BGC Plasterboard Installation Tips

BGC Plasterboard is purpose designed as a complete plasterboard wall and lining system, which complies with the requirements of the Building Code of Australia (BCA).

BGC Plasterboard has been tested by the CSIRO (Manufacturing & Infrastructure Technology) in accordance with AS 2588 – 1998: Gypsum Plasterboard;

BGC Plasterboard interior lining provides a blemish free, monolithic, smooth surface ready for decorative paint and thin cover finishes for homes, offices and institutional buildings.

BGC Plasterboard is to be installed as detailed in AS 2589:2007 ‘Gypsum Linings – Application and Finishes’.

Support framing must conform to the BCA and Australian Standards, be plumb, true and level.

BGC Plasterboard may be fixed to timber or CFS (Cold-Formed Steel) light-steel framing or masonry, using plasterboard screws, nails and or adhesive.

Only screws or nails must be used for tiled areas and over existing lining or vapour barriers.

Jointing is effected with Plaster Cement Jointing Compounds and paper tape, to give reinforced crack resistant and seamless surfaces.

Plasterboard Finish Selection

Selecting the level of finish of the interior lining depends on the function of the space, lighting and the desired decorative surfaces required.

For most applications, Finish Levels 4 or 5 are used.

Level 3 is used, where heavy to medium texture finishes are applied and the lighting is non-critical.

Level 4 is most commonly used in commercial and residential work, where the finishes are satin, flat or low sheen paint systems and the lighting is non-critical.

For large area walls and ceilings, where critical and severe glancing lighting have an effect, a Level 5 finish must be used to minimize any adverse effects of harsh lighting.

Early Fire Hazard Indices

BGC Plasterboard has been tested by the NATA accredited
AWTA for fire resistance in accordance with AS 1530.3;

  • Ignitability Index – 13
  • Spread of Flame Index – 0

BGC Plasterboard Framing

BGC Plasterboard may be fixed to timber, CFS light steel framing or furring channels, which satisfy the BCA requirements and which have been plumbed true and straight.

Timber framing must comply with the requirement of AS1684 ‘National Timber Framing Code’ and AS1720.1&.2 ‘Timber Structures’ and have a moisture content less than 16% at time of lining.

CFS light-steel framing must be in accordance with AS/NZS4600 ‘Cold-Formed Steel Structure Code’, AS3623 ‘Domestic Metal Framing’ and AS1397.
BGC Plasterboard may be fixed to CFS steel framing not exceeding 1.25mm BMT. Framing members must have a 35mm minimum face width for nail fixing and 32mm for screw fixing.

Frames must be plumbed true and straight, to comply with the degree of finish required of the BGC Plasterboard.
The tolerance deviation over 1.8m spans, along and across members, for 90% of the wall and ceiling framing.

Steel Frame Application

BGC Plasterboard may be fixed to the framing with either adhesive and nails or adhesive and screws as appropriate.
Water-based acrylic gypsum plaster adhesives such as BGC Stud Adhesive, which comply with AS2753, are suitable for fixing BGC Plasterboard to both metal and timber framing.
Adhesive fixing is used in conjunction with fasteners, except for wet and tiled areas, fire-rated construction, over vapour-barriers or existing work, where mechanical fasteners, nails or screws only must be used.
The position of daubs of BGC Stud Adhesive ‘O’ and permanent fasteners ‘X’ should be as set out.

About CSR Hebel

CSR Hebel is 100% owned by CSR Building Products Limited, one of Australia’s leading building products companies. CSR Hebel manufactures and markets a range of lightweight Autoclaved Aerated Concrete (AAC) blocks, reinforced panels, cladding and lintels for use in the housing and commercial construction industry. CSR Hebel also sells complimentary mortars, tools and accessories.In 1989, CSR became involved with Hebel and established the Australian operation. Since then, Hebel has won wide acceptance as an innovative and environmentally friendly building material due to its speed of construction, excellent thermal/fire/acoustic properties and its design versatility.

Design Overview

As environmental consciousness and social responsibility increases, Hebel is striving to exceed these ideals and set new standards in building materials and residential living.

