8 Product Information

8.1 Storage and Handling

Care should be exercised in handling the QT EcoSeries Wall Panels to avoid any damage to edges, ends and faces. Panels must be stacked flat, off the ground and supported on a level platform. Plastic Shrinkwrap applied to pallets of panels for transportation from the factory, must be removed at the destination (i.e. distributors warehouse or direct to site) to allow panel to continue drying and equalise with local humidity. The panels must be kept dry at all times by storing under cover, or providing weatherproof covers to the stack. Panels must be dry prior to fixing. Intermittent weather exposure is not detrimental to the panel. However if QT EcoSeries Wall Panels become wet, allow thorough drying before fixing. Drying shrinkage may occur if the QT EcoSeries Wall Panels are not allowed to dry sufficiently. The proprietary Coating System must be applied and completed within 1 month from the date of installation of the QT EcoSeries Wall Panels.

QT EcoSeries Wall Panels and cement based renders, will release their salts and/or fines if saturated; this condition is know as efflorescence. In order to prevent efflorescence the cement products must be sealed to prevent the ingress of moisture and/or installed with careful attention to the weather-tightness details to prevent the ingress of wind driven rain, gutter overflow or moisture tracking along a surface with capillary action. The water that has permeated through the panel and render will collect and dissolve any salts and/or fines that are then released through hairline cracking in the render which are caused by hydrostatic pressure build up. The dissolved salts and/or fines will crystallise on the external surface. Should efflorescence occur, it is essential that the moisture source be eliminated and any hairline cracking repaired to maintain weathertightness. Refer to coating manufacturer for suitable surface repair techniques.

Panels must always be carried on edge. Any minor damage should be repaired with joint compounds or polyurethane foam. Fixings and other accessories must be stored so that they are kept clean, dry and undamaged. All components must be used within the designated shelf life. Any damage to Clips and Channel may affect the integrity or performance of the wall system. Panel may be cut with an electric circular saw 60 pt tungsten tip blade, diamond blade or handsaw. Panels are best shaped with the use of an electric plane or a handrasping tool. Holes or services may be formed with the use of an electric fretsaw or drill. When power tools are used for cutting, grinding or forming holes in the panels, appropriate safety measures as set out under the heading of Health and Safety must be observed. All materials that are susceptible to deterioration due to plastics migration or alkalinity of cement base products must be protected (check with product manufacturer).

8.2 Quality Policy

QT Systems Pty Ltd is dedicated to delivering quality building systems for internal and external use on residential and commercial projects. QT Systems Pty Ltd is committed to ensuring that its Conpolcrete building products provide the highest standards and consistency by meeting the requirements of customers and regulatory authorities. This objective is met through the implementation of a Quality System, based upon the requirements of an internationally recognised quality standard: AS/NZS ISO 9001:2000. Continued testing and independent scrutiny will ensure QT Systems Pty Ltd continues to offer an eco-friendly alternative construction material that consistently provides outstanding performance.

8.3 Maintenance

Annual inspection of the exterior walls must be made to ensure they remain in a weatherproof condition. Checks must be made of the exterior coating system, sealants, flashings, control joints and any water-proofing systems. Should any repairs be required, seek remedial advice from the manufacturer. If the project is still under the statutory warranty period contact the appropriate body, or check with your insurer.

8.4 Limitations of the QT EcoSeries Wall Panel System

QT EcoSeries Wall Panels are not designed to provide bracing for the building. The internal linings or other specifically designed systems must provide external wall bracing.

QT EcoSeries Wall Panels are not suitable to be used for chimneys and flues.

QT EcoSeries Wall Panels must not come in contact with the ground for extended periods of time. The panel must not be used for retaining.

This Technical Manual is limited to residential construction, for other applications contact your QT Distributor.

Designers must check that the details in this Technical Manual meet their own specific design requirements. For use outside the scope of this Technical Manual, specific design may be necessary. The Architect, Designer, Engineer, Specifier and Builder, are responsible for specific design and should ensure compliance with the BCA.

8.5 Product Support

Installers are registered trades people, equipped to install the panel and its complementary accessories. These installers, acting as independent contractors, should be industry licensed trades people such as carpenters or dry wall installers who are familiar with the QT EcoSeries Wall Panel system and components. The authorized agent or appointed licensee shall supply all QT EcoSeries Wall Panel system components directly to the contracting or sub-contracting party. We recommend you seek advice from all manufacturers or suppliers, regarding correct installation and maintenance requirements associated with their products. Failure to comply with specification requirements, which may compromise the exterior coating, sealants, flashing, weatherproofing and waterproofing, will render any manufacturers warranty void.

QT Systems Pty Ltd regularly updates its literature to keep up with system and product developments, changing trends in design, and therefore reserves the right, to revise and change its technical information without notice.

8.6 Health and Safety

As with all cement based composite products, they contain crystalline silica. Breathing in
fine silica dust is hazardous and may result in bronchitis, silicosis (lung fibrosis) and lung cancer. Do not breathe dust, always contain dust during clean up and disposal i.e. place dust in a sealed bag. Safe working practice is to avoid contact with skin, eyes and lungs, e.g. full-length clothing including boots, P1 or P2 dust mask, and safety goggles to AS 1337. (Wash worn clothing regularly, each day). We recommend that you always seek advice for recommended handling, health and safety requirements for products or components by other suppliers and manufacturers. Consult your local Work Place Health and Safety Officer for specific advice. Also see Material Safety Data Sheets for specific products.
