OSB 4 Heavy duty load bearing boards for humid conditions The thickness of OSB panels can range from 6mm to 25mm or more with thicker boards being used for heavier construction applications such as flooring and roofing One of the main reasons OSB is so widely used is its affordability The DIN EN 300 standard distinguishes four different OSB classes Of these classes 1 and 2 are not normally used in modern timber construction In Germany only classes 3 and 4 are available these are suitable for both humid and dry conditions Class 4 designates special heavy duty boards for loadbearing applications
OSB panels are available in a variety of thicknesses and sizes They are manufactured in both imperial and metric sizes and are either square edged or tongue and grooved on the long edges for panels 15 mm 19 32 or thicker The most common panel size is 1220 x 2440 mm 4 x 8 OSB weight is usually a bit more than its plywood counterpart For example 1 4 inch plywood weighs 0 8 pounds per square foot while OSB weighs 0 9 pounds for the same thickness Translated a 1 4 inch 4 x 8 foot plywood panel weighs 26 pounds while the equivalent size OSB panel is 29 pounds
