Osb comes in 4 by 8 foot sheets as does plywood but the manufacturing process allows the production of longer and wider ones.
11mm osb for shed roof.
Im fixing some tapco tiles to a roof that has 11mm osb board then battens on top.
I have rafters that are 40cms apart beneath the osb sheet.
Osb3 is just as good as regular shuttering ply.
Osb sold in the uk is made to comply with bs en 300 oriented strand board osb definitions classifications and specifications.
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.
9mm 11mm or 18mm.
The thickness of osb that you need varies on where it is used in a building.
Which would be better.
As with flooring you have a number of roof options with the standard to premium levels of protection from the elements.
Could a cover the boards with a tarp after boarding for a few weeks to a month before i felt fiberglass it.
Any advice much appreciated as i ve never had a shed with osb before.
The fixing guide says i need 18mm.
Will the thickness make a difference.
Thicknesses range from 5 16 to 3 4 inch and the proper.
Also make sure that you get your supporting timbers at the correct spacing.
Will the 11mm board suffice.
So does it matter on the what timber sheets i use to board the roof.
For shed construction there are two commonly used grades of osb.
Typically 3 4 18mm for floors and 3 8 9mm for walls and 1 2 11mm roof.
Does it has to be osb3 or will osb2 do.
Would a 9mm ply board be better than 18mm osb.
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.
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.
To make your shed complete the final step is building the shed roof.
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.
Most osb suppliers have a load span table giving a guide to the spacing of timbers for different thicknesses.
A good alternative to ply wood and usually cheaper we stock osb3 board in a selection of sizes.
Still as good.
It is a long document with many parts and subsections.
