Blow-In Insulation
Loose-Fill Fiberglass & Cellulose Insulation for Attics, Walls, Remodels, and Retrofits
Coverage in Hard to Reach Areas
Blow-In insulation is designed to create consistent coverage across attics, enclosed wall cavities, and irregular spaces where traditional insulation systems may leave gaps. Loose-fill fiberglass or cellulose is installed with specialized equipment so the material can settle around framing, wiring, pipes, and other obstacles.
Because it works well in retrofit conditions, Blow-In is commonly used for attic upgrades, existing homes, remodels and areas where access is limited. Properly installed material helps reduce heat loss, improve indoor comfort and support better energy efficiency throughout the building.
Built for Long-Term Performance
Blow-In insulation helps improve the performance of the full energy envelope by adding coverage where buildings often lose energy. Inadequate attic or wall insulation can cause uneven temperatures, higher utility costs, drafts, and extra strain on heating and cooling systems.
Every building has different insulation needs based on age, layout, use, and existing insulation levels. Wyoming Insulation evaluates the space, identifies areas where heat loss is affecting performance, and installs a Blow-In system built for durability, efficiency, and long-term comfort.
Explore Insulation Options
Blow-In insulation is not the right fit for every project. Here are other systems we install.
Spray Foam
Expands to fill cavities and create an air seal in crawlspaces, rim joists, shops, and hard-to-seal areas.
Batt Insulation
Fiberglass, mineral wool, and sound batt insulation for walls, ceilings, remodels, retrofits, and new construction.
Continuous Insulation
Foam board and mineral board systems that help reduce thermal bridging and improve envelope performance.
Damp & Waterproofing
Foundation moisture protection systems designed to help prevent water intrusion below grade.

Frequently Asked Questions
Is Blow-In insulation a good option for older homes?
Yes. Blow-In insulation is often a good fit for older homes because it can improve attic or wall coverage without major demolition. It works well for remodels, retrofits, and insulation upgrades.
Should old insulation be removed before adding more?
Sometimes. If the existing insulation is wet, contaminated, compacted, damaged, or blocking proper air sealing, insulation removal may be recommended before new material is installed.
What is the difference between fiberglass & cellulose Blow-In?
Both are loose-fill materials used to improve coverage. Fiberglass is lightweight and commonly used in attics, while cellulose is denser and can be useful in certain retrofit applications.
Can Blow-In insulation help with ice dams?
It can help when paired with proper air sealing and attic ventilation. Ice dams are often caused by heat escaping into the attic, so improving insulation coverage can reduce one of the major contributing factors.
Will Blow-In insulation make my rooms feel more even?
Yes. Adding insulation to under-insulated attics or wall areas can help reduce cold spots, drafts, and uneven room temperatures.
How messy is the installation process?
Blow-In insulation is installed with specialized equipment and is usually a clean, efficient process. For attic work, most of the material is installed through a hose with limited disruption to the home.
Can Blow-In insulation be added over existing insulation?
In many cases, yes. If the existing insulation is dry, clean, and still in acceptable condition, Blow-In insulation can often be added over it to improve depth and performance.
How do I know how much Blow-In insulation I need?
The amount depends on the current insulation level, attic depth, wall cavity size, energy goals, and local performance requirements. Wyoming Insulation evaluates the space before recommending the right amount.
Will Blow-In insulation make my home less drafty?
It can help, especially when combined with air sealing. Blow-In insulation improves coverage, while air sealing helps close the gaps where outside air moves into the home.
Can Blow-In insulation be used in shops or outbuildings?
Yes, in some applications. Blow-In insulation can work in certain attic, ceiling, or enclosed cavity areas, but shops, pole barns, and metal buildings may also need spray foam, MBI, batt, or vapor control depending on the structure.
