Doing this before drying the strands eliminates excess energy use, and OSB plants usually keep a reserve of strands on hand in case a strander goes down for a knife change, so that the line can run continuously. Strand Together Under Pressure After tumbling through a dryer where temperatures may range from 1,500 F at the inlet to 200 F at the outlet, the strands are blended with a concoction of resins and waxes that varies by manufacturer, wood mix, time of year, and other factors. These OSB panels feature a thin sheet of aluminum laminated to LP OSB sheathing and include VaporVents, incisions that penetrate the radiant barrier, glue, and OSB substrate to allow the panels to dry quickly from construction moisture. OSB mills in the US and Canada are self sufficient in heat energy for both process and internal building heat. However, nail-holding ability controls performance in shear wall applications. Then it’s time to press: Mats are baked above 400 F and under pressure—which varies by board thickness, but is generally around 1,300 psi. Q: What is the curing process that takes place in the press?
