Cellulose Insulation
Cellulose insulation is a dense, loose-fill insulation material commonly used in attics and wall cavities. It is well suited for retrofit applications and areas where consistent coverage, thermal performance, and air control are priorities.
Reitzel Insulation provides professional cellulose insulation services for residential and select commercial projects, helping property owners improve comfort, energy efficiency, and overall building performance.
Why Choose Cellulose Insulation
Cellulose insulation is denser than many other loose-fill insulation types, allowing it to resist air movement more effectively when properly installed. This density helps improve thermal performance while reducing drafts and temperature variation.
Cellulose insulation is often selected for projects where:
- Existing insulation levels are low or uneven
- Walls or attics require improved air control
- Retrofit installation is preferred over invasive construction
Recycled Material and Environmental Considerations
Cellulose insulation is manufactured primarily from recycled paper products, giving it one of the highest recycled contents among insulation materials. It is treated to resist fire, pests, and mould, supporting safe use in residential construction.
Because it requires less energy to manufacture than some other insulation types, cellulose insulation is often chosen by homeowners seeking to improve energy performance while considering environmental impact
Thermal Performance and R-Value
R-value measures an insulation material’s resistance to heat flow. Cellulose insulation provides strong thermal performance per inch and can achieve higher overall R-values by increasing installed depth.
Because it settles densely, cellulose insulation helps maintain consistent coverage across attic floors and within wall cavities, reducing gaps that can lead to heat loss.
Cellulose Insulation for Attics and Walls
Cellulose insulation is commonly used in:
- Attic floors and roof spaces
- Exterior wall cavities in existing homes
- Retrofit projects using drill-and-fill methods
In attic applications, cellulose can be installed quickly and evenly to achieve deep coverage. In wall applications, it can be dense-packed into cavities without removing interior finishes, making it a practical option for improving insulation in older homes.
When to Consider Cellulose Insulation
Cellulose insulation may be a good option if:
- Your home has older or insufficient attic insulation
- Exterior walls lack insulation
- You want to improve comfort without major renovations
- Drill-and-fill retrofit insulation is being considered
A professional assessment can help determine whether cellulose insulation is appropriate for your home and where it will provide the greatest benefit.
Air Control and Indoor Comfort
While no insulation replaces a dedicated air-barrier system, densely installed cellulose insulation can help limit air movement within building cavities. This contributes to improved comfort by reducing drafts and temperature swings.
Homeowners often notice:
- More consistent indoor temperatures
- Reduced cold spots
- Improved comfort during colder weather
Comparing Insulation Options
Cellulose insulation is one of several insulation methods available. Depending on building design, access, and performance goals, other insulation approaches may also be considered.

Cellulose Insulation FAQ
Cellulose insulation is primarily made from recycled paper products that are treated for fire resistance, pest control, and mould resistance.
Cellulose insulation is commonly used in attics and wall cavities, especially in retrofit and drill-and-fill applications.
Yes. Cellulose insulation is often used in older homes because it can be installed without removing existing walls or finishes.
Cellulose insulation is denser than some other blown insulation materials, which can improve air resistance and coverage consistency when properly installed.
