Everyone knows that a properly done basement wall insulation can help you reduce your energy bills.

The actual annual savings from proper basement wall insulation can vary depending on your climate, type of heating system, fuel cost and occupant lifestyle.

Disadvantages of using basement wall insulation

1) The costs for basement wall insulation might at one point exceed the ones necessary for basement ceiling insulation.

2) Installation is pretty expensive for an existing building unless a perimeter drainage system is also being installed.

3) Many of the existing exterior insulating materials are susceptible to insect infestation.

4) If the soil surrounding the house contains radon gas, the house will need a mitigation system underneath the basement floor.

So when planning to perform a basement wall insulation always remember that it would be good to analyze all the options before.
