TRUE NORTH INSULATION | BLOW-IN INSULATION

Blow In Insulation in Kalispell & the Flathead Valley, MT

Blow-in insulation, also called loose fill, is the practical choice for attics, existing wall cavities and hard-to-reach spaces where getting a batt in cleanly is not realistic. Using specialized equipment that breaks apart the loose fill material and pushes it through a hose, the fine fibers pile and settle into a seamless thermal blanket that slows heat movement without leaving the gaps and voids that hand-fitted material tends to produce. True North Insulation installs blow-in throughout Kalispell, Bigfork, Somers, Lakeside, Polson and the wider Flathead Valley, and it is often the right answer for upgrading an older home.

HOW LOOSE FILL WORKS

How Blow In Insulation Works

The material is fed into a hopper, mechanically separated into loose fibers, and delivered through a hose to the cavity. As it lands it creates tiny pockets of trapped air, and because air is a poor conductor of heat when it cannot move, those pockets are what slow thermal transfer. The advantage over pre-cut material is coverage. Loose fill flows around wiring, plumbing, framing irregularities and truss members, filling the awkward corners of an attic that a batt has to be cut around.

We use high-quality cellulose or fiberglass materials depending on the application, and modern loose fill comes with fire-resistant and mold-resistant options.

BETTER COVERAGE. BETTER COMFORT.

Benefits for Flathead Valley Homes

Excellent value on retrofits

For an attic that is under-insulated, blow-in delivers the largest thermal improvement per dollar of any option we install.

Even, seamless coverage

Depth is consistent across the whole plane, with no gaps at the edges where batts get compressed or cut short.

Reaches what other materials cannot

Existing closed wall cavities, low-clearance attic edges and irregular spaces are all accessible through a hose.

Comfortable in both seasons

The same thermal blanket that keeps heat in through a Montana winter keeps the upstairs from overheating in July.

Fire and mold resistant options

Treated cellulose and fiberglass loose fill are available with both properties, which matters in an attic that will never be inspected again.

WHERE WE INSTALL IT

Where We Use Blow In Insulation

Attics and attic floors are the most common application by a wide margin. We also use blow-in for existing wall cavities accessed through drill-and-fill, floor cavities over unconditioned space, and topping up attics that have settled below their original depth. On retrofit jobs we frequently pair blow-in with targeted air sealing at the attic plane, because adding depth over an unsealed ceiling gives back much of the gain.

FROM INSPECTION TO CLEANUP

Our Blow In Process

01

Attic inspection.

We measure existing depth, check for moisture staining, look at ventilation, and confirm there is no knob-and-tube or damaged wiring.

02

Air sealing first.

Penetrations at the ceiling plane get sealed before any loose fill goes down, because covering a leak does not stop it.

03

Baffles and protection.

Soffit baffles go in to keep the material out of the vents, and heat-producing fixtures are dammed off.

04

Installation to depth.

Material is blown to the specified depth with markers placed so the depth can be verified later.

05

Depth verification.

We confirm coverage across the full plane, including the perimeter where depth is most often short.

06

Cleanup and walkthrough.

Equipment and material are cleared out and we review the finished depth with you.

ATTENTION TO THE DETAILS

Why Choose True North for Blow In Insulation

The failure mode in blow-in work is depth that is right in the middle of the attic and thin at the edges, where nobody looks. We install to depth across the whole plane, we baffle the soffits so the ventilation still works, and we seal the ceiling penetrations first.

COMMON QUESTIONS

Blow In Insulation FAQ

Can you blow new insulation over what is already up there?

Usually yes, as long as the existing material is dry and free of contamination. If it is damp, rodent-damaged or moldy, it comes out first.

Cellulose or fiberglass?

Both perform well. Cellulose is denser and slightly better at resisting air movement, fiberglass does not absorb moisture. We recommend based on the specific attic.

Will it settle over time?

Loose fill settles somewhat by design, which is why we install to a settled-depth specification rather than an initial depth.

How much does my attic need?

Zone 6 and 7 attic recommendations are considerably higher than most Flathead Valley homes currently carry, particularly anything built before the mid-1990s. We measure and tell you where you stand.

Is it messy?

There is dust during installation, which is why we contain the work area and clean up thoroughly. The living space is protected throughout.
