conveyer method and updated controls mean that OSB is now available in a broader range of thicknesses, widths and lengths than physically possible with the ‘Daylight Press’ technique.
This means OSB can now reach much wider spans, making it ideal for use in timber joist, roof or structural applications where there is no longer a restriction on length. Teamed with the strength of OSB, and technical variants including flame retardant and moisture resistant panels, these extended sizes allow a huge amount of design flexibility.

Specialist OSB panels are now available that are not only structural but airtight and vapour tight too
Where do we go from here?
With fully certified raw material, new manufacturing methods and a whole host of new opportunities, what is next for OSB? Some would say ‘the sky’s the limit’, with longer and wider structural panels allowing the construction of larger, taller, more complex buildings. But sky may not be the next new arena for OSB – air may be. With the growing trend towards low energy or Passivhaus constructions, OSB must look to the future and innovate to stay relevant. For many years, people have
assumed that OSB is airtight, however, contrary to popular belief, standard OSB (or any standard wood panel) is not suitable for use as an air and vapour tight layer. This issue has been the subject of much scientific research in order to evaluate the air permeability of OSB panels and to provide limits to manufacturers and end users.
Further to the results of this research and a great deal of development, specialist OSB panels are now available that are not only structural but airtight and vapour tight too, perfect for use in Passivhaus or Low Energy construction. The smooth finish provided by the ‘Conti-Roll’ manufacture even assists here, where the smooth surface provides ever improved adherence for jointing and sealing tapes.
OSB has moved a long way from its old roots as an emergency hoarding panel and now sits at the top table with the most sustainable, innovative and flexible products on the planet, and they don’t cost the earth either.
