Blown-In Insulation in Prosper, TX

Cellulose runs about R-3.7 per inch and fiberglass about R-2.5 per inch, so hitting the same R-value target takes noticeably more inches of fiberglass than cellulose. Cellulose packs denser and resists air drifting through the blanket better, but it's heavier and settles more; loose-fill fiberglass is lighter, barely settles, and won't wick water if the attic leaks. We read each material's coverage chart and blow it to its own correct install depth, because inch-for-inch they are not interchangeable.

Because it settles after install, cellulose more than fiberglass, the depth on day one isn't the depth six weeks later. We install above the final R-target so that once the blanket settles, the SETTLED depth still meets spec. Blowing only to the target on day one leaves you short after settling, and that's one of the most common ways a loose-fill job quietly under-delivers.

No, and that's the key limit of the method. Loose fill is a conductive barrier, slowing heat as it moves through, but air still leaks straight past it at top-plate gaps, can lights, and penetrations. Blown over an unsealed attic it merely filters the leaking air. Air-sealing is a separate step that should come first; the blow handles conduction, not leakage.

Usually yes, as a top-off, as long as the existing layer is dry, intact, and neither moldy nor matted. Loose fill drapes right over old fill, and we blow the added depth to bring the total up to target. If the old layer is settled flat or crushed by foot traffic, we re-fluff or re-level it first, so the new fill isn't just resting on a dead, compressed base.

Loose fill's whole advantage is a seamless blanket that conforms around joists and wiring with no gaps, but only when it's installed to an even depth at the right machine density. Under-fluffed or thin-at-the-edges fill leaves cold spots. We dam the eaves, dial in the blower density, and staple depth-marker rulers across the deck, so the installed inches are a measurement you can read rather than a number we promise.

Vertical emphasis — taking the facing to the ceiling in a defined column — is the cheapest effective move. It gives the height something to resolve into.

Sometimes, and it is the most expensive answer because it changes the appliance, the flue and the framing. In very tall rooms it is often the only thing that truly rebalances the space.

On its own, usually not — it tends to disappoint in a room this scale. We would rather tell you that than take the smaller job and have you unhappy with it.
