Sheathing Boards for a Range of Applications


Sheathing boards, according to one of many slightly varying dictionary definitions, are “boards of wood or fibre materials applied to the outer studs, joists, and rafters of a building to strengthen the structure and serve as a base for an exterior weatherproof layer.”

Steel Frame

Timber Frame

Sheathing boards are most commonly used as part of:

These three core applications cover a vast array of building types, meaning you will see sheathing boards used in almost every conceivable type of building, including:

  • Office Buildings
  • Schools
  • Hospitals
  • Libraries
  • Apartment Blocks
  • Industrial Premises
  • Retail Outlets
  • Leisure Centres
  • Agricultural Buildings
  • Sporting Arenas
  • Student Accommodation
  • Hotels

The most commonly used sheathing board products are plywood, oriented strand board (OSB), gypsum sheathing panels and fibre cement boards. Within each of these ‘sub groups’ there are numerous variations, with different facings, fibre types and, in the case of OSB, different grades of glue. No two sheathing boards are the same and there are, arguably, pros and cons for each. Sheathing boards are not required in all constructions, but they are where certain cladding or render systems are being used. Effective wall sheathing, correctly installed, renders a structure weather-tight, enabling internal trades to begin work in a dry, amenable environment. The speed with which sheathing boards can be installed, compared to other, more traditional building materials, is astonishing. The benefits of this speed of construction means buildings can be occupancy-ready to a surprisingly short schedule.
