1 Wood Protection Australia The Specifier s guide to TANALISED preservative treated wood products

2 Purpose This document is designed to assist producers, resellers, specifiers and end-users of treated wood products to better understand the appropriate application of industrial wood preservatives for various end-use situations and types of wood products. Our range of industrial wood preservatives are only for use in suitably constructed and authorized industrial wood treatment sites and are not available for use by consumers or the end-user. For further details on treatment processing with and general industrial use of wood preservative products contact Lonza Wood Protection. H2 H2F H2 H2F H1 H1 H5 H2 H2F The range of Tanalised wood and timber products cover applications in all the hazard levels listed in the AS1604 series. It is important to understand that treated timber and wood products must not be used in a situation at a higher hazard level than that for which it was branded. For example, timber branded for application should not be used in ground contact (), and timber branded is not to be used in an H5 application. Marine water contact or H6 is the most challenging environment for treated wood. It is strongly recommended that specialist advice is sought prior to specifying treatment for marine or brackish water contact.

3 Tanalised Wood Products The Case for Built-In Durability Wood is a versatile construction material that has many benefits over alternative materials with regard to net environmental impact, cost effectiveness and ease of use. It is the only significant building material whose production and use can result in a net positive carbon storage balance as the wood fibre is created by photosynthesis where growing trees absorb atmospheric carbon dioxide. Managed plantation forestry is the most sustainable way to produce wood fibre for manufacture of timber and wood products. Australia has a strong plantation forestry sector mainly utilising exotic species such as Radiata pine among others. These trees are highly suitable for manufacturing a wide range of structural and appearance building products. However, in many applications timber and wood products require protection from natural biological agents such as mould, decay fungi, termites and other insects. Durability and reliability in service alongside good design and construction practices are key considerations in determining the suitability of building materials. The best way of ensuring the durability of timber and wood products against decay and/or insect attack is by industrial preservative treatment. Our Tanalith and Vacsol brand preservatives have been leading wood protection treatments in Australia for over fifty years. Tanalised means that a timber or wood product has been protected against decay and / or insects by incorporation of a Tanalith or Vacsol wood preservative from Lonza Wood Protection and processed through an approved industrial facility in accordance with Australian or other recognised standards. Lonza Wood Protection and our customers take pride in ensuring that Tanalised timber and wood products are safe to use, fit for purpose and supplied in conformance with relevant standards. Tanalised is the modern and reliable form of decay and insect protection for timber and wood products.

4 Tanalised Frame Protection Termite resistant structural timber and engineered wood products The need for wood durability has been shown in recent years with the focus on damage to buildings by termites in many parts of the country. Termites are a significant threat to the built environment in most parts of Australia and the Building Code stipulates appropriate protection measures are taken in affected regions. Scientific and pest control industry sources confirm that the incidence of termite attack in houses and other buildings appears to be increasing for a variety of reasons. Protection of key structural timber and wood based building components with the built in durability of a Tanalised treatment can play an important role in reducing the consequences of termite attack. Specifying Tanalised protection for timber and engineered wood products is an excellent way of ensuring that wood based building components have an appropriate level of durability given their intended function, the degree risk from termites and the time period for which the product is required to last. Testing by the CSIRO and other research organisations has shown that termites are highly averse to attacking correctly treated timber and such protection is capable of lasting for many decades even in challenging environments. Timber products treated to H2 or a higher level are deemed to be termite resistant building materials according to the Building Code of Australia and AS Termite management New building work. The specifier should be aware of the following considerations when specifying Tanalised termite resistant timber and wood products. There are two types of H2 treatment approved under AS1604 series. H2 level treatment applies to all areas of mainland Australia including the tropical north. However more commonly there is also H2-F (or H2-S) sub-category for framing timber and other interior structural wood products but this category should only be used south of the Tropic of Capricorn (see map). See AS or contact Lonza Wood Protection for further information. Note that any of the Tanalised framing treatments also A Tanalised H2 treated timber structure provides insurance that the structural integrity of the building will not be compromised even if termites breach the primary barriers. The additional cost of Tanalised protection of structural timber for an average house is only a fraction of the typical repair costs where termites cause structural damage. provides protection against European house borer (EHB). H2 or H2-F treated timber is suitable for dry, interior weather protected applications only and must not be used in wet or weather exposed applications. If protection against fungal decay as well as termites is required for a damp area or an exterior exposure (eg: window frames) then level treatment should be specified for those components. Timber species Not all timber species are suitable for H2 treatment. Most pine species and some hardwoods are suitable but advice should be sought from the supplier or Lonza Wood Protection regarding other species. A wide range of solid timber and engineered wood products such as plywood, I beams and laminated veneer lumber (LVL) can be supplied with Tanalised protection.

