Strategic reserve of naturally dried and long-term aged timber

DREVO Air Reserve— a system of selection, slow natural drying, climate stabilization and long-term storage of valuable wood in a dry air environment.

The project complementsDREVO Timber Reserve, where wood is preserved in water, swamps and anaerobic reservoirs.

If DREVO Water Reservecreates stained and mineralized wood, thenDREVO Air Reservepreserves the natural structure, elasticity, acoustic properties, colour and stability of the dry material.

DREVO Air Reserve is wood whose value is formed not by water, but by time, air and proper aging.

1. Main goal

Create a strategic reserve of high-quality dry wood for:

architecture;

restoration;

construction;

furniture;

shipbuilding;

musical instruments;

artistic processing;

precision carpentry;

museum and cultural projects;

scientific research;

transmission to future generations.

2. Difference from a regular warehouse

A regular warehouse stores material until it is sold.

DREVO Air Reservemanages timber as long-term natural capital.

Each batch:

selected according to purpose;

dries according to an individual regime;

receives a digital passport;

is regularly examined;

stored in a stable microclimate;

can be maintained for decades;

reserved for specific future applications.

6. Main storage classes

ClassExposure periodPurpose
D-Air2–10 yearsExperimental drying of new species
C-Air10–30 yearsNext generation material
B-Air30–80 yearsStrategic reserve
A-Air80–200+ yearsTree Heritage

For some species, full stabilization may occur more quickly, but strategic status is determined not only by humidity, but by the length of documented aging.

7. DREVO Air Reserve Stages

Stage 1 - Selection

Evaluated:

breed;

age;

dimensions;

straightness;

knottiness;

cracks;

rot;

density;

structure of annual rings;

genetic and historical value;

future appointment.

Stage 2 - Primary Preparation

The following are being carried out:

cleaning;

sorting;

measurement;

metal detection;

end processing;

selection of debarking mode;

marking;

creation of a digital passport.

Stage 3 – Primary drying

It takes place under a canopy or in an open pavilion.

Target:

slowly remove free moisture;

avoid overheating;

prevent mold;

reduce the risk of cracks.

Stage 4 – controlled stabilization

The material is moved into a semi-open pavilion.

Controlled by:

temperature;

humidity;

air movement;

warping;

internal stresses.

Stage 5 – final drying

If necessary, apply:

soft convective drying;

dehumidification mode;

vacuum drying;

low temperature chamber;

solar-thermal drying.

High temperature conditions are not a basic requirement for valuable wood.

Stage 6 – Long-term exposure

The fully stabilized material is moved to a dry climate reserve.

8. DREVO Air-Drying Pavilion

The main object of the system is an adjustable semi-open pavilion.

Construction

high opaque roof;

wide overhangs;

protection from lateral precipitation;

adjustable blinds;

open top ventilation area;

raised floor;

drainage;

passages between stacks;

separate sections for breeds;

slow fans;

temperature and humidity sensors;

fire control system;

protection from birds and insects.

9. DREVO Climate Reserve Hall

After drying, the material is moved to a climate-stable storage facility.

Recommended parameters

ParameterOperating range
Temperature10–18 °C
Relative humidity50–65 %
Daily temperature fluctuationsMinimum
Daily humidity fluctuationsPreferably no more than 5-10%

LightingNo direct sun
CondensateNot allowed
PestsConstant monitoring

The main requirement is not the absolute value, butstability of conditions.

10. Correct stacking

Each stack must have:

separate basis;

identical gaskets;

vertically aligned rows of gaskets;

air access from all sides;

batch marking;

inspection passage;

top row protection;

deformation limiters;

the ability to safely remove individual elements.

Gaskets

Typically, the following thicknesses are used for gaskets:

20–30 mm for boards;

30–50 mm for thick workpieces;

individual supports for beams and logs.

11. Drying of round timber

Solid logs require a separate mode.

Key measures:

end protection;

partial debarking;

longitudinal compensation cut for some applications;

slow drying;

protection from direct sunlight;

long exposure;

regular measurement of cracks.

Large trunks with a diameter of more than 80 cm can stabilize for decades.

12. Drying boards and beams

Thin boards

Advantages:

rapid equalization of humidity;

lower risk of hidden dampness.

Risks:

warping;

drying out too quickly.

Thick boards and beams

Advantages:

high useful volume;

suitability for durable structures.

Risks:

internal cracks;

humidity gradient;

residual stresses;

long drying.

13. Musical wood

air humidity;

temperature;

wood moisture content;

development of cracks;

warping;

insect activity;

fungal infection;

condition of stacks;

fire risks;

climate history of each sector.

17. WOOD AI Wood

Artificial intelligence analyzes:

drying speed;

risk of cracking;

risk of mold;

optimal position of stacks;

transfer time between stages;

need for final drying;

prospects of use;

probability of transfer to a higher class;

suitable area of ​​application.

18. Pest control

Used:

quarantine of new batches;

visual inspections;

acoustic sensors;

traps;

temperature control;

local heat treatment;

freezing of individual batches;

anoxic treatment;

Permitted safe methods.

It is not recommended to use unless necessary:

toxic impregnations;

residual insecticides;

substances that impair future wood processing.

19. Fire safety

Dry wood is a strategic resource, but it is also a fire hazard.

Required:

division into fire sections;

fire walls;

wide aisles;

smoke and temperature detectors;

Automatic overheat detection;

lightning protection;

limitation of spark-generating work;

separate storage of flammable liquids;

fire water sources;

backup power supply;

Digital map of timber evacuation.

Particularly valuable lots should not be stored in the same building.

20. Territorial distribution

The reserve should not consist of one central warehouse, but of a network.

Network layers

national reserve;

regional reserves;

municipal pavilions;

forestry;

restoration centers;

university collections;

music and art funds.

This reduces the risk of losing all materials in the event of a fire, flood, conflict or technical accident.

21. Reserve rotation

DREVO Air Reserve should not be completely closed.

The rotation principle is applied:

new wood is classified as D-Air or C-Air;

inspected lots are transferred to B-Air;

the best units move to A-Air;

some of the mature wood is used;

new parties are being established in its place;

The entire history is stored in a digital system.

23. What not to do

The following is not allowed:

dry valuable wood in direct sunlight;

lay the material on the ground;

store in a sealed, damp building;

mix contaminated and clean batches;

accelerate drying without controlling internal stress;

overdry the wood;

allow for sudden climate changes;

store unique batches in one place;

The system creates a controlled stock of material that:

properly prepared;

slowly dried;

stabilized;

documented;

protected;

distributed across regions;

preserved for use through decades and centuries.

Together withDREVO Water Reserve, DREVO Timber Reserve, digital passports and the systemWOOD AI WoodThe project forms a full-fledged architecture of the wooden heritage for future generations.
