Input length width and desired r value of the area to be insulated.
Calculating insulation needed for attic.
Inspecting your attic insulation first things first you need to go up into your attic inspect the condition of the insulation and calculate the current level of insulation.
Square feet needed 10 x 25 250 m therefore the approximate square feet of insulation material needed is 250m.
Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
Use these insulation calculators to estimate how much insulation you may need and how much you could save on your energy bills.
Insulation calculation once you have determined which r value you need you can calculate how much insulation you need.
This calculator is to be used as an estimating tool only.
Refer to the project guide for more information on determining the right r value for your home.
Input length and width of area to be insulated.
Your attic should have a certain amount of insulation in it and the recommended level of insulation for your attic is dependent on where you live.
The length of the area feet inches the width of the area feet inches the coverage of one bag cubic feet the r value per one inch of thickness of the insulation settled the desired r value.
