Blown-In Insulation in Sherman, TX

An under-insulated attic is the single biggest reason a Texas home is hard to keep comfortable and expensive to run. We blow in cellulose or fiberglass to R-38 (Texas code) or R-49 (DOE recommended), with proper baffles, a dam, and an access platform done right. It's the comfort upgrade that ties everything else together — pair it with duct sealing and damper work and one crew can tighten up the whole home's efficiency in a coordinated visit, so every system you've invested in actually holds its temperature. Serving Sherman (3 ZIP codes, 44k residents) and surrounding neighborhoods with same-week scheduling.

What is it

Blown-In Insulation in Sherman

Blown-in insulation is the loose-fill installation method: cellulose or fiberglass machine-blown across the attic deck to a verified depth. It's a thermal layer that conforms around every joist, wire, and obstruction without the gaps a hand-cut batt leaves — but loose fill slows heat, it doesn't air-seal, so depth and density are what make it perform.

Blown-In Insulation in Sherman — FAQ

Cellulose or fiberglass — and how does that choice affect the installed depth?

Reaching the same R-value target takes noticeably more inches of fiberglass, which delivers about R-2.5 per inch, than cellulose at roughly R-3.7 per inch. Each material has trade-offs: cellulose packs denser and resists air drifting through the blanket, though it weighs more and settles more over time, while loose-fill fiberglass stays light, barely settles, and won't wick water if the attic ever leaks. Our crews read each product's coverage chart and blow to that material's own correct depth, because inch-for-inch the two simply are not equivalent.

Why does loose fill need to be 'over-blown'?

Settling is the reason. Cellulose compresses more than fiberglass, and either way the blanket you see on install day sits lower six weeks later. So we deliberately install above the final R-target, planning the depth so the SETTLED blanket still meets spec once it compacts. A crew that blows only to the day-one target leaves you short after settling, and that quiet shortfall is one of the most common ways a loose-fill job under-delivers.

Does blown-in insulation air-seal my attic?

No, and that limit is worth understanding. Loose fill slows heat conducting through it, but air keeps moving right past it at top-plate gaps, recessed can lights, and every penetration in the ceiling plane. Blow it over an attic that was never sealed and the material just strains the air leaking by. Air-sealing is its own step and it comes first; the blown layer then handles conduction while the sealing handles leakage.

Can blown-in go on top of my existing insulation?

In most attics, yes. This is what we call a top-off: provided the existing layer is dry, intact, and free of mold or matting, loose fill drapes right over the old material and we add depth until the combined total reaches target. Where the old fill has been walked flat or crushed, we re-fluff or re-level it before blowing, so the fresh layer isn't resting on a dead compressed base.

For a blown-in job, why does hitting an even, verified depth matter so much?

Loose fill earns its keep by wrapping seamlessly around joists and wiring with zero gaps, and that only happens when it goes in at an even depth and the right machine density. Thin edges or under-fluffed sections turn into cold spots. Our process dams the eaves, dials in the blower density, and staples depth-marker rulers across the deck, which makes the installed inches a measurement you can read for yourself rather than a promise you have to take on faith.
