X= The glue used is rated for exposure to moisture (notwaterproof, but it won’t fall apart in light rain). So, CDX is basicallyconstruction-grade plywood, strong and cheap, made for stuff like subfloors and roo
It is very effective on steeper slopes as well. Install approximately 2” of closed-cell spray foam insulation on the underside of the roof sheathing. Ensure it adheres tightly to all rafters, roofing nails, and penetrations. Fill the rest of the rafter cavities with fiberglass batts. Install...
Sheathing:Sheathing creates a structural panel, reinforcing a shear wall so that it doesn’t collapse on itself. This layer is typically plywood or oriented strand board (OSB). Common Shear Wall Materials A shear wall can be made from a variety of materials, but the most common ones are con...
PROBLEM TO BE SOLVED: To enable the use of a separator whose threaded part length is the same as that for a wooden mold mateiral such as plywood and to simplify on-site parts management when using both metallic and wooden molds by providing a projection of a predetermined height on the s...
Finally, the rafters are covered with sheathing (typically plywood or OSB panels or closely spaced boards). Truss Roofs Most new homes today are framed with roof trusses rather than the traditional "stick frame" assembly described above. Trusses use the same principle of triangulation but have ...

While most experts agree that plywood and oriented strand board share virtually the same properties in terms of strength and durability, OSB is less expensive, which can reduce overall building costs. Oriented strand board also offers a more uniform and consistent construction, resulting in greater ...
One might think that benefits solar gain in a heating climate - at least when the roof is not snow-covered. But the same study found that the black roofs also loste heat faster than the white roofs, more or less evening the score - at least when measuring sheathing temperature changes....
