SMARTPLY FR OSB is a flame retardant structural OSB3 panel with European reaction to fire class C-s2,d0 and BFL –s1 performance. The panel also complies with the FR/FR Build performance requirements in accordance with STA’s (Structural Timber Association) “Design guide to separating distances during construction” for timber frame buildings above 600m² total floor area. Zeroignition Solution, a water based, eco-friendly, fire retardant is added during panel processing, ensuring fire performance whilst maintaining structural integrity. The addition of the ZI fire retardant during the manufacturing process ensures that the OSB3 panel quality is maintained to EN300 unlike post treatment fire retardant technologies which can have a destructive effect on the mechanical or physical properties of a panel.
SMARTPLY FLAME RETARDANT OSB3 panels are CE marked at the source of manufacture.
SMARTPLY FR OSB3 is manufactured in accordance with EN300 and EN 13986. It is the perfect choice for roofing, flooring and wall sheathing where strength, moisture resistance and flame retardance are paramount.
