Frequently asked questions
Our technical team has gathered here some answers to questions that may arise regarding the properties and right use of WISA®-SpruceFR.
FR-treatment enhances the fire retardancy of plywood without any affect to strength properties.
Fire retardancy has been tested and classified according to European classification system.
Additional coatings are not recommended, because it might change the fire class. Compatibility of paint or varnish should be confirmed from paint/varnish manufacturer or supplier. Before painting/varnishing big areas, make first test with small sample.
Pressure impregnation process usually affect adversely to the strength properties of plywood. Panel properties after treating process are not the same as initially declared by panel manufacturer. Therefore, pressure impregnated panels can not be used for structural purposes without type testing of impregnated panels. In addition, wetting and drying of the plywood panels during pressure impregnation process likely causes deformations.
Fire retardant treatment of WISA-SpruceFR is non-toxic and does not contain halogenated compounds, heavy metals or boron.
Building Information Foundation RST has approved WISA-SpruceFR as belonging to emission class M1 for building materials. M1 stands for low emissions.
WISA-SpruceFR is developed for structural end-uses with high requirements for fire safety, e.g. public buildings.
WISA-SpruceFR is not recommended to be exposed to weather. Panel is primary designed for structural, not for visual, end-uses.
WISA-SpruceFR can be disposed the same way as untreated plywood panels. Always first consider reuse.
Panel has yellow tone and B-s1, d0 fire class indicated as part of CE-marking.
We are not obligated to make EPD’s by any legislation yet, and this is the reason we don’t have them available. Currently we are mapping service providers and different templates making/managing EPD’s, but haven’t made any decisions yet. Until that, we have the Environmental Profiles available for all product groups.
Plywood environmental profile is a declaration that gives basic environmental information on production of plywood. Plywood Safety Profiles are valid for all plywood products, separately for birch and spruce, coated and uncoated products. Plywood Safety Profiles include information on safe handling of plywood and a list of restricted substances in UPM. Plywood Safety Profiles have been developed to replace Material Safety Data Sheets (msds).
Both the Environmental declarations and safety profiles for spruce and birch plywood are available on www.wisaplywood.com. Those are valid for all plywood products, separately for birch and spruce, coated and uncoated products.
Finnish plywood mills and Otepää plywood mill in Estonia have both PEFC and FSC certified Chain of Custody system. Chudovo plywood mill in Russia have a FSC -certified Chain of Custody system. The sole wood supplier for UPM Plywood is UPM Wood Sourcing and Forestry, also having FSC- and PEFC certified CoC’s. These CoC’s guarantee that raw material is either from certified forests or legally and sustainably sourced and the origin of wood is known.
Forest certification is an excellent tool to promote sustainable forestry. It is based on standards drawn up during an open stakeholder process, implemented through forest management practices and verified by an independent third party. All wood supplies to UPM are covered by third-party-verified chains of custody.
Yes. All UPM plywood and veneer mills have ISO 14001 certified environmental management system.
UPM has Code of Conduct that defines the general responsible business principles that the entire personnel of UPM should follow. In addition, UPM Plywood has “UPM Plywood environmental rules”. These are the foundation for achieving environmental excellence in all our operations.
