Wood protection

FSC® or PEFC softwood from European forests is frequently used in gardens as fencing posts or for the construction of garden houses.


Our various preservation techniques, including thermal, chemical, and impregnation under pressure, are required to protect the timber and extend its lifespan.

Thermal treatment

ThermoWood® as an alternative to tropical hardwood

ThermoWood® is the result of a 100% natural and innovative process involving heating of the timber at high temperatures.

This treatment causes certain chemical changes in the timber, creating a hard-wearing and stable product that is resistant to insects and wood rot.

ThermoWood® is the hard-wearing alternative to hardwood and is frequently used for façade cladding or decking. ThermoWood® from LDCwood always has FSC®, PEFC, or OLB certification.

Immersion and impregnation

Improve your timber's lifespan

Our impregnation and immersion units (approved by ATG and CTB-B+) treat the timber with Wolmanit CX-10 so that it can be used in use classes 2, 3, and 4 (and 4SP) (NBN EN 335).


In this way, impregnated timber will have a longer lifespan so that it can be used for fencing, garden houses, garden screens, garden rooms, enclosures, borders, etc.

Coatings and brushing

Create a unique appearance

Our wooden facade cladding profiles can be supplied with a ready-made coating. We apply this coating in one or two layers on the most advanced industrial production lines.

Brushing brings the texture of the wood to life. It adds beautiful aesthetic value and ensures a more durable product.
