TAll our range of prefabricated buildings is made of first choice Norway fir-wood; each individual model is finished by hand in every minimum detail.
The models shown are obviously only a few of the infinite solutions that can be made, as it is also possible to use customized designs and plans.
The Technical Department of our company is at your complete disposal for studying and making special models and designs according to your specific requirements.
The consignment includes: complete works assembly, insulated roof structure according to the laws concerning energy saving, internal and external fir wood frames with insulating double glazing, painting of all visible parts with wood-protecting impregnating paint, transport of all the materials to the building site, wall perimeter insulation, roof surface, internal and external flooring.
Because of the special thermal seal of the construction elements, the living unit needs a very small number of Kcal/h. Our prefabricated buildings, on account of the characteristics described above, are to be considered firmly and robustly connected and strengthened in the joints, so as to make the weakening produced by this junction negligible and therefore they are suitable for first and second category seismic areas.
The base face on which the prefabricated building is constructed is generally composed of total bed foundations made of concrete.
Our CHALETS are built with fir-wood half-trunks with a thickness of 90 mm. The external face is rounded off (or smooth on both faces). Double facing on the support faces. Connection of the walls in the corners of the prefabricated building is made with a cross (see detailed plan) of notches and gains so as to avoid warping and make the structure more rigid.
The base structure is composed of a series of support squared timbers with a section of 10 x 5 cm, positioned with a centre-to-centre distance of 50 cm, on which the wooden flooring (with a thickness of 22 mm and duly anchored to these timbers) rests.
The internal dividers are made of fir-wood boarding with a thickness of 5 mm, inter-restrained with groove-and-tongue joints and connected to the external walls with dovetails, which thus contributes to the rigidity and stability of the prefabricated house.
The roof has, as a rule, a slant of 18° equal to approximately 32-33% (upon request it can be more or less slanting). It is composed of:
1. principal beam of the correct size in function of the loads, resting on the perimeter walls and the partitions and clamped to them with through screws of suitable size;
2. rafters are positioned at right angles to the beams described above with a centre-to-centre distance of 60/70 cm and dimensions of 90 x 120 mm (or other dimensions as from static calculations) duly anchored to the principal beams with through screws;
3. 13 mm-thick match-boarding made of fir-wood is nailed onto the rafters described above, tooth- and channel-assembled lengthwise;
4. an extensively joint-overlapped bituminized feltpaper is placed on the match-boarding above;
5. coarse fir-wood splines with a section of 10 x 5 cm are then placed and then tile-holding counter-splines with a section of 4 x 4 cm; the spline gap is finished with insulating felt made of rock wool with a thickness of 8 cm;
6. cement roofing-tile covering or other on the basis of the request.
The external frames are made of fir-wood with a thickness of 57 mm with insulating glass (air chamber) finished on the inside with blind- or shutter-type frames.
Balcony or porch railing with vertical or horizontal elements according to the building criteria of the "Case Dani" company.
Floors made of tapped fir-wood gibs with a thickness of 22 mm or of paving tiles.
The perimeter walls are also lined internally (after wooden splining and the insertion of an insulating pad with a thickness of 6 cm) with a fir-wood match-board with a thickness of 13 mm so as to have an external wall of 16.3 cm.
