Kiln-Dried Lumber in Ukraine – Why It Matters and Why Choose Foreest
Moist wood is not suitable for use in construction or furniture manufacturing. That’s why kiln drying is used — a process that takes place in specially prepared drying chambers. This process produces kiln-dried lumber, which is stronger, more stable, and ready for use.
What is Wood Drying?
Wood drying is the process of removing water from timber. Moisture evaporates from inside the wood cells to the outer surface. Drying improves both the durability and appearance of the wood. There are two types of moisture content to consider:
-
Technical moisture – important for processing wood materials
-
Functional moisture – vital for construction purposes
Different moisture levels affect the usability of the wood:
-
Well-dried: up to 15%
-
Air-dried: 15–18%
-
Loading/moist stage: 20–25%
-
Wet: above 25%
Moisture content is crucial when choosing materials. High moisture wood is prone to damage, mold, and rot. For example:
-
Terrace boards, shutters, window frames: 10–15% moisture
-
Furniture, stairs, floors: 6–10% moisture
What is Kiln Drying?
Kiln drying is a controlled process of reducing moisture by placing the wood into a drying chamber. It ensures wood reaches the appropriate moisture level for its intended use — typically 10–12% for beams and strips.
Modern kilns are equipped with humidity sensors and automated systems that monitor:
-
Temperature
-
Air humidity
-
Airflow
This ensures even drying and minimizes the risk of cracks, warping, or deformation.
Advantages of Kiln Drying
-
Faster processing time compared to natural outdoor drying
-
Eliminates pests and fungi through high-temperature exposure
-
Preserves wood structure and color for high-end products like trim and moldings
-
Improves production efficiency by reducing waste and increasing precision
-
Long-term savings – an investment that improves quality and profitability
-
Dimensional stability – ensures accurate sizing for planing and machining
-
Weather protection – wood is protected from rain, snow, and wind during the process
Kiln-Dried Softwood Lumber in Ukraine
Despite its density, softwood lumber is easy to work with when dried correctly. Proper kiln drying greatly enhances durability and resistance to pests, fungi, and cracking.
Our drying chambers reach up to 60°C, controlled by advanced computer systems. The drying time depends on wood thickness and initial moisture content. After drying, our lumber reaches around 20% core moisture, making it sterilized and low-risk for decay — often eliminating the need for additional treatments.
Structural Grading of Lumber – C24 and Above
Lumber classification is based on strength and durability, graded visually or mechanically according to DIN 4074-1 and EN 338 standards. For example, C24 grade has:
-
Bending strength: 24 N/mm²
-
Tensile strength (longitudinal): 14 N/mm²
-
Compressive strength: 21 N/mm²
-
Average density: 420 kg/m³
Defects that disqualify lumber from structural use:
-
Excessive cracking
-
Knot clusters
-
Warping and curvature
-
Presence of rot
-
Insect bore holes
Lumber is graded after drying, which is why raw lumber from sawmills often remains unclassified.
