.

Determine panel layout then mark out the centre point of each top hat on the purlins, framing or masonry structure.

MARKING OUT PURLINS
Diagram 1

Position the Top Hats according to predetermined and marked spacings and ensure that they are vertical (check with a spirit level).

Fix the Top Hats to the Purlins using self-drilling hex head wafer screw fasteners ensuring that both legs of the Top Hats are fixed to the structural purlins or framing.

Also, ensure that the Top Hats are mounted vertical using a spirit level to check.

For inclined or diamond patterns, check that the inclined angle of the Top Hats are correct.

The Top Hats must be fixed on both legs to minimise flexing of the Top Hats.

Apply the EPDM Foam Gasket Strip to the primary 120 mm Top Hat. The seal can be applied to the mounted top hat insitu or it can be applied to the Top Hat, before it is fixed to the purlins.

Ensure that the EPDM Foam Gasket Strip is applied to the centre of the purpose designed Primary 120mm Top Hat.

Set out, pre-drill and countersink the holes in the panels to be mounted, as set out in the table hereunder.

Screw holes must be pre-drilled, allowing 1 mm clearance over diameter of screw.

Holes must be drilled using a masonry drill bit.

Do not use an impact drill.

Where screws are to be countersunk, depth must be controlled by gauge to restrict head depth to 3 mm maximum.

Refer to Table 5 for Maximum Spacing of Panel Fasteners.

Fix the bottom row of boards allowing a 15 mm overlap over the EPDM seal. Leave the top row of screws in the board loose to facilitate the insertion of the backing strip to the board.

Use the backing strip to space the vertical joint of successive boards ensuring a uniform 10 mm space between successive boards.

VERTICAL SPACING Diagram 7

Prepare the backing strip for installation by applying an appropriate sealer to the bottom (9 mm) edge of the backing strip or by applying the sealer to the top edge of the panel.

INSTALLATION DETAILS

The architectural intent and details of buildings vary from one designer to the next, and the variety of facade details would be impossible to catalogue.

The detail diagrams following are intended to assist the designer in achieving a high quality weather resistant Duracom Facade.

The designer should not digress from the specification set out in this manual.

PENETRATIONS, OPENINGS, WINDOWS AND DOORS

There are numerous varieties of penetrations, openings, and windows and door treatments available, and each weather proofing detail will be dependent on the material, style and manufacturer’s specifications.

Adequate weather proofing of the opening application must be considered by the building designer, in conjunction with the penetration, window and door manufacturer. The diagrams below are a guide only and the designer should consult with the appropriate manufacturers for the detail design to ensure adequate weather proofing.

CONTROL JOINT DETAILS

Structural movement vertical and horizontal control joints are required to match existing structural control joints and should pass through the facade.

The Duracom system utilises a flat galvanised 0.75 mm BMT steel strip.

This strip bridges the Top Hats on each side of the control joint and is riveted to one side only.

Sealant is applied between the strip and the Duracom panel creating a floating weather resistant seal that allows for joint expansion and contraction.

THERMAL BREAK DETAILS

Thermal breaks are required for steel framed buildings, in walls enclosing habitable and or useable spaces.

Careful consideration of thermal heat transfer and the position of thermal breaks need to be addressed by the architects, engineers and building designers.

Thermal breaks should be installed between the Peer Top Hat sections and the Duracom™ cladding.

Balustrades, parapets, and other non-enclosing wall elements may not require thermal bridging, except where the possibility of high thermal heat transfer exists through the steel CFS sections to the main structural steel element of the building.

 

MOISTURE MANAGEMENT

Designers, specifiers and builders have a duty of care to identify moisture-associated risks with any individual building design.

Wall construction design should consider both the interior and exterior environments of the building to effectively manage moisture. Special consideration should be given to buildings that are in extreme climates or at higher risk of wind driven rain.

In addition, all wall openings, penetrations, junctions, connections, window heads, sills and jambs must incorporate appropriate flashing for waterproofing. All other components, materials and installation methods used to manage moisture in walls should comply with the relevant standards of the Building Code of Australia (BCA).

7.0 Sound Transmission & Insulation

7.1 Overview

The Building Code of Australia (BCA) presents the Performance Requirements for sound insulation ratings. The sound insulation ratings set minimum values to consider two types of sound: airborne sound and impact generated sound. The Performance Requirements for airborne sound insulation and impact sound insulation ratings are dependent upon the form of construction (i.e., walls or floors), Class of Building, and the type of areas being separated. The airborne sound performance requirement is a value that could be the weighted sound reduction index (Rw) or weighted reduction index with spectrum adaptation term (Rw+Ctr). The impact sound performance requirement is a value called the weighted normalised impact sound pressure level with spectrum adaptation term (Ln,w+ Cl). The BCA does provide Performance Requirements for the airborne sound and impact generated sound insulation ratings for a party wall. Refer to Tables 6.1 and 6.2 for sound insulation resistance level of the Hebel PartyWall systems.

