Is OSB Bad?! (Oriented Strand Board--What It's For / When To Use It...House Sheathing/Subfloor)
OSB is short for ORIENTED STRAND BOARD.
It first showed up in the 1970s, when the APA approved it as a multi-purpose construction panel.
OSB is typically used as sheathing for floors, roofs and walls in residential construction. Many builders turned to it in the 80s because of its low price point.
OSB is made up of small wood strands mixed with various waxes, resins and adhesives and pressed into mats and panels.
Despite its ugly appearance, OSB actually has better shear strength than plywood--this is, essentially, the property that prevents houses from collapsing sideways
If OSB has a serious weakness, it has always been with MOISTURE PENETRATION.
When OSB sits out in inclement weather, it absorbs moisture. This causes EDGE SWELLING--pronounced swelling at the edges.
Edge swelling can cause problems in construction if it pushes up shingles and thin flooring. This is known as "Expressing" or "Telegraphing."
OSB has a lot of competition in the market these days. The ZIP WALL SYSTEM is sort of like a house sheathing and house wrap in one, which is getting used a lot. And ADVANTECH is a very stable subfloor material that many builders prefer over OSB these days.
