WHERE IDEAS CAN GROW. Cross-laminated timber

WHERE IDEAS CAN GROW. Wood is naturally CO2-neutral and energy-efficient in all respects. As a building material, its positive properties help protecting against heat in summer and cold in winter. Its CO2-saving capacity significantly contributes to protecting our environment. If you use wood for building work you make a valuable contribution to the protection of the climate and the environment. In Austria, one cubic metre of new wood grows each second. One cubic metre of wood keeps one ton of atmospheric CO2 and thus helps to reduce the burden on our environment. A mere 10% more wood...

Cross-laminated timber Modern, ecological and flexible – developed to be used in constructive wood building. is a solid, structurally effective wooden element that also creates distinctive spaces. Thanks to its flexible dimensions and excellent physical building properties, it is suitable for any thinkable building requirements. The crosswise layering construction made of high-quality raw material with permanent bonding provides dimensionally stable and rigid building components. • Single and multi-family housing • Multi-storey residential housing • Addition of storeys • Urban aggregation •...

Different requirements call for innovative solutions Residential housing With its permeable type of construction, it is the most comfortable construction material in residential housing. Moisture-regulating walls not only provide for an optimal indoor climate, but also for excellent sound insulation. With its outstanding insulation properties, reaching a passive house standard is possible without any problem. Thermal insulation during summer is guaranteed, too. The walls and ceilings of the building shell already provide for warmth and cosiness. Furthermore, is a real space saver: Valuable...

Multi-storey buildings Due to the high load-bearing capacity, is an excellent choice for multi-storey housing and administrative buildings. The innovative construction material excels with very good building physics and fire safety qualities. In the field of earthquake safety, solid timber material offers decisive advantages compared to traditional brick and mortar buildings. However, enables not only the manufacture of components at storey height. With prefabricated crosslam elements, even entire residential units can be set up in a matter of a few days. Slim construction thicknesses...

crosslam is a large-format solid wood board with a multi-layer, crosswise-oriented profile. Structure and manufacture Finger-jointed and planed lamellas are loosely laid next to each other and the flat surfaces of the layers glued at right angles to one another. The structure is made up of at least 3 layers and would typically have a symmetrical layout. The layers are pushed together laterally to dimension before applying pressure in order to obtain a gap-free surface. To avoid uncontrolled stress cracks, the narrow sides are not glued. Gluing Depending on the requests of our customers we...

Values in bold letters indicate the main load-bearing direction of the slab. The main load-bearing direction may be in the longitudinal direction or cross direction of the slab. * In case of WSI (living space quality), the slab structure may vary in individual cases. ** only PUR - polyurethane glue ***Identical production only possible in pairs

Surface qualities Living space quality (WSI) Non-visible surfaces only apply functions in terms of load-bearing strength and building physics. No optical requirements are specified for these surfaces. Therefore subsequent panelling is recommended. For all surfaces meant to remain visible in residential building, with special requirements regarding a homogenous surface structure and lamella quality. This type of surface is especially applied in residential building, school and office buildings, if the principal wishes to have a homogenous appearance with wood as a natural material. • The top...

Loading and transport Loading plans Transport procedure In order to ensure an optimal assembly sequence of cross-laminated timber, it is necessary to determine a setup sequence during ordering already. According to this determination, simultaneously with the product release, a loading sequence is defined for the means of transport that will be used. The transport will be scheduled once the loading plans and delivery dates have been defined. Special transports are almost always necessary, because most of the loads contain components with lengths exceeding 13.60 m and widths and heights...

Packaging and storage The basic principles of wood storage must be taken into account for the elements: • Support blocks must be used • If components are stacked horizontally, alternate layers of wood with spacer laths • Store tilt-proof • Protective films to prevent the formation of condensation • Protect the components from rain, spray water and ground moisture by providing sufficient ground clearance and tarpaulins. • For longer storage, add sleepers to prevent creep deformation. Lifting systems elements may be provided with assembly aids. These are used to manipulate the elements at the...