7.2 Impact Sound Performance

Impact sound is caused by vibrations, which are transferred directly through the wall and re-radiated as sound in the adjacent room. These sound vibrations can be generated by actions such as closing of a cupboard door.

The transfer of impact sound can be minimised by ensuring no mechanical connection exists between the two sides of the wall. For impact rated walls the new BCA requires walls to be of ‘discontinuous construction’. This refers to a wall maintaining a minimum 20mm cavity between two separate leaves except at the periphery.

Note: For gap widths ≤ 20mm, CSR Hebel has obtained expert opinion that discontinuous construction performance will not be compromised

7.3 Acoustic Performance Design Recommendations

1) CSR Hebel recommends engaging a specialist acoustic consultant on a project-by-project basis to provide design advice, confirmation of anticipated field performance, detailing and installation inspections.

2) When selecting the appropriate Hebel PartyWall, the designer or specifier must be aware that the laboratory Rw values are almost always higher than the field measured values. Therefore, allowances should be made for the lower expected field values during the selection of the system.

3) Separate advice from a specialist acoustic consultant should be sought to determine the effect on acoustic performance due to any changes to the Hebel PartyWall systems, and any required modification of the installation details pertaining to the systems.

4) Increasing of cavity widths, using higher density or thicker insulation or plasterboard, will generally maintain or increase the acoustic performance of the Hebel PartyWall.

5) The acoustic performance values of the Hebel PartyWall systems shown in Tables 6.1 and 6.2 are a guide only as to consistently achievable field performance. They do not constitute a field performance guarantee as factors such as the presence of flanking paths, quality of installation of the system, on-site detailing of junctions, room shapes and size, etc can significantly affect field performance. Maximising the field performance depends on the following factors:

  • The systems are installed in accordance with the manufacturer’s standard installation details.
  • Good quality installation practices including the sealing of all junctions and joints and maintaining specified clearances.
  • The systems are installed with all junctions acoustically sealed so that negligible sound transmission occurs at these points.
  • Flanking paths are eliminated and the structures into which the systems are installed are capable of allowing the nominated rating to be achieved.
  • Site testing conditions.
  • To minimise the transfer of sound through the Hebel PartyWall system into the adjacent unit, it is suggested that a control joint be provided to break the mechanical path for the transmission of impact sound and other vibration.

14.0 Panel Handling

14.1 Manual Handling

CSR Hebel recommends using a trolley or other mechanical apparatus to move the panels around the work site. Manual handling where people physically move a panel, should be kept to a minimum, with the weight being supported by an individual kept as small as possible. Any concerns regarding the weight to be handled should be discussed with the panel installation contractor.

To minimise the possibility of manual handling injuries, CSR Hebel suggests the following:

  • Use mechanical aids, such as trolleys, forklifts, cranes and levers, or team lifting to move panels.
  • Keep the work place clean to reduce the risk of slips, trips and falls, which can cause injury.
  • Plan the sequence of installation to minimise panel movements and avoid awkward lifts.
  • Train employees in good lifting techniques to minimise the risk of injury.

14.2 Health, Safety & Personal Protective Equipment (PPE)

CSR Hebel AAC products are cement-based, which may irritate the skin, resulting in itching and occasionally a red rash. The wearing of gloves and suitable clothing to reduce abrasion and irritation of the skin is recommended when handling CSR Hebel AAC and other concrete products. Approved respirators (AS/NZS1715 and AS/NZ1716) and eye protection (AS1336) should be worn at all times when cutting and chasing. Refer to the appropriate CSR Hebel Material Safety Data Sheet (MSDS).

14.3 Cutting

The use of power tools when cutting concrete products may cause dust, which contains respirable crystalline silica, with the potential to cause bronchitis, silicosis and lung cancer after repeated and prolonged exposure. When using power or hand tools, on CSR Hebel products, wear a P1 or P2 respirator and eye protection. When cutting, routing or chasing CSR Hebel products with power tools, use dust extraction equipment and wear hearing protection. Refer to the appropriate CSR Hebel MSDS.

Reinforcement exposed during cutting is to be coated with a liberal application of CSR Hebel anti-corrosion coating agent.

14.4 Trolley Assisted Handling

CSR Hebel has developed a trolley to allow easier and safer handling of Hebel PowerPanel on-site (refer Image 14.1). There is a range of trolleys to suit panels from 1.2m to 3.9m in length.

Guidelines for handling Hebel PowerPanel using the Hebel PowerPanel Trolley or panel lifters are detailed in Technical Bulletin, CSR Hebel PowerPanel Handling & Installation Guidelines, NºHTB791.
