Does your attic insulation measure up?

Investments in attic insulation will save you money on heating and cooling plus keep you comfortable. Check the table below to see how much insulation you may need, how much it might cost, our rebate amount and the payback period.

Building codes change over time and so does the depth of insulation installed in attics.  In most older houses, an investment in attic insulation will pay for itself in 2 to 6 years.

It is recommended to have 18 inches of attic insulation (R-50). Columbia Water & Light will help finance your project  with rebates and loans through our Home Performance with Energy Star program.
