Fiberglass Insulation in Phoenix, AZ

Two Forms of Fiberglass

Blown loose fill is placed pneumatically and finds its way around framing and obstructions on its own. Batts and rolls are factory-made blankets sized to standard framing spacing. The material is the same glass fiber in both cases; the form decides where it works.

Spray Foam Insulation Phoenix installs both forms across the metro, in homes, additions, commercial build-outs and faced liner systems for metal buildings.

Blown Fill on Attic Floors

Open attic floors over truss framing are blown fill's home ground. The material flows around the chords and cross bracing that make batt placement slow, and depth markers set during the install let the coverage be verified after the fact.

Enclosed cavities take the same material through small access holes, which is how finished walls and garage ceilings get insulated without opening the drywall.

Batts in Open Framing

New construction, additions and remodels expose the framing, and exposed framing is where batts make sense. The cavity is regular, the depth is fixed by the stud, and the install is fast.

Performance depends on fit. Batts get cut around junction boxes and piping rather than stuffed behind them, and pieces are sized to the bay rather than compressed into it. A blanket that is squeezed or shorted does not deliver its label value.

Where Foam Takes Over

Fiberglass filters air rather than stopping it. Where leakage through the assembly is the actual problem, foam or dedicated air sealing has to do that part of the job. Many projects use both materials: foam at the leakage paths, fiberglass as bulk fill everywhere else.

We price the options separately so the tradeoff is visible on paper. Call Spray Foam Insulation Phoenix to talk through your project.
