Wood: a natural and renewable resource

Wood is the oldest construction material used by man, but since the end of the nineteenth century the introduction of materials considered more durable, such as steel and reinforced concrete, have seen a decline in its use. However, over recent decades, wood has made a comeback as a structural material thanks to the green architecture movement: as a renewable, biodegradable and recyclable natural resource, durable and resistant, wood is perfect for green building.

But wood’s resurgence is also thanks to the introduction of new construction types. The use of laminated wood has made it possible to overcome the dimensional, static and morphological limits imposed by the nature of a tree trunk, while maintaining all its structural qualities. Research has led to the creation of wooden insulation materials that can replace polymers such as polystyrene and polyurethane. The use of new products for the protection of wood has increased its longevity.

In the wake of developments in architectural design and new construction techniques, Illen is fully aware of how much a wooden structure can offer.
