Plywood
General-purpose plywood with outer plies from SPF, sanded and unsanded, branded FSF, is produced at the Ilim Timber sawmill in Bratsk, according to GOST 3916.2.-2018.
Durable and resilient
In terms of flexural strength, Angara pine and Siberian larch are similar to or better than birch. Both species are also more resilient to external factors.
Moisture-resistant and environmentally safe
State-of-the-art waterproof, eco-friendly E1 adhesives and veneer layers of Siberian softwood ensure excellent resistance to moisture and environmental sustainability.
Distinctively unique texture
The outer plies of Siberian larch have a distinctive and unique texture. The Ilim Timber mill in Bratsk is the only large-scale manufacturer of plywood of this type.

Areas of application and grades
FSF softwood plywood with enhanced water-resistance and durability is suitable for a wide range of outdoor and indoor applications.
Plywood grades are assigned according to the visual surface quality which depends on natural wood properties of face veneer layers
1st grade
1st grade
1st grade (I/I, I/II, I/III) meets the most stringent requirements for visual appearance and strength properties and is best suited for furniture fronts as well as for interior and exterior design.
2nd grade
2nd grade
2nd grade (II/II, II/III) meets strict requirements for surface quality and strength properties and is best suited for a wide range of furniture and interior elements as well as for subfloors, underlayments and laminate cores.
3rd grade
3rd grade
3rd grade (III/III, III/IV) is used in construction, interior design and packaging as a durable, water-resistant material that doesn’t have to meet high requirements for surface appearance.
