Oak lumber is the main raw material of the wood industry, it is used for the production of floor panels, furniture and decorative elements. Oak lumber is used in the carpentry, construction and woodworking industries as well as in the paper industry. The lumber should have suitable technical parameters depending on the use of the material. Hard oak wood is especially suitable for various carpentry, furniture and floor work. Soft coniferous wood is used for roof structures, windows, doors, but also boards and floors.

How to store oak lumber

Proper storage of lumber is a very important issue. Improperly stored oak lumber may be damaged and deformed and may not be suitable for further use. Timber should be stored in piles, i.e. boards twenty-five millimetres thick in the fresh air or in a specially designed room. The stack should be set on support or concrete poles to prevent the wood from getting wet. Only chimneys have favourable conditions for drying and preserving lumber.
