Timber treatment

Design Pine is pre finished removing a pre painting preparation. Coated with the true primed blue surface Design Pine allows for the direct application of solvent based or acrylic finishing coats. The organic preservative used in Design Pine offers above ground (H3) protection. The preservative use in the pre finishing processes utilizes organic chemistry to minimize environmental impact.


What makes Design Pine different?

The organically based timber preservative is a highly efficient and successful means of treating and protecting cut timber. However, the removal of excess solvents from the process can leave residues of resin acids and waxes on the surface, which may transfer through normal, high quality, solvent borne primers causing over coating problems with waterborne topcoats.

Design Pine© is coated with a new high quality solvent borne primer which has been developed over 3 years by Resene. This new Design Pine© primer has been extensively evaluated for compatibility with all major Australasian topcoats and has proved to be successful.

Design Pine© also helps to prevent moisture transmission, improving the overall water and humidity resistance of the timber.


The product

Design Pine© is produced by finger jointing and laminating radiata pine which is generally straighter, stronger and easier to use than solid radiata.

Add the organically based timber preservative and the product becomes a highly durable timber able to withstand hazardous conditions including attack from wood boring insects and decay fungi.

Design Pine is the name given to the ITI range of finger jointed and laminated radiata pine.

Design Pine is covered by a 25 year limited guarantee and can be identified by it's distinctive Blue colour.

The Timber Preservation System

The preservative system used in Design Pine offers above ground (H3) protection. The preservative is described as an organic system, utilising the active ingredients permethrin, propiconazole and tebuconazole, representing the most recent developments in Light Organic Solvent Preservative technology.

This technology is ideal for the treatment of structural timber and architectural features (such as external joinery and profiles) where accurate gauging or profiling is required or where structural requirements necessitate a durable, 'dry-after-treatment' timber product.

Typical examples include exterior structures such as pergolas and balconies as well as laminated posts and beams, feature profiles, reveals and facia. These all fall into exterior above ground situations or hazard level H3. This specification for preservative treatment resists both fungal decay and termite attack.

Increased awareness of these factors and demand for dry-after-treatment timber has prompted renewed interest in the organically based LOSP Azole treatment. Unlike traditional water based treatments this system does not affect the dimensional stability during treatment.

This vital attribute has helped promote the modern revolution with finger-jointed, laminated, and engineered timber products for exterior applications.


Questions and Answers

A. Present day timber supplies are increasingly being sourced from fast growing plantation softwoods such as radiata pine. These exotic pines have a number of advantages such as lightness, ease of use and uniformity. However they have little natural resistance to termites and fungal decay. Fortunately these softwoods are ideal for timber treatments, which provide them a high degree of resistance to fungal decay and termites.
A. No, H3 treated timber is only suitable for use in applications which can be described as "exterior or subject to moisture and above ground" or hazard level 3. It is not suitable for ground contact applications (H4).
A. .The Azole based LOSP system conforms with Australian Standards (AS1604) for exterior use on your home. Design Pine also conform to the structural grading as marked, or as advised by the supplier as the treatment does not affect timber strength.
A. Like all dry, dimensioned timber, Design Pine should, as far as possible, be protected from rain and weather prior to construction to prevent unsightly surface mould or other aesthetic blemishes. Storage areas should have good ventilation to minimise any odour or residual solvent vapours.
A. No. A study by the Queensland Department of Primary Industries Forest Service has shown that pressure treatment of slash pine using light organic solvent preservative has no negative effect on the stiffness and strength of the wood.
A. The treatment is expected to last well in excess of 25 years providing that the product meets specification and the timber is installed and maintained correctly in the right hazard application (exterior above ground situations).

A. Yes, all our timber products are safe when used and handled as recommended. See separate MSDS.

It must also be considered that individuals have a wide range of sensitivity when exposed to many natural and man-made materials. In rare cases the preservative, the wood itself or other additives may cause irritation to some individuals particularly in form of sawdust or if the timber is not dry.

If any irritation or undesirable effects occur, cease handling the material and review your work procedure and personal protection measure (i.e.: gloves, dust extraction). If irritation persists consult your doctor or an occupational health adviser.

A. Yes, all Design Pine products are sourced from renewable plantation pine forests where numerous studies have found that timber sourced from well-managed resources has a low net environmental impact, much lower than most man made materials including steel, aluminium, plastics and many masonry products.

The use of the preservation system provides an additional advantage by greatly enhancing the durability of the timber. Essentially, fast growing plantation softwood is converted into the equivalent or greater durability of naturally durable, slow growing indigenous timbers.

In summary, use of Design Pine is environmentally responsible.
