Oriented Strand Board (OSB/3)

Write a review

OSB is a type of engineered wood board, with similar properties in durability and strength to MDF, MDP and plywood. Rated OSB/3 - load-bearing boards for use in humid conditions.

Certified FSC 100% – Formaldehyde Free 100%

Thickness:  9mm


OSB is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives.

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.

Common Uses

  • Wall construction and roof interiors. OSB panels can be used with all types of interior and exterior finishing materials
  • Manufacturing of I-joists – supporting floor and wall structures in timber houses
  • 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
