Installing Installation in your Exterior Walls will help reduce the amount of money you save on heating and cooling costs, as well as your comfort level in your home.
When installing insulation make sure you check the R-value, which depends on the type of insulation.
What type of insulation requires less disturbance?
You will be able to install loose-fill or sprayed foam insulation without much disturbance to your home. Installing these types of insulations to your existing home is not only cost effective, but a good way to reduce your energy consumption.