Designed for inner comfort

With Hebel wall and floor solutions, clients can enjoy a comfortable interior in their home, and be comfortable with their choice for the environment. Manufacture of Hebel materials uses a small fraction of the energy and natural resources used in manufacturing conventional masonry, producing almost no waste or by-products. The highly efficient insulating properties of Hebel also save power in heating or cooling the home.

Designed for inner peace

Hebel wall and floor solutions help you create a tranquil inner space.  We have worked closely with acoustic experts and testing authorities to engineer inherently superior acoustics from our wall and floor systems. They create a sound barrier to external noise and from other rooms within the home.

Designed for peace of mind

Although it’s remarkably lightweight, Hebel is solid and durable. Hebel panels are reinforced with steel for extra strength. Hebel is also extremely fire-resistant and is not a food source for termites.

Designed to save

As they’re lightweight and modular, Hebel materials are quick to assemble, saving building time and costs. They also minimise the need for supporting materials, saving budget resources and energy compared to a suspended concrete slab.

Use Hebel for Better Framed Construction

  • Hebel is a lightweight material, which reduces the structural load on the home, and its requirements for supporting building materials.
  • Their low weight makes Hebel panels ideal for use in difficult applications such as sloping sites.
  • A floor of Hebel panels is steel reinforced, solid and secure.
  • Hebel Power Floor has better thermal efficiency than suspended timber or concrete floors, resulting in reduced heating and cooling costs.  Hebel’s cellular structure allows you to use framed construction and still have excellent insulation and thermal mass.
  • Hebel Power Floor has a fire rating of at least three hours from above and up to two hours from below with an appropriate Gyprock ceiling system.
  • Hebel panels and floors provide better acoustic insulation than many other materials.

  • A standard 2400mm Hebel Power Panel weighs about 74kg when delivered*, which two people can position. No cranes are required.

Space

  • Hebel Power Wall gives you great freedom in designing your home and you can customise the style by applying coloured and textured coatings to the Power Panels.
  • A thinner external wall results in greater internal living space and design flexibility.  A 50mm reduction in external wall thickness can provide about 2% extra internal space for the same external dimensions.

Solidity

  • Hebel Power Wall is a solid choice. It’s extremely strong, and each Hebel Power Panel is steel reinforced.
  • Capable of up to four hours fire resistance for a fire source on the Power Panel side.
  • Hebel Power Panel does not provide a food source for vermin or termites.

Lower Energy Costs

  • As with all Hebel products, Hebel Power Panel has excellent thermal properties. This feature results in lower heating and cooling costs at no additional building expenses.

Hebel PowerWall Fire Resistance Performance

Hebel Power Wall can be subjected to a fire loading as the result of either an external fire source, or an internal fire source. When the wall requires a fire resistance level (FRL) rating, CSR Hebel provides the following guidance.

External Fire Source

For an external fire source, the excellent fire resistance qualities of the Hebel Power Panel cladding protects the structural support framing, and provides a high fire resistance level for Hebel Power Wall.

NOTE

The FRL rating of the wall can be affected by the penetrations and the method adopted to protect these penetrations. A fire collar with a –/120/120 FRL rating will govern the FRL of the wall, even if the wall configuration has a FRL rating of –/180/180. Where required, the performance of the external coating when subjected to a fire loading shall meet the appropriate performance requirements outlined in the BCA. Joints & gaps need to be appropriately fire rated. Eg. vertical control joint will need fire rated sealant & horizontal joints must be blocked with compressible fire rated material.

Fire Certificates & Reports

Copies of the test reports and/or opinions can be obtained by contacting CSR Hebel. A certificate of test FSV 0356 is provided in Appendix D of this guide. Hebel Power Wall achieves a FRL of 240/180/180.

Internal Fire Source

For an internal fire source the studs must be protected by the internal wall linings. Refer to CSR Gyp rock Red Book for specifications.

External Walls in Fire – BCA Provisions

Where necessary, the designer and builder should ensure the structural support framing, its connections as well as the Hebel Power Panel installation are satisfactory when subjected to fire conditions. The BCA Vol 2 (Part 3.7.1) outlines provisions for external walls for fire resistance in a residential building where the external wall is less than 900mm from an allotment boundary or 1.8m from another building on the same allotment. If this occurs an FRL of not less than 60/60/60 is required from the outside.

