Current building codes push homeowners with old homes to improve or change their insulation. Usually, they are on the fence when it comes to choosing between batt and blown-in insulation.
Which is better?It depends.
When it comes to longevity, both can last a hundred years — more than the amount of time you will own your house. The only thing that can degrade or ruin both these insulation materials is when they are poorly installed.
Aside from that, both have comparably similar R-value, and the difference in their costs is not significant.
How will you choose one over the other?If your walls are still exposed, you can use batt insulation. However, if your walls are already covered with drywall, you will need to remove them to install batt insulation. This will take more time and money since you also need to put the drywall back.
If you do not want to go through that invasive procedure, you can opt for blown-in insulation instead, as you or the contractor only need to "blow-in" the confetti-like insulation material.
However, note that blow-in has one major disadvantage: the insulation materials settle down a few inches per year. This means that an empty uninsulated space will be created, and you need to blow-in another batch of insulation.
You can install both of these insulation types yourself. However, if you are going to insulate multiple walls and your attic, you should call us for help. We can tackle your home's insulation and help you decide which material is ideal for your situation.
