All wood and production defects that do not have a significant impact on the strength properties of the plywood are allowed. Good bonding of all plywood layers is required.
In class IV, the plywood is not sanded and defects are not repaired.

Slow-burning EKO-FIRE plywood

Cross-structure birch veneer plywood impregnated with a flame retardant by the pressure-vacuum method. The plywood is non-flammable throughout its entire section. This allows for any processing of plywood while maintaining all non-flammable properties.

All ingredients of the flame retardant are of natural origin, therefore it is an environmentally safe and ecological agent. All layers are 1.5 mm thick. According to the guidelines, it can be used in public utility buildings. Specially designed and manufactured in accordance with the CE1 system for use in structural elements (walls and ceilings). Non-ignited plywood meeting the PN-EN 13501-1 + A1 standard is used in construction for walls and ceilings in the B-s1, d0 flammability class.

Species: birch 100%
Density: 660-740 kg / m3
Thicknesses available from 12 mm up
Technical class PN-En 636-2, Waterproof plywood based on phenol-formaldehyde resin (in accordance with PN-EN 636-2)
Flammability class according to PN-EN 13501 B-s1-d0

The classification is valid for: mechanical fastening on wooden battens or a substrate of metal structures, with horizontal or vertical connections with a ventilated or non-ventilated air void. The air gap at a distance of 40 mm from the standard A2-s1-d0 class sleeper according to PN-EN 13238: 2011.
