The thickness of osb that you need varies on where it is used in a building.
11mm osb for shed roof.
Im fixing some tapco tiles to a roof that has 11mm osb board then battens on top.
For shed construction there are two commonly used grades of osb.
Thicknesses range from 5 16 to 3 4 inch and the proper.
I have rafters that are 40cms apart beneath the osb sheet.
Any advice much appreciated as i ve never had a shed with osb before.
Osb sold in the uk is made to comply with bs en 300 oriented strand board osb definitions classifications and specifications.
Osb3 is just as good as regular shuttering ply.
9mm 11mm or 18mm.
Osb comes in 4 by 8 foot sheets as does plywood but the manufacturing process allows the production of longer and wider ones.
Replacement shed roof osb or ply.
As with flooring you have a number of roof options with the standard to premium levels of protection from the elements.
I roofed my stable with 11mm sheets covered with cheap shed kennel felt three years ago.
Could a cover the boards with a tarp after boarding for a few weeks to a month before i felt fiberglass it.
Does it has to be osb3 or will osb2 do.
The fixing guide says i need 18mm.
Will the 11mm board suffice.
A good alternative to ply wood and usually cheaper we stock osb3 board in a selection of sizes.
I need to buy a shed this week before prices go up.
8 x 6 11mm shiplap with osb roof floor 8 x 6 12mm shiplap with t g roof and floor.
Still as good.
Would a 9mm ply board be better than 18mm osb.
So does it matter on the what timber sheets i use to board the roof.
Osb board a staple in a wide range of construction projects osb board is used for everything for sheeting through to structural sheathing and more.
There is also a plastic sheet dpm sheet as its only a field shelter then sarkit on top of the osb board then 32 x 25mm battens.
To make your shed complete the final step is building the shed roof.
Most osb suppliers have a load span table giving a guide to the spacing of timbers for different thicknesses.
For heavy duty roofing you may want to opt for an 11mm tongue and groove roof additional roof trusses can offer even more support for your shed roof.
Also make sure that you get your supporting timbers at the correct spacing.
Will the thickness make a difference.
Which would be better.
