KEY FACTORS ASSESSED
Strength — the products have adequate strength to resist the loads associated with the installation of the roof.
Liquid water penetration — the products resist the passage of moisture into the building.
Durability — under normal service conditions the products will provide a durable covering with a service life of in excess
of 20 years.
Biological attack — typically OSB will not be attacked by wood-boring insects common in temperate climates. It can be
used in hazard classes 1, 2 and 3 as defined in EN 335-1.
2
Thermal conductivity — The thermal conductivity of OSB is 0.13 W/m.K for a mean density of 650 kg/m .
Reaction to fire — Under the new Euroclass system for the reaction to fire of materials, untreated OSB with a density
2
>600 kg/m and a thickness >10 mm will typically achieve a Euroclass D rating.
