Vulcanisation & Vertical Grain Sawing
Outwud products are based on processes whereby sustainable wood species have been improved with regards to the most important challenges any wood product faces – Movement & Deterioration over time.
Outwud Vulcan+ cladding is based on Vulcanisation, a unique process developed & patented by a young entrepreneur based in New Zealand, Daniel Gudsell. It is a hi-tech combination of wood sawing technique, Thermal modification,
When exposed to weather, wood expands & contracts. The above combination minimises this movement extensively so that the end product looks & stays beautiful – free from excessive warping etc so common to normal woods exposed to harsh outdoors. Extensive field testing has been done in New Zealand and at projects all over the world, including India.
Besides being highly stable, Vulcan + cladding is also very durable. The chemical changes that take place in the wood during thermo-processing significantly reduce the contraction and expansion of the wood due to variation in its moisture content. This leads to a major improvement in the wood’s dimensional stability. Additionally, following the breaking down of hemicelluloses (sugar chains), wood no longer contains enough nutritional substances to support decay-causing fungi. This helps increase the life span of wood considerably.
The use of low impact opX treatment further enhances the protection against termites & fungus. opX technology is the world’s first water based, low toxicity wood preservative to combine azole fungicides with plant based oils and waxes for wood stabilisation.
An independent study by Graham Environmental found water borne azoles to be the lowest toxicity code compliant preservative in the H3 hazard class.
Outwud Sand + features vertical grain sawing which reduces movement as well as surface cracking (checking). It is also mildly heat treated to improve the colour tone however it is not thermally modified. In order to make it suitable for decking applications which is a higher risk situation (with regards to termites etc) as compared to cladding, it is treated with ACQ impregnation.
