Frequently Asked Questions
What Is Fiberglass Blown-In (Loose-Fill)?
Blown-in fiberglass is a soft, fluffy insulation that’s blown into attics or wall cavities to fill every space. It’s ideal for improving R-value in older homes, sealing small gaps, and creating a uniform thermal layer without major remodeling. Phantom Foam also installs fiberglass batts and hybrid air-seal + blow systems for the most energy-efficient results.
How much insulation should my Houston attic have?
Most homes benefit from R-38 to R-49 in the attic. We verify ventilation and air-seal, then blow to spec so you get the full R-value.
Can you add blown-in over old batts?
Yes. We level existing batts, air-seal leaks, add baffles and dams, then blow to depth. Mixing materials is common when installed correctly.
What’s the difference between batts and blown-in?
Batts are pre-cut blankets for open bays; blown-in is loose for better coverage in attics and dense-pack wall retrofits. We choose based on access and goals.
Will this help with noise?
Yes—especially dense-pack walls and ceiling cavities between floors.
