Cut Down on Your Energy Bill with Blown-In Insulation
Heating and cooling account for the largest portion of most utility bills. Without proper insulation, much of that energy escapes through the attic, walls, or floors. Blown-in insulation fills these hidden gaps, boosting your home’s efficiency and reducing strain on your HVAC system.
How blown-in insulation helps lower costs:
- Seals Air Leaks: Loose fill fibers settle into cracks and voids where traditional batts can’t reach.
- Improves R-value: Higher insulation performance means your home retains heat in winter and stays cooler in summer.
- Reduces HVAC Strain: Less energy loss means your heating and cooling system runs less often, extending its lifespan.
According to ENERGY STAR, upgrading insulation can cut heating and cooling bills by up to 15% annually, with even greater savings in older homes. That means blown-in insulation often pays for itself within just a few years.
What is Blown-In Insulation?
Blown-in insulation, sometimes called loose-fill insulation, is exactly what it sounds like. Instead of laying down rolls of material, small fibers are blown into your attic, walls, or other cavities through specialized machinery.
This method creates a soft blanket of insulation that fills every gap, wrapping snugly around pipes, wires, and framing.
Because it settles into hard-to-reach spaces, blown-in insulation provides more complete coverage than traditional batts, which makes it a great choice whether you’re updating an older home or finishing new construction.
There are a few different materials used for blown-in insulation:
- Cellulose: Made from recycled paper and treated to resist fire, pests, and mold, cellulose is known for its excellent efficiency. It holds heat in during cold winters and keeps it out during hot summers, while also helping to quiet outside noise.
- Fiberglass: Lightweight, affordable, and naturally fire-resistant, fiberglass is widely available and a solid option if you’re working with a tighter budget. It generally doesn’t perform as well as cellulose, though, so more material may be needed to achieve the same level of comfort.
- Rockwool (mineral wool): Crafted from natural stone, rockwool is extremely durable and fire-resistant. It’s also great at blocking sound, but it tends to cost more and isn’t as commonly used throughout an entire home.
Of these options, cellulose is often the top pick. It combines high performance with eco-friendly materials and built-in safety features. Its dense coverage reduces air leaks more effectively than fiberglass, which helps cut energy bills and makes your home feel more comfortable year-round.
Benefits of Blown-In Insulation
Adding blown-in insulation to your home does more than just lower monthly bills. It makes your home more comfortable, safer, and healthier for the people living inside.
Non-Combustible
Cellulose blown-in insulation is treated with borate, a mineral that makes it highly resistant to fire. This extra step helps slow the spread of flames and provides an added layer of protection for your home. Fiberglass and rockwool also have natural fire-resistant qualities, giving you peace of mind no matter which option you choose.
Noise Reduction
One of the hidden perks of blown-in insulation is how much quieter your home feels. Because the material fills every cavity, it helps block outside noise from traffic, weather, or even loud neighbors. It can also soften sound between rooms, making for a more peaceful living environment.
Fast to Install
Blown-in insulation is a quick upgrade with a big impact. Using specialized equipment, our team can often complete attic installations in just a few hours. Unlike batt insulation that needs to be cut and fitted, blown-in material naturally settles into tight corners and tricky spaces, giving you complete coverage with less disruption to your day.
High Energy Efficiency
Dense coverage means blown-in insulation is excellent at holding heat in during the winter and keeping it out during the summer. That consistent barrier helps your HVAC system run more efficiently, which not only saves money but also keeps your home’s temperature more even from room to room.
Lowers Condensation
Blown-in insulation also helps control moisture. Keeping indoor temperatures more stable reduces the chance of condensation forming on walls, ceilings, or ductwork. That lowers the risk of mold and mildew while protecting the overall health of your home’s structure and indoor air quality.
Your Go-To Cellulose Blown-In Insulation Contractor
When it comes to blown-in insulation, not every material delivers the same results. That’s why at Larson Home Services, we often recommend cellulose insulation. It strikes the right balance of efficiency, safety, and sustainability, making it a wise choice for many homeowners.
Cellulose is made from recycled paper and treated to resist fire, so it’s both protective and eco-friendly. Its dense coverage fills in the little gaps where air likes to sneak through, which means fewer drafts, less noise from outside, and a home that simply feels more comfortable.
What sets cellulose apart is how well it handles Wisconsin and Minnesota’s extreme seasons. Whether it’s below-zero winter nights or sticky summer days, cellulose helps keep indoor temperatures steady, so your home stays cozy in the winter and cooler in the summer without putting extra strain on your HVAC system.
Cellulose vs. Fiberglass and Rockwool
While fiberglass insulation is lightweight, affordable, and naturally fire-resistant, it usually has a lower R-value per inch than cellulose. That means you may need more material to reach the same level of performance. It can work for budget projects, but it doesn’t provide the same dense coverage or sound control that cellulose does.
Rockwool (mineral wool) is another option. It’s highly durable, fire-resistant, and great at blocking noise. However, it tends to be more expensive and is less commonly used for insulating entire homes.
That’s why many homeowners turn to cellulose insulation. It offers the right balance of efficiency, safety, and affordability, along with the added benefit of being eco-friendly.
