OSB Frequently Asked Questions
 |
Are there any gaseous emissions from OSB? |
 |
A two-phase study demonstrated that formaldehyde emissions from OSB were at or below the lower limit of sensitivity of test methods, meaning formaldehyde emissions from OSB are negligible or nonexistent. These results were found in OSB manufacured by all SBA-member mills.
The test was co-commissioned by the SBA, along with the Composite Panel Association in the United States, and Forintek Canada Corporation. These findings support the blanket exemption given by HUD to manufacturers of phenol formaldehyde-bonded wood panel boards from the need to either test for formaldehyde emission or to attach consumer warning labels to the panels. Tests on OSB panels have also been proven to meet the requirements of the European and Japanese emission criteria. |
