Top Tips For Your Oriented Strand Board

Oriented Strand Board (OSB) is a form of manufactured wood, just like particleboard. Compressing several layers of wood strands and adhesives in specific ratios form OSB. The material has a variegated and rough surface where the individual strips lie across each other unevenly, creating a variety of thicknesses and types.

Uses of Oriented Strand Board

OSB boardSince its invention, OSB has been used as an alternative to plywood. It has favourable mechanical properties, making it suitable for use in construction. Some of the applications include:

  • Sheathing in walls
  • Decking the roof
  • Making floors
  • It may also be used in furniture production.

Types of Oriented Strand Board

OSB may be classified into five grades based on their physical performance and ability to resist moisture. Here are the different grades:

  • OSB/0 – Does not have formaldehyde and is mostly referred to as the “New-generation” OSB
  • OSB/1 – Mostly used for interior fitments or general purposes and is, therefore, likely to be used in dry conditions
  • OSB/2 – Mostly used in dry environments
  • OSB/3 – A load-bearing board which is mostly used in humid conditions
  • OSB/4 – Mostly used in moist environments because it is a heavy-duty and load-bearing board

Client Instructions and Tips for using Oriented Strand Board

  • Make sure that the writing on the panel is at right angles since OSB panels have different strengths depending on the direction as a result of the three layers.
  • Use the correct thickness of the OSB board according to the use at hand. Standard dimensions include a diameter of 11 mm for roofing, 9 mm for sheathing walls and 18 mm for floors.
  • Use a minimum bearing distance of 18 mm to prevent the ends of the boards from getting snapped off.
  • Support the edges with studs or joists to prevent relative movement of the boards.
  • Use ring shank nails to ensure a good grip on the board since shank nails are better than plain nails.
  • Space the fixings depending on the board thickness and whether it is around the edge or is an internal fixing.
  • Use a minimum of 8 mm distance to nail a panel to lower the chances of the nail pulling out and increasing effectiveness.
  • It is advisable to glue joints before nailing them, therefore, giving the board a finished look.
