6 Fire Rated Construction Details QT Eco Series

April 15, 2013 by

Note: Prior to any firewalls being constructed it is essential that the builder consults with the project certifier to ensure that the certifier is aware of the firewall construction procedures and the certifier deems the installer competent.

Fire Resistance Level (FRL) is assessed by three performance measures:- Structural Adequacy / Integrity /Insulation eg 90/90/90

6.1 FRL – 90 Mins. & External Fire Source

CSIRO Full-Scale Fire Test FS 3685/2695 has proven that the QT EcoSeries Wall System (shown right) is capable of achieving a fire resistance of 113 minutes Integrity and 115 minutes Insulation when tested in accordance with AS1530.4. Therefore for the purpose of Building Regulations in Australia, the QT EcoSeries Wall System achieved a fire resistance level (FRL) of 90/90/90. The FRL is applicable for exposure to fire source from the tested side (QT EcoSeries Wall Panel side).

The Fire Rating information for sections 6.2, 6.3, and 6.4 are based on CSIRO Opinion FCO-2310 Dated 17th February 2004.

6.2 FRL – 90 Minutes

To achieve a 90 minute Fire Rating the wall must be constructed so as the wall consists of two layers of 13mm thick fire resistance plasterboard affixed to the timber frame internally and one layer of fire resistant building foil, one layer of 50mm QT EcoSeries Wall Panel with a 5-8mm render applied with finish, affixed directly to a 20-50mm battened out cavity. This system would be capable of achieving Fire Resistance Levels of -/90/90 for Non Load Bearing walls and 90/90/90 for Load Bearing Walls designed in accordance with AS1684 for fire exposure from either direction if tested in accordance with AS1530.4

6.3 Extended Wall Areas

The Fire Resistance Levels of 60 & 90 minutes would still apply to the same system extended in height in modular form provided that the structural members are designed in accordance with the relevant structural design code for the height and load of actual installation and an approved joint system appropriate to the FRL and the width of the gap is used for the horizontal and vertical joints in a manner as detailed in the attached drawings.

Columns & Capitals BGC FIBRE CEMENT

April 11, 2013 by

BGC Columns & Capitals can be used for architectural columns, posts, construction formwork and decorative external or internal fixtures and fittings.

The columns are primarily intended for decorative non load bearing applications but can be used in specifically designed load bearing applications and as permanent formwork for a range of steel reinforced concrete structures.

BGC Columns:

are smooth and have a pre-primed surface ready for paint
are lightweight and quick to construct
can be cut with timber cutting tools
easy to drill
an extensive range of capital accessories to compliment or enhance many architectural styles is available
100% recyclable
environmentally friendly

10.0 Design & Detailing Considerations Party Wall

March 28, 2013 by

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.
