10 Types of Insulation Materials Professional Home Insulation Companies UseIf someone asked you to name different kinds of insulation used in homes today you might be able to come up with a couple. Maybe the image of the Pink Panther cartoon character pushing a roll of pink fiberglass material comes to mind. Or perhaps you think of someone who looks a little like one of the Ghostbusters spraying foam insulation.

Confused? Don’t Worry!

You can see that there are a lot of choices. That can be confusing, but don’t worry. You don’t have to be an insulation expert to make the right choice. There are some home insulation installation contractors who only use one or two kinds of materials. They tend to take a “one-size-fits-all” approach to materials. That makes things easy for them, but is it the right solution for you?

That’s not how we do it at Mass Energy Lab Insulation. While we may install insulation in homes throughout the Boston area, we’re really problem solvers. We’re not interested in simply filling up space in your attic or basement with foam or fiberglass. We want to know exactly what your house needs to ensure that you get the best insulation solution—on that really addresses your home’s issues and provides you with the best comfort and value possible.

That’s why we do a thorough assessment of your home first, using sophisticated diagnostic tools such as infrared camera inspection to check your home for vapor barriers, moisture issues, missing insulation, pipe freezes, cold spots, and a host of other problems that can keep you from getting the insulation results you want. We want to understand your home and then design the right solution to give you a comfortable and efficient home.

Our job isn’t to confuse or confound you with too many choices. It’s also not to take away valid choices because it’s easier for us. Our job is to evaluate your home’s needs and then offer you solutions that will work best for you.
