Lightweight yet very strong, with superior acoustic, fire, seismic and thermal performance, CLT is also fast and easy to install, generating almost no waste onsite. In order for structural wood elements to be considered ‘mass timber’, they must meet minimum size requirements, which are different for horizontal (walls, floors, roofs, beams) and vertical (columns, arches) load-bearing elements and dependent on the number of sides that the element is exposed to fire. Mass timber is also lighter and can be built on urban land, e.g. It is comprised of multiple solid wood panels nailed or glued together, which provide exceptional strength and stability. The term 'timber frame' typically describes a system of panelised structural walls and floors constructed from small section timber studs, clad with board products, in which the timber frame transmits vertical and horizontal loads to the foundations. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material.
