Here you will find general information about plywood and its characteristics. All plywood properties can be found from the Handbook of Finnish Plywood.
The moisture content of WISA plywood at the mill is between 7-12% and it varies according to the conditions. The moisture content has an effect on the plywood sizes.
Changes in the temperature (+100 C - -160 C) do not affect the plywood sizes.
USE IN EXTERIOR CONDITIONS
In exterior conditions, plywood must be properly surfaced and edges sealed.
The strength properties of plywood are dependent on the wood species, the thickness of veneers and plywood, and grain direction. The surface veneer quality does not affect the strength properties.
