As the push for sustainability continues to grow, insulation companies are stepping up with greener, smarter solutions.
In 2025, choosing the right eco-friendly insulation brand doesn’t just reduce your environmental footprint — it also increases energy efficiency, improves air quality, and adds value to your Midwest home.

Here’s a breakdown of the best green insulation brands on the market today and why they’re worth considering.
