Guest Presentation:
Russell Pedersen and Dan Reynolds of GIB
Russel introduced Dan who will carry out visits and presentations in person in place of Graham Robertson who is now partly retired.
Russel and Dan’s presentation focused on post event remediation of GIB systems, mainly following flood events.
GIB provides BRANZ approved literature on remediation and technical support through a helpline, training, and R&D. There is a useful booklet available online – search for “Assessing and remediating water damage to plasterboard linings”.
GIB will not provide advice on whether plaster boards need to be replaced, as there is a perceived conflict of interest. Water damage to plasterboard comes in 2 categories- clean water damage, such as from leaking water pipes, and dirty water damage such as from flooding or grey water. Plasterboards affected by dirty water always need to be replaced.
Boards affected by clean water may be dried out if the exposure has very been short and no degradation of the board has taken place. Sagging ceilings always need replacing.
It is always necessary to replace wet insulation, as insulation never dries out completely.
Remember maximum moisture content for closing in the framing is 18%. Treat the timber with paint on preservative. Steel framing needs to be checked for rust.
Check for mould. Mould can have long term health effects and samples should be checked out by a bio lab. Mild surface contamination can be neutralized with bleach.
- Do not rub, as the paper will be damaged.
- Where board replacement is necessary, remove the board to at least 300mm above the flood line. If that is less than 1200mm from the floor, replace 1200mm (or 1350mm if necessary) for a full width horizontal sheet.
- Check the bracing plan if available, and identify the board originally used. Replace it with an appropriate board and fixing pattern.
- Remember to use temporary bracing if necessary.
Steve Power of Resene Construction Systems
Steve focused his presentation on the Integra lightweight concrete inter tenancy walls which provide fire and sound separations. The system uses a 50mm Integra AAC panel which can have no penetrations through it. The panels can be laid in a stack or staggered bond and require mineral wool and fire rated building paper at the top under the roof or in the cavity.
The panels are supported by brackets between 2 @ 90mm framed walls, either steel or timber, featuring fiberglass insulation and plasterboard linings. The brackets are fusible to allow the framing to fall away from the AAC panel in the event of a fire, leaving the panel supported by the unaffected wall framing. To be effective, the system relies on the fixings for the brackets to come through the panel, so if the head of the fixing can be seen from the bracket side, the inspection should be failed. The fixings should start at 300mm up from the bottom and then at 600c and be staggered each side of the wall.
The system achieves 120/120/120 FRR and 64 STC.
Full technical literature can be found on the Resene systems website.
Bryan Newman of Resene Paints
Brian gave a quick overview of Resene Cool Colours. The system reflects the heat from the sun, allowing darker colours to be used in certain situations. The Cool Colours must be applied over a white undercoat to be effective. They can be used for re coating if the white undercoat is applied first.
