The plywood sheets are safe in terms of health protection and are classified in the Formaldehyde Release Class A to ČSN EN 1084, corresponding to the E1 emission class (Formaldehyde Release Class) according to the method of gas analysis; Anti-slip BEECH plywood sheets are waterproof plywood sheets made of broadleaved and coniferous wood species surface treated with phenolic foils to PN 003–49–01.

Variants

• “Combi” (beech-kombi (beech – alternate plies of beech and spruce – beech)
• “Twin” (beech-softwoods-beech)

Side edges are provided with a waterproofing coat. Bonding quality shall comply with the requirements of Bonding Class 3 to ČSN EN 314–2 (EW 100).
