Building a greener, more energy-efficient home starts with choosing the right insulation.
In the Midwest, where weather extremes are part of daily life, picking eco-friendly materials can make your home more comfortable — and help protect the planet at the same time.
Here’s a guide to the best sustainable insulation options in 2025 and why they matter more than ever.
1. Why Eco-Friendly Insulation Matters
Traditional insulation materials often use chemicals and manufacturing processes that harm the environment.
By choosing eco-friendly insulation, you can:
- Lower your home’s carbon footprint
- Improve indoor air quality
- Support sustainable manufacturing practices
- Save money on energy bills

3. What’s Best for Midwest Homes?
