Insulation FAQs

Common Questions From Michigan Homeowners

Have questions about spray foam, blown-in attic insulation, sidewall insulation, or insulation removal? Here are a few answers before your free estimate.

What type of insulation is best for my home?

It depends on the space. Spray foam is excellent for air sealing and hard-to-insulate areas, while blown-in cellulose is a strong choice for attic upgrades and sidewall insulation. During your estimate, Greenshield will inspect the area and recommend the best fit.

Do you offer free insulation estimates?

Yes. Greenshield Insulation offers free on-site estimates for homeowners throughout Mattawan, Kalamazoo, Portage, Paw Paw, Allegan, Plainwell, and nearby Southwest Michigan areas.

Can blown-in insulation be added over existing attic insulation?

Often, yes — if the existing insulation is dry, clean, and not damaged. If the attic has moisture issues, pests, heavy contamination, or poor ventilation, removal or correction may be recommended before adding new insulation.

What is sidewall insulation?

Sidewall insulation is commonly installed by drilling small access holes and dense-packing cellulose into wall cavities. It can help improve comfort in older homes without fully tearing open finished walls.

Do you install both open-cell and closed-cell spray foam?

Yes. Greenshield installs both open-cell and closed-cell spray foam depending on the project, budget, building assembly, and performance goals.

How do I schedule an insulation estimate?

You can call Greenshield Insulation at 269-743-3121 or submit a request through the website. We’ll review the project, schedule a time to inspect the space, and provide a clear recommendation.
