Insulating your attic is one of the most effective ways to improve energy efficiency, reduce heating and cooling costs, and create a more comfortable living environment year-round. Among the various types of insulation available, blown-in insulation is a popular choice for homeowners looking to upgrade their attic’s thermal performance.
Why Attic Insulation Matters
A poorly insulated attic allows warm air to escape in winter and hot air to enter in summer, forcing your HVAC system to work harder and driving up your utility bills.
Proper attic insulation helps:
- Maintain a consistent indoor temperature
- Prevent ice dams during winter
- Reduce your energy consumption and monthly bills
- Extend the life of your heating and cooling systems
- Improve indoor air quality by minimizing drafts and moisture issues
What Is Blown-In Attic Insulation?
Blown-in insulation (also known as loose-fill insulation) consists of small particles of insulating material blown into place using specialized equipment, creating an even, seamless layer of insulation across the attic floor or within wall cavities.
Materials used for blown-in insulation include the following.
- Fiberglass: Made from recycled glass and sand; lightweight and moisture-resistant
- Cellulose: Made from recycled paper products treated with fire retardants; eco-friendly and dense
- Mineral wool: Made from rock or slag; naturally fire-resistant and durable
