9mm 11mm or 18mm.
11mm osb for shed roof.
I need to buy a shed this week before prices go up.
So i will try and simplify what you need to know.
As with flooring you have a number of roof options with the standard to premium levels of protection from the elements.
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.
The thickness of osb that you need varies on where it is used in a building.
Osb sold in the uk is made to comply with bs en 300 oriented strand board osb definitions classifications and specifications.
The fixing guide says i need 18mm.
Will the 11mm board suffice.
8 x 6 11mm shiplap with osb roof floor 8 x 6 12mm shiplap with t g roof and floor.
Still as good.
Osb comes in 4 by 8 foot sheets as does plywood but the manufacturing process allows the production of longer and wider ones.
Which would be better.
For shed construction there are two commonly used grades of osb.
Most osb suppliers have a load span table giving a guide to the spacing of timbers for different thicknesses.
Also make sure that you get your supporting timbers at the correct spacing.
A good alternative to ply wood and usually cheaper we stock osb3 board in a selection of sizes.
Could a cover the boards with a tarp after boarding for a few weeks to a month before i felt fiberglass it.
Would a 9mm ply board be better than 18mm osb.
I have rafters that are 40cms apart beneath the osb sheet.
It is a long document with many parts and subsections.
So does it matter on the what timber sheets i use to board the roof.
Typically 3 4 18mm for floors and 3 8 9mm for walls and 1 2 11mm roof.
Any advice much appreciated as i ve never had a shed with osb before.
I roofed my stable with 11mm sheets covered with cheap shed kennel felt three years ago.
Will the thickness make a difference.
Osb3 is just as good as regular shuttering ply.
Thicknesses range from 5 16 to 3 4 inch and the proper.
To make your shed complete the final step is building the shed roof.
Replacement shed roof osb or ply.
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.
