Calculating Bags Required – Ceiling, Wall, Underfloor

It’s quite simple to calculate how many bags of insulation you will need for your project. The basic steps are as follows.

  • Measure the total area to be insulated
  • Deduct any other areas not requiring insulation such as windows and doors
  • Multiply the number by 0.9 , to allow for the fact that the framing also takes up around 10% of the total area to be insulated
  • Divide this number by the number of m2 in a bag of insulation

Here’s an example to demonstrate:

You have a ceiling which is to be insulated with R4.0 Earthwool batts. The ceiling joists are at 450mm centres, so you will need the 430mm wide batts.

  • Ceiling area is 10.4 x 11.5 metres (120m2)
  • (No allowance required in this case for areas not requiring insulation)
  • 120 x 0.9 = 108
  • One bag of Earthwool R4.0/430mm contains 9m of insulation
  • 108m2 divided by 9m per bag = 12 bags
