1. Design

1.1 Material Properties

• Total Square Metres per Panel = 2.0 m².
• Number of 50mm Panels per Pallet = 23 panels Pallet Weight:- 940kg (approx) (± 20 kg safety factor).
• Pallet Size – 900mm Width x 2250mm Length x Max. 1350mm Height (nom).

1.2 Thermal Performance

The Thermal performance of the QT EcoSeries Wall System is calculated in accordance with AS 2627.1 Thermal Insulation of Dwellings. QT EcoSeries Wall Panel has a k-value of 0.07 w/mk.

1.3 Impact Resistance

QT EcoSeries Wall Panel when coated with a cement base render, can provide resistance for hard body impacts typically found under normal situations.

1.4 Acoustic Performance

The QT EcoSeries Wall System was tested in accordance with AS/NZS 1276.1 for Airborne Sound Transmission and achieved STC41 and R_w41(-3;-8)(Wall Composition: 50mm QT EcoSeries Wall Panel with 30mm (nom) cavity on a 70mm x 35mm stud frame and 10mm plasterboard) CSIRO TL399. Acoustic performance can be significantly increased with the addition of bulk or acoustic insulation batts.

1.5 Fire Performance

QT EcoSeries Wall Panels when tested to AS/NZS 3837 and in accordance with BCA Specification C1.10a Section is classed as a GROUP 1 material.

1.6 Durability

In normal conditions and when maintained properly in a weatherproof condition, the cladding systems should exceed 30 years of trouble free serviceable life. When the system is installed in high corrosion zones, such as coastal locations within distances of up to 500m from the sea, particular care must be taken to ensure that openings through the cladding panels are kept to a minimum to prevent corrosive salt aerosols from entering the wall cavity and affecting metal components. (Permitted openings are base weepholes, soffit vents and openings beneath window joinery at sills).

Wildlife Attack

The panels will not support growth of micro-organisms such as fungi or bacteria and do not hold any nutritional value for ants or rodents.

1.7 Cavity

Cavities form an important role in the weathertightness and life cycle of any wall system QT EcoSeries Wall Panels constructed without a cavity will void any warranty. The cavity acts as a secondary barrier against wind driven rain penetration entering the wall framing. The cavity also allows the wall to ventilate and drain which is essential for a healthy wall.

1.8 Vapour Permeable Sarking

Vapour permeable sarking must be installed to the face of the building framing prior to installation of the battens and panels. The vapour permeable sarking has two main functions, weathertightness and thermal resistance. In its weathertightness role it protects the building framing from direct contact with moisture generated by wind driven rain penetration, while allowing the condensation of moisture from interior artificial heating and cooling to escape. Thermally the vapour permeable sarking divides the wall into two separate air spaces, which significantly increases the thermal performance of the wall.

1.9 Weepholes

On the first horizontal course (ground level) weep holes are to be installed at centres not exceeding 1200mm immediately above any damp proof membrane or flashing. Weepholes are also required in areas where there is a possibility of moisture build up. Weepholes must be limited to 8mm in width to reduce the potential for vermin access.

BGC Duraliner is a general purpose fibre cement building board designed for flush jointing.

It has been specially formulated and prepared to meet the requirements for use in wet areas, internal linings, ceilings, a substrate for ceramic wall tiles and fire & acoustically rated internal walls.

BGC Duraliner can also be used on external applications, such as soffits, where it will not be subjected to the direct actions of the weather.

Duraliner:

• can be used for a wide variety of applications
• perfect as internal lining in wet areas
• can be used as part of fire and acoustic rated wall systems 
• sheet is face coated with a green tinted sealant
• rebated on 3 edges for ease of jointing and installation

*some sizes may not be available in all states, please check with your local BGC office for availability.
