The resulting wood has a rather straight fiber with more or less marked veins ranging from medium to large. Compared to Oak tree red, the white oak it has longer medullary rays which give it a richer pattern.
That of white oak american (american white oak) is a hard and heavy wood, with a medium resistance to bending and compression, of low stiffness but very performing in steam bending. Due to these characteristics, the white oak it is widely spread and appreciated all over the world by many manufacturers of furniture, floors and finishes in wood which is also the oldest among building materials.
Other welcome characteristics of the wood of white oak American are the uniform color and the high volume of production of certified edged and sliced timber from controlled management forests according to an eco-sustainable strategy. Woods coming from European forests (for example Austrian or Finnish) or the United States always give good guarantees from an ecological point of view.
The wood of white oak it can also be used outdoors without conservative treatment because it has a 'moderately durable' Class 3 durability classification. However, in the presence of sapwood, the application of conservative treatment is necessary, but this applies to all woods.
The qualities of wood from white oak in terms of ductility, resistance, durability and aesthetics, they can be appreciated in various creations. One of these is the Shoffice (from the English shed + office - shed + office) that you see in the photograph, built on the back of a 1950s terraced house in St John's Wood in the city of London in the UK.
The designers of the London-based architecture firm Platform 5 Architects chose an external cladding in white oak American for its warmth, tactile appearance and durability. With wood of white oak the architects solved the question of the shape of the Shoffice and obtained a covering that can be used both internally and externally for the roof, walls and terrace. The weathered outer skin has not been treated and will discolour to a silver gray shade over time.
