They have an ideal shape and accurate size.

Baths made of galled logs have the greatest thermal insulation, since the production technology used in the processing of logs allows you to make the diameter of the logs the same along its entire length. Due to this, when laying galled logs, the greatest fit density is achieved to each other. Escilled logs can also be connected at any angle. They have an ideal shape and accurate size. Therefore, such baths have excellent thermal insulation properties.
