OSB vs Plywood comparison. While OSB (Oriented Strand Board) is generally cheaper than plywood, it is heavier and not as stiff as plywood and can result in soft squeaky floors under weight.
Plywood panels give floors, walls and roofs substantial shear strength to counter wind and other horizontal forces such as earthquakes. By orienting the grain in two directions you create a much stronger “panel”.
APA Resource Library. APA offers an extensive collection of detailed, technical information for architects, builders, code officials, engineers, specifiers, and others in the trade.
Building codes consider OSB (Oriented Strand Board) and plywood interchangeable and refer to both as “structural wood panels” as both OSB and plywood panels are created when wood is glued and compressed to form a rigid panel.
We offer the largest selection of plywood and composite panels in Central New York, including wood shipped from across the United States as well as internationally.
DryPly® plywood sub-floor panels have a water-repellent coating to provide weather protection during the normal exposed construction cycle. Plytanium® Plywood Siding Plytanium® plywood exterior siding is an all-plywood, exterior-grade panel ideal for siding applications from new home construction, remodeling and DIY projects.
Innova manufactures plywood SIP panels 4’ wide in lengths up to 24’ and these panels can be used for floors, walls and roof panels. We manufacture these panels with ½” CDX plywood, ¾” pressure treated plywood or other plywood material as specified by the client.
OSB panels can be found in lengths up to 16 feet, whereas plywood is limited to 8 to 10 feet. For larger projects, builders and contractors feel that OSB is a better choice because it boasts more consistent density.
Plywood is a sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another.
My personal opinion is that OSB performs well on the wall and floor but stick to CDX Plywood on the roof. Far too often I see OSB “sag” between the trusses making your roof look wavy. Although, OSB typically offers a higher shear rating which adds rigidity to your structure.

for floors (36) for roofs (4. MIACORE™ is an ultra-light composite panel made with aluminum honeycomb core lined with epoxy glass fiber skins or aluminum skins.
Both OSB and plywood panels can be used for wall sheathing, sub-flooring panels and roof panels, but OSB has some advantages Plywood composite panels for floors and roofs : summary. Get this from a library!
Includes information on plywood and oriented strand board (wood structural panels), glulam, I-joists, structural composite lumber, typical specifications, and design recommendations for floor, wall, and roof systems, diaphragms, shear walls, fire-rated systems, and methods of finishing.
MSC floors and roofs can be engineered from light-gauge steel joists. The joists are attached to an outside wall, then span to an inside wall or column. Plywood forming, placed and blocked from the bottom side, provides the deck to pour, in place, 2 1/2" of concrete over a reinforcing mesh.
It is also used in building construction in the form of concrete shuttering panels, floors, walls and roofs. BWR grade plywood is used in making kitchen cabinets and other kitchen furniture. Marine plywood is used for making boats and ships.
A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used in the construction industry. SIP is a sandwich structured composite , consisting of an insulating layer of rigid core sandwiched between two layers of structural board, used as a building material .
This price spread means that a builder can save $700.00 on a 2,500 square foot house if osb is substituted for plywood sheathing on floors, walls, and roofs. A substantial savings to be sure. The trend among builders is to switch to osb.
