7.0 Fire Resistance Performance PowerWall

 CSR Hebel Detached & Low Residential Design Guide  No Responses »
Jun 292012
 

7.1 Overview

Hebel PowerWall 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 PowerPanel cladding protects the structural support framing, and provides a high fire resistance level for Hebel PowerWall.

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 FSV0356 is provided in Appendix D of this guide. Hebel PowerWall 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 Gyprock 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 PowerPanel 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.

7.2 Fire Performance of Hebel PowerWall

Hebel PowerWall 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 PowerPanel side. This excellent result enables Hebel PowerWall to be used in the following applications:

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

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

Fig. 7.1 Bushfire Area

7.3 Bushfire Areas

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

7.4 Design Considerations

Fire Stop Penetrations
Penetrations through Hebel PowerPanel to accommodate pipework, electrical cabling or ductwork 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 intumescent 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.

7.0 Sound Transmission & Insulation Party Wall

 CSR Hebel Party Wall Design Guide  No Responses »
Jun 192012
 

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+ C1). 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.

10.0 Design & Detailing Considerations Party Wall

 CSR Hebel Party Wall Design Guide  No Responses »
Jun 182012
 

10.1 Control Joints

Control joints must be provided at a maximum of 6m spacing. Recommended control joint widths should be 10mm minimum between Hebel PowerPanel and another building component.

Control joints must also be provided to coincide with any control joint in the main structure. Larger joint width maybe required to accommodate building movements, and these values shall be nominated by the designer. The top hat and back to back track must be discontinuous at a structural control joint.

10.2 Wet Area Wall Construction

Wet area wall construction requires a system that enables services to be installed in a cavity. All plumbing should be acoustically treated as required by the BCA. All wet area walls shall be lined and waterproofed in accordance with Australian standards and to BCA requirements. Gyprock Aquachek or Cemintel Fibre Cement Wallboard are suitable lining materials for wet area applications.

10.3 Non-Hebel Components Used in Party Wall

Components, which are not manufactured by CSR Hebel, such as CSR Gyprock plasterboard, timber and steel stud wall frames, CSR Bradford insulation and others must be designed, installed and handled in accordance with their manufacturer’s guidelines and recommendations.

CSR Building Products Limited, guarantees only the products that are manufactured by CSR Building Products Limited, not the components, products or services supplied by others.

13.0 Installation Guidelines Party Wall

 CSR Hebel Party Wall Design Guide  No Responses »
Jun 182012
 

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 PowerPanel™.

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 PowerPanel™ 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™ PowerPanel™

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.

15.0 Delivery & Storage Party Wall

 CSR Hebel Party Wall Design Guide  No Responses »
Jun 182012
 

15.1 Unloading Panels

Panels shall be unloaded and moved with only approved lifting devices. Before use, the lifting devices should be checked for the required lifting tags. Panels should be unloaded as close as possible to the intended installation area. This will increase work efficiency and minimise the need for secondary lifting.

Note: Secondary handling increases the risk of panel damage. The repair of damage sustained during lifting and moving is the responsibility of the lifter. Where damage is excessive, panels must be replaced.

15.2 Storage

All materials must be kept dry and preferably stored undercover. Care should be taken to avoid sagging or damage to ends, edges and surfaces.

All CSR Hebel products must be stacked on edge and properly supported off the ground, on a level platform. Panel bundles can be stacked two high. The project engineer should be consulted as to the adequacy of the structure to support the stacked bundles. Each bundle contains 10 panels (refer Detail 15.1). Where bundles are stacked two high, the supporting cleats must be vertically aligned, to ensure minimal bending of the lower panels. Refer to Detail 15.2.

If Hebel PowerPanel is stored outside, it must be stored off the ground and protected from the weather. Only single bundles positioned on the ground can be opened. To provide a level surface, we recommend placing temporary joists beneath the supporting cleats.
