From innovate treatments that improve the durability of timber and timber products, to new products designed for specific applications and connections that reduce assembly time and costs, this is an invaluable resource.View
The concept of WoodHeart is to utilise the pine heartwood content in all the externally exposed surfaces of windows and doors where high stability and durability is needed. WoodHeart logs are sawn taking into account end use profiles, ensuring best possible use of the heartwood. During the production of components, small amounts of sapwood will remain in the final component.To ensure best performance and to remove the need for chemicals, this sapwood should be orientated to the inside of the window or machined away during profiling.
Benefits for windows and doors are summarised as follows: Good dimensional stability, high durability, stable base for coatings, good visual aspects, good strength properties, high insulation values and environmentally sound.
WoodHeart is a special product for a limited range of applications. To produce a completely sapwood-free component will lead to a high material cost.
Limited application in Australia for easily treated plantation softwoods, but may increase as we try and utilize small diameter plantation hardwoods. Definite opportunity for cypress which has refractory (can't treat) sapwood, but highly durable heartwood. In this regard, opportunities would be verandah posts and components similarly exposed to the weather.
Structurecraft are a contractor specialising in the engineering, design detailing, supply and fabrication of complex, large and challenging timber structures. Though there is nothing especially groundbreaking about the panelized systems that they use, they occupy a worthwhile link in the supply chain that largely does not currently exist...
