CSR Hebel Introduction

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) products. The current product range includes blocks, reinforced panels, cladding panels and lintels for use in the residential 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 CSR Hebel has manufactured products that have won wide acceptance as innovative and environmentally friendly building materials. This is due to their lightweight yet solid nature, excellent thermal, fire and acoustic properties and design versatility. The inherent properties of CSR Hebel products help achieve quick and cost efficient construction practices as well as providing for comfortable operating environments inside the buildings all year round.

Design Overview

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

With CSR Hebel wall and floor solutions, clients can enjoy a comfortable interior in their home, and be comfortable with the choice for the environment. Manufacture of CSR Hebel materials uses a fraction of the energy and natural resources used in manufacturing conventional Designed for inner peace masonry, producing almost no waste or by-products. And CSR Hebel AAC’s highly efficient insulation saves power in heating or cooling the home.

Designed for inner peace

CSR Hebel wall and floor solutions help create a tranquil inner space. We have worked closely with acoustic experts and testing authorities to engineer inherently superior acoustics.

Designed for peace of mind

Although it’s remarkably lightweight, CSR Hebel AAC is solid and durable. CSR Hebel panels are reinforced with steel for extra strength. CSR  Hebel is also extremely fire-resistant and is not a food source for termites from our wall and floor systems. They create a sound barrier to external noise and from other rooms within the home.

Designed to save

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

Use CSR Hebel for Better Sound Insulation

With advances in technology (particularly the home theater system) and consumer’s demand for home listening pleasure the need for wall and floor systems offering excellent sound insulation has developed.

Recognising the unique properties of AAC, CSR Hebel was one of the first building products manufacturers to respond to this growing need by developing a range of acoustic wall systems. Since then the peace and amenity of thousands of multiunit households and commercial developments have benefited from Hebel PartyWall.

As of the 1st May 2004 the Australian Building Codes Board (ABCB) announced that the minimum Building Code of Australia (BCA) sound insulation requirements have been increased. CSR Hebel’s acoustic performance will help you reach the new standard, while also benefiting from the unique lightweight yet solid feel of CSR Hebel products.

Hebel Low Rise Multi-Residential Party Walls

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.

CSR Hebel Regulatory Issues and Selecting a Hebel Party Wall

Dwellings Constructed Side-By-Side on a Single Allotment

Where it is proposed to construct single dwellings side-by-side on a single allotment the internal wall between dwellings is a fire separating wall as defined in the BCA. The fire separating wall must start from the ground level (top of concrete footings or top of floor slab) and achieve a 60/60/60 FRL if load bearing, or –/60/60 FRL if nonload bearing. The wall must go to the underside of a non-combustible roof covering and any gaps be filled with fireresisting material as described in Detail 3.7.1.11 of Volume Two of the BCA.

Dwellings Constructed Side-By-Side on Separate Allotments

Where it is proposed to construct single dwellings side-by-side on separate allotments, or if subsequent subdivision is proposed, the wall might also be considered an external wall and each dwelling may be required to have its own wall starting from the ground level (top of concrete footings or top of floor slab) and each achieving a 60/60/60 FRL if load bearing, or –/60/60 FRL if non-load bearing. Contact your local authorities, as there may also be applicable legislation or discretionary powers available to vary these provisions.

Dwellings Constructed SideBy-Side on a Single Allotment Where Subdivision May Subsequently Occur

Where it is proposed to construct single dwellings side by side on a single allotment and it is known that subsequent subdivision will occur, or that subdivision might occur (and this will probably apply to most multi-dwelling developments) then, after subdivision, the internal fire separation wall might also be considered an external wall and each dwelling may be required to have its own wall starting from the ground level (top of concrete footings or top of floor slab) and achieving a 60/60/60 FRL if load bearing, or –/60/60 FRL if non-load bearing. Contact your local authorities, as there may also be applicable legislation or discretionary powers available to vary these provisions.

Hebel PartyWall Solutions in tiered applications

Where the internal fire separation wall extends beyond the roof line on one side only and becomes an external wall, contact CSR Hebel Engineering Services for advice on PowerWall external wall solutions.

Compliance with the Building Code of Australia (BCA)

All building solutions, such as walls, floors, ceilings, etc. must comply with the regulations outlined in the Building Code of Australia (BCA) or other authority.

