Solid round log cabins are a specialty of ZRUBY RAJEC. We were the first to bring the know-how for producing these log cabins directly from Canada to Slovakia thirty years ago.

We have adapted the technology to local conditions and continuously seek ways to advance it in terms of construction, building standards, and design. This includes sophisticated W-grooves, new insulation materials, modern refinements, and more—all elements that have become well-established standards for us.

The majority of our over a thousand completed timber constructions consist of solid round log cabins. Our global presence and high production volume indicate that our company is a pioneer in this segment not only in Slovakia but throughout Central Europe.

High-quality material is a fundamental prerequisite for a quality construction. The wood we use is sourced from the high-mountain areas of the Malá and Veľká Fatra ranges, harvested at altitudes of at least 600 meters above sea level, from mature, non-calamity forests. It is very dense wood, with 5-7 growth rings per centimeter. These characteristics are similar to those of resonant wood used for musical instruments. This type of wood has a significantly lower lambda coefficient, which represents its thermal transmittance. Buildings constructed with such wood exhibit significantly better thermal insulation properties. Subsequently, suitable round logs are selected at the delivery site using forestry calipers.

The selected round logs are then transported to the company's handling depot, where they undergo a second visual inspection. Only pieces that meet the strictest quality criteria are chosen for the construction of the log cabin. Typically, this constitutes 50% of the timber that passed the first selection at the forest location.

The round logs selected for construction are immediately treated with a preservative spray to protect against pests. Additionally, the entire handling depot is equipped with pheromone traps for added protection. Round logs with a central diameter ranging from 270 to 500 mm are used for log cabin construction, depending on the specific purpose of the building and the climatic conditions of the construction site.
