Frequently asked questions about the OSB boards category
OSB boards — what are they and what are they used for?
OSB boards are oriented strand boards made from arranged wood strands bonded with moisture-resistant resins; used for subfloors, wall sheathing, battens and light structural elements. Common sizes include 2500x1250 mm and narrow detail panels (625 or 300 mm) with thicknesses from 6 to 25 mm.
What standard sizes and thicknesses of OSB boards are available?
Most boards are 2500x1250 mm, with detail panels 625x1250 mm and 300x1250 mm also offered. Thicknesses range from 6 to 25 mm — 6–10 mm for cladding, 12–22 mm for floor and structural use.
Are OSB boards suitable for floors and which to choose?
For floors, 18–22 mm boards are commonly used for subfloors, with 12 mm only on very sturdy supports; choose moisture-resistant grades and fit boards on a level joist system allowing expansion gaps. The catalogue includes 18 mm and 22 mm boards in 2500x1250 mm.
OSB boards on a wooden floor: best installation method?
Fit boards onto joists with corrosion-resistant screws, leave 2–3 mm expansion gaps between panels and size joist spacing to board thickness. Seal or treat edges and use a moisture-resistant grade for added protection.
Are OSB boards harmful to health?
OSB uses resin binders, so choose low-formaldehyde emission grades for indoor use; with normal ventilation and correct installation the risk is low. Check the board’s emission class when using in living spaces.
What is the difference between OSB PANEL and OSB DETAIL in the range?
OSB PANEL are standard full-size boards 2500x1250 mm in various thicknesses; OSB DETAIL are narrow or cut pieces (625x1250, 300x1250 mm) for finishing and joinery. Use panels for large coverings and details for precise fitting tasks.
What characteristics matter when choosing OSB for exterior use?
For exterior use choose moisture-resistant grades, sufficient thickness (12–22 mm), and sealed edges; ensure the board’s adhesive and density suit exposure. Provide ventilation gaps and protective finishes during installation.
OSB board sizes: what lengths and widths are available?
Most boards are 2500x1250 mm; detail pieces are offered in 625x1250 mm and 300x1250 mm. Some items use markings like p.serv2,5x0,625 — always check the product page for exact dimensions.
What thickness of OSB is needed for wall sheathing and partitions?
For wall sheathing and light partitions use 9–12 mm boards; 12–15 mm increases stiffness for higher demands. For load-bearing elements select thicker boards per design requirements.
What joist spacing should be used when laying OSB 12 mm and 18 mm?
For 12 mm OSB joist spacing is typically 400–600 mm depending on load; for 18 mm OSB spacing up to 600–800 mm is common. Exact spacing depends on project load requirements.