The BCA is a performance based document, and is available in two volumes which align with two groups of ’Class of Building’: Volume 1 – Class 2 to Class 9 Buildings; and Volume 2 – Class 1 & Class 10 Buildings – Housing Provisions. Each volume presents regulatory Performance Requirements for different Building Solutions for various classes of buildings and performance provisions.

These Performance Provisions include:

  • Structure
  • Fire Resistance
  • Damp & Weatherproofing
  • Sound Transmission & Insulation
  • Energy Efficiency

This design guide presents tables and information necessary to design a Hebel PartyWall installation that complies with the Performance Requirements of the BCA. The designer must check the adequacy of the building solution for Performance Requirements outlined by the appropriate authority.

STEP 1: Scan the ‘System Selection’ table for the required characteristics.
STEP 2: Turn to Section 6.0 and select the appropriate Hebel PartyWall solution.
STEP 3: Confirm the selected Hebel PartyWall solution has adequate Fire Resistance Level (FRL) rating and acoustic performance level.
STEP 4: If an appropriate Hebel PartyWall can not be selected, contact CSR Hebel Engineering Services for advice.

CSR Hebel Fire Resistance Performance & Structural Provisions

Fire Resistance Level (FRL) Rating of PartyWall Systems

The fire resistance level (FRL) rating performance of the Hebel PartyWall system detailed in this guide have been derived from Warrington Fire Research assessment WFRA – 45771.3, WFRA – 45772.1 and Warrington Fire Research, fire resistance test report, WFRA – 41154.2.

This design guide has no recommendations for penetrations through the PartyWall system. CSR Hebel recommends contacting the appropriate consultant for design and detailing advice.

System Variations

Certain variations to the Hebel PartyWall installation will not affect the fire-resistance levels listed in Tables 6.1 and 6.2. However these variations need to be approved by the project fire consultant or project certifier. The possible variations to the systems include:
1) Changing the type of insulation between polyester, glasswool and rockwool;
2) Putting the insulation on both sides of the PowerPanel;
3) The reduction of a cavity between the wall frame and the Hebel  PowerPanel/ plaster board down to 10mm for 75mm Hebel Intertenancy 001.

Structural Provisions

Structural Performance

The Hebel PartyWall system can be either a loadbearing or non-loadbearing wall. The Hebel PowerPanel within the wall system is non-loadbearing with the exception of self weight.

Construction Loadings

During construction, the Hebel PowerPanel could be subject to wind loading. The builder shall provide the necessary temporary bracing of the panel until both structural frames are
installed.

Note: The screw connections may not be adequate to stabilise the panel against construction loadings.

Cutting of Hebel PowerPanel

The standard Hebel PowerPanel can be reduced in length by cutting 150mm maximum from each end, and to a minimum width of 270mm. All exposed steel reinforcement shall be liberally coated with the Fentak anti-corrosion coating available through CSR Hebel.

Wall Frame

The wall framing presented in this Design Guide for various wall systems are nominated for the acoustic and fire performance values. It is the designer’s responsibility to determine an  appropriate wall  framing  system to  satisfy  structural  adequacy.  Several  items the designer  must allow for are:

  •  lateral loadings
  •  wall height
  •  deflection limits
  •  offset distance (gap) from the panel
  •  building movement
  •  control joint locations

Wall Height

The overall wall height limit is 12m for both 75mm Hebel Intertenancy 001 and 75mm Hebel Intertenancy 002. The wall shall be constructed of Hebel PowerPanel of 3000mm maximum length. Walls constructed with panel lengths exceeding 3000mm are outside the scope of this guide.

Earthquake Loading

Earthquake loading has not been considered in this design guide. It is the designer’s responsibility to ensure the connection system has adequate capacity to resist any imposed earthquake loading.

Fixings

Fasteners & Fixings
Most screw fixings are timber type, which is sufficient for penetrating the metal thicknesses outlined in this design guide. Connections that have larger metal thicknesses may require a metal type screw and will need to be designed and approved by the project engineer.

Fixings – Deflection head track to substrate
The fixing to secure the angles and tracks to the concrete slab shall be capable of   with  standing  a shear load of 0.75kN. For high wind pressures during construction, the designer shall determine if mechanical fasteners are required:

  • Drive pins and concrete nails (check size and suitability for fire rated situations with the manufacturer);
  • 8mm diameter mechanical fasteners.

