Insulating Using Blown Insulation - Metric Measurements
Calculate the RSI value, the metric equivalent of the R value for blown insulation. To convert an R value to RSI divide the R value by 5.67826.
Attic/Ceiling Insulation-Blown/Plus Cost Metric Measurements
The Calculation
- the length of the area (metres)
- the width of the area (metres)
- the coverage of one bag (cubic metres)
- RSI value based on 25.4 millimetres depth (settled)
- the desired RVI value
- the cost of one bag
Results
- the square metres of the area
- applied depth of insulation (the height of placing the insulation before it settles in millimetres)
- required depth of insulation (settled depth in millimetres)
- volume of insulation needed (in cubic metres)
- number of bags needed (# whole plus partial bags)
- cost of the material (based on whole bags needed)
Check manufacturers' labels for accurate coverage values on insulation and sealant.
This calculator is designed for accurate estimates but can be adjusted based on specific wall configurations.
