Plywood is a construction material manufactured from firmly glued layers of wood (peeled
veneer) with cross structure (special kinds of plywood meant for higher resistance to bending
and warpage).
Plywood is very strong and water-resistant due to the usage of synthetic resins for veneer gluing.
Exterior birch plywood is the product of heightened water resistance due to being glued with
usage of phenol-formaldehyde resin. Except heightened water resistance our plywood has such
properties as high strength, durability, ease in further processing, beautiful texture of birch wood,
light weight, high performance properties. It’s Exterior birch plywood that one chooses facing the
hardest conditions of usage.
Plywood is subdivided into grades depending on surface appearance of face veneer. The grade of
plywood is the combination of grades of two face layers of veneer.
Depending on surface treatment, plywood is either with both sides sanded (S2) or not-sanded
(NS).
Nonstandard thicknesses and sizes are possible to produce on enquiry and agreement with the
clients.
