Oriented strand board, also known as OSB or OSB Board, is an engineered wood product formed by layering strands (flakes) of wood in specific orientations. Similar if not superior properties to MDF (Medium Density Fiberboard), MDP (Medium Density Particleboard) and other particle boards.

It is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives (95% wood, 5% wax and resin).

Each layer is laid perpendicular to the previous in order to maximise the strength of the finished product. Once the desired thickness has been achieved, the strands are heated and pressed together to result in a board that is strong, thin, durable and flexible.

The mat is placed in a thermal press to compress the flakes and bond them by heat activation and curing of the resin that has been coated on the flakes. Individual panels are then cut from the mats into finished sizes

When made from timber scraps or recycled wood, OSB is more environmentally friendly than plywood. Even when made from harvested timber, OSB tends to be the more environmentally friendly option. This is due to the small strips of wood it requires; young, fast growing timbers can be used, including pine and even bamboo.

General usage of OSB:

  • Used as part of wall construction and roof interiors. OSB panels can be used with all types of interior and exterior finishing materials.
  • In manufacturing of I-joists – supporting floor and wall structures in timber houses.
  • In manufacturing of Structural Insulated Panel Systems (SIPS) consisting of two outer OSB layers and a core polystyrene foam layer.
  • Removable formwork for concrete works (multi-use formwork). Sanded and overlayed OSB panels can be used repeatedly as a concrete formwork.
  • Furniture –frames of upholstered furniture, chairs, cabinet furniture, home built-in furniture (coat closets, shelving units, wall wardrobes).
  • Temporary construction site fencing, coverings for structural openings (windows, doors).
  • Shipping crates and pallets, shelving units, exhibition stands, furniture shelves, shop counters, table tops, bill boards
  • As a structural bracing panel.

General features of OSB:

  • High bending strength, high elasticity
  • Smooth and solid surface
  • Resistance to damage and deformation in service conditions (warping, checking, delamination)
  • Good vapor permeability and air-tightness
  • Easy cutting, processing and usage
  • High fasteners withdrawal resistance
  • High sound insulation (sound absorption) performance
  • High abrasion resistance
  • Uniform structure
  • Easy transportation
  • Suitable for humid conditions
  • Uncoated / Untreated / Unsanded – because of decorative surfaces, boards are often left exposed
