Doorbell Installation FAQs, answered by experts

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Costs depend on area size, material thickness, and site preparation needs.
