Blown-In Insulation in Helotes, TX

The measured difference: cellulose delivers about R-3.7 per inch against roughly R-2.5 per inch for fiberglass, so hitting the same R-value target takes noticeably more inches of fiberglass. Each material has documented trade-offs. Cellulose packs denser and resists air drift through the blanket, but it's heavier and settles more; loose-fill fiberglass is lighter, barely settles, and won't wick water if the attic leaks. We work from each material's coverage chart and blow to its own correct install depth, because they are not interchangeable inch-for-inch.

Settling is the documented reason: loose fill compresses after install, cellulose more than fiberglass, so day-one depth and week-six depth are two different measurements. Our method installs above the final R-target so the SETTLED depth still meets spec once the blanket compresses. A crew that blows only to target on day one leaves you short after settling, and that shortfall is one of the most common ways a loose-fill job quietly under-delivers.

No, and understanding this limit is the whole diagnosis. Loose fill is a conductive barrier, slowing heat that moves through it, while air keeps leaking straight through at top-plate gaps, can lights, and penetrations. Blow it over an unsealed attic and the material just filters the escaping air. Air-sealing is its own separate step and it belongs first; the blow addresses conduction, never leakage.

In most cases yes, as a top-off, once we verify the existing layer is dry, intact, and free of mold or matting. Loose fill drapes over old fill without issue, and we blow added depth until the total reaches target. Where the old layer has settled flat or been crushed by foot traffic, we re-fluff or re-level it first, so the new material isn't sitting on a dead, compressed base.

The material's entire advantage rides on it: a seamless blanket that conforms around joists and wiring with no gaps, which holds true only at an even depth and the right machine density. Under-fluffed or thin-at-the-edges fill leaves documented cold spots. Our verification method is concrete: dam the eaves, dial the blower density, and staple depth-marker rulers across the deck, so the installed inches are a measurement you can read yourself rather than a number we promise.
