Frequently asked questions about the Lumber and wood-based panels category
Lumber and wood-based panels — what are they and where are they used?
Lumber and wood-based panels are construction materials including beams, planks, lining, plywood and OSB boards. They are used in building and renovation for structural timber, flooring, wall and ceiling paneling, terraces and furniture.
What types of plywood are available and how to choose for floor or walls?
Available plywood includes regular plywood and grades like EXT pine C+/C and F/F birch I/II, plus Detail plywood in 6×760×1525, 6×507×507 and 6×380×380 sizes. For flooring choose moisture-resistant plywood 18–21 mm thick; for walls 6–12 mm is usually sufficient depending on load.
How do thermo-treated lavalaud (TERMOHAAB) differ from regular planks?
Thermo-treated lavalaud such as TERMOHAAB 28×90×2700 or 28×90×1800 are heat-treated to lower moisture content, increase dimensional stability and decay resistance. Regular planks retain natural wood properties and typically need extra protection for outdoor use.
What sizes and types of terrace boards are available?
Available terrace boards include impregnated sizes 28×120×4500 mm, 28×95×4500 mm, 28×120×3300 mm and WPC composite 25×140×2700 mm. Options come in brown and green shades and composite WPC for low maintenance.
What construction timber is available: beams, boards, rafters?
The category includes construction timber such as beams (e.g. 50×200×6000), planed boards (e.g. 18×45×2700) and various rafters. Select cross-section and length based on your structural load requirements.
What is vooder/lining in this collection and what sizes are available?
Vooder/lining is decorative boarding for interior wall and ceiling finishes; the catalogue includes items like VOODER TERMOHAAB 15×90×2700. Choose profile, wood species and length to suit your installation.
What OSB and wood-fibre boards are offered and what are they suitable for?
The range includes OSB boards and soft wood-fibre boards suitable for sheathing, subfloors and sound insulation. OSB is good for structural and flooring use; fibreboards are suitable for interior finishes and furniture components.
Which plywood size is better for making furniture: 6×760×1525 or 18×1250×2500?
For furniture, 18×1250×2500 (F/F birch I/II) is preferred because it is stronger and reduces joints. 6×760×1525 sheets are useful for smaller decorative parts and fronts.
Which lumber is suitable for outdoor terraces and what treatments are recommended?
Suitable options for terraces are terrace boards, thermo-treated TERMOHAAB, impregnated boards and WPC composite. Recommended treatments include antiseptic impregnation, decking oil or varnish and installation with ventilation gaps.