Design and build in a termite barrier system conforming to AS Design and build in durability for all concealed structural timber and wood components with Tanalised H2 treated termite resistant timber products. Design and build in ease of inspection for ongoing maintenance. Most of the mainland areas of Australia have a termite hazard and protection of new buildings or extensions is required under the building code in these areas. Many populated areas have a high termite hazard as determined by a CSIRO survey (refer to the Termite Hazard Map). Painting: The Tanalised treatment may contain a red or blue marker pigment. Steps may need to be taken to avoid colour bleed if the timber is to be painted. Refer to Paint manufacturer s instructions and AS2311 The painting of buildings for further details. End cuts in timber used south of the Tropic of Capricorn need not be resealed in H2 applications. Refer to the application notes on the back page. Tanalised H2 treatments are non-corrosive to metal fasteners and do not significantly affect nail plate holding or plaster board adhesion. The Tanalised treatments do not affect the structural grading of the timber products.

6 Tanalised Outdoor Wood Protection Vacsol Azure - Solvent Borne Azole Based Timber Preservatives VACSOL AZURE is a new generation LOSP (Light Organic Solvent Preservative) treatment incorporating all carbon based and bio-degradable triazole and synthetic pyrethroid active constituents. Vacsol Azure provides effective protection against fungal decay and insect attack for above ground building applications including non-structural and structural wood products. the treatment solution and treated wood products. Uses: as per AS for protection of general structural and non-structural wood products above ground only. Note the above ground means at least 200 mm ground clearance and with good air circulation. Timber Species: Radiata pine, Slash pine (and similar). Painting: The solvent from the treatment may interfere with paint adhesion so it is important that the timber is conditioned after treatment before painting to ensure that any excess solvent has flashed off. In industrial production facilities pre-applying paint primer to the treated wood, this time may be accelerated by forced air drying, vacuum drying or other means. Many Vacsol Azure treated products are supplied with a factory applied primer coating and these should be suitable for immediate painting. The key benefit of Vacsol LOSP treatment process is that it causes no change in the moisture content, dimensions or structural grading of the wood products. Therefore it is ideal for the treatment of wood products that are finished to fine dimensional tolerances such as window joinery, cladding and trim boards. Water repellent and dimensional stabilizers in the treatment help retain dimensional stability of the wood in service. Similarly it is also ideal for structural or engineered wood products (such as LVL and laminated wood products) that are reliant on a specified, low moisture content for structural grading. For example, in many cases it is faster and more efficient to use the solvent based treatment rather than use a more conventional water based treatment and then needing to kiln re-dry or do other re-work on the wood after treatment. Lonza Wood Protection have recently introduced a new innovation in this technology with Vacsol Azure LO which incorporates a patented Low Odour technology. This option has all the traditional benefits of LOSP treatment but also has dramatically less perceptible odour from

Clear - 64 Clear or green - 64 Clear or green - 64 For timber supplied with no factory applied primer, it is recommended to allow it to condition for a few days with good air circulation before painting. Plywood and LVL: Due to the nature of plywood and LVL it is recommended that additional conditioning time is allowed for depending upon drying conditions, the types and thickness of plywood or LVL used. If in doubt, test paint a small area first to check for satisfactory adhesion. Fasteners: Vacsol Azure treatment is not corrosive to steel or other common metals so no deviation from normal practice is called for. However corrosion resistant fasteners are recommended for all exterior or weather exposed timber work.

