Cross laminated timber
What is Cross laminated timber (CLT)?
Cross laminated timber (CLT) consists of at least 3 and a maximum of 9 layers of spruce lamellae laid crosswise and glued together flat, generally with a symmetrical structure. These large solid wood panels are especially used for wall, ceiling or roof elements in modern timber construction. Gluing is done with PUR adhesive made by Purbond, a formaldehyde and solvent-free glue approved for the production of load-bearing wooden components.
The solid wood elements are precisely cut to size on the latest CNC timber framing machines according to plan. These produce large components with a thickness of 63 to 292 mm and formats up to 3 m x 15 m. The ready-for-assembly, trimmed elements are ultimately delivered to the construction site just-in-time.
Cross laminated timber (CLT) is suitable for load-bearing, bracing and non-load-bearing wall, ceiling and roof elements. The elements can be individually adapted to the demands made on structural design, fire protection, noise and thermal insulation and are therefore very well suited for public buildings such as schools, children’s nurseries, as well as for detached single-family homes and apartment blocks, office and commercial buildings. Cross laminated timber is used in utilisation classes 1 and 2, i.e. it may not be exposed to direct weathering. Our own in-house monitoring and external checks by accredited testing and monitoring bodies guarantee the high product quality.

Dimensioning programme for BSP
The free-of-charge dimensioning programme for ED-BSP cross laminated timber supports you when planning your cross laminated timber projects. This programme can be used to dimension the cross laminated timber elements according to static loading. The basis for the CLT designer is the Eurocode 5 with the national appendices for Germany and Austria as well as the Tymoshenko method and the research results of the Technical University of Graz.
Simply use the form below to register so you can immediately gain access to the CLT designer via email. The programme requires the installation of Java SE Runtime Environment (JRE 8).
Cross laminated timber (CLT) planning & timber framing
3D CAD planning
Planning and work preparation
The planning and work preparation is carried out by our own employees at the company. Since they worked previously as carpenters, they also have the professional knowledge for assembly work.
- Professional planning
- Individual project development by having direct contact to a designated contact person, short information channels
- Designing with Dietrich’s timber construction software
- Optimal and practical detailed solutions, technical project advice
- Basis for 3D CAD planning may be plans in paper form and pdf files, or for direct data import: dwg, dxf, sat and ifc files
- Structural pre-calculations with the DC-Statik design software
- Visualisation in the planning phase, 3D tour through planned building, 3D pdf
- Flexible scheduling
CNC timber framing

- Special timber framing
Cross laminated timber (CLT) - Assembly
Assembling cross laminated timber
The ED BSP | structural elements cut to size according to plan are delivered at the construction site on the requested date and according to the assembly sequence, and a construction crane is used to unload and move them. An experienced timber construction company or carpentry firm takes care of the professional screwing of the external and internal wall elements and ceilings according to the information supplied by the structural engineer. As early as on the 2nd day, the building of a detached house can be completed with the roof. The exterior insulation is ideally done with wood fibre insulation boards. Whether plaster base boards and plaster or timber formwork is used, the builder can design the façade as he wishes. For the interior construction, plasterboard or gypsum fibreboards are recommended, but the timber surface can also remain visible. There are no limits externally or internally to architectural creativity.
- ED BSP | structural elements must be protected against the weather, moisture and dirt on the construction site with suitable means
- The large format components enable a fast assembly and ensure the building is well braced
- Component connections are facilitated by guiding grooves in inner walls, interlocking joints in external walls and damper cover strips in ceilings and roofs
- The component connections must be sealed according to recognised engineering standards.
- ED BSP | cross laminated timber is breathable. If the insulation and façade are also designed to be breathable, films acting as a vapour barrier are not necessary
