Why is 7/16 OSB so expensive?
Building material suppliers have to have 7/16 OSB to sell to customers, so many of them contract the product from mills. That means they are obligated to buy it regardless of current pricing. As they bought product at the higher prices, they were forced to raise their retail price to keep from losing money.
Can 7/16 OSB be used for sheathing?
Types of Sheathing Standard types of wood designed for roof sheathing are oriented strand board, known as OSB, and plywood, the most popular being OSB. Sheets of 7/16-inch thick, without edge support, can be used in an area where the snow load is 30 pounds per square foot.
What is the span rating for 7 16 OSB?
For example: 7/16-inch SHEATHING SPAN, 24/16 Exposure 1, 48 x 96 inches, square-edge, 200 pcs. The use of OSB-panels is governed by several basic guidelines.
Is 7/16 OSB good for exterior walls?
Install structural sheathing (plywood/OSB) in exterior walls to ensure the building will resist design wind pressures. Select the appropriate thickness for wood structural sheathing panels. Minimum: 7/16” thickness. (Exception: 3/8” for gable end walls structural sheathing.)
Is OSB or plywood better for roof sheathing?
Plywood Holds the Moisture Advantage Over OSB When plywood gets wet, it tends to swell. OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.
What side of OSB should face out?
smooth side
The smooth side has a better moisture resistance and will ultimately provide better performance against weather. Facing the board smooth side out will maximize its ability to keep moisture out of the structure. It is simple why manufacturers create roughness on OSB boards.
How thick should exterior plywood sheathing be?
The International Residential Code specifies 3/8-inch plywood for sheathing walls with a standard stud spacing of 16 inches, if the siding is nailed to the studs through the sheathing. If the nails penetrate the sheathing, but not the studs, the minimum plywood thickness that the IRC designates is 1/2 inch.