8 Tanalised Outdoor Wood Protection Tanalith Copper based preservatives Water Borne alternatives for in-ground use Lonza Wood Protection offer copper based preservatives for protection of wood and timber products in general outdoor and ground contact use. These are environmentally advanced timber preservatives that incorporate copper in combination with an azole or quaternary ammonium compound co-biocide wood protection system. The Tanalith copper based preservatives conform to the latest Unites States EPA, European Union and Australian directives regarding suitable wood preservative products for residential and close human contact use. Copper based preservatives are in wide use around the world including many countries in Europe, the United States and more specifically Japan, South Korea, Taiwan and New Zealand in the Asia Pacific region. Uses: Copper based preservatives are ideal for common above ground () and ground contact (, H5) applications that require robust levels of protection but where there may be sensitivity to arsenic or chromium containing preservatives. Examples are outdoor and garden furniture, decking, playground equipment, hand rails and landscaping in schools, public facilities or other areas where high levels of direct human contact are expected. Timber Species: Tanalith E and Taratek are suitable for treatment of most common soft-wood and hardwood timbers. Lonza Wood Protection can provide a number of options for copper based preservatives; Tanalith E Wood Preservative uses copper as a solution in combination with azole co-biocide (as tebuconazole or tebuconazole + propiconazole). Tanatone Terra Rossa is a red-brown colour system that can be added to Tanalith E Wood preservative to provide a single step in plant preservative and colour treatment. Taratek Alkaline Copper Quaternary Timber Treatment uses copper as a solution in combination with a quaternary ammonium co-biocide (DDAC).

This can be snaded or washed off and does not impact on the properties of the wood. Fasteners: Copper based preservative treatments may be slightly to mildly corrosive to steel and other metals in contact with the treated timber. Galvanized steel or other corrosion resistant fasteners are recommended for all weather exposed or ground contact situations. Stainless steel fasteners and connectors (or other metals of high corrosion resistance) should be used for critical applications where very long service life is required or where additional sources of corrosion are present, such as salt. The treated wood should not be installed in direct contact with zinc-alum sheet roofing as corrosion may result. Use of pre-painted roofing and installation a durable water resistant membrane between the materials is recommended. Painting: All Tanalith treated timber can be painted like normal timber once dry and clean. Painting or staining of dimensioned timber in exterior, weather exposed situations is strongly recommended to minimize surface mould, checking, sun bleaching and dimensional movement. Tanalith E is available with Tanatone Terra Rossa in-treatment colouring system that delivers a pleasing midbrown colour to the treated wood.

