General information

General information

In our impregnation process, the wood and the wood product are wetted in their entirety and, depending on the product, 2-15% by weight of fire retardant is pushed deep into the cell structure of the wood, where it is fixed.

The combination of moisture and drying means that an initially finished planed, sawn or processed wood product can become slightly crooked and warped compared to untreated wood. The better the quality of the wood product, the better the final product.

In the fire impregnation process, the wood is soaked with water mixed with fire impregnation agent and then dried. The impregnation process also means that dimensional changes depending on the type of wood and plywood can occur, even within the framework of the same quality grading, which can result in the dimensions of the wood materials changing differently.

Dimensional change may deviate from planing tolerance and plywood tolerance, which is considered ok because the impregnation process takes place after planing and the production of plywood. It is the responsibility of the client/customer to take these conditions into account when ordering Woodsafe's contractor impregnation services through partners.
