Osb3 For Shed Roof

Lay sheets in rows with the long edge horizontal to the roof bottom.

Osb3 for shed roof.

I roofed my stable with 11mm sheets covered with cheap shed kennel felt three years ago. One of the nice things about plywood is the variety of options you can buy. The minimum osb panel size is 24 inches in any direction and each sheet end must rest on a rafter. Provide a 1 8 inch gap.

Still as good as day 1. So long water or sunlight doesn t make direct contact it ll be fine. Osb3 is just as good as regular shuttering ply. There are pressure treated grades marine grades that can be used in water fine hardwood.

Bitumen paint is no different to felting it for shed roofs. It wont delaminate if it gets wet its cheaper. Up until 2000 plywood held the majority of the market for wall roof and floor sheathing when it was surpassed by osb which as of 2018 held about 75 of the market share. Oriented strand board isn t plywood nor is it a type of particleboard fiberboard or wafer board and although it is a newcomer to a plywood.

Osb 3 is suitable for external use is fully structural whereas much plywood isnt despite what people think. Watch this now to learn how to avoid this same pr. I presume that this is as a result of poor experience with using osb2. One point that i found interesting was that the national house building council nhbc only permit the use of osb3 for sheathing to walls floors and roofs.

If there s a will there s always a way. Find osb sheathing osb at lowe s today. Can oriented strand board osb be used for roofing.