10 Tanalised Outdoor Wood Protection Tanalith CCA A proud record of service CCA stands for copper, chrome arsenate and this remarkable wood preservative has been in use for over fifty years. It has stood the test of time and even today is still preferred where wood products require protection in high hazard situations. Tanalised CCA is the longest serving and most widely used timber treatment in Australia, New Zealand and many other parts of the world. Even where CCA has been withdrawn from residential applications, it is generally retained for utility, structural and rural uses where low maintenance and high durability are essential. The unique properties of Tanalised CCA make it the Ideal choice where treated wood products must have the highest levels of durability and engineering safety. Examples are engineered retaining walls, bridges, safety barriers, building and utility poles, foundation piles, sea walls, marine piles and industrial applications such as cooling tower fill. Tanalised CCA is ideal for rural and agricultural applications such as vineyard posts and hail net poles. The APVMA conducted a review of CCA preservative in Australia and has determined that while there is no specific information indicating that CCA treated wood poses unacceptable risks, on a precautionary principle CCA should not be used for the treatment of timber and wood products to be used for certain applications such as playground equipment, handrails, picnic tables, park benches, garden furniture and residential decking. This regulation came into effect in March Of course, Tanalised CCA can still be used for all other normal domestic construction and landscaping applications although Lonza Wood Protection suggest that alternatives such as Tanalised Ecowood or Tanalised LOSP may also be considered in these cases. Tanalised CCA is suitable for application in all the hazard levels listed in AS1604 Specification for preservative treatment (refer to hazard level guide). However it is important to understand that timber should not be used in a situation at a higher hazard level than that for which it is branded. In particular, Tanalised CCA timber branded for application should not be used in ground contact (). Tanalised CCA timber branded should not be used for structural or critical in-ground applications (H5). Structural or critical use in-ground applications include foundation piles, building poles, engineered retaining walls, permanent fresh water contact and certain industrial applications such as cooling towers. Marine water exposure (H6) is the most severe service condition that timber is subject to. However the exact product requirements vary depending on the site (southern or northern waters). It is strongly recommended that specialist advice is sought prior to specifying for H6 applications.

11 H5 H6 Tanalith CCA treated wood application guide Hazard Level Softwood Hardwood H5 H6 southern waters (1) H6 northern waters (2) (3) 1 Southern waters may be considered to be those on coastal regions of Australia below 35 degrees latitude. 2 Northern waters may be considered to be those on coastal regions of Australia above 35 degrees latitude. See AS section 7 for further details. 3 CCA can be used in conjunction with creosote for northern waters see AS Table H6.1 and Table H6.2. Tanalith CCA is designated as preservative number 01 under AS The specifier is advised to be aware of the following considerations when specifying Tanalised CCA. Timber species: Tanalised CCA is available in common hardwood and softwood timber products. Sawn softwood timber such as radiata or slash pine for use in structural applications should be dry (<16% moisture) at the time of supply. Ensure that if structural Tanalised CCA pine is required that an appropriate structural grading (ie: MGP10) and dry after treatment is specified. Fasteners: Galvanised steel or other corrosion resistant fasteners are recommended for use in all weather exposed or ground contact situations. Stainless steel fasteners and connectors (or metals of high corrosion resistance) should be used for critical applications where very long service life is required and where additional sources of corrosion are present such as salt. Tanalised CCA should not be installed in direct contact with or over zincalume sheet roofing as corrosion may result. Use pre-painted roofing or install a durable water resistant membrane between the materials. Tanalised CCA off cuts and redundant pieces are not a hazardous waste. However it is recommended that care is taken to dispose of this waste properly (as solid waste). It should not be mixed with green waste for composting and MUST NOT be burnt as toxic fumes or residues may be produced.

12 Tanalised Outdoor Wood Protection Vacsol K The oil that s good for wood Vacsol K is creosote, one of the first and most reliable wood preservatives ever used. Creosote is an oil distilled from coal tar and is a complex blend of hydrocarbon compounds. Creosote has unique advantages as a wood preservative for many rural and industrial applications. Creosote and CCA are the only two preservatives suitable for marine waters or Hazard level H6 applications. Coal tars and creosotes have been used for well over a century throughout the world as wood preservatives. They combine broad range protection against wood destroying fungi and insects including termites. Being insoluble in water, creosote is resistant to leaching and improves the weathering durability of wood. A further advantage is that creosote improves the fire resistance of wood. Note that creosote is an industrial or rural use preservative only and is not suitable for residential use. Vacsol K treated wood application guide Hazard Level Softwood Hardwood H5 H6 southern waters (1) H6 northern waters (2) (3) Restrictions apply on some end-use applications and it is not recommended to be used for treatment of wood products where frequent and direct human contact will occur. Uses: Creosote is suitable for treatment of wood products used rural and industrial situations only. Examples are fence and vineyard posts, utility poles, foundation piles, bridge and other heavy engineering timbers and marine water contact applications such as wharf piles and fenders. Timber Species: Creosote is suitable for treatment of most common soft-wood and hardwood timbers. Painting: Creosote treated wood is not suitable for painting. Fasteners: Creosote is not corrosive to metal and the oil will help mitigate corrosion. However galvanized steel or other corrosion resistant metal fasteners and fixings are recommended for all exterior applications. Handling: Contact with creosote treated wood may cause skin irritation or burning. Additional measures to protect skin will be required when working with creosote treated wood. Consult the wood supplier for further details. 1 Southern waters may be considered to be those on coastal regions of Australia below 35 degrees latitude. 2 Northern waters may be considered to be those on coastal regions of Australia above 35 degrees latitude. See AS section 7 for further details. 3 Creosote can be used in conjunction with CCA for northern waters see AS Table H6.1 and Table H6.2. Vacsol K Creosote is designated as preservative number 20 under AS

