Base board
Plywood made solely from pine (softwood) veneers bonded together in a cross banded construction.

Bonding
Phenolic resin cross-bonded weather resistant glueing according to EN 314-2/ class 3 exterior, EN636-3.

Surface
Film of 125 gr/m² both sides, brown color

Edge protection
Two coats of water resistant paint.

Thicknesses and weight

Nominal thickness (mm) Min. thickness (mm) Max. thickness (mm) Weight (kg/m²) n° of layers
18 17,8 18,2 9,81 11
21 20,8 21,2 11,45 13

Panel size
2440x1220 mm or 2500x1250 mm

Size tolerances
± 1 mm - The panel can have dimensional changes due to changes in the air humidity.

End uses
Usage mainly for slab forms. Typical number of reuses is likely to be about 5 -10 times. However the number of reuses will depend on a wide range of factors including good site practice, the required con-crete finish, careful handling & storage of forms and the type and quality of release agent.
