Improve comfort, reduce drafts, and lower your monthly utility bills with dense-pack blown-in cellulose insulation.
High-performance cellulose fits behind insulation in existing walls, attics, rim joists, and hard-to-reach framing cavities without major demolition.
Cellulose is made from tightly packed recycled fibers treated with natural fire retardants, creating a dense, air-resistant material that performs exceptionally well in NEPA’s cold winters and humid summers.
For older homes and newer builds alike, blown-in cellulose offers a safe, long-lasting, and environmentally friendly way to reduce energy loss. A dense-pack installation fills every corner of your wall cavities, eliminating air gaps and preventing drafts that drive up heating and cooling costs.
EnergySmart installs cellulose through small openings in your walls or attic cavities, creating a seamless thermal barrier that boosts comfort without disrupting your home. With its ability to slow air movement far more effectively than batts, cellulose delivers strong year-round performance.
When properly installed, blown-in cellulose insulation:
- Provides a higher density than fiberglass for improved air resistance
- Reduces heating and cooling costs throughout NEPA’s extreme seasons
- Offers excellent noise-reduction benefits
- Contains fire-retardant and pest-resistant additives
- Can last 25–30 years or more with proper air sealing
- Environmentally sustainable
Typical R-values with blown-in cellulose:
- Attics: Up to R-60
- Walls: Up to R-23
- Floors: Up to R-50
- Cathedral Ceilings: Up to R-38

Uninsulated Walls and Attics Could Be Burning a Hole in Your Pocket
Heating costs have been rising in Northeast Pennsylvania for over a decade and the problem is worse for older homes with little to no insulation. Uninsulated spaces allow heat to escape rapidly, leaving only a layer of drywall between your conditioned air and the outdoor temperatures.
Without proper insulation:
- Drafts move freely through wall cavities
- Moisture and allergens infiltrate your living space
- Furnaces and AC units must work harder, costing more to operate
- Rooms become unevenly heated or cooled
- Sound travels effortlessly from outside or between rooms
Over time, the energy lost through uninsulated walls and attics can cost homeowners thousands of dollars.
There’s an easy solution to insulate behind existing walls and tight spaces with minimal disruption to your home.
Blown-In Cellulose Is an Economical and Efficient Solution for NEPA Homes
Dense-pack cellulose fills voids that other insulation types can’t reach, making it perfect for drafty, aging homes across NEPA. With only a small hole drilled into your siding or drywall, EnergySmart can fully insulate enclosed cavities and create a seamless thermal layer without tearing apart your home.
Cellulose naturally resists air movement, giving it one of the best real-world performance ratings among traditional insulation types. When paired with proper air sealing, it dramatically cuts energy loss, improves indoor air quality, and boosts comfort year-round.
- Perfect for older homes with empty wall cavities
- Ideal for attics where fiberglass settles or underperforms
- Safe, fire-resistant, environmentally friendly material
- Dense enough to reduce air infiltration and noise
- Strong performance in both winter cold and summer humidity
Professional installation from EnergySmart’s team of trained technicians guarantees your cellulose insulation will encounter minimal settling and last for decades without the risk of degradation.

Blown-In Cellulose FAQs
What Is Blown-In Cellulose Insulation?
Blown-in cellulose insulation consists of cellular plant products, such as paper, wood, or blow-in fiberglass, that are densely packed and installed using a special blower tool. Cellulose mostly consists of recycled materials–giving it a high eco-rating–and has the consistency of feathers or clumpy sand.
Cellulose is a popular choice for existing homes with little to no insulation, as it can be installed without ripping out the drywall. Thanks to its consistency, it is effortless to spread and form in tight spaces, creating a dense layer of insulation between exterior home components.
Despite being made of cellulose products, cellulose insulation is treated for fire retardancy and given a Class I fire safety rating. These products also naturally repel pests, making them a great choice in any home.
Most cellulose insulation is used for attics between flooring joists or installed in existing walls with no prior insulation. One downside of cellulose is that it tends to collect at the bottom of spaces, leaving gaps at the top of walls and joists if improperly installed. For this reason, it’s important to have professionals install cellulose, as they will have access to the proper equipment for this task.
How Is Blown-In Cellulose Installed?
Cellulose is blown in and can be installed directly into your wall or attic cavity using a specialty blower machine. Using a wet mix of water and cellulose, the blower compacts the cellulose into the empty cavity space, helping it stick and fill in any open crevice. Since cellulose is naturally a loose and light product, it still allows for some airflow and sheds moisture, eliminating any concerns of mold or degradation.
Is Blown-In Cellulose Good for Older Homes?
Yes. Blown-in cellulose is one of the best insulation upgrades for older homes because it can be installed behind existing walls without demolition. It fills irregular cavities commonly found in pre-1970s framing and dramatically improves comfort and energy efficiency.
How Long Does Blown-In Cellulose Insulation Last?
When properly installed and kept dry, blown-in cellulose can last 20–30 years, and in many cases even longer. Its lifespan depends on density, air sealing, and moisture control—three areas EnergySmart ensures are handled correctly during installation.
Does Cellulose Insulation Settle Over Time?
Yes, cellulose naturally settles, but professional dense-pack installation prevents performance loss. EnergySmart installs cellulose at a higher density than DIY machines can achieve, minimizing settling and ensuring full cavity coverage for years.
Is Blown-In Cellulose Environmentally Friendly?
Absolutely. Cellulose is made of up to 85% recycled materials, primarily paper fibers. It’s one of the greenest insulation products available and requires significantly less energy to manufacture than fiberglass or foam alternatives.