13 Tanalised Wood Products Built in Durability Additional Application Notes Identification and branding: Tanalised protection cannot be applied by the end user or on site. A conforming Tanalised treatment can only be provided by pre-treatment in dedicated industrial facilities. All treated wood and timber products should carry a treatment brand that identifies the treatment or hazard level to which the product has been treated, the preservative used and the identity of the treatment provider as follows; Moisture content: Structurally graded timber (Radiata pine) should be supplied with moisture content less than 16%. Most general outdoor and ground contact treated wood products will be supplied wet (moisture content > 16%). Contact your wood supplier for details. Reworking after treatment: Treated wood and timber products should not be re-sawn or re-sized after treatment by end users (except for cutting to length or notching as required for fitting and joining). These processes may reduce the protection afforded by the treatment. Where timber is cut or rebated in, and H5 situations, the exposed area should be resealed with a suitable in-can protective such as Tanalised Ecoseal, or Tanalised Enseal for general above ground situations to ensure that an integral protection envelope is maintained. For ground contact or for heavy engineering timbers, Arch CN Timber Oil and Arch CN Timber Protective Emulsion are recommended for resealing cuts, notches and holes. Where possible for situations it is recommended not to place a cut end in ground contact. For H5 applications a cut end must not be placed in ground or water contact. No cutting or notching should be done after treatment on H6 level treated timber in the water contact zone. Maintenance: Painting and staining improves the appearance and dimensional stability of treated wood and timber products. It is strongly recommended that all finished and sawn timber in weather exposed applications is painted, stained or sealed to reduce surface deterioration, checking or dimensional movement. Tanalised timber (except for creosote) can be painted or stained like normal untreated timber providing that it is dry and clean. If a transparent finish is desired, Lonza Wood Protection recommends the use of Tanacoat oil to obtain the best performance with Tanalised treated timber. If a solid finish is desired then always follow the paint manufacturer s instructions. Nails, bolts, fixings and metal in contact with wood: Corrosion resistant fasteners, fixings and connectors should be used for all timbers where weather exposed, damp or ground contact applications.

Safety Data Sheets (SDS) and other safe handling information resources for wood preservative products are available from Lonza Wood Protection. Wood preservative processing is a notifiable activity requiring appropriate trade or site use consents. considered to be a hazardous waste. However, care should be taken to dispose of this waste appropriately through normal disposal services. Treated timber wastes should not be mixed with general green waste for composting. Treated timber should not be burnt as a means of disposal and not used for cooking or home heating fuel. Industrial timber treatment plant facilities are required to conform to strict environmental regulations and are under the jurisdiction of state environmental protection and / or regional authorities. Treated wood and timber products are safe to use however as with handling many materials, certain precautions should be observed, particularly where machining or sanding generates wood dust and air borne residues. Keep work areas clean, avoid accumulation or inhalation of wood dust and wash hands after handling the materials. Contact the treated wood supplier for specific advice.
