Hebel® is Australia’s leading manufacturer of autoclaved aerated concrete (AAC), a non-toxic, lightweight masonry which has remarkable properties in one product:

• Non-combustible• Excellent thermal resistance as well as thermal mass• Good acoustic insulation• Quick to install• Lightweight with a solid masonry feel

In Australia, there are two basic methods of building homes. The first and most common is the framed construction method, traditionally used for brick veneer over a timber frame. The second is the solid, or loadbearing construction method, generally used for double brick for block homes. Whichever method you choose for building your home, Hebel® has the systems to suit.

Framed ConstructionFor framed construction, Hebel® PowerWall™ and PowerClad are the ideal building systems that meet energy efficient requirements and deliver a beautiful finish when rendered.

The Hebel® PowerWall™ system uses vertically installed panels that are suited to a supply and installation service. PowerWall is the traditional Hebel panel system that is quick and easy to install.

The Hebel® PowerClad system uses horizontally installed panels designed for your existing trades to install. PowerClad is easy to handle due to the smaller panel size and is easily handled by 1-2 people, making it ideal for upper storeys.

Frameless ConstructionFor solid construction, Hebel® PowerBlock creates loadbearing walls for a frameless home with exceptional performance.

Other systems available from Hebel® include:

• PowerFloor™ - a solid flooring system ideal for first floors and suspended ground floors as well as decks and balconies

• Floor Panels - when combined with Hebel® PowerBlock, you can eliminate the need for timber or steel framing in walls and floors

• PowerFence™ - a versatile fence system that provides an effective noise barrier for residential applications

• Party Walls – internal walls with high acoustic performance.

Designed for future living

Homeowner BenefitsHebel® is marketed under the Hebelhome brand to consumers providing significant benefits.

A Hebelhome is beautiful, comfortable, responsible and now more affordable than ever.

BeautifulHebelhome combines clean architectural lines with a wide choice of contemporary colours and textures to create a stylish, modern character. Hebel® has worked closely with leading coatings manufacturers to develop a range of finishing options from full acrylic systems to high build renders and textures designed specifically to complement the home.

ComfortableThe thermal and acoustic insulation properties of Hebel® can significantly improve the comfort of a new home. Hebel® panels have up to five times the thermal resistance of a standard house brick.

For a quieter living experience in 2 storey homes, installing Hebel® PowerFloor™ can make the living experience more tranquil by noticeably reducing noise between floors. If the home is on a sloping block and there is an exposed ground floor, PowerFloor™ will provide increased thermal insulation compared to alternative flooring materials.

ResponsibleThe low bulk density of Hebel® means that less than a quarter of the resources and raw materials are used in its production than for other masonry products.

Hebel® has been independently assessed by Good Environmental Choice Australia (GECA) as having significantly reduced environmental

loads (more than 60% in many cases) compared with alternative building materials. As a result, Hebel® is proud to have been awarded the GECA Label for each of its products and systems.

To qualify for the GECA endorsement, Hebel® products and systems needed to show significantly reduced environment loads of at least 30% over their life-cycle.

Peace of MindHebel® wont burn and all Hebel® systems meet the stringent standards of the latest Australian Building Standard for extreme bushfire areas.

Hebel® is backed by CSR, one of Australia’s largest and most respected building materials companies. Hebel’s focus on innovative, environmentally responsible building systems has earned it an enviable reputation with architects, builders and homeowners.

Hebel technical support staff can assist with your project design and provide additional system information.

Hebel® systems are an excellent choice for renovations and additions. Rejuvenating a home can cost a fraction of that for demolition and rebuilding. The modern look of a beautifully rendered home can also add substantial value to the property.

Hebel® PowerWall™ and Hebel® PowerClad replace the current cladding - generally weatherboard or cement sheeting with Hebel® sill blocks included under windows.

Hebel® PowerFloor™ provides a solid alternative for suspended external decks and patios and is quick and easy to install.

PowerFloor™ panels are affixed to timber or steel framework on piers to provide a solid, flat surface which can be tiled or simply finished with an appropriate paving paint system.

If stairs are required, Hebel® PowerBlock is an ideal choice. Exposed horizontal surfaces must be fully waterproofed with an appropriate waterproof tanking membrane before applying finishes or tiles.

Refer to the system design & installation guides for detailed fire performance ratings and certificates.

AcousticsSound Insulation Rating of Party Walls

Sound insulation is an important consideration in residential dwellings for the comfort of occupants and Section F5.2 in Volume 1 of the BCA calls for an Rw + Ctr (airborne) rating of not less than 50, if it separates sole-occupancy units.

Sound Insulation Rating of Floors

A floor in a class 3 building must have an Rw + Ctr (airborne) not less than 50 and an Ln,w+CI (impact) not more than 62 if it separates sole-occupancy units.

Note:• Refer to Low Rise Multi-Residential Intertenancy Walls Design & Installation

Guide for detailed specifications and requirements.

The unique combination of thermal resistance, thermal mass, acoustic and fire properties make building with Hebel® a smart choice for meeting Australia’s stringent building regulations.

For low rise multi-residential dwellings, the Building Code of Australia (BCA) contains regulations covering fire, acoustic and thermal performance for buildings.

For detached housing, the BCA contains fire and thermal insulation regulations but no acoustic requirements. The thermal provisions are intended to bring new homes in Australia up to a 6-star energy rating standard. Builders can chose to meet the ‘deemed to comply’ guidelines or have the building rated under the state schemes - eg. BASIX, FirstRate, AccuRate or BERS software.

The thermal performance of a building depends on a number of factors such as orientation, floor space and size and aspect of windows. The R-Value of wall and floors can significantly affect the energy rating outcome of dwellings.

Hebel® provides a great springboard for walls and floors in energy rating systems due to its unique thermal properties of insulation and mass. Select AAC as the wall and floor option in these programs and see the impact that building with Hebel® can have.