Fire Performance of Hebel Power Wall

Hebel Power Wall was tested at the CSIRO, North Ryde and a Fire Resistance Level (FRL) of 240/180/180 was achieved (refer to Appendix D). Note, the fire source was on the Power Panel side.  This excellent result enables Hebel Power Wall to be used in the following applications:

  • Walls on zero line allotment blocks.
  • Multi-storey residential dwellings - external walls.
  • Commercial developments.
  • Infill Power Panels.

NOTE

In the above applications, each Power Panel should be screwed as specified in this guide, except a minimum of three screws should be installed through the middle top hat into each Power Panel (refer to the fire test certificate in Appendix D).

Bush fire Areas

BCA 2006 Vol. 2 Part 3.7.4 describes the provisions applicable to construction in bush fire prone areas. The reference code is AS3959. Hebel Power Panel is non-combustible and suitable for all bush fire exposure levels  (refer to Appendix A.6).

Design Considerations

Fire Stop Penetrations

Penetrations through Hebel Power Panel to accommodate pipework, electrical cabling or duct work will have to be protected (fire stop), to prevent the spread of fire through the penetration. The penetration can be protected with proprietary products, such as:

  • Fire rated sealants.
  • Fire collars and in tumescent wraps.
  • Fire rated mortars.
  • Fire rated pillows.
  • Fire rated switch boxes.

CSR Hebel recommends contacting the manufacturer to obtain the appropriate product/solution and installation method for the application and wall configuration

CSR Hebel PartyWall

Hebel™ Low Rise Multi-Residential Party Walls have been developed to provide an effective fire barrier and to satisfy the ever-growing demand for noise abatement in multi-residential framed dwellings. The systems provide cost effective, slender wall sections, with acoustic and fire performance conforming to and exceeding the BCA requirements. Hebel™ PartyWall systems can achieve Rw + Ctr ratings of 50dB or better.

These PartyWall systems consist of specific combinations of Hebel™PowerPanel™, CSR™ Bradford insulation and CSR™ Gyprock plasterboard or CSR™ Cemintel fibre cement sheet. These are used to create a symmetrical wall system, which have minimal components and are relatively compact. The resulting walls exhibit high acoustic insulation and fire resistance performance, which have been proven through registered test facilities.

The primary component of the wall is the Hebel™ PowerPanel™, which is a 75mm thick, steel reinforced panel, manufactured from CSR™ Hebel™ AAC. The AAC in CSR™ Hebel™ products is manufactured from sand, lime and cement, to which a gas-forming agent is added. The liberated gas expands the mixture, forming extremely small, finely dispersed air pockets, resulting in lightweight aerated concrete.As with other CSR™ Hebel™ products, Hebel™ PowerPanel™ exhibits excellent thermal and fire resistance properties. Hebel™ PowerPanel™ is lightweight and easily handled, typically by only two people.

The many benefits of using Hebel™ PartyWall in low rise multi-residential construction include:

  • Acoustic Performance: Significantly reduced sound transmission between units and rooms.
  • Good Impact Noise Resistance: 75mm Hebel™ Intertenancy 001 has discontinuous construction and can be selected to reduce the transfer of impact noise.
  • Fire Protection: Tested systems have very good fire rating properties.
  • Lightweight: Lighter loads on structures compared to masonry block, for equivalent Rw + Ctr rating.
  • Slender Walls: Wall thicknesses range from 275 to 325mm.
  • Cost Effective: Cost savings compared to traditional masonry construction.
  • No Wet Trades: Less mess and a cleaner, safer work area.
  • Less Wastage: Greatly reduced waste, as panels are available in a range of standard lengths. This allows for bestsuited panel length selection, which eliminates or reduces off-cut waste.
  • Speed of Construction: Fast installation and assembly speeds with smaller construction crew requirements.
  • Security: Steel reinforced AAC panels provide a high degree of security between units.
  • Thermal Resistance: Excellent thermal resistance.
  • Technical Support: Competent technical staff can assist with systems information.
