Pressure treatment

Smaller sized items like furniture, fence panels (in addition to painting), flower boxes, and other products can be pressure treated in the vacuum-pressure-vacuum method giving these items a green, brown or grey shade. In order to extend the service life of timber we treat our products with Impralit®-KDS (HC3, HC4) and Embalit (HC3) wood preservatives.

This is a water-borne, chromium free wood preservative for the prevention of insect attacks, soft rot and fungal decay. It also offers temporary protection against blue stain and mould. Impralit®-KDS is only to be used for treating wood according to the requirements of use classes 1, 2, 3 and 4 as stipulated in EN 335-1. For wood under cover and in the open, above ground and in ground contact, e.g. poles, fencing, playgrounds, pergolas, etc. 

The preservative penetrates deep into the wood with the help of vacuum and pressure. In this case a vacuum is initially generated in the cell cavities thereby evacuating the air inside them. The cavities are then filled with a preservative solution that is forced into the wood under high pressure. For vacuum pressure impregnation we work with different processes depending on the type of wood, environment and end purpose.

Green or brown impregnated products have been treated with Impralit®-KDS wood preservative from Rütgers Organics GmbH. It is a water-borne, chromium free wood preservative for the prevention of attack by insects, soft rot and fungal decay. It also offers temporary protection against blue stain and mould. Embalit P/Embacolor CG by Hoetmer b.v. is a grey coloured wood preservative system based on the active propiconazole. Wood treated with this is free of heavy metals and can be used in hazard class 3. It protects the wood from decaying and preserves the wood for many years.
