Boards required

[eandg]

I know there's calculators online to calculate bricks and blocks required. Just wondering if there's any easy reckoners for working out the number of insulation/plaster boards required (and the most efficient way to fit them)?

Cant really provide any help but I just measured all my wall and roof areas using autocad from the architect drgs. 

If you have the drgs you could use a free package to measure the areas?

Thanks - have the drawings so will see if I can get some free package to do so.

If you take the total area and add 

5 % to the total for waste

Thanks - wasn't sure how many offcut panels could be reused.

Remember that roof and walls will be different thicknesses as most put 2 layers on roof I think. In my budget i think i doubled it up to be safe, but still need to work out final numbers and specs.

If it’s standard ceilings and walls 

You normally put single layer of duplex  15 mil on the underside Of the trusses 

15 plain on the underside of the floor joists 

12 mil moister to bathroom walls 

12 mill wallboard for the rest 

Insulated board for the slopes
