“LATH” (4) T&G 20mm

• AB Grade - Good Visual Quality

Knots: Allowed and mostly sound (black knots up to 15 mm).

Cracks: Small cracks along the grain are permissible. On the visible side of the board, cracks up to 10 cm are allowed; on the reverse side, cracks may extend up to 25% of the board length. Cracks must not penetrate through the board.

Resin pockets: Small resin pockets (up to 50 mm) are acceptable.

Colour: Slight variations in shade are acceptable.

Bruising: Minimal and only local.

Defects: Rot and insect damage are not permitted. Through-cracks are allowed only at the ends of the board and must not exceed the width of the board.

• BC Grade - Medium Quality Material

Knots: Larger knots are allowed and unlimited in number; some may be loose or missing.

Cracks: Cracks along the grain are permissible (up to 30% of the total board length), as well as through-cracks up to 1 m.

Resin pockets: Acceptable.

Colour: Uneven colour tones are acceptable.

Bruising: Permitted to a greater extent.

Defects: Loose or missing knots, breaks, and mechanical damage are permissible. Small knots affected by rot or insect damage are also allowed.

The most suitable planing option can be selected depending on the intended application.

A smoothly planed surface is particularly suitable for transparent finishes and stains that highlight the natural wood texture.

A finely brushed surface is suitable for opaque paints where good adhesion to the material is important.

Spruce: Spruce wood is softer, lighter in colour, and has more pronounced fine knots.

Pine: Pine wood is denser, with a more distinctive grain pattern and higher resin content, making it more resistant to moisture.

We offer high-quality wood processing and treatment services for both companies and private customers.

Industrial wood coating - an industrial process using automated equipment that ensures an even and durable coating, protection against external factors, and a long-lasting aesthetic appearance for façades, terraces, fences, and interior finishes.

Brushing (aging effect) - a process in which a brush removes the softer wood fibres from the surface, giving the material an antique, textured appearance that creates a modern and cosy atmosphere in interiors.

Wood charring - a treatment process using flame and oil finishing that gives the surface a unique appearance, additional durability, and hardness, making it suitable for both interior and exterior use.

Thermal modification - a wood treatment method using high temperature and steam without chemicals, improving resistance to moisture, biological decay, and deformation while also reducing thermal conductivity.

Fire-retardant treatment - wood treatment with special agents that reduce flammability and increase fire resistance, making the material suitable for construction and interior applications where fire safety is particularly important.

Impregnation - the wood is treated with special preservatives that protect it from damage and extend its service life, making it particularly suitable for construction, outdoor furniture, and fencing.
