🌲 The technological process - from log to finished sauna

Stage 1: Selection and preparation of raw materials (2-3 days)

Sources of raw materials :

• Only pine from certified Ukrainian forests (FSC/PEFC)
• Suppliers with a proven track record of responsible forest management

Control of incoming raw materials :

1. Visual inspection: no rot, large knots, or mechanical damage
2. Humidity measurement: tolerance ≤22% (hygrometer)
3. Geometrical check: straightness, no distortion
4. Sorting by diameter and length to optimize cutting

📊 Statistics : 8-12% of incoming raw materials are rejected – this is an investment in the quality of the final product.

Stage 2: Thermal modification – the heart of the technology (5–7 days)

Technological cycle in a thermal chamber :

1️ ⃣ Drying (24–36 hours)

• Gradually decrease humidity from 22% to 12%
• Temperature control: 60–80°C, humidity: 15–25%

2️ ⃣ Heating (12–18 hours)

• Temperature rise to 180–220°C in a superheated steam environment
• An oxygen-free environment prevents wood from burning.

3️ ⃣ Aging (6–12 hours)

• Temperature stabilization 215±5°C
• Decomposition of hemicellulose, crystallization of lignin

4️ ⃣ Cooling (12–24 hours)

• Gradually lower the temperature to 40–50°C
• Fixing humidity at a level of 3-5%

5️ ⃣ Conditioning (24 hours)

• Adaptation of wood to indoor conditions
• Final quality control

Thermal modification result:

Parameter	For processing	After processing (215°C)
Humidity	12–22%	3–5%
Hygroscopicity	10–15%	3–5%
Form	Prone to deformation	Stable (shrinkage <1%)
Biostability	3–4 grades	Class 1 (highest, EN 350)
Color	Light yellow	Deep chocolate (uniform)
Thermal conductivity	High	20-25% lower

🧪 Scientific confirmation : Research by VTT Technical Research Centre of Finland confirms that thermally modified timber of the Thermo-D class has rot resistance class 1 – the highest level according to the European standard EN 350.

Stage 3: Mechanical processing – accuracy up to a millimeter (3–5 days)

Workshop equipment :

• CNC milling centers (accuracy ±0.3 mm)
• Grinding lines with automatic grain size control
• Brushing machines for creating a textured surface
• Laser-guided cutting saws

Processing process :

1. Cutting to order dimensions (tolerance ±1 mm)
2. Milling of grooves, tenons, profiles for assembly.
3. Grinding: grit sequence 80→120→180→240
4. Brushing (optional): creating a relief texture
5. Sorting by color and texture
6. Marking: batch number, size, mounting side

💡 Expert advice : For commercial projects, we recommend brushing – it not only improves aesthetics but also masks minor scratches during use.

Stage 4: Assembly of modular saunas – control at every step (5–10 days)

Organization of the assembly line :

✅ Post 1: Frame

• Assembling a frame from pine timber 100×40 mm.
• Bioprotection treatment (water-soluble, odorless)
• Geometric control: tolerance ±2 mm at 3 m

✅ Post 2: Insulation and cladding

• Installation of 100 mm mineral wool + class A+ vapor barrier
• External cladding: vertical thermo-pine/rebated sheeting.
• Interior lining: horizontal thermo-pine, brushed.

✅ Post 3: Engineering Systems

• Electrical wiring (moisture-resistant cable, IP54)
• Installation of ventilation valves, traps, and drains.
• Installing fire protection around the stove (magnesite + SuperIsol)

✅ Post 4: Final compilation and testing

• Trial assembly of the module at the production facility
• Checking ventilation, electrical wiring, and drainage
• Photo and video recording for the client

📸 Transparency for the client : Each stage of assembly is documented – the client gets access to an online album with photos of their order.

Step 5: Packaging and shipping – protection on the way to the customer (1-2 days)

Professional packaging system :

1. Corner protection: cardboard corners + polyurethane foam
2. Individual sealing: each glass, doors, fittings
3. Five-layer cardboard: outer waterproof layer.
4. Stretch film: fixing components, protection from dust
5. Rigid sheathing: wooden slats around the perimeter
6. Marking: QR code, order number, installation side
7. Instructions, drawings, certificates, contacts

📦 Expert comment : For export to the EU, we add a QR code on the packaging - scanning it opens video installation instructions in English/German/Polish.

 

🔬 Quality control system - a guarantee of stability at every stage

Quality laboratory: equipment and methods

Instruments and equipment :

• Wood moisture meter (range 5–30%, accuracy ±0.5%)
• Geometry measuring device (laser rangefinder, protractor)
• Bending and compressive strength tester
• Camera for visual control of color and texture
• Thermal conductivity meter

Control methods :

Stage	Control parameter	Method	Admission
Raw materials	Humidity	Electric moisture meter	≤22%
After heat treatment	Humidity, color, geometry	Laboratory analysis	Humidity 3-5%, uniform color
Mechanical processing	Dimensions, surface roughness	CNC control, roughness meter	±0.5 mm, Ra ≤3.2 µm
Collection	Geometry of the module, tightness	Laser scanning, pressure test	±2 mm at 3 m, no gaps
Finished products	Electrical safety, water resistance	Insulation test, leakage test	Resistance ≥1 MOhm, no leaks

Certification and compliance with standards

International certificates :

Certificate	Standard	What confirms
FSC/PEFC	Responsible forest management	Wood sourced from legal, renewable sources
CE marking	EN 14915, EN 15816	Safety and electromagnetic compatibility conformity for the EU market
ISO 9001	Quality management system	Stability of processes, customer focus
