Pine
2 usd/kg
Pine ranges from light brown heartwood to white sapwood, with conspicuous growth rings. It has moderate strength and good machining properties – and a distinctive resinous smell when worked. It is a lightweight softwood that comes from evergreen coniferous tress. These trees can be fast growing, which makes them popular for timber plantations – although this can reduce the benefit to environment of these trees removing CO2 from the atmosphere. The wood is used in everything from construction (timber frame, non-structural, engineered wood, plywood, cladding, window frames, doors, interior panelling), through to furniture, wood fibre products and paper. They are vulnerable to decay and so are primarily used indoors. They are treated (pressure-impregnated) to make them rot resistant, but will not last as long as other more hardy species, such as larch, oak and chestnut. Pine tends to be a little stronger and more durable than spruce, which is used in many of the same applications. In Europe, they are differentiated as redwood (ER) and whitewood (EW), respectively.
Accoya wood is modified radiata pine. Sustainably sourced from certified forests, radiata pine is a fast-growing softwood that is not as durable as slow-grown and tropical hardwoods. Through a process of acetylation, the chemical structure of the wood is altered, resulting in a dimensionally stable and extremely durable timber guaranteed for 50 years above ground and 25 years in ground or freshwater. The process does not add any toxins to the environment. Accoya is used in windows, doors, siding and cladding; inside and outdoors. It can be left untreated, painted, or charred.
