The new nature of architecture

Cross laminated timber is a solid pre-fabricated system element made from wood. CLT combines the many advantages of wood with technological achievements that enable a high degree of prefabrication and rapid, safe construction. Compared to its weight, it is one of the most capable construction materials for multi-storey buildings such as residential buildings, commercial buildings (offices, hotels), municipal buildings such as schools, kindergartens or nursing homes and much more. Further applications are extensions or upgrades of any kind and dimension in urban environments. And let’s not forget about private residential construction. The refinement of wood into CLT combines fast and precise construction with the aesthetics, comfort and sustainability of wood.

Production

CLT consists of three to seven cross laminated softwood board plies. By gluing longitudinal and transverse plies, the swelling and shrinkage of the wood is reduced to a negligible extent. Pfeifer CLT uses dried, planed spruce and pine lamellas sorted by strength and quality as well as formaldehyde-free polyurethane (PU) glue. The individual panels are connected lengthwise by a finger joint in a force-fitting manner and finalised in the gluing station or press. In the joining centre, CNC-controlled joinery and sanding takes place according to customer specifications. The entire Pfeifer CLT production is highly automated.

Pfeifer offers large-format, completely joined and sanded CLT elements up to 3.10 m wide and 14.5 m long with thicknesses from 6 to 30 cm and three to seven laminated plies.
