quality
Quality classification refers to standards EN 635-2
GIOCONDA :
- CLASS II (former class B of UNI 6471)
- CLASS III (former class BB of UNI 6471)
-
- CLASS I (former class AB of UNI 6471) Faces that may remain visible, ideal for any type of finishing (coatings, transparent varnishes, satin-finished etc) May also contain a few pin knots or healthy and adhering knots without cracks. May also include very light discolorations and small, well-done putty or repair work that blends in with the rest of the surface.
-
- CLASS III (former class BB of UNI 6471)“Open” face, putty work upon request, ideal for non visible usesMay contain healthy, adhering knots of diameter up to 50mm, small non adhering knots, cracks, bark, overlapping. May include natural discolorations, glue stains, repairs and any kind of putty work.
gluing
The gluing is consonant with the norm UNI EN 314 and it is determined only on the basis of its resistance to the humidity that defines the gluing class (norm UNI EN 636)
The Invernizzi poplar plywood TWIN CEIBA is produced in:
- CLASS 1: ureic gluing suitable to panels used in dry places and in interiors (UNI EN 636-1)
- CLASS 2: melamine gluing suitable to panels used in damp or in outside but sheltered places (UNI EN 636-1). All Invernizzi plywood panels are in formaldehyde emission class EI (Certificate CATAS);
- CARB PHASE 2: special gluing on demand consonant to the Californian norm demanding absolutly the lowest formaldehyde emissions.

Technical features report indicative average values of poplar plywood, urea based glue line, referring to an average wood moisture content of 10% +/- 2%, realized using wood from the I-214 clone. These values may vary if, though keeping the same relation between thickness and number of layers, a different clone is used or in case there is a variation in the panel's core composition (way the veneers are disposed, thickness of the various layers).
