Timber Plus ProjectAdditional Opportunities.There are a number of additional opportunities to maximise the use of timber and timber derived productswithin the timber plus building. We have identified the following as offering potential:-CEILINGS:Atkar Au.diPanel round hole perforated MDF or ply ceiling panels available from Asona Ltd. with prefinishedtimber grain and decorative surfaces, IAB acoustic tissue backer and edge profiled. Manufactured inAustralia.INTERIOR WALLS:Woodwool acoustic insulation products to reduce reverberation times within room.INSULATION:Insulation created from cellulose fibres could be used to insulate ceiling and external wall cavities with integralfire retardants as necessary.FLOORS:Linoleum sheet flooring could be used to bathroom and kitchenette areas. Linoleum is manufactured fromrenewable resources including wood flour, cork flour, jute, linseed oil and natural resin. The expected life spanis 30 years. Available from Tarkett flooring Ltd. Manufactured in Italy.Timber overlay flooring could be used throughout office and reception areas. FSC certified parquet flooring isavailable from Ekowood Ltd. The expected lifespan is 60years+ when well maintained (it can be re-sandedand re-finished up to three times) and it is warranted for 25 years. Manufactured in Malaysia from NewZealand Pinus Radiata with a sustainably sourced tropical timber wearing layer.Wood fibre acoustic Insulation panels could be used beneath the overlay flooring to reduce inter-floor soundtransmission and reduce reverberation within office areas. Sonopan insulation panels are available fromLouisville Speciality Products Ltd. Manufactured in Canada.EXTERNAL:There is an opportunity to construct a timber deck on bearers leading up to the main entrance in place of thesolid timber on slab that is currently shown. This may not increase the timber component but would reduce theconcrete used in the building. Options would be:-• Pinus Radiata decking treated to H3.2 with a copper-based chrome and arsenic-free (CAF) treatmentsuch as ACQ (Alkaline Copper Quaternary). OR:• NZ red beech (Nothofagus Fusca) which does not need additional chemical treatment in deckingsituations. H3.2 ACQ treatment to posts in contact / below ground. Red Beech could also be usedas the flooring to the entrance foyer to provide a seamless entrance showcasing one of NewZealand’s most beautiful timber species.Page 20 of 21 May 2008
