"TUTTOPioppo"
INVERNIZZI’s poplar plywood is a natural product manufactured using poplar veneers (at least 3 plies), which have been overlaid with the wood grains running perpendicularily and glued. It is manufactured according to the formaldehyde emission control rules and can be proposed also provided of FSC or PEFC, E1 or CARB Phase 2, CE or CE+ certificates. The main feautures of the panels are: light color, low weight, uniform faces and cores and good technical performances. The product is manufactured in the maximum respect for the environment with the most limited use of chemical additives.
F-4 stars compliance
PLYWOOD
Upon request, Invernizzi s.p.a. poplar plywood panels meet the requirements of the QUALITY AWARD FORMALDEHYDE 4 STARS technical regulation on low formaldehyde emissions, assessed by the CATAS Laboratory abiding by the JIS A 1460 standard (Desiccator method). This Standard is used in Japan to determine the quantity of formaldehyde emissions in construction panels. Since Invernizzi plywood panels showed emissions levels lower than 0,3 mg/l, they can be classified as F****, which represents the most severe level imposed by the classification system provided by Japan Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

GIOCONDA :
- CLASS I (former class AB of UNI 6471)
- CLASS II (former class B of UNI 6471)
- CLASS III (former class BB of UNI 6471)
- CLASS IV (former class C of UNI 6471)
-
- CLASS II (former class B of UNI 6471)“Natural” face with colour variations and healthy knots, suitable for coating with laminates, colour paints or varnishesMay contain healthy, adhering knots of diameter up to 35mm, small fallen knots or cracks, as long as good putty work has been done. May also include discoloration that is not very contrasting, some glue stains here and there, good repair and putty work.
-
- 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.
-
- CLASS IV (former class C of UNI 6471) Plywood face designed for packaging and similar uses May contain all the natural wood characteristics and the various processing defects, provided these do not compromise the functions of the plywood (e.g. the presence of fungus or iron parts is not allowed).
-
- 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.

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 plywood 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).
