Accelerate the process of preparing material for the construction and installation of any buildings allow new technologies in the construction of houses. New technologys allows to build with better quality, safety and economically more effective houses, saunas and other wooden facilities. All main elements of the house are made in own manufactury site, which allows to organize manufacturing of wood processing from the raw log to finished product. Technological lines are equipped with modern woodworking machines, high quality of the product is achieved.
Using of new technologies and modern specialized computer-aided design programs allows to connect all phases of the production process (from the premilinary draft to the assembly of the house kit) and are carried out according to the technical documentation.
Seeking of an effective solution using new technologies in the construction of houses, the company's specialists developed a new constructive and energy-saving timber element - insulated timber.
This wall element in it’s form is not different from the traditional monolithic or glued timber. Structurally it is a frame, filled inside with polyurethane foam (FPU).
For the production of insulated profiled timber, a winter wood of a certain diameter is harvested and sorted, than the workpieces of the required size are formed. These workpieces of the standard cross-section are drying until the humidity value is reached in the range of 10-12%.
After the workpieces have dried, they are processed with the highest precision on special machines, where they are converted into semifinished products of lamellas and inserts of specified sizes. It should be noted that semifinished products of lamellas can be made from monolithic, and from glued parts.
The frame of the timber is composed from two wooden lamellas with wooden inserts along the entire length of the frame. The inserts are mechanically fixed between the lamellas by a strong connection (through bulkhead “dovetail”). After that, the semifinished product comes into the pouring area. The space of the frame between the lamellas is filled with polyurethane foam. Filling is carried out automatically on a special machine line.
Polyurethane foam is a ready liquid mixture, supplied as a two-component system with extremely high adhesion, including with wood structures. The thickness of its layer is determined on the basis of heat engineering calculation. In particular, for the climate of the countries of the Baltic region, the thickness of the FPU layer is 70 mm. The material does not contain ozone-hazardous chlorofluorocarbon blowing agents; complies with the flammability requirements. It has a high chemical resistance, is not rotted and is not friendly to rodents and environmentally safe material.
After that, the workpiece of the insulated timber is processed to profiling on four-sided machine tools. As result- joints are combined absolutely densely and moisture does not penetrate into them, they are not blown and do not freeze. After profilling timber is cut to the required size with high precision. The last operation - "cutting" the grooves on special machines and drilling holes for screed.
