Efficient Blown-In Insulation for Better Comfort & Energy Savings

Upgrade attic insulation performance, reduce energy waste, and maintain a consistent, cozy climate inside your home, no matter how extreme the Colorado weather gets.

Improve Attic Performance, Comfort & Energy Efficiency

Blown-in insulation is one of the most effective ways to improve attic energy performance and maintain comfortable indoor temperatures throughout the year. It is commonly installed in existing homes where insulation levels are outdated, uneven, or no longer performing efficiently.

Designed to cover open attic spaces evenly, blown-in insulation fills gaps around framing, wiring, pipes, and difficult-to-reach areas more effectively than many traditional insulation methods.

What Is Blown-In Insulation?

Blown-in insulation is a loose-fill insulation material installed using specialized equipment that distributes insulation evenly across attic floors and open cavities. The material settles into small gaps and irregular spaces to create more consistent thermal coverage throughout the attic.

Blown-in insulation is commonly made from:
  • Fiberglass
  • Cellulose
  • Mineral fiber materials

Because the insulation spreads evenly across the attic surface, it helps reduce heat transfer and improve overall home efficiency.

Why Attic Insulation Is Important

Your attic is one of the largest areas of energy loss in the home. During colder months, heated indoor air rises and escapes through under-insulated attic spaces. During warmer months, attic heat transfers downward into living areas, making cooling systems work harder.

Proper attic insulation helps:
  • Reduce heating and cooling costs
  • Improve indoor comfort
  • Minimize temperature fluctuations
  • Reduce HVAC strain
  • Improve overall energy efficiency


Many older homes still have insufficient attic insulation, making upgrades one of the most valuable energy-efficiency improvements homeowners can make.

Benefits of Blown-In Insulation

Cellulose Blown-In Insulation

Cellulose insulation is made primarily from recycled paper materials treated for fire resistance. It is known for dense attic coverage and strong thermal performance.

Common Benefits:
  • Dense coverage around attic gaps
  • Good thermal resistance
  • Eco-friendly material composition
  • Effective sound reduction
Fiberglass Blown-In Insulation

Fiberglass blown-in insulation uses loose fiberglass fibers designed to create a thermal barrier throughout attic spaces.

Common Benefits:
  • Lightweight installation
  • Moisture-resistant properties
  • Long-lasting performance
  • Effective attic coverage

Frequently Asked Questions

How long does blown-in insulation last?

Blown-in insulation can last anywhere from 20 to 30 years, and in ideal conditions, up to a lifetime. However, its lifespan can be significantly shortened if it is subjected to roof leaks, heavy moisture, mold, or pest infestations. We recommend regular attic inspections to ensure it remains effective.

Yes, it is one of the best choices for existing homes. Because it is blown in as a loose-fill material through a hose, it can easily fill awkwardly shaped attics, tight corners, and walls without requiring major demolition. It seamlessly covers gaps over existing, older insulation to instantly boost your home’s thermal barrier.

Absolutely. By sealing off the top of your home and preventing heated or cooled air from escaping into your attic, blown-in insulation can reduce your heating and cooling costs by up to 15% to 20%. It takes the strain off your HVAC system, leading to immediate monthly savings.

Yes, all loose-fill insulation will settle slightly after installation, which is completely normal. Materials like cellulose may settle by about 10% to 20%. Because we anticipate this natural settling, our professional team installs the material to a specific “settled thickness” and density to guarantee your attic retains its target R-value for decades to come.
