Timber framed construction

It is produced from pine and spruce. In the production process we use structural timber in strength class C24 and C24M, solid structural finger jointed timber in strength class C24, glued solid timber in strength class C24 and glued laminated timber in strength class GL24

“CUSTOM-MADE” DESIGN

Safe and cost-effective design

Prefabricated trussed rafter designs are created in our design office, where experienced and qualified staff makes sure that the best solutions for the roof are selected. The professional trussed rafter design is prepared in Dietrich’s programme, which allows a very high degree of pre-preparation of the structural elements.

Top-class carpentry

Prefabricated conventional trussed rafters combine all the advantages of carpenters’ craftsmanship with the advantages of prefabrication, i.e. precision and speed of timber processing.

Once all the elements of the trussed rafter have been cut to length, the corresponding carpentry joints are made and each element is numbered, which significantly optimises and facilitates the work and speeds up assembly on site.

All prefabricated trussed rafter elements are cut to size with great precision, enabled by the high-tech Hundegger K2i joinery centre. The state-of-the-art machinery makes it possible to achieve a first-class product, and the precision, durability and strength of the woodworking joints in the prefabricated structures is incomparable to that which can be achieved on the construction site. 

The produced trussed rafters are transported to the construction site as ready-to-assemble, numbered elements. This makes assembly considerably faster, optimising working time and saving money. 

We know a lot about the wood and woodworking

Conventional prefabricated trussed rafter - saving money, time and labour

  • optimal use of material
  • precision of woodworking joints impossible to achieve on site
  • diverse woodworking options
  • can be impregnated against fungi, mould and insects
  • clean, simple and quick assembly on site using the assembly diagram
  • lower investment cost, reduced construction time
  • design of prefabricated trussed rafter prepared by own design office
  • excellent aesthetics and durability of structure

In addition to aspects such as short completion time, accuracy and precision of the prepared elements, conventional prefabricated trussed rafter is also a product that perfectly meets the expectations of environmentally minded investors. Wood is a completely biodegradable material, while the production process itself leaves a much smaller carbon footprint than concrete.
