Silvaprodukts test field at companies headquarters.

We are conducting two facade tests at the moment at our company’s headquarters, one positioned on the south and the other on the west side of the building. In this way we better capture and observe the conditions the facades (wood) face in reality.

Silvaprodukt Company, in close cooperation with Biotechnical University and experts from Department of wood Science and Technology, is conducting ongoing tests of many different wood samples on field at the Universities headquarters.
After 10 years – beams are decomposing, while some of our impregnated samples remain perfectly healthy. 

The first type of samples shows the inadequacy of commercial oils for outdoor wood protection.

Many samples that failed are being examined in laboratories. During years long testing we also had to cut down few higher self-planted trees.
