OSB Frequently Asked Questions

What is OSB's fire performance? |
 |
Independent studies conducted to obtain flame-spread ratings in OSB found that uncoated panels made by SBA member mills meet or exceed the minimum flame-spread requirements of The National Building Code of Canada.
Other tests were conducted by Forintek Canada Corporation, a major independent Canadian research firm. The tests used OSB panels coated with latex interior paint and two fire-retardant paints, which improved their flame spread ratings. The model building codes also recognize the equivalent performance of OSB and plywood panels in many wall or floor assemblies requiring a minimum fire rating. |
