Timber Preservation Systems

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 revolt 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 its distinctive blue colour.

Full impregnation of organic biocides

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.
