Why Attic Insulation Matters

Your attic plays a crucial role in regulating your home's temperature. Without adequate insulation, heat escapes in the winter and builds up in the summer, forcing your HVAC system to work overtime. This not only leads to higher energy bills, but also reduces comfort and puts unnecessary strain on your home’s systems.


Blown-in insulation offers a simple, cost-effective way to combat these issues—especially when paired with proper air sealing.

What Is Blown-In Insulation?

Blown-in insulation is a loose-fill material—typically cellulose or fiberglass—that’s evenly distributed across your attic floor using specialized equipment. It fills gaps and hard-to-reach areas much more effectively than traditional batts or rolls, creating a seamless thermal blanket.


Key Benefits:

  • Improved Energy Efficiency – Reduces heating and cooling loss
  • Fast, Non-Invasive Installation – No major disruptions to your home
  • Excellent Coverage – Fills corners, gaps, and irregular spaces with ease
  • Noise Reduction – Dampens sound transfer from outside and between rooms
  • Eco-Friendly Options – Cellulose is often made from recycled materials

Why We Recommend Cellulose — And How It Meets Today’s Standards

When it comes to blown-in attic insulation, both cellulose and fiberglass offer solid performance. However, for most homes, we recommend cellulose insulation as the superior choice.


Cellulose offers:

  • Higher density for better air resistance and thermal performance
  • Superior soundproofing, reducing noise from outside and between levels
  • Pest- and mold-resistant treatments for added protection
  • Excellent value, with better long-term efficiency compared to fiberglass


In addition, we install insulation to meet or exceed the R-50 standard, the current benchmark for attic insulation in Wisconsin's climate zone. This ensures that your home achieves optimal energy performance, meets modern building codes, and delivers lasting comfort and energy savings year-round.


With cellulose blown-in insulation, you get the best combination of performance, durability, and value—installed to the highest standard.
