Hirsipalkkeja

Hirsipalkkeja, the Finnish word for log timbers, refers to the primary building material in traditional Finnish wooden architecture. These are typically large, squared or round timbers hewn from logs, forming the structural walls of a building. The technique of using hirsipalkkeja has a long history, dating back centuries and playing a crucial role in the development of Finnish rural and urban landscapes.

The selection of wood is important, with pine and spruce being the most common choices due to their availability and durability. The logs are often seasoned before use to reduce moisture content and minimize subsequent shrinkage and warping. The traditional method of joining hirsipalkkeja involves interlocking corners, often using notches like saddle notches or dovetail notches, which create a strong and weather-resistant structure. This interlocking also provides a distinctive aesthetic.

The thickness and shape of the hirsipalkkeja could vary depending on the intended use and architectural style. Thicker logs offered better insulation, which was essential for the harsh Nordic climate. Over time, advancements in milling and construction techniques have led to more standardized and precisely cut logs, but the fundamental principle of using hirsipalkkeja for wall construction remains a significant part of Finnish heritage. Today, it continues to be used in both restoration projects and new builds, appreciated for its natural beauty, environmental friendliness, and excellent thermal properties.