Table 9.1 outlines the connection type and requirements for constructing 75mm Hebel Intertenancy 001 and 75mm Hebel Intertenancy 002 detailed in this design guide.

CSR Hebel Installation Guidelines

General

Before commencing any installation work, clean and tidy up the work area. Mark out the location of the walls.

Wall Framing

Ensure frames are installed plumb and mechanically fixed to the substrate.

All timber framework is to be fabricated and installed to the manufacturer’s specifications and AS1684 or AS1720.1.

Services

Ensure all services are installed within the wall frame and not on the face of the Power Panel.

Deflection Head Track

When the wall locations have been set out, fix the deflection head tracks to the substrate. This is done using suitable fixings (see Section 12.0) at 600mm maximum centres and maximum 100mm from ends. At changes in wall directions, ensure deflection head track is mitred with no gaps at the corners. Seal all butt joints with polyurethane sealant.

Hebel Mortar

Mortar is placed on the DPC and should only be run out roughly 3 panels (1800mm) ahead of panel installation. The mortar bed fills the gap at the base. Generally, the mortar is 10mm thick and shall extend the full width of the panel. Mixing of the mortar should be done in  accordance with the instructions on the bag.

Wall Brackets

Screw fix the wall bracket to the top and bottom plates of the wall frame and to the Power Panel at 600  centres. Locate within 50mm of the centre width of each panel using fixings specified in Section 12.10.

Top Hats

Top hats should be cut to size before securing them to timber studs. At control joints the top hats should be discontinuous. For number, location, spacing and fixing of top hats, refer to the project specifications. The project classification (Torrens or Strata) will determine the future external loading parameters of the panels and associated top hat and fixing arrangement required.

Hebel Power Panel 

The panels can be cut on-site using a circular saw equipped with diamond tipped cutting blade (for panel cutting limitations refer to Section 9.0). All the loose AAC particles should be  brushed off  the panel with a  rough broom.  Steel  reinforcement that is exposed during
cutting must be coated with a liberal application of corrosion protection coating (see Section 12.0). Any minor damage and chips to the panels must be repaired using Hebel Patch.

Use packers at  the base to maintain the gap and ensure gap is  full of mortar  (if specified).
The preferred method of fixing should be to screw through the top hat/bracket into the panel. Fix  the panel to the  deflection head  (if specified).  For following panels, apply Hebel
Adhesive to the vertical edge and install the next panel. Repeat the installation process until the wall is complete.

Hebel Adhesive

Hebel Adhesive is applied to the panel with a 75mm Hebel notched trowel. When the panels are pushed together the joints are to be 2-3mm thick. Sufficient pressure must be applied to the panels when gluing to ensure the adhesive is fully bedded across the joint. Scrape off any excess adhesive protruding from the joints and fill any gaps. Adhesive is to be mixed to the proportions and consistency as per the instructions on the bag.

CSR Bradford Insulation

Installation of CSR Bradford insulation should be completed in accordance with  manufacturer’s  handling  and  installation  guidelines.  The insulation  provided   should
completely fill the space between the stud framing and form a continuing barrier. If there is any gap in the insulation the acoustic performance of the system may be adversely affected.

Gyprock Plasterboard

Plasterboard sheets must be cut to fit neatly and should not be forced into position. The plasterboard is to extend the full height of the wall frame, with gaps at top and bottom for the specified sealant.
Plasterboard is fixed directly to the stud framework in accordance with the Gyprock Plasterboard Residential Installation Guide, NºGYP547.

 Sealants

All movement joints and other gaps should be sealed off and finished neatly with fire and acoustic rated sealants. Installation of sealants must be carried out in accordance with the
manufacturer’s specifications.

Installation of Electrical, Plumbing and Other Services

Installation of services into walls should be carried out at an appropriate construction sequence. This will allow easy access to cavities and wall frames, where services can be easily installed and neatly hidden.
CSR Hebel suggests installing the plumbing and cabling after the panels have been installed. The builder or project manager should confirm appropriate construction sequence for services on a project-by-project basis.

Fasteners & Fixings

All fixings and fasteners should be installed in accordance with the manufacturer’s specifications.Find Out More
