Blown-In Insulation
Blown-in insulation is one of the most common and effective insulation methods used in attic and roof spaces. It is designed to improve thermal performance by evenly filling open areas and reducing heat loss through the upper levels of a home.
Reitzel Insulation provides professional blown-in insulation services to help homeowners improve comfort, energy efficiency, and overall building performance.
Why Blown-In Insulation Is Commonly Used
Attics are one of the primary areas where heat escapes from a home. Blown-in insulation allows material to be distributed evenly across attic floors, filling gaps and irregular spaces that can be difficult to insulate using other methods.
Blown-in insulation helps:
- Reduce heat loss in winter
- Limit heat gain in summer
- Improve overall comfort throughout the home
- Support more consistent indoor temperatures
Because coverage depth can be adjusted, blown-in insulation can be tailored to meet performance goals for each home.
Understanding R-Value and Insulation Depth
The effectiveness of blown-in insulation depends on both the material used and the depth of installation. R-value is a measure of insulation’s resistance to heat flow — higher values indicate better thermal performance.
Adding or upgrading blown-in insulation can significantly improve attic performance when existing insulation is insufficient or uneven.
Blown-In Insulation for Attics and Roof Spaces
Blown-in insulation is most commonly used in:
- Attic floors
- Roof spaces with open framing
- Areas with limited access
Its loose-fill nature allows insulation to flow around obstructions such as wiring, ductwork, and framing, helping create more uniform coverage.
Comfort, Air Control, and Indoor Environment
While blown-in insulation primarily addresses thermal performance, it also contributes to improved indoor comfort by reducing temperature differences between rooms and limiting cold spots caused by heat loss through the attic.
When combined with proper air sealing, blown-in insulation supports a more stable indoor environment and improved year-round comfort.
When to Consider Blown-In Insulation
You may want to consider blown-in insulation if:
- Your attic has low or uneven insulation levels
- Rooms feel cold in winter or hot in summer
- Heating and cooling costs are higher than expected
- Your home has never had an attic insulation upgrade
A professional assessment can help determine whether blown-in insulation is the right solution or if another insulation method may be more appropriate.
Choosing the Right Insulation Method
Blown-in insulation is one of several insulation options available. Depending on attic design, access, and performance goals, other methods may also be considered.

Blown-In Insulation FAQ
Blown-in insulation is commonly used in attics and roof spaces to improve thermal performance and reduce heat loss.
Blown-in insulation fills gaps and irregular spaces more evenly than batts, helping achieve more consistent coverage.
In many cases, blown-in insulation can be added over existing insulation to increase depth and improve performance.
Yes. Blown-in insulation is often used in older homes where attic access is limited or insulation levels are low.
