The wood we use is Transylvanian spruce carefully chosen. This region with rigorous conditions gives it the quality of first class. This prodigious wood with tight and homogenous rings has an excellent mechanical and thermal resistance during a long period of time, and doesn't need much maintenance.
All woods with defects are eliminated (knots, sick wood and so on) directly in the sawing mill.
The moisture content of the wood before being launched into production is 16 +/- 2 %. (the wood is dried in the open and then in our driers).

Spruce has specific weight between 430 and 470 kg / m at 16% moisture, wich means 5 times less than concrete and 17 times less than steel. A two-storey house of 100 m on the ground, built of traditional materials (concrete, brick, etc.) weighs 200 tons, against 70 tons made of wooden structure. Wood strength in relation to its weight, makes it very attractive for slightly constructions. Wood cushioning shocks.
The wood is very resistant to compression and traction on his longitudinal sense and strength enough at transversal bending (especially the lamellar). But he did not break, he folds if the section of the piece subjected to bending isn't enough. At the compression, the buckling problem related with the flexibility of wood must be solved by a height-width ratio relatively small.
Compressive strength of wood is high - it must a load of 10 tonnes to crush a wooden cube with sides of 5 cm.

For the constructions, use the following types of wood:

  • Massive wood
  • Lamellar glued wood
  • Composite wood
  • OSB pannels

These elements are obtained from logs or elements with big dimensions.
The structural cuttings are pieces of wood having as main function, the resistance


Lamellar glued wood is obtained by longitudinal gluing, two or more lamellas of wood with uniform thickness and sections. This allows an increase in height and width of the wooden pieces. The adhesive is produced according to DIN EN 204 D4 group (highly water resistant). With this technique, pieces of wood are stable in time, dont crack or change their shape.


Composite wood is made ??of a thermally insulating lamella put between two other lamellas of wood. We use as insulator high density extruded polystyrene.


This panel consists of large strips oriented and joined together in an organic collage. The strips from the external layers are arranged parallel to the panel length. The strips in the inner layer can be oriented randomly or aligned, generally perpendicular to the direction of external strips.
The name OSB is Anglo-Saxon and means Oriented Strand Board.
The OSB panels are divided in:
OSB 1 - panel for general use in dry environment
OSB 2 panel used in dry environment
OSB 3 - panel used in damp environment
OSB 4 - panel used in very damp environment
